Highlights of GAO-09-85, a report to the Chairman, Committee on 
Homeland Security, House of Representatives. 

Why GAO Did This Study: 

Numerous incidents around the world have highlighted the vulnerability 
of commercial vehicles to terrorist acts. Commercial vehicles include 
over 1 million highly diverse truck and intercity bus firms. Within the 
Department of Homeland Security (DHS), the Transportation Security 
Administration (TSA) has primary federal responsibility for ensuring 
the security of the commercial vehicle sector, while vehicle operators 
are responsible for implementing security measures for their firms. GAO 
was asked to examine: (1) the extent to which TSA has assessed security 
risks for commercial vehicles; (2) actions taken by key stakeholders to 
mitigate identified risks; and (3) TSA efforts to coordinate its 
security strategy with other federal, state, and private sector 
stakeholders. GAO reviewed TSA plans, assessments, and other documents; 
visited a nonrandom sample of 26 commercial truck and bus companies of 
varying sizes, locations, and types of operations; and interviewed TSA 
and other federal and state officials and industry representatives. 

What GAO Found: 

TSA has taken actions to evaluate the security risks associated with 
the commercial vehicle sector, including assessing threats and 
initiating vulnerability assessments, but more work remains to fully 
gauge security risks. Risk assessment uses a combined analysis of 
threat, vulnerability, and consequence to estimate the likelihood of 
terrorist attacks and the severity of their impact. TSA conducted 
threat assessments of the commercial vehicle sector and has also 
cosponsored a vulnerability assessment pilot program in Missouri. 
However, TSA’s threat assessments generally have not identified the 
likelihood of specific threats, as required by DHS policy. TSA has also 
not determined the scope, method, and time frame for completing 
vulnerability assessments of the commercial vehicle sector. In 
addition, TSA has not conducted consequence assessments, or leveraged 
the consequence assessments of other sectors. As a result of 
limitations with its threat, vulnerability, and consequence 
assessments, TSA cannot be sure that its approach for securing the 
commercial vehicle sector addresses the highest priority security 
needs. Moreover, TSA has not developed a plan or time frame to complete 
a risk assessment of the sector. Nor has TSA completed a report on 
commercial trucking security as required by the Implementing 
Recommendations of the 9/11 Commission Act (9/11 Commission Act). 

Key government and industry stakeholders have taken actions to 
strengthen the security of commercial vehicles, but TSA has not 
assessed the effectiveness of federal programs. TSA and the Department 
of Transportation (DOT) have implemented programs to strengthen 
security, particularly those emphasizing the protection of hazardous 
materials. States have also worked collaboratively to strengthen 
commercial vehicle security through their transportation and law 
enforcement officials’ associations, and the establishment of fusion 
centers. TSA also has begun developing and using performance measures 
to monitor the progress of its program activities to secure the 
commercial vehicle sector, but has not developed measures to assess the 
effectiveness of these actions in mitigating security risks. Without 
such information, TSA will be limited in its ability to measure its 
success in enhancing commercial vehicle security. 

While TSA has also taken actions to improve coordination with federal, 
state, and industry stakeholders, more can be done to ensure that these 
coordination efforts enhance security for the sector. TSA signed joint 
agreements with DOT and supported the establishment of 
intergovernmental and industry councils to strengthen collaboration. 
TSA and DOT completed an agreement to avoid duplication of effort as 
required by the 9/11 Commission Act. However, some state and industry 
officials GAO interviewed reported that TSA had not clearly defined 
stakeholder roles and responsibilities consistent with leading 
practices for collaborating agencies. TSA has not developed a means to 
monitor and assess the effectiveness of its coordination efforts. 
Without enhanced coordination with the states, TSA will have difficulty 
expanding its vulnerability assessments. 

What GAO Recommends: 

GAO is recommending that TSA develop a plan and time frame for 
completing risk assessments, develop performance measures that assess 
the effectiveness of federal commercial vehicle security programs, 
fully define stakeholder roles and responsibilities, and assess its 
coordination efforts. DHS concurred with our recommendations.

The Honorable Bennie G. Thompson: 
Chairman: 
Committee on Homeland Security: 
House of Representatives: 

Dear Mr. Chairman: 

Numerous incidents around the world have highlighted the vulnerability 
and accessibility of commercial trucks and buses to terrorists and 
other persons intending to do harm, including domestic attacks using 
commercial trucks at the Oklahoma City Murrah Federal Building in 1995 
(fig. 1) and the World Trade Center in 1993, as well as bombings using 
trucks of U.S. embassies in Kenya and Tanzania in 1998. Between 1997 
and 2008, there have been 510 terrorist truck and bus bombing attacks 
worldwide resulting in over 6,000 deaths and, due in large part to the 
current conflict in Iraq, there was a large surge of truck bombings 
during 2007. Commercial vehicles play an essential role in moving goods 
and people throughout the country. For purposes of this report, 
commercial vehicles refers to those vehicles used in the commercial 
trucking industry (e.g., for-hire and private trucks moving freight, 
rental trucks, and trucks carrying hazardous materials) and the 
commercial motor coach industry (i.e., intercity, tour, and charter 
buses).[Footnote 1]

[End of figure] 

More than a million commercial trucking companies transport 65 percent 
of the nation's daily freight, including almost 800,000 shipments of 
hazardous materials daily. Commercial buses carry 775 million 
passengers annually, more than commercial aviation carries. The 
openness of the nation's highway transportation system allows these 
vehicles and their operators to move freely and, with the exception of 
commercial trucks carrying hazardous materials, under almost no 
restrictions. The open operational environment, sizeable volume, and 
accessibility of commercial vehicles also presents challenges in 
addressing potential threats to the system. The Department of Homeland 
Security's (DHS) Transportation Security Administration (TSA) has 
primary responsibility for securing the commercial vehicle 
sector.[Footnote 2] Within TSA, the Highway and Motor Carrier (HMC) 
Division is responsible for ensuring highway and motor carrier 
security. The Department of Transportation's (DOT) Pipeline and 
Hazardous Materials Safety Administration (PHMSA) and Federal Motor 
Carrier Safety Administration (FMCSA), state and local law enforcement 
agencies, and private companies that own and operate commercial 
vehicles also have responsibilities related to the security of 
commercial vehicles. PHMSA is responsible for developing hazardous 
materials security regulations, and FMCSA is responsible for enforcing 
those regulations through safety and security inspections. State and 
local governments coordinate with FMCSA as they conduct their own 
safety and security inspections, while private commercial vehicle firms 
are ultimately responsible for personnel, vehicle, and terminal 
security within the commercial vehicle sector. 

Given competing homeland security priorities and limited resources, 
Congress and the executive branch must make difficult policy decisions 
in order to prioritize security efforts and direct resources to the 
areas of greatest risk among all transportation modes and across other 
nationally critical sectors, such as the chemical and energy sectors. 
Within the commercial vehicle sector, federal, state, and local 
agencies and private commercial vehicle firms must also identify and 
invest in appropriate security measures to safeguard the industry while 
supporting other capital and operational improvements. The National 
Commission on Terrorist Attacks upon the United States (the 9/11 
Commission) recommended that the federal government use risk management 
principles to determine how best to allocate limited resources. 
Further, the Intelligence Reform and Terrorism Prevention Act of 2004 
requires DHS to develop risk-based priorities across all transportation 
modes in its National Strategy for Transportation Security.[Footnote 3] 
A risk management approach entails a continuous process of managing 
risks through a series of actions, including setting strategic goals 
and objectives, assessing and quantifying risks, evaluating alternative 
security measures, selecting which measures to undertake, and 
implementing and monitoring those measures. The Secretary of DHS and 
the Assistant Secretary, TSA, have identified that risk-based decision 
making is a cornerstone of departmental and agency policy. 

Homeland Security Presidential Directive 7 (HSPD-7), issued in December 
2003, directed DHS to establish policies and approaches for integrating 
critical infrastructure protection and risk management activities. 
Specifically, federal departments and agencies, working with state and 
local governments and the private sector, are to identify, prioritize, 
and coordinate the protection of critical infrastructure and key 
resources to prevent, deter, and mitigate the effects of deliberate 
efforts to destroy, incapacitate, or exploit them.[Footnote 4] As 
required by HSPD-7, in June 2006, DHS issued the National 
Infrastructure Protection Plan (NIPP), which outlines national goals, 
objectives, milestones, and key initiatives with respect to the 
protection of critical infrastructure and provides a framework for the 
development of sector-specific security plans. In accordance with the 
NIPP and Executive Order 13416, DHS developed the Transportation 
Systems Sector-specific Plan (TSSP) to govern its strategy for securing 
the transportation sector, as well as annexes for each mode of 
transportation, including highway infrastructure and motor carrier 
transportation. The NIPP and TSSP require a strategy based on a risk 
assessment process of considering threat, vulnerability, and 
consequence assessments together to determine the likelihood of 
terrorist attacks and the severity of their impact. 

You expressed interest in the progress TSA has made in setting 
priorities and implementing measures to enhance the security of 
commercial vehicles, as well as the security practices that commercial 
trucking and motor coach industries have implemented. This report 
addresses the following questions: (1) To what extent has TSA assessed 
the security risks associated with commercial vehicles and used this 
information to develop and implement a security strategy? (2) What 
security actions have key government and private sector stakeholders 
taken to mitigate identified risks to commercial vehicle security, and 
to what extent has TSA measured the effectiveness of its actions? (3) 
To what extent has TSA coordinated its strategy and efforts for 
securing commercial vehicles with other federal entities, states, and 
private sector stakeholders? 

To determine the extent to which TSA has assessed the security risks 
associated with commercial vehicles and used this information to 
develop and implement a security strategy, we analyzed strategic 
security planning documents and risk assessment documentation-- 
including assessments of threat, vulnerability, and consequences--and 
interviewed agency officials. Specifically, we reviewed DHS and TSA's 
threat assessments and interviewed officials from TSA's Office of 
Intelligence and HMC. To evaluate TSA's efforts to assess 
vulnerability, we examined the results of its vulnerability 
assessments, known as Corporate Security Reviews (CSRs), attended two 
Missouri Pilot CSRs, and met with TSA HMC officials, FMCSA field 
inspectors, and Missouri state officials to discuss the CSRs. We also 
met with DOT FMCSA officials regarding their security inspection 
programs. To assess TSA's efforts to conduct consequence assessments, 
we interviewed officials from TSA's HMC and DHS's National Protection 
and Programs Directorate. We also reviewed risk assessment and strategy 
documents and interviewed HMC officials to determine the extent to 
which their risk assessments were informing TSA's security strategy, 
and we compared their actions to DHS risk management guidance. 

To identify the security actions key federal government stakeholders 
have taken to mitigate risks to commercial vehicle security, and the 
extent to which TSA has measured the effectiveness of its actions, we 
reviewed agency annual reports, field risk assessment summaries, and 
performance reports, and interviewed officials from TSA, PHMSA, and 
FMCSA. To identify state actions, we interviewed officials of two 
associations representing state transportation and law enforcement 
organizations. We also interviewed officials from eight states and 
conducted site visits at five. We selected these states in a 
nonprobability sample based on certain characteristics, including their 
proximity to critical infrastructure and potential terrorist targets 
such as large population centers, and the amount of hazardous materials 
originating in the state. To identify private industry actions, we 
examined inspections data from TSA, and reviewed documents from 
industry trade associations on the guidance they provided to their 
members. The quality of TSA's CSR inspection data was previously 
assessed by the Missouri Pilot Evaluation. We reviewed the pilot 
evaluation and concurred with its conclusion that the Missouri sample 
was not representative of the commercial vehicle industry in Missouri 
or the industry nationwide. We chose industry associations based on a 
review of the industry and discussions with TSA. We chose 12 industry 
associations that represent trucking firms, owner operators and truck 
drivers, truck manufacturers, truck rental and leasing companies, 
hazardous materials shippers, and intercity and tour bus companies. We 
also interviewed leadership of the Highway and Motor Carrier Sector 
Coordinating Council (SCC), and conducted site visit interviews with 26 
commercial truck and bus companies selected on the basis of 
characteristics including size, location, and other factors. Because we 
selected a nonprobability sample of commercial vehicle firms and 
states, the information we obtained from these interviews and visits 
cannot be generalized to all commercial vehicle companies. However, we 
believe that observations obtained from these visits provided us with a 
greater understanding of the industry's and state's operations and 
perspectives. To assess the extent to which TSA has measured the 
effectiveness of its security actions, we used guidance from the 
Government Performance Results Act (GPRA) and DHS guidelines as 
criteria; assessed TSA planning, budgeting, and performance measurement 
documents; and interviewed agency officials. 

To review TSA's efforts to coordinate its strategy and efforts for 
securing commercial vehicles with other federal entities, we reviewed 
DHS's memorandum of understanding with DOT and subsequent annexes that 
identify the roles and responsibilities of DHS and DOT components 
related to the security of commercial vehicles, and interviewed 
officials from TSA, PHMSA, and FMCSA. In addition, we reviewed statutes 
relating to DHS and DOT roles and responsibilities, as well as related 
regulations and associated comments provided during the rulemaking 
process. To assess TSA's coordination with states, we interviewed state 
officials in the eight states we selected. We also reviewed 
documentation of state law enforcement and transportation associations' 
communication with TSA and interviewed their officials. To assess TSA's 
coordination with private industry, we reviewed documentation of 
coordination and communication and interviewed members of the SCC and 
the 26 private firms we visited. We then discussed a synopsis of these 
agency, state, and industry comments with TSA officials to obtain their 
perspectives. Finally, we compared TSA's efforts to collaborate and 
coordinate with stakeholders to leading practices of collaborating 
agencies.[Footnote 5] 

We conducted this performance audit from October 2006 through February 
2009 in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. For a more 
detailed discussion of our objectives, scope, and methodology, see 
appendix I. 

Results in Brief: 

TSA has taken actions to assess the security risks associated with the 
commercial vehicle sector, including assessing threats, initiating 
vulnerability assessments, and developing security best practices, but 
more work remains to fully assess the security risks of commercial 
trucks and buses, and to ensure that this information is used to inform 
TSA's security strategy. Risk assessment is the process of considering 
threat, vulnerability, and consequence assessments to determine the 
likelihood of terrorist attacks and the severity of their impact. TSA 
has and continues to conduct threat assessments of the commercial 
vehicle sector, and has reported that Vehicle Borne Improvised 
Explosive Devices, or truck bombs, are the most likely tactic. TSA has 
also cosponsored a large number of vulnerability assessments of the 
commercial vehicle sector through a pilot initiative in the state of 
Missouri, known as Corporate Security Reviews (CSRs), and is in the 
process of expanding its CSR program to Michigan and Colorado. In 
addition, TSA has begun gathering evacuation data that could inform 
consequence assessments, and is also in the process of conducting 
threat scenarios of commercial vehicle security risks. Although TSA has 
taken actions to assess risks to the commercial vehicle sector, it can 
further strengthen and complete these efforts. Specifically, TSA's 
threat assessments generally did not identify the likelihood of 
specific threats as required by the NIPP, and the agency has not yet 
developed a plan to regularly provide specific threat likelihood 
estimates. Regarding vulnerability, TSA's contracted evaluation of the 
Missouri CSR pilot program was completed 2 years ago and made a number 
of recommendations to expand and improve the CSR program, which TSA has 
not fully addressed. For example, TSA has not addressed the 
evaluation's recommendation that it draw a more statistically 
representative sample for its CSR interviews. As a result, the agency 
cannot be sure that its CSR efforts will fully identify the 
vulnerabilities of the sector. Standards for internal controls for the 
federal government state that findings and deficiencies reported in 
audits and other reviews should be promptly reviewed, resolved, and 
corrected within established time frames. TSA also has not determined 
the scope, method, or time frame it will use to complete vulnerability 
assessments of the commercial vehicle sector and its diverse firms. 
Without completing industry vulnerability assessments as required by 
HSPD-7 and the NIPP, TSA cannot complete an overall assessment of the 
industry security risks. In addition, TSA has not conducted assessments 
of consequences of a terrorist attack on the commercial vehicle sector, 
or developed a plan to conduct sector wide consequence assessments. The 
agency also has not determined the scope and method required for risk 
assessments for the commercial vehicle sector, specifically the mix of 
expert and field-level risk assessments it intends to use and how it 
plans to integrate the two. Nor has the agency leveraged the risk 
assessments of other sectors to gauge the consequences of truck bomb 
attacks on the nation's critical infrastructure. TSA has identified 
that one of its strategic goals is to inventory the security status of 
the nation's highway and motor carrier systems. Standard practices in 
program and project management include developing a road map, or a 
program plan, to achieve programmatic results within a specified time 
frame or milestones. However, at present, TSA does not have a plan 
specifying the degree to which further risk assessments of the 
commercial vehicle industry are needed and the level of resources 
required to complete these assessments, nor has TSA established a time 
frame for completing its risk assessment efforts. Without a plan and a 
time frame to complete threat, vulnerability, and consequence 
assessments for the commercial vehicle sector, or an existing strategy 
that is based on available intelligence information, TSA cannot be 
assured that its approach for securing the commercial vehicle sector is 
aligned with the highest priority security needs. In lieu of a 
completed risk assessment, TSA leadership has decided to implement a 
current strategy which focuses on examining security risks posed by the 
shipment of hazardous materials. However, available information from 
ongoing risk assessments does not appear to support this emphasis, and 
the basis for TSA's decision for this strategy is unclear. TSA also has 
not completed a report as required by the Implementing Recommendations 
of the 9/11 Commission Act (9/11 Commission Act) on commercial trucking 
security. 

Key government and industry stakeholders have taken actions to 
strengthen the security of the commercial vehicles sector, but TSA has 
not completely assessed the effectiveness of federal actions. At the 
federal level, DHS and DOT have implemented a number of programs 
designed to strengthen the security of the commercial vehicle sector, 
including conducting security assessments and implementing hazardous 
materials security programs. States have also worked individually and 
collaboratively through their state transportation and law enforcement 
associations to strengthen the security of commercial vehicles and 
highway infrastructure, establishing various committees and 
implementing joint initiatives with TSA and DOT. In addition, 
commercial truck and motor coach industry associations we contacted 
reported that they were generally assisting their members to improve 
security by providing them with a variety of best practices guidance. 
Regarding the preparedness of individual firms, the Missouri CSR pilot 
evaluation showed that the more highly regulated firms carrying 
hazardous materials were implementing more security measures to 
mitigate their risks, while truck companies not transporting hazardous 
materials were implementing few of TSA's best security practices. Our 
site visits to 26 commercial truck and bus companies found that most of 
these companies had implemented basic security measures, but the 
prevalence and sophistication of these practices varied. TSA has begun 
developing and using performance measures to assess the progress of 
commercial vehicle security programs, but does not have outcome data to 
monitor how effectively its programs are achieving their intended 
purpose, as suggested by GPRA and the Transportation Sector Security 
Plan. TSA officials agreed that opportunities exist to develop outcome- 
based performance measures for its commercial vehicle security 
programs, and stated that they would like to do so in the future. 
Without outcome measures and data, TSA will not be able to measure its 
success in achieving the ultimate goal of enhancing the security of the 
commercial vehicle sector. Moreover, as we have previously reported, 
GPRA provides a means for agencies to ensure that program strategies 
are mutually reinforcing, and, as appropriate, common or complementary 
performance measures are used. Although TSA officials stated that 
performance data for these programs are important to monitor the 
effectiveness of federal efforts to secure the sector, they lacked an 
agreement to receive performance measurement data for commercial 
vehicle security programs from FMCSA. However, after the 9/11 
Commission Act required TSA and FMCSA to complete an annex to a 
memorandum of understanding (MOU), an agreement was concluded in 
October 2008 which included procedures to implement data sharing. 

While TSA has taken actions to strengthen coordination with federal, 
state, and industry stakeholders related to commercial vehicle 
security, more can be done to ensure that these coordination efforts 
enhance security for the sector. Our previous work has shown that 
leading practices for collaborating agencies include defining a common 
outcome and complementary strategy, agreeing on roles and 
responsibilities, leveraging stakeholder resources, and developing 
mechanisms to monitor, evaluate, and report on the results of the 
collaborative effort.[Footnote 6] DHS and DOT have signed an MOU, which 
established broad areas of responsibility, and TSA signed an additional 
annex with PHMSA to enhance coordination. Moreover, TSA has established 
an intergovernmental council to coordinate with federal and state 
officials and supported the creation of an industry council to gather 
feedback and input regarding the commercial vehicle sector. DOT 
officials expressed general satisfaction with their overall level of 
coordination with TSA. However, without an agreement with FMCSA, TSA 
had made limited progress in leveraging FMCSA resources and resolving 
potentially duplicative security inspections. After the 9/11 Commission 
Act required TSA and FMCSA to complete an annex to the MOU to reduce 
potential duplication of effort, an agreement was concluded in October 
2008. Some state and industry officials we interviewed raised concerns 
about TSA's coordination and communication with the sector on 
developing a security strategy and defining roles and responsibilities 
for the industry. For example, one group of state transportation 
officials stated that they tried to discuss with TSA and DHS what role 
the states play in transportation security, but according to these 
officials, neither agency responded by providing fully defined roles or 
communicating TSA's strategy to secure commercial vehicles. Other state 
officials said they had to delay implementing their own initiatives 
pending TSA clarification of state roles and responsibilities. Although 
TSA has leveraged the resources of the State of Missouri to conduct CSR 
vulnerability assessments, and recently reached agreements to expand 
them to Michigan and Colorado, the agency has made limited progress in 
coordinating the expansion of CSRs to other states. Without enhanced 
coordination, it will be difficult for TSA to expand the CSR approach 
to other states. Finally, TSA stated that it has taken steps to 
interact with industry regarding the security of the sector and has 
also leveraged its expertise to strengthen security. However, the 
agency has not developed a process to monitor the effectiveness of its 
coordination efforts with this very large and diverse sector, 
consistent with leading practices for collaborating agencies. Without 
such a process, TSA will have difficulty enhancing and sustaining 
collaborative efforts and identifying areas for improvement. 

To help strengthen the security of commercial vehicles in the United 
States and leverage the knowledge and practices employed by key federal 
and nonfederal stakeholders, we are recommending that the Assistant 
Secretary of the Transportation Security Administration establish a 
plan and a time frame for completing risk assessments of the commercial 
vehicle sector and use this information to support future updates of 
the Transportation Sector Strategic Plan; clarify the basis for the 
current risk reduction strategy; develop outcome-based performance 
measures, to the extent possible, to assess the effectiveness of its 
programs to enhance the security of the commercial vehicle sector; and 
establish a process to strengthen coordination with the commercial 
vehicle industry, including ensuring that roles and responsibilities of 
industry and government are fully defined and clearly communicated, new 
approaches to enhance communication are considered, and the 
effectiveness of its coordination efforts are monitored and assessed. 
We provided a draft copy of this report to DHS and DOT for review. DHS, 
in its written comments, generally concurred with our findings and 
recommendations and discussed efforts underway to address them. DOT 
provided additional technical comments, which were incorporated as 
appropriate. 

Background: 

Certain characteristics of commercial trucks and buses make them 
inherently vulnerable to terrorist attacks and therefore difficult to 
secure. The commercial trucking and bus industries are open by design, 
with multiple access points and terminals so that vehicles can move 
large numbers of people and volumes of goods quickly. The openness of 
this sector and the large numbers of riders and quantities of goods on 
vehicles with access to metropolitan areas or tourist destinations also 
make them both difficult to secure and attractive targets for 
terrorists because of the potential for mass casualties and economic 
damage and disruption. In addition, the multitude of private commercial 
truck and bus companies and their diversity in size and cargo 
complicate efforts to develop security measures and mitigation 
strategies that are appropriate for the entire industry. 

Between 1997 and 2008 there were 510 terrorist-related commercial truck 
and bus bombing attacks worldwide, killing over 6,000 people, with 106 
bombings occurring during 2007 alone, killing over 2,500 people. Of the 
510 bombings since 1997, 364 have been bus bombings and 146 have been 
truck bombings; 156 have been in Iraq and 354 have been in countries 
other than Iraq. In 2007, the use of truck bombs as a terrorist tactic 
more than tripled and resulted in 2072 deaths.[Footnote 7] While trucks 
were involved in just 29 percent of the bombings since 1997, they 
accounted for 56 percent of the deaths. Vehicle Borne Improvised 
Explosive Devices (VBIEDs) are vehicles loaded with a range of 
explosive materials that are detonated when they reach their target. 
VBIEDs can also be used to explode flammable fuel trucks, and disperse 
toxic substances. Terrorists have used a variety of trucks--rental, 
refrigerator, cement, dump, sewerage, gasoline tanker, trucks with 
chlorine and propane tanks, and fire engines--to attack a broad range 
of critical infrastructure, including police and military facilities, 
playgrounds, childcare centers, hotels, and bridges. Worldwide, 
commercial buses have also been attacked numerous times, including in 
Israel, England, Iraq, the Philippines, Lebanon, Sri Lanka, India, 
Russia, and Pakistan.[Footnote 8] In the United States, terrorists used 
a commercial truck containing fertilizer-based explosives to attack the 
World Trade Center in 1993, killing 6 and injuring 1,000 people. Two 
years later, a similar attack occurred at the Alfred P. Murrah Federal 
Building in Oklahoma City, Oklahoma, killing 168 people and injuring 
more than 800. Terrorists have also targeted overseas U.S. military 
personnel with commercial VBIEDs at the Marine barracks in Lebanon 
(1983), Khobar Towers in Saudi Arabia (1996), and at U.S. embassies in 
Kuwait (1983), Lebanon (1984), Kenya (1998), and Tanzania (1998).

truck or buses since the 1997. See appendix II for more information on

[A] Data on the incidents of truck and bus bombings were based on a 
systematic search of the Global Terrorism Database, Nexis, and Dialog 
databases. GAO determined which databases and search terms were to be 
used through a pilot study which also explored the various potential 
threats to validity and how to mitigate them. To use only the most 
reliable data, we limited the search to 1997 through 2008. Incidents 
directed at troops in combat were not counted; however, incidents 
directed at civilians or other targets in active war zones such as Iraq 
and Afghanistan are included. Bus attacks include attacks on bus 
stations and bus stands. For further information on the methodology and 
results of our database searches, see app. II.

Stakeholder Roles and Responsibilities: 

DHS and DOT share responsibility for securing the commercial vehicle 
sector. Prior to the terrorist attacks of September 11, 2001, DOT was 
the primary federal entity involved in regulating commercial vehicles. 
In response to September 11, 2001, Congress passed the Aviation and 
Transportation Security Act (ATSA) of 2001, which created and conferred 
upon TSA broad responsibility for securing all transportation 
sectors.[Footnote 9] In 2002, Congress passed the Homeland Security 
Act, which established DHS, transferred TSA into DHS, and gave DHS 
responsibility for protecting the nation from terrorism, including 
securing the nation's transportation systems.[Footnote 10] Although TSA 
is the lead agency responsible for the security of commercial vehicles, 
including those carrying hazardous materials,[Footnote 11] DOT 
maintains a regulatory role with respect to hazardous 
materials.[Footnote 12] Specifically, DOT continues to issue and 
enforce regulations governing the safe transportation of hazardous 
materials. In addition, the Homeland Security Act expanded DOT's 
responsibility to include ensuring the security, as well as the safety, 
of the transportation of hazardous materials.[Footnote 13] Accordingly, 
within DOT, PHMSA is responsible for developing, implementing, and 
revising security plan requirements for carriers of hazardous 
materials, while FMCSA inspectors enforce these regulations through 
reviews of the content and implementation of these security plans. 

In 2004, based on a recommendation we made, DHS and DOT entered into a 
memorandum of understanding (MOU) to delineate the agencies' roles and 
responsibilities with respect to transportation security. In 2006, TSA 
and PHMSA completed an annex to the MOU related to the transportation 
of hazardous materials. This annex identifies TSA as the lead federal 
entity for the security of the transportation of hazardous materials, 
and PHMSA as responsible for promulgating and enforcing regulations and 
administering a national program of safety and security related to the 
transportation of hazardous materials. In addition, the 9/11 Commission 
Act requires that, by August 2008, DHS and DOT complete an annex to the 
MOU that would govern the roles of the two agencies regarding the 
security of commercial motor vehicles.[Footnote 14] 

State and local governments also play a key role in securing commercial 
vehicles. States own, operate, and have law enforcement jurisdiction 
over significant portions of the infrastructure--including highways, 
tunnels, and bridges--that commercial vehicles use. Further, state and 
local governments respond to emergencies involving commercial vehicles 
which travel within and through their jurisdictions daily. Many states 
also have departments of homeland security with firsthand knowledge of 
hazardous materials shippers and routing, local smuggling operations, 
and individuals and groups to be monitored for security reasons. Some 
states also have fusion centers that collect relevant law enforcement 
and intelligence information to coordinate the dissemination of alerts 
and assist in emergency response. State transportation and law 
enforcement officials also conduct vehicle safety inspections and 
compliance reviews, sometimes in coordination with FMCSA.[Footnote 15] 

Although all levels of government are involved in the security of 
commercial vehicles, primary responsibility for securing commercial 
vehicles rests with the individual commercial vehicle companies 
themselves. Truck and bus companies have responsibility for the 
security of day-to-day operations. As part of these operations, they 
ensure that company personnel, vehicles, and terminals---as well as all 
of the material and passengers they transport----are secured. Faced 
with tight competition, low margins, and, in some sectors, high driver 
turnover, some industry officials that we interviewed stated that 
devoting resources to security has remained a challenge. A variety of 
national organizations represent commercial trucking and motor coach 
industry interests. Many of these organizations disseminate pertinent 
security bulletin information from DHS and DOT to their members. Some 
have also developed and provided their members with security 
information and tools--such as security check lists and handbooks--to 
meet members' security needs. See appendix III for a list of the major 
industry associations representing the truck and motor coach industries 
interviewed by GAO. 

Legislation and Regulations Governing the Security of Commercial 
Vehicles: 

Although ATSA, passed in November 2001, includes numerous requirements 
for TSA regarding securing commercial aviation, it does not include any 
specific requirements related to the security of land transportation 
sectors. [Footnote 16] However, with regard to all sectors of 
transportation, ATSA generally requires TSA to: 

* receive, assess, and distribute intelligence information related to 
transportation security; 

* assess threats to transportation security and develop policies, 
strategies, and plans for dealing with those threats, including 
coordinating countermeasures with other federal organizations; and, 

* enforce security-related regulations and requirements. 

Other legislation, specifically the USA PATRIOT Act and the 9/11 
Commission Act, requires TSA to take specific actions to ensure the 
security of commercial vehicles. The USA PATRIOT Act provides that a 
state may not issue to any individual a license to transport hazardous 
materials unless that individual is determined not to pose a security 
risk.[Footnote 17] TSA regulations require that drivers who transport 
hazardous materials undergo a security threat assessment that consists 
of an evaluation of a driver's criminal history, immigration status, 
mental capacity, and connections to terrorism to determine if the 
driver poses a security risk.[Footnote 18] The 9/11 Commission Act also 
requires that the Secretary of Homeland Security, by August 2008, 
submit a report to Congress that includes, among other things, a 
security risk assessment on the trucking industry, an assessment of 
industry best practices to enhance security, and an assessment of 
actions already taken by both public and private entities to address 
identified security risks.[Footnote 19] The act also mandates that the 
Secretary develop a tracking program for motor carrier shipments of 
hazardous materials by February 2008.[Footnote 20] With regard to 
intercity buses, the act requires that the Secretary issue regulations 
by February 2009 requiring high-risk, over-the-road bus operators to 
conduct vulnerability assessments and develop and implement security 
plans.[Footnote 21] The act further mandates that the Secretary of 
Homeland Security issue regulations by February 2008 requiring all over-
the-road bus operators to develop and implement security training 
programs for frontline employees, and that the Secretary establish a 
security exercise program for over-the-road bus 
transportation.[Footnote 22] The act also requires DOT to take specific 
actions related to the security of commercial vehicles. For example, 
the Act requires that the Secretary of Transportation, by August 2008, 
analyze the highway routing of hazardous materials, and develop 
guidance to identify and reduce safety and security risks.[Footnote 23] 

DOT's PHMSA has issued regulations intended to strengthen the security 
of the transportation of hazardous materials.[Footnote 24] The 
regulations require persons who transport or offer for transportation 
certain hazardous materials to develop and implement security 
plans.[Footnote 25] Security plans must assess the security risks 
associated with transporting these hazardous materials and include 
measures to address those risks. At a minimum, the plan must include 
measures to (1) confirm information provided by job applicants hired 
for positions that involve access to and handling of hazardous 
materials covered by the security plan, (2) respond to the assessed 
risk that unauthorized persons may gain access to hazardous materials, 
and (3) address the assessed risk associated with the shipment of 
hazardous materials from origin to destination. The regulations also 
require that all employees who directly affect hazardous materials 
transportation safety receive training that provides awareness of 
security risks associated with hazardous materials transportation and 
of methods designed to enhance transportation security. Such training 
is also to instruct employees on how to recognize and respond to 
possible security threats. Additionally, each employee of a firm 
required to have a security plan must be trained concerning the plan 
and its implementation. 

DHS funding for commercial vehicle security consists of a general 
appropriation to TSA for its entire surface transportation security 
program, which includes commercial vehicles and highway infrastructure, 
rail and mass transit, and pipeline, as well as and appropriations to 
the Federal Emergency Management Administration (FEMA) for truck and 
bus security grant programs.[Footnote 26] Annual appropriations to TSA 
for surface transportation security for fiscal years 2006 through 2009 
are presented in table 1.

[End of table] 

The number of TSA full-time employees (FTEs) dedicated to highway and 
motor carrier security--which includes both commercial vehicles and 
highway infrastructure--has remained at about 19 FTEs annually since 
fiscal year 2002.[Footnote 27] 

Commercial Trucking Industry: 

TSA estimates that there are approximately 1.2 million commercial 
trucking companies in the United States. Trucks transport the majority 
of freight shipped in the United States: by tonnage, 65 percent of 
total domestic freight; by revenue, 75 percent. According to TSA, 75 
percent of U.S. communities depend solely on trucking to transport 
commodities. Trucks and buses have access to nearly 4 million miles of 
roadway in the United States. Trucking companies range in size from a 
single truck to several thousand trucks. According to DOT 2004 data, 
which are the most current available, 87 percent of trucking companies 
operated 6 or fewer trucks, while 96 percent operated 20 or fewer. DOT 
estimates that about 40,000 new commercial trucking companies enter the 
industry annually. As of August 2008, nearly 11.9 million commercial 
trucks were registered with DOT. Trucks come in a large variety of 
configurations and cargo body types to perform a wide range of tasks. 
Some trucks are used for local tasks such as construction, landscaping, 
or local package delivery, while others are used for transporting cargo 
over-the-road or for long hauls. For a more complete summary of DOT 
data on commercial trucking and bus firms, trucks and buses, and 
drivers, see appendix V. 

The trucking industry is diverse, involving several different sectors 
and including for-hire and private fleets, truckload and less-than- 
truckload carriers, bulk transport, hazardous materials, rental and 
leasing, and others. For-hire firms are those for which trucking is 
their primary business, while private fleets are generally used to 
support another business activity, such as grocery chains and 
construction. According to a 2002 DOT survey, for-hire trucks 
represented 47 percent of the industry, while private fleets 
represented 53 percent[Footnote 28]. While truckload carriers move 
loads from point to point, less-than-truckload carriers pick up smaller 
shipments and consolidate them at freight terminals. Bulk transport 
firms move bulk commodities such as gasoline, cement and corn syrup in 
large trailers specifically designed for each type of commodity. Truck 
rental and leasing companies also are part of the commercial trucking 
industry. Consumer rental companies rent trucks to walk-in customers 
for short periods of time and represent 15 percent of the rental and 
leasing industry. Commercial rental and leasing companies generally 
lease trucks for a year or longer and account for the remaining 85 
percent of the rental and leasing industry. 

With respect to the transportation of hazardous materials, of an 
estimated 1.2 million commercial vehicle firms, 60,682 are registered 
as hazardous materials carriers, or about 5 percent of the commercial 
vehicle industry, and 1,778,833 drivers are licensed to transport 
hazardous materials.[Footnote 29] Hazardous materials[Footnote 30] are 
transported by truck almost 800,000 times a day, and 94 percent of 
hazardous material shipments are by trucks, which transport 
approximately 54 percent of hazardous materials volume (tons). DOT 
PHMSA classifies hazardous materials under 9 different classes of 
hazards.[Footnote 31] Most hazardous materials shipments by truck 
involve flammable liquids such as gasoline (81.8 percent), followed by 
gases (8.4 percent) and corrosive materials (4.4 percent). Class 6 
toxic poisons include Toxic Inhalation Hazards (TIH) but comprise only 
0.2 percent of hazardous materials transported by truck. The shipment 
of security sensitive hazardous materials such as Toxic Inhalation 
Hazards is of particular concern to TSA, although the agency estimates 
that they represent just .000058 percent of the commercial vehicle 
industry.[Footnote 32] Eighty-one percent of the Toxic Inhalation 
Hazards transported by truck is anhydrous ammonia and 10 percent is 
chlorine. 

Commercial Bus Industry: 

Commercial bus companies represent less than 1 percent of the 
commercial vehicle industry, but according to TSA estimates, carry 775 
million passengers annually. Intercity buses, or motor coaches, include 
buses with regularly scheduled routes, as well as tour and charter bus 
companies. In August 2008, DOT reported that there were 3,948 motor 
coach carriers, with 75,285 buses. Of these carriers, fewer than 100 
are intercity bus companies, which transport passengers from city to 
city on scheduled routes, while the remaining carriers operate tour and 
charter buses. Most bus companies (95 percent) are small operators with 
fewer than 25 buses. Intercity buses, or motor coaches, serve all large 
metropolitan areas and travel in close proximity to some of the 
nation's most visible and populated sites, such as sporting events and 
arenas, major tourist attractions, and national landmarks. A few 
intercity bus carriers also travel internationally to Canada and 
Mexico. According to a study commissioned by DOT, the accessibility and 
open nature of the motor coach industry make it difficult to protect 
these assets, and the level of security afforded to the infrastructure 
of the motor coach industry is relatively low compared to the 
commercial aviation sector, despite the fact that the motor coach 
industry handles more passengers a year.[Footnote 33] 

Risk Management Approach to Guide Homeland Security Investments: 

HSPD-7 directed the Secretary of DHS to establish uniform policies, 
approaches, guidelines, and methodologies for integrating federal 
infrastructure protection and risk management activities. Recognizing 
that each sector possesses its own unique characteristics and risk 
landscape, HSPD-7 designates Federal Government Sector-Specific 
Agencies (SSAs) for each of the critical infrastructure sectors to work 
with DHS to improve critical infrastructure security.[Footnote 34] On 
June 30, 2006, DHS released the National Infrastructure Protection Plan 
(NIPP), which developed--in accordance with HSPD-7--a risk-based 
framework for the development of Sector-Specific (SSA) strategic plans. 
The NIPP defines roles and responsibilities for security partners in 
carrying out critical infrastructure and key resources protection 
activities through the application of risk management principles. 
Figure 3 illustrates the several interrelated activities of the risk 
management framework as defined by the NIPP, including setting security 
goals and performance targets, identifying key assets and sector 
information, and assessing risk information including both general and 
specific threat information, potential vulnerabilities, and the 
potential consequences of a successful terrorist attack. The NIPP 
requires that federal agencies use this information to inform the 
selection of risk-based priorities and continuous improvement of 
security strategies and programs to protect people and critical 
infrastructure through the reduction of risks from acts of terrorism. 

Figure 3: NIPP Risk Management Framework: 

Flowchart.

[End of figure] 

The NIPP risk management framework consists of the following 
interrelated activities: 

* Set security goals: Define specific outcomes, conditions, end points, 
or performance targets that collectively constitute an effective 
protective posture. 

* Identify assets, systems, networks, and functions: Develop an 
inventory of the assets, systems, and networks that comprise the 
nation's critical infrastructure, key resources, and critical 
functions. Collect information pertinent to risk management that takes 
into account the fundamental characteristics of each sector. 

* Assess risks: Determine risk by combining potential direct and 
indirect consequences of a terrorist attack or other hazards (including 
seasonal changes in consequences, and dependencies and 
interdependencies associated with each identified asset, system, or 
network), known vulnerabilities to various potential attack vectors, 
and general or specific threat information. 

* Prioritize: Aggregate and analyze risk assessment results to develop 
a comprehensive picture of asset, system, and network risk; establish 
priorities based on risk; and determine protection and business 
continuity initiatives that provide the greatest mitigation of risk. 

* Implement protective programs: Select sector-appropriate protective 
actions or programs to reduce or manage the risk identified, and secure 
the resources needed to address priorities. 

* Measure effectiveness: Use metrics and other evaluation procedures at 
the national and sector levels to measure progress and assess the 
effectiveness of the national Critical Infrastructure and Key Resources 
protection program in improving protection, managing risk, and 
increasing resiliency. 

TSA Has Begun Conducting Risk Assessments of the Commercial Vehicle 
Sector, but Has Not Completed These Efforts or Fully Used the Results 
to Support Its Security Strategy: 

TSA has taken actions to assess the security risks associated with the 
commercial vehicle sector, including assessing threats, initiating 
vulnerability assessments, and developing best security practices, but 
more work remains to fully assess the security risks of commercial 
trucks and buses, and to ensure that this information is used to inform 
TSA's security strategy. Although TSA has completed a variety of threat 
assessments and is in the process of developing several threat 
scenarios with likelihood estimates, its key annual threat assessments 
do not include information about the likelihood of a terrorist attack 
method on a particular asset, system or network, as required by the 
NIPP. However, in September 2008, TSA reported that in response to the 
9/11 Commission Act mandate that it submit a risk assessment report on 
commercial trucking security TSA was planning to use threat scenarios 
with likelihood assessments for highway and motor carriers. TSA has 
also cosponsored a large number of vulnerability assessments through a 
pilot initiative in the state of Missouri. However, TSA has made 
limited progress and has not established a plan or time frame for 
conducting a vulnerability assessment of the commercial vehicle sector 
nationwide. Moreover, TSA has not determined how it will address the 
June 2006 recommendations of the Missouri Pilot Program evaluation 
report regarding the ways in which future vulnerability assessments can 
be strengthened. As a result, the agency cannot ensure that its CSR 
efforts will fully identify the vulnerabilities of the sector. 
Standards for internal controls in the federal government require that 
findings and deficiencies reported in audits and other reviews be 
promptly reviewed, resolved, and corrected within established time 
frames. [Footnote 35] In addition, TSA has not conducted assessments of 
consequences of a terrorist attack on the commercial vehicle sector, or 
developed a plan to conduct sectorwide consequence assessments. The 
TSSP calls for a sectorwide approach and strategies to managing 
security risks, and TSA has identified one of its strategic goals as 
conducting an inventory of the security status of the nation's highway 
and motor carrier systems. In addition, standard practices in program 
and project management call for developing a road map, or a program 
plan, to achieve programmatic results within a specified time frame or 
milestones. TSA has not completed a sectorwide risk assessment of the 
commercial vehicle sector or determined the extent to which additional 
risk assessment efforts are needed, nor has it developed a plan or a 
time frame for doing so, including an assessment of the resources 
required to support these efforts. In addition, TSA has not fully used 
available information from its ongoing risk assessments to develop and 
implement its security strategy. As a result, TSA cannot be assured 
that its approach for securing the commercial vehicle sector is aligned 
with the highest priority security needs. Moreover, TSA has not 
completed a report as required by the 9/11 Commission Act on various 
aspects of commercial vehicle security. 

TSA Developed Threat Assessments of the Commercial Vehicle Sector, but 
Generally Did Not Identify the Likelihood of Specific Threats as 
Required by the NIPP: 

TSA has and continues to conduct threat assessments of the commercial 
vehicle sector by reviewing known terrorist goals and capabilities, and 
is in the process of strengthening its efforts by developing more 
specific threat likelihood information to inform agency risk assessment 
efforts. TSA's Office of Intelligence (OI) develops a variety of 
products identifying the threats from terrorism, from annual threat 
assessments on each transportation sector to weekly field intelligence 
summaries and daily briefings. OI also disseminates additional threat 
and suspicious incident information to key federal and nonfederal 
stakeholders as needed related to the commercial vehicle sector. To 
date, these threat assessments have found an increase in truck and bus 
terrorist incidents abroad and that VBIEDs were the most likely tactic. 
TSA OI officials stated that they continue to regard common VBIEDs as a 
greater threat than attacks using hazardous materials such as chlorine. 
OI further reported that the July 2005 bus bombing in London 
demonstrated the capability and intent of terrorists to bomb passenger 
buses in Western nations. 

While TSA's threat assessments provide detailed summaries of recent 
attacks and incidents of interest, and are useful to TSA in informing 
its strategy for securing commercial vehicles, they do not include 
information on the likelihood of various types of threats. The NIPP 
requires that in the context of terrorist risk assessments, the threat 
component of the analysis be calculated based on the estimated 
likelihood of a terrorist attack method on a particular asset, system, 
or network.[Footnote 36] The estimate of this likelihood is to be based 
on an analysis of intent and capability of a defined adversary, such as 
a terrorist group. However, TSA has not included likelihood estimates 
in its annual threat assessments for the highway and motor carrier 
sector.[Footnote 37] In 2006, TSA developed rankings of the likelihood 
of various tactics--such as attacks using VBIEDs, VBIED-assisted 
hazardous materials, and other threats--for highway and commercial 
vehicles. However, TSA subsequently excluded these likelihood 
assessments in its 2008 annual threat assessment for the highway sector 
and did not provide us with the rationale for this decision. OI told us 
that it developed likelihood estimates for specific threat scenarios 
used in the draft National Transportation Sector Risk Assessment 
(NTSRA). NTSRA is being conducted by TSA to assess risks across the 
entire U.S. transportation system and contains nine high-level 
scenarios and threat likelihood estimates related to commercial 
vehicles. Of these high-level scenarios, eight involve VBIEDs, and one 
involves hazardous materials. OI rated the intent and capability of 
terrorists to perform each threat scenario to provide their estimate of 
the relative likelihood of each scenario. However, TSA officials could 
not identify when the NTSRA will be finalized.[Footnote 38] In 
addition, in June 2008, OI reported that it would provide likelihood 
assessments for threat scenarios that were to be conducted in response 
to a mandate in the 9/11 Commission Act that DHS submit a risk 
assessment report on the commercial trucking sector. 

While more extensive threat scenarios are being developed for the 
commercial vehicle sector, including likelihood estimates, TSA's annual 
threat assessments do not include information on the likelihood of 
threat. HMC officials stated that this lack of specific threat 
information continues to challenge agency risk managers. Without more 
information on the likelihood of the various threats, there is limited 
assurance that TSA is focusing its efforts on the activities that pose 
the greatest threat. Officials stated that they may incorporate 
likelihood estimates in the annual highway and motor carrier threat 
assessments in the future, but did not have specific plans to do so. 

TSA Has Begun to Conduct Industry Vulnerability Assessments of the 
Commercial Vehicle Sector, but Its Efforts Are in the Early Stages: 

TSA has begun conducting vulnerability assessments of the commercial 
vehicle sector, but its efforts are in the early stages. In addition, 
the agency has not determined the extent to which additional 
vulnerability assessments are needed, and does not have a strategy or 
time frame for assessing sectorwide vulnerabilities. HSPD-7 requires 
each Sector-Specific Agency to conduct or facilitate vulnerability 
assessments of its sector. In addition, the NIPP states that DHS is 
responsible for ensuring that comprehensive vulnerability assessments 
are performed for critical infrastructure and key resources that are 
deemed nationally critical, and the TSSP further emphasizes a 
sectorwide system-based approach to risk management. To determine the 
vulnerability of commercial vehicles as targets or as weapons to attack 
critical infrastructure in the United States, TSA has begun conducting 
vulnerability assessments known as Corporate Security Reviews (CSRs). 
TSA initiated the CSR program in November 2005 to: (1) develop best 
practices for securing the commercial vehicle industry through 
discussions with carrier representatives and site visits to carrier 
facilities; (2) collect and maintain data that will allow TSA HMC to 
assess various aspects of security across the trucking and motor coach 
industries through statistical analysis of survey data; (3) identify 
security gaps and opportunities for improvement; (4) promote security 
awareness and collaboration with the commercial vehicle industry; (5) 
provide guidance to motor carriers on their relative level of risk 
exposure; and (6) determine the costs and benefits of risk mitigation 
activities. 

As of September 2008, TSA had conducted 100 CSRs of motor carriers, 
including 15 motor coach companies, 20 school bus companies/districts, 
and 65 trucking companies.[Footnote 39] These CSRs were of large firms 
that were identified by industry stakeholders as having the best 
security practices in the industry and that agreed to participate in 
the CSRs on a voluntary basis. TSA conducts these reviews by sending 
teams of two to four people from TSA headquarters to a trucking or bus 
company, for one or two days, to analyze the company security plan and 
mitigation procedures, and make informal recommendations to strengthen 
security based on a draft of best security practices TSA developed. At 
the conclusion of the CSRs, TSA prepares summary reports of its 
findings and informal recommendations. TSA also developed a draft best 
security practices in February 2006 for trucking firms based on the 
results of early CSRs, as well as on TSA staff expertise, industry 
stakeholder input, and best security practices from other 
transportation sectors such as rail and pipeline, according to 
officials. [Footnote 40] These draft best practices include measures 
companies can take to conduct threat, vulnerability, and consequence 
assessments. They also provide guidance on developing a security plan 
and strengthening personnel security, training, hazardous materials 
storage, physical security countermeasures, cyber security, and 
emergency response exercises. However, according to TSA officials, the 
agency has delayed issuing these draft best practices in final form 
until it can complete and incorporate public and industry comments on 
draft security guidance specifically for carriers of hazardous 
materials.[Footnote 41] The 9/11 Commission Act requires that DHS, by 
August 2008, submit a report to Congress that includes, among other 
things, an assessment of trucking industry best practices to enhance 
security. TSA reported that as of September 2008, it had not finalized 
these best practices, but they hoped to complete a template within 4 
months. Officials stated that they plan to develop a flexible list of 
best practices that firms can adapt based on their line of work, size, 
and circumstances. 

TSA began a second CSR effort in April 2006 through a pilot project 
with the state of Missouri which greatly expanded the number of firms 
reviewed, and extended the reviews to smaller, more diverse firms. 
Objectives of the pilot were to promote security awareness, collect 
information on the security status of participating firms, and promote 
public and private collaboration among federal, state, and private 
sector stakeholders. TSA partnered with the State of Missouri, FMCSA's 
Motor Carrier Safety Assistance Program, and the Commercial Vehicle 
Safety Alliance (CVSA) to train Missouri state safety inspectors to 
conduct these CSRs.[Footnote 42] DOT funded the CSRs and assisted 
Missouri in the selection of firms to be reviewed and interviewed. The 
CSRs performed by TSA headquarters staff were of large companies known 
to have more robust security measures in place, while the Missouri CSRs 
were generally conducted on small firms that are most common in the 
industry. Reviewing the security practices of these small firms can 
require inspectors to travel to remote locations all over the state. 
For example, one Missouri CSR we attended assessed a small landscaping 
company with 12 trucks, while another CSR assessed an owner-operator 
with a single truck in front of his house (fig. 4). Although these 
reviews remained voluntary, they were conducted in conjunction with 
mandatory safety reviews that Missouri inspectors routinely conduct on 
commercial vehicle trucking and motor coach firms. Motor carriers were 
selected for Missouri CSRs based on either their safety records as 
evaluated by FMCSA, or because they were newly registered 
firms.[Footnote 43] TSA officials stated that partnering with the 
state's safety inspections enabled TSA to review a more diverse group 
of firms than it did during the original CSRs. Typically, the Missouri 
pilot CSRs involved site visits with structured interviews using a 
questionnaire based on TSA's draft best security practices, and 
generally lasted less than an hour compared to one or two days as was 
the case with the original CSRs. The Missouri CSR pilot concluded in 
February 2007; however, TSA has continued to partner with Missouri and 
FMCSA to implement a permanent CSR program in the state. TSA told us 
that as of September 2008, 3,420 CSRs had been completed in Missouri.

[End of figure] 

In September 2006, TSA awarded a contract to evaluate the extent to 
which the Missouri CSR pilot program met its objectives, and whether 
the firms reviewed had implemented effective security measures. The 
report reviewed the 1,251 CSRs conducted by Missouri inspectors from 
April 2006 through February 2007, including 1,231 trucking companies 
(98.4 percent), 18 motor coach companies (1.4 percent), and 2 school 
bus operators (0.2 percent). The evaluation reviewed each firm's 
responses to the CSR questionnaire and assigned it an overall security 
score based on the security measures the firm reported having in place 
that were consistent with TSA's draft best security practices. The 
contractor reported on the results of the study in June 2007 and 
concluded among other things, that: 

* the interviewed carriers did not have extensive security procedures 
in place; 

* small carriers and owner operators had implemented fewer security 
measures than larger carriers; and: 

* hazardous materials carriers identified by the contractor had 
implemented most of the security measures on the TSA CSR questionnaire. 

The evaluation report also found that while both motor coaches and 
nonpassenger motor carriers had low scores, motor coaches scored 
somewhat higher than nonpassenger motor carriers. The report concluded 
that the program had achieved its objectives of promoting security 
awareness, collecting information on the security status of 
participating commercial vehicle firms, and promoting public and 
private sector collaboration among federal, state, and private sector 
stakeholders. However, the report also concluded that the Missouri 
sample was not representative of the commercial vehicle industry in 
Missouri or of the industry nationwide. The report further concluded 
that since the CSRs were based on best practices developed for much 
larger firms, the CSR data did not completely reflect overall security 
practices and capabilities for small carriers. Missouri officials we 
interviewed concurred that the CSR sample was not representative of 
Missouri firms since the majority of carriers that do not encounter 
safety problems would not be included in their CSR reviews. The 
evaluation report of the Missouri CSR pilot made a number of 
recommendations to TSA to expand and improve the CSR program. These 
recommendations included that TSA: 

* review and address CSR pilot program deficiencies; 

* develop a set of best practices and baseline security standards that 
is risk-based and appropriate for different sizes and types of firms; 

* improve the CSR questionnaire to make it more effective in capturing 
security practices and vulnerabilities of both small and large 
carriers; 

* develop a deployment strategy to expand the Missouri pilot program to 
other carriers and other states; 

* develop a statistically sound methodology for selecting companies for 
CSRs as it evaluates the commercial vehicle industry nationwide by 
conducting a random sample of motor carriers;[Footnote 44] 

* work with FMCSA to leverage each other's resources and possibly merge 
security inspection programs; and: 

* develop a CSR Web portal to provide a more tailored CSR questionnaire 
to address different industry sector security needs. 

Two years after these recommendations were made, TSA has taken limited 
steps to implement them, although officials stated that they were 
continuing to review the recommendations. As a result, the agency 
cannot ensure that its CSR efforts will fully identify sector 
vulnerabilities. Standards for internal controls in the federal 
government require that findings and deficiencies reported in audits 
and other reviews be promptly reviewed, resolved, and corrected within 
established time frames.[Footnote 45] The Missouri evaluation report's 
recommendation that TSA develop a statistically sound methodology for 
selecting companies to review was consistent with TSA's original goal 
that CSRs collect data that enable statistical analysis. In September 
2008, TSA officials stated that they had worked out agreements with 
Michigan and Colorado to begin conducting CSRs in these states, 
beginning with training officers in October 2008. However, TSA did not 
have a plan in place or time frame for assessing industry-wide 
vulnerabilities. The lead official for risk assessment with TSA HMC 
stated that the agency would like to conduct a vulnerability assessment 
of a valid nationwide sample of the commercial vehicle industry, but 
that it lacked the resources to do so. TSA officials further stated 
that to further expand its CSR efforts, it has initiated a program to 
train Federal Security Director [Footnote 46] personnel (FSDs) at 3 
airports to conduct CSRs on commercial vehicles in the airports' 
surrounding areas. Officials told us that FSDs had completed 5 CSRs 
during fiscal year 2008. 

Without completing industry vulnerability assessments as required by 
HSPD-7 and the NIPP, TSA cannot complete an overall assessment of the 
industry security risks. For example, instead of assessing the 
vulnerabilities of the entire commercial vehicle sector, at the 
direction of TSA management, TSA HMC is currently focusing all of their 
CSR efforts on the hazardous materials transportation sector.[Footnote 
47] However, TSA's pilot study on Missouri firms found that hazardous 
materials transportation companies reviewed by the contractor performed 
much better than other companies in terms of implementing security 
measures to mitigate potential vulnerabilities. 

TSA Has Not Begun to Conduct Consequence Assessments of the Commercial 
Vehicle Sector: 

TSA has collected some relevant information necessary for estimating 
the impact of potential attacks involving the commercial vehicle 
sector, but has not conducted consequence assessments of potential 
terrorist attacks or leveraged the consequence assessment efforts of 
others. The DHS NIPP defines consequence assessment as the worst 
reasonable adverse impact of a successful terrorist attack. According 
to the NIPP, risk assessments should include consequence assessments to 
measure the negative effects on public health and safety, the economy, 
public confidence in institutions, and the functioning of government 
that can be expected if an asset, system, or network is damaged, 
destroyed, or disrupted by a terrorist attack. The TSA's TSSP also 
requires that risk analysis include a consideration of consequences. 
Terrorism involving commercial vehicles can affect a broad range of 
targets, including not only trucks and buses, but also freight and 
passengers, terminals, truck stops, and rest areas. In addition to the 
commercial vehicle system being attacked, commercial vehicles can be 
used to attack other assets. When used as VBIEDs with explosives or 
fuel, for example, commercial vehicles can be used to target highway, 
buildings, and other critical infrastructure. A powerful truck bomb can 
destroy from a considerable distance. For example, Khobar Towers was 
attacked from 80 feet away (fig. 5).

[End of figure] 

Truck VBIED attacks can also target large numbers of people, as was the 
case with the coordinated attack of several truck bombs in Northern 
Iraq on August 14, 2007, that killed approximately 500 people, or to 
assassinate individuals such the former Lebanese Prime Minister Rafik 
Hariri. Worldwide, buses have been the target of bombings---some 
involving suicide bombers---on numerous occasions, such as the attack 
on former Prime Minister Benazir Bhutto at a mass rally in Pakistan. 

TSA officials stated that they cannot conduct consequence assessments 
of the commercial vehicle sector because truck bombs can be used to 
attack most of the nation's critical infrastructure. Accordingly, 
officials stated that the number of potential consequences of terrorist 
attacks is too great to practically assess. Although TSA has not 
conducted consequence assessments of the commercial vehicle sector, the 
agency has acquired data from the Bureau of Alcohol, Tobacco and 
Firearms (ATF) and the U.S. Army on evacuation distances for various- 
sized shipments of explosives and flammable substances, and PHMSA's 
Emergency Response Guidebook for first responders to hazardous 
materials incidents that could be applied to future consequence 
assessments.[Footnote 48] TSA officials acknowledged that obtaining 
data on evacuation distances is only a first step in conducting 
consequence assessments. Evacuation distance provides one measure of 
the potential consequences of a terrorist attack by defining the danger 
zone surrounding an attack by a particular type and size of explosive 
or flammable materials. For example, according to U.S. Army data, the 
building evacuation distance for such a worst case scenario truck bomb 
would be a minimum of 1,570 feet, and the minimum outdoor evacuation of 
people would be 7000 feet. Using another example, a fireball from a 
fuel truck can threaten both structures and people; accordingly, ATF 
guidance suggests a minimum evacuation distance of 6,500 feet. In 
comparison, a tank truck of anhydrous ammonia, which represents 81 
percent of Toxic Inhalation Hazard (TIH) shipments, has a smaller 
recommended standoff distance of 2,112 feet, and the recommended 
standoff distance for chlorine, which is the next most common form of 
Toxic Inhalation Hazard, is 3,168 feet. However, other guidance, such 
as the PHMSA's Emergency Response Guidebook, provides different data 
based on initial isolation distances and much larger maximum nighttime 
protective action distances. TSA reported that it is working with 
various federal partners and industry stakeholders to establish a 
uniform and scientific assessment of potential consequences of VBIEDs 
and the discharge of TIH materials. Although TSA has not conducted 
consequence assessments of the commercial vehicle sector, OI officials 
stated that, in their judgment, the likely consequences of common VBIED 
attacks were greater than VBIED attacks using TIH materials because 
attempts to date to use VBIEDs to vaporize chlorine into a gaseous 
inhalation hazard have been largely unsuccessful, have caused little 
damage, and resulted in few casualties. On the other hand, according to 
officials, VBIEDs using a number of different explosives and incendiary 
materials have repeatedly been successfully used to kill people. 

TSA officials stated that the agency also has not leveraged DHS's 
ongoing nationwide risk assessment efforts to obtain consequence 
information. For example, recognizing that each sector of our country's 
critical infrastructure possesses its own unique characteristics, 
operating models, and risk landscape, pursuant to HSPD-7, the NIPP 
designates 18 critical infrastructure sectors and the agencies 
responsible for each of the sectors to work with DHS to implement a 
risk management framework for the sector and develop protective 
programs. Each of the 18 sectors has issued Sector Annual Reports 
(SARs) of their risk management activities, including consequence 
assessments, which HMC could draw upon to support the assessment of 
VBIED and hazardous materials consequences for other critical 
infrastructure sectors. For example, the 2007 sector annual reports 
identified the following for select sectors: 

Commercial Nuclear Power Sector: The Department of Energy employs a 
Comprehensive Review Program to analyze facilities that it considers 
potential terrorist targets. The Nuclear Sector Annual Report indicated 
that as of May 2007, reviews had been completed of the vulnerabilities 
and potential consequences of an attack on 52 of 65 commercial nuclear 
reactors. 

Dams Sector: The 2007 Dams Sector Annual Report identified that all 
security measures were in place at 152 of 254 Army Corps of Engineers 
dams, and the Federal Energy Regulatory Commission reported having 
completed risk assessments on its 1,200 most security-sensitive dams. 
The report also called for improved blast-damage estimates for VBIEDs 
on certain dams and levees that are potential targets for terrorist 
attacks. 

The Chemical Sector: The 2007 Chemical Sector Annual Report, which was 
based in part on industry risk assessments, identified that VBIEDs are 
a particular concern because of their portability, size, and potential 
to cause grave damage. 

In addition, DHS's 2007 Strategic Homeland Infrastructure Risk 
Assessment (SHIRA) assessed the highest risk scenarios targeting the 
nation's 18 critical infrastructure/key resources sectors, and 
highlighted attack methods with cross-sector implications. The SHIRA 
used threat assessments from the intelligence community and 
vulnerability and consequence assessments from the SSAs to identify the 
attack methods that pose the highest risk to the respective sectors. 
TSA HMC could use the SHIRA data to identify which sectors are most at 
risk from VBIEDs and hazardous materials and then coordinate with those 
SSAs on their vulnerability and consequence assessment efforts. TSA HMC 
could also use a variety of other relevant assessments to obtain 
consequence information. These include the agency's Aviation Domain 
Risk Assessment which also considers consequences for a wide range of 
attack scenarios including VBIEDs, the Department of Energy's risk 
assessments of nuclear weapons facilities, and the Nuclear Regulatory 
Commission's assessments of commercial nuclear power plants. Similar 
information is also available from the Federal Risk Assessment Working 
Group, a federal risk assessment information clearinghouse that shares 
information about completed and ongoing risk assessments through 
regular meetings and a Web portal. TSA did not comment on why it has 
not developed a plan for completing consequence assessments, or why it 
was not leveraging the analysis of potential consequences included in 
these risk assessments. 

An Incomplete Risk Assessment Impedes TSA's Ability to Identify 
Effective Risk Reduction Efforts: 

As discussed earlier in this report, TSA has identified one of its 
strategic goals as taking an inventory of the security status of the 
nation's highway and motor carrier systems, but it has not developed a 
plan or a time frame for completing a risk assessment of the commercial 
vehicle sector. Based on general guidance in the NIPP, the TSSP states 
that TSA's plan for risk assessment should use a combination of both 
expert and field-level risk assessment techniques to guide its risk 
management efforts. Expert risk assessments are based on national risk 
priorities and strategic risk objectives, scenario analyses and the 
expert judgment of agency officials, national assessments, and annual 
threat assessments. Field-level risk assessments include state and 
local assessments, and field inspections such as TSA's CSRs and DOT 
Security Contact Reviews (SCRs).[Footnote 49] Expert assessments and 
field assessments have the same goal of identifying where the greatest 
risk mitigation measures are needed. 

As previously discussed, TSA is conducting nine high-level scenarios 
related to commercial vehicles, and has contracted to have more threat 
scenarios conducted to assess commercial trucking security risks in 
response to a mandate in the 9/11 Commission Act.[Footnote 50] While 
these expert assessments, if implemented effectively, should give TSA 
insights into the security risks of the industry, they will likely 
provide limited information on what sectors or companies are most at 
risk and what mitigation practices are currently in place, unless they 
are further supported by field-level risk assessments consistent with 
the TSSP.[Footnote 51] 

As stated previously, TSA is in the early stages of conducting CSRs and 
the majority of CSRs have to date been conducted in a single state, 
Missouri. Although TSA is working to expand both its threat scenarios 
and CSRs, progress to date has been limited. TSA also has not reported 
on the scope and method of risk assessments required for the commercial 
vehicle sector. Specifically, it has not reported what mix of expert 
and field-level risk assessments it intends to use and how it plans to 
integrate the two. 

Standard practices in program and project management include developing 
a road map, or a program plan, to achieve programmatic results within a 
specified time frame or milestones.[Footnote 52] TSA officials 
recognize that the agency needs more complete and accurate risk 
assessment information to inform its security strategy. However, TSA 
has not developed a plan or a time frame for completing a risk 
assessment of the commercial vehicle sector, including the level of 
resources required to complete the assessment and the appropriate scope 
of the assessment including determining the combination of threat 
scenarios and field-level vulnerability assessments it intends to use. 

The NIPP requires that it and the TSSP be reviewed and undergo periodic 
interim updates as required, and reviewed and reissued every 3 years or 
more frequently as needed and directed by the Secretary of Homeland 
Security. Accordingly, the TSSP states that it will undergo periodic 
updates and eventually align with the NIPP triennial update cycle. The 
Highway Infrastructure and Motor Carrier Modal Annex also states that 
the Government Coordination Council (GCC) and SCC are to submit 
revisions to the annex on an annual basis, and the GCC and SCC are to 
conduct a complete revision of the annex every 3 years. HMC began its 
revision process by updating the TSSP Highway Infrastructure and 
Motorcarrier Annex in 2008 to allow time for the revised strategy to be 
reviewed by the GCC, SCC, and various working groups and will submit it 
for review by the third quarter of 2009. The quality of this and future 
revisions of the annex will depend in large measure on the progress of 
risk assessments of the commercial vehicle sector and their utilization 
by TSA managers to inform their risk mitigation efforts. 

HMC officials stated that without complete risk assessments, they were 
directed by TSA and DHS leadership to base their strategy for securing 
the commercial vehicle sector on an examination of the security risks 
posed by the shipment of hazardous materials. However, agency officials 
could not identify why TSA and DHS leadership made this distinction, 
and the rationale for this directive is unclear. HMC officials also 
cited several additional reasons for focusing their security efforts on 
commercial vehicles transporting hazardous materials, including the 
professional judgment of its staff in the motor carrier industry; risk 
assessments TSA conducted for other transportation sectors, 
particularly rail; and legislative requirements, in particular the USA 
PATRIOT Act. However, the applicability of rail risk assessments to 
highways is unclear because VBIEDs trucks can directly access and 
attack most buildings in the United States, whereas rail cannot. Rail 
shipments also typically ship freight, including Toxic Inhalation 
Hazards, in far larger quantities than can be carried on a truck. 
Regarding congressional direction, the USA PATRIOT Act required TSA to 
perform a background check for all applicants for an endorsement of 
their commercial driver's licenses to allow them to carry hazardous 
materials, but did not direct TSA to focus its commercial vehicle 
security efforts on hazardous materials. Moreover, available risk 
assessment information suggests alternatives or additions to the 
agency's current focus on commercial vehicle transport of hazardous 
materials. TSA OI officials have consistently reported that VBIEDs are 
a greater threat to the United States than hazardous materials, 
including Toxic Inhalation Hazards. In addition, the evaluation of the 
Missouri CSR found that truck companies that transport hazardous 
materials stood out from other truck companies as having implemented 
most of TSA's security procedures, and concluded that hazardous 
materials transporting companies were leaders related to the commercial 
vehicle sector. In addition, in October 2007 DHS Secretary Chertoff 
stated that IEDs remained a terrorist weapon of choice since they were 
easy to make, difficult to defend against, and could cause untold 
destruction. TSA OI officials stated that they continue to regard 
common VBIEDs as a greater threat than attacks using hazardous 
materials such as chlorine. Evacuation data also suggest that VBIEDs 
can have potentially broader impact than trucks carrying many forms of 
Toxic Inhalation Hazards. Without an existing strategy that is based on 
available risk assessment information, TSA cannot be assured that its 
current approach, which is focused on hazardous materials, is aligned 
with the highest priority security needs of the commercial vehicle 
sector. 

Government and Industry Have Taken Actions to Strengthen the Security 
of Commercial Vehicles, but TSA Has Not Completely Assessed the 
Effectiveness of Its Actions: 

Key government and industry stakeholders have taken actions to 
strengthen the security of the commercial vehicles sector, but TSA has 
not assessed the effectiveness of its actions. At the federal level, 
DHS and DOT have implemented a number of programs designed to 
strengthen commercial vehicle security, particularly programs for the 
protection of hazardous materials. States, individually and 
collectively, through their state transportation and law enforcement 
associations, have also worked to strengthen the security of commercial 
vehicles. In addition, most of the private truck and motor coach 
industry associations we contacted stated that they were assisting 
their members in strengthening security by providing those members with 
guidance on best practices. TSA also contracted for an evaluation of 
the Missouri pilot CSRs that found the industry security practices were 
not extensive, but noted that the sample of firms in the pilot was not 
representative of the entire industry. Our site visits to 26 commercial 
truck and bus companies found that most had implemented basic security 
measures, including some form of personnel security and background 
checks, terminal security, locks and access controls, trailer seals, 
and communications and tracking equipment. TSA has begun developing 
output-based performance measures to gauge progress on achieving 
milestones and other program activities for its security programs, but 
the agency has not developed measures and data to monitor outcomes, 
that is, the extent to which these programs have mitigated security 
risks and strengthened commercial vehicle security. The TSSP identifies 
that performance measures of strategic goals and objectives should be 
outcome-based, but notes that interim output measures may be used 
during the early years of the program when baseline data on the 
program's performance are being acquired. Without more complete 
performance measures, TSA will be limited in assessing the 
effectiveness of federal commercial vehicle security programs. TSA 
officials agreed that opportunities exist to develop outcome-based 
performance measures for its commercial vehicle security programs, and 
stated that they would like to do so in the future. 

The Federal Government, States, and Private Industry Have Taken Action 
to Enhance the Security of Commercial Vehicles: 

A variety of federal programs have been implemented to enhance the 
security of the commercial vehicle sector. Several of these programs 
have been implemented by TSA and other DHS components, others by DOT, 
and several jointly by DHS and DOT. Overall, these programs are 
designed to assess commercial vehicle industry security risks, develop 
guidance on how to prevent and deter attacks, improve security planning 
for an effective response to a potential terrorist attack, enhance cost-
effective risk mitigation efforts, and support research on commercial 
vehicle security technology. States, both individually and as members 
of transportation alliances with other states, have expanded their 
activities to secure the commercial vehicle sector as a part of broader 
homeland security activities. In addition, many commercial vehicle 
companies receive guidance on security awareness and best practices 
from industry associations. According to TSA's pilot study of CSRs in 
Missouri, except for firms transporting hazardous materials, most 
commercial vehicle companies have implemented a limited number of 
security measures. 

DHS and DOT Security Programs: 

In addition to CSRs, TSA and other DHS components have a number of 
programs underway designed to strengthen the security of commercial 
vehicles: the Truck Security Grant Program (TSP), the Intercity Bus 
Security Grant Program, Security Action Items (SAIs), and Hazardous 
Materials Driver Background Check Program. The TSP provides grants that 
fund programs to train and support drivers, commercial vehicle firms, 
and other members of the commercial vehicle industry in how to detect 
and report security threats, and how to avoid becoming a target of 
terrorist activity. TSP is administered by DHS's Federal Emergency 
Management Agency's Grant Programs Directorate. From fiscal years 2004 
through 2008, the principal activity funded by the TSP was the American 
Trucking Associations' Highway Watch Program, which provided drivers 
with security awareness training and support. In May 2008, however, a 
new grantee was selected.[Footnote 53] DHS also established an 
Intercity Bus Security Grant Program to distribute grant money to 
eligible stakeholders for protecting intercity bus systems and the 
traveling public from terrorism. Current priorities focus on enhanced 
planning, passenger and baggage screening programs, facility security 
enhancements, vehicle and driver protection, and training and 
exercises. In addition, TSA is consulting with industry stakeholders 
and PHMSA to develop SAIs, or voluntary security practices and 
standards, intended to improve security for trucks carrying security- 
sensitive hazardous materials. The SAIs are intended to allow TSA to 
communicate the key elements of effective transportation security to 
the industry as voluntary practices, and TSA will use CSRs to gauge 
whether voluntary practices are sufficient or if regulation is needed. 
TSA released its voluntary SAIs for hazardous materials carriers in 
June 2008. For example, it recommended using team drivers for shipments 
of the most security sensitive explosives, toxic inhalation hazards, 
poisons, and radioactive materials. [Footnote 54] 

The USA PATRIOT Act passed in October 2001 prohibited states from 
issuing Hazardous Materials Endorsements (HME) for a commercial 
driver's license to anyone not successfully completing a background 
check. In response, DHS developed rules regarding how the background 
checks will be conducted and implemented a hazardous materials driver 
background check assessment program to determine whether a driver poses 
a security risk.[Footnote 55] We have previously reported on the 
problem of drivers who have job-hopped to circumvent the drug testing 
results associated with background checks, including hazardous 
materials drivers.[Footnote 56] As of October 2008, TSA had completed 
background checks for 990,961 out of approximately 2.7 million 
hazardous materials drivers, and 8,699 applicants have been denied HMEs 
since the beginning of the program. 

In addition to DHS, at the federal level, DOT has several commercial 
vehicle security programs underway: Security Contact Reviews (SCR), 
Security Sensitivity Visits (SSV), and the Hazardous Materials Safety 
Permit Program. FMCSA conducts SCRs, or compliance reviews, of 
commercial vehicle firms carrying hazardous materials.[Footnote 57] 
PHMSA regulations require shippers and carriers of certain hazardous 
materials to develop and implement security plans. [Footnote 58] At a 
minimum, these plans must address personnel, access, and enroute 
security. FMCSA SCRs review company security plans as part of ongoing 
safety inspections. FMCSA also conducts SSVs, or educational security 
discussions, with carriers of small amounts of hazardous materials that 
do not require posting hazardous materials placards on their trucks. As 
of September 2008, FMCSA had conducted 7,802 SCRs and 13,411 SSVs since 
the inception of the programs. Federal law also directed DOT to 
implement the Hazardous Materials Safety Permit Program to produce a 
safe and secure environment to transport certain types of hazardous 
materials.[Footnote 59] The Hazardous Materials Safety Permit Program 
requires certain motor carriers to maintain a security program and 
establish a system of enroute communication. 

In addition to CSRs, TSA and DOT also work collaboratively on several 
projects involving the security of commercial vehicles, including FMCSA 
and TSA research and development efforts for commercial vehicle 
security technologies. Both FMCSA and TSA have also completed pilot 
studies of tracking systems for commercial trucks carrying hazardous 
materials. For example, FMCSA completed a study of existing 
technologies in December 2004 evaluating wireless communications 
systems, including global positioning satellite tracking and other 
technologies that allow companies to monitor the location of their 
trucks and buses. TSA is testing tracking and identification systems, 
theft detection and alert systems, motor vehicle disabling systems, and 
systems to prevent unauthorized operation of trucks and unauthorized 
access to their cargos. The 9/11 Commission Act requires that DHS 
provide a report to Congress by August 2008, that includes, among other 
things, assessments of (1) the economic impact that security upgrades 
of trucks, truck equipment, or truck facilities may have on the 
trucking industry, including independent owner-operators; (2) ongoing 
research by public and private entities and the need for additional 
research on truck security; and (3) the current status of secure truck 
parking.[Footnote 60] TSA officials stated that they are working on 
developing this report but have not completed it. The 9/11 Commission 
Act also required that DHS develop a tracking program for motor carrier 
shipments of hazardous materials by February 2008.[Footnote 61] TSA 
officials reported that they worked with DOT and implemented a program 
to facilitate truck tracking in January 2008. However, TSA stated that 
while the 9/11 Commission Act mandated the tracking program and 
authorized $21 million over 3 years for its activities, it was never 
implemented because no funds were appropriated for the program. 

The 9/11 Commission Act also had a number of mandates regarding the 
security of over-the-road buses, including that DHS issue regulations 
by February 2008 requiring all over-the-road bus operators to develop 
and implement security training programs for frontline employees, and 
that DHS establish a security exercise program for over-the-road bus 
transportation.[Footnote 62] The 9/11 Commission Act further requires 
that DHS issue regulations by February 2009 requiring high-risk over- 
the-road bus operators to conduct vulnerability assessments and develop 
and implement security plans.[Footnote 63] TSA officials stated that 
they were preparing a Notice of Proposed Rulemaking that, if finalized, 
would require high-risk, over-the-road bus operators to conduct 
vulnerability assessments, and develop security plans and training 
plans.[Footnote 64] 

State Actions: 

States are responsible for securing highway infrastructure, including 
highways, bridges, and tunnels, and for ensuring the security and 
safety of these roadways. State officials work on security issues 
within their individual states and with other states through several 
national associations. State transportation officials--through the 
American Association of State Highway and Transportation Officials 
(AASHTO)--and state law enforcement officials--through the Commercial 
Vehicle Safety Alliance (CVSA)--have worked collectively to strengthen 
the security of commercial vehicles and highway infrastructure through 
various expert committees and the implementation of joint initiatives 
with TSA and DOT. AASHTO formed a Special Committee on Transportation 
Security that has sponsored highway and commercial vehicle security 
research at the National Academies of Science. AASHTO also conducts 
surveys of state DOT security efforts, priorities, and identified 
needs. AASHTO's August 2007 survey found that many state departments of 
transportation still needed basic training on integrating homeland 
security considerations in the planning process; detecting, deterring, 
and mitigating homeland security threats; and assessing transportation 
network homeland security vulnerabilities and risks. CVSA's state law 
enforcement members have also organized committees on Transportation 
Security, Information Systems, Intelligent Transportation Systems, 
Hazardous Materials, Passenger Carrier, and Training to pool and 
provide expertise to promote best practices, new programs, and the 
consistent application of regulations. For example, the purpose of the 
CVSA's Transportation Security Committee is to enhance homeland 
security by providing a forum to identify, develop, implement, and 
evaluate education, enforcement, and information-sharing strategies for 
enhancing commercial motor vehicle security. CVSA's Program Initiatives 
committee originated the idea of conducting a CSR pilot in 
Missouri.[Footnote 65] 

We interviewed transportation, law enforcement, and homeland security 
officials responsible for commercial vehicle security from eight states 
to determine the nature and extent of their security efforts. These 
officials stated that they generally focused on law enforcement, 
protection of highway infrastructure, conducting inspections of 
commercial vehicles, and monitoring threats of all kinds.[Footnote 66] 
Officials in each state stated that they understood the major 
transportation security risks in their state. For example, officials 
from one state that has numerous chemical plants expressed particular 
concern about the shipment of these chemicals, while officials from 
another state with extensive military bases expressed concern about 
shipments of nuclear weapons and waste. Officials from yet another 
state with numerous explosives plants were more concerned about the 
transportation of explosives. State and local authorities have also 
created 58 fusion centers around the country to blend relevant law 
enforcement and intelligence information analysis and coordinate 
federal, state, and local security measures in order to reduce threats 
in local communities. DHS analysts work with state and local 
authorities at fusion centers to facilitate the two-way flow of 
information on all types of hazards. DHS has provided staff and more 
than $254 million to state and local governments to support these 
centers and facilitate the two-way flow of information between DHS and 
the states.[Footnote 67] Although states have a number of security 
efforts involving the commercial vehicle sector, none of the state 
officials whom we interviewed (with the exception of those from 
Missouri) reported conducting formal vulnerability assessments of the 
commercial vehicle sector in their states. 

Private Sector Security Actions: 

Industry associations we interviewed were actively assisting their 
members in strengthening the security of the commercial vehicle sector. 
We met with 12 of the industry associations representing the commercial 
vehicle industry, including trucking, motor coaches, shipping, and 
unions, 9 of which were members of TSA's SCC. TSA relies on the SCC and 
its industry association members to facilitate communications between 
the agency and the commercial vehicle industry, and to assist in the 
development of sector strategies, plans, and policies. Eight of these 
industry associations reported that they regularly provided federal 
officials with their industry's perspective on proposed regulations and 
legislation. Additionally, 8 of the 12 associations reported that they 
were proactively providing security guidance to their members, which 
included guidance on security best practices, security awareness, and 
security self-assessments. In addition, about a third of the 
associations we reviewed reported providing training, security 
bulletins, and 24-hour hotlines for their members. TSA supports several 
of these industry initiatives, including working with trade 
associations to develop and distribute security brochures for their 
members. 

As discussed earlier in this report, the Missouri CSR Pilot evaluation 
showed that firms carrying hazardous materials were complying with 
regulations and implementing more security measures to mitigate their 
risks than other commercial vehicle firms.[Footnote 68] In contrast, 
the study further found that truck companies not transporting hazardous 
materials were implementing few of TSA's best security practices. 
During our site visits to 20 truck and 6 bus companies, ranging in size 
from the nation's largest commercial vehicle company with 27,453 trucks 
to an owner-operator with a single truck, we found that most had some 
form of personnel security procedures and background checks in place, 
as well as terminal security, communications systems, and truck 
tracking systems. Overall, the types of security practices among the 
commercial trucking companies we visited were similar, but the 
prevalence and sophistication of these practices varied. The range of 
security practices that companies were using included requiring drivers 
to lock doors and inspect cargo; cargo seals; driver background checks; 
vehicle tracking technology; terminal fencing, cameras, and gates; 
access controls, such as employee identification badges, sign-in and 
sign-out sheets, or electronic key cards; en route security measures; 
and driver training. Large corporations and small one-truck owner- 
operators generally used differently scaled security approaches to the 
same problem. For example, while a cell phone can suffice for the 
communications needs of a small operator, a large company may invest in 
integrated communications and tracking technologies. Conversely, where 
a large company may have a well-lit, gated terminal monitored by 
security cameras and guards, a small operator may lock the door of the 
vehicle and have a watch dog on the premises. In another example, 
small, independent owner-operator firms may rely solely on emergency 
responders such as 911 and state patrol hotlines, while larger firms 
may have dispatchers and in-house security specialists on duty 24 hours 
a day. 

TSA Uses Performance Measures to Monitor Its Efforts in Securing 
Commercial Vehicles, but Lacks Effectiveness Measures for Key Security 
Programs: 

TSA has begun developing measures that gauge the completion of its 
program activities, but could improve its efforts by collecting data 
that would measure the effectiveness of its programs in strengthening 
commercial vehicle security. Performance measures are indicators, 
statistics, or metrics used to gauge program performance.[Footnote 69] 
Output measures summarize the direct products and services delivered by 
a program, while outcome measures try to gauge the results of products 
and services delivered by a program.[Footnote 70] TSA has begun 
developing and using performance measures to assess the progress of 
commercial vehicle security programs, but does not have outcome data to 
monitor how effectively its programs are achieving their intended 
purpose, as suggested by GPRA. The TSSP also states that performance 
measures of strategic goals and objectives should be outcome-based, but 
notes that interim output measures may be used during the early years 
of the program while baseline data on the program's performance are 
being acquired. The TSSP also requires that TSA form a Performance 
Measurement Joint Working Group to recommend the appropriate mix of 
output and outcome measures for agency programs, outcome monitoring 
techniques, and standardize measures across transportation sectors. As 
of August 2008, TSA had formed the transportation sectorwide working 
group, and according to officials the group was instrumental in 
developing and reporting on the transportation sector's core, 
programmatic, and partnership metrics required by the NIPP. However, 
the joint measurement group for the highway and motor carrier sector 
had not been formed to develop outcome measures for commercial vehicle 
security programs. 

Currently, TSA HMC collects performance data on its own programs, while 
other commercial vehicle security programs are monitored by other DHS 
or DOT components. At our suggestion, TSA officials stated they plan to 
work out an agreement with DOT to receive performance measurement data 
for DOT security programs, stating that performance data for these 
programs are important and necessary for an overall view of the impact 
of federal security programs. TSA officials stated they would request 
that TSA and DOT share performance measurement data for commercial 
security programs as the DHS and DOT MOU is updated. The annex to 
improve coordination and data sharing between TSA and PHMSA was signed 
in October 2008. Table 2 summarizes the various federal commercial 
vehicle security programs and the agency responsible for administering 
the program and measuring its progress.

[End of table] 

TSA's HMC established output measures for all five of its commercial 
vehicle security programs to assist the agency in gauging the 
performance of these programs. As of September 30, 2008, TSA reported 
that it had completed: 

* 100 percent of the target goal of 24 CSRs per year, 

* 100 percent of the SAI goal of developing voluntary guidelines to 
reduce risk and enhance the security of high-risk hazardous materials, 

* 52 percent of hazardous materials driver's license endorsement 
security threat assessment background checks, and: 

* 100 percent of the work in developing a pilot Truck Tracking Center. 

Output-based measures can be useful to TSA for program management 
purposes, as they can identify whether programs are producing a desired 
level of output and meeting established milestones. However, they do 
not measure TSA's success in achieving the ultimate goal of enhancing 
the security of the commercial vehicle sector. For example, while TSA 
tracks the number of CSRs completed by its staff or as part of the 
Missouri CSR program, it has not attempted to measure the effect these 
programs are having. Missouri officials have suggested that a sample of 
firms that participated in the CSR program should be revisited to 
determine the extent to which their security-related practices improved 
after completing a CSR. Such information could provide TSA with a 
measure of the effectiveness of its key commercial vehicle security 
program. In January 2009, TSA stated that it was planning to conduct 
baseline and follow-on CSRs on hazardous material transporters to 
measure changes in preparedness. 

We recognize that TSA faces challenges in developing outcome measures 
to monitor and evaluate the effectiveness of its security programs that 
rely on the participation of many public and private entities. In 
addition, it can be difficult to develop performance measures to gauge 
the impact of a program in deterring terrorism. Nonetheless, outcome 
measures of programs designed to mitigate vulnerabilities and 
consequences are possible. For example, the domain awareness of drivers 
could be measured both before and after participating in the Trucking 
Security Grant program. 

Furthermore, as we have previously reported, a focus on results as 
envisioned by GPRA means that federal agencies are to look beyond their 
organizational boundaries and coordinate with other agencies to ensure 
that their efforts are aligned. The planning processes under GPRA 
provide a means for agencies to ensure that their goals for 
crosscutting programs complement those of other agencies; program 
strategies are mutually reinforcing; and, as appropriate, common or 
complementary performance measures are used. High-performing 
organizations use their performance management systems to strengthen 
accountability for results, specifically by placing greater emphasis on 
fostering the necessary collaboration both within and across 
organizational boundaries to achieve results.[Footnote 71] 

TSA officials agreed that opportunities exist to develop outcome 
performance measures for the agency's commercial vehicle security 
programs, and stated that they would like to do so in the future. We 
previously reported that DHS often lacked the performance information 
to determine where to target program resources to improve performance, 
but was taking steps to strengthen their performance measures.[Footnote 
72] GAO is currently working with DHS, including TSA, to provide input 
on the department's performance measurement efforts based on our work 
at the department. 

TSA Has Strengthened Efforts to Coordinate with Federal, State, and 
Industry Stakeholders Regarding the Security of the Commercial Vehicle 
Sector, but Further Actions Can Enhance Coordination: 

While TSA has taken actions to improve coordination with federal, 
state, and industry stakeholders to strengthen commercial vehicle 
security, more can be done to ensure that these coordination efforts 
enhance security for the sector. Leading practices for collaborating 
agencies that we have previously identified offer suggestions for 
strengthening coordination with other public and private sector 
stakeholders. These key practices include, for example, defining common 
outcomes and complementary strategies; agreeing on roles and 
responsibilities; leveraging stakeholder resources; and developing 
mechanisms to monitor, evaluate, and report on the results of the 
collaborative effort.[Footnote 73] DHS and DOT signed an agreement that 
established broad areas of responsibility regarding the security of the 
transportation network, as we previously recommended.[Footnote 74] TSA 
supported the creation of an intergovernmental and industry council to 
gather feedback and input about security planning, among other efforts. 
TSA has made limited progress in leveraging FMCSA resources and 
resolving potentially duplicative security inspections, but in October 
2008 signed an agreement to enhance coordination with FMCSA. Although 
TSA has successfully leveraged resources in the State of Missouri to 
conduct CSR vulnerability assessments, it has made limited progress in 
coordinating the expansion of CSRs to other states. Some state and 
industry officials we interviewed expressed concerns about TSA's 
coordination and communication with the sector on developing a security 
strategy, and fully defining roles and responsibilities for the 
industry. Since many owner operators are hard to contact, some 
suggested that TSA enhance its Web site to better communicate directly 
with the industry's many small operators. Moreover, the Missouri CSR 
pilot evaluation similarly suggested that TSA consider developing a two-
way Web portal to allow firms to fill out CSR questionnaires. TSA 
officials stated that they have taken steps to interact with industry 
regarding the security of the sector, and have also leveraged industry 
expertise to strengthen security. However, TSA has not developed a 
means to monitor the effectiveness of its coordination actions with 
this very large and diverse sector. Without enhanced coordination, TSA 
will have difficulty expanding its vulnerability assessments to other 
states. 

DHS and DOT Have Entered into Formal Agreements and Taken Other Actions 
to Enhance Coordination: 

DHS and DOT have taken actions toward coordinating their efforts to 
strengthen commercial vehicle security. In September 2004, DHS and DOT 
signed a MOU that established broad areas of responsibility for each 
department related to the security of the transportation sector, and 
specified roles and responsibilities to strengthen their cooperation 
and coordination. For instance, under the MOU, DOT recognized that DHS 
has primary responsibility for transportation security while it plays a 
supporting role, providing technical assistance and supporting DHS in 
the implementation of its security policies as allowed by DOT statutory 
authorities. Furthermore, the MOU states that DHS is to establish 
national transportation security performance goals and, to the extent 
practicable, appropriate security measures for each transportation 
sector to achieve an integrated national transportation security 
system. The MOU responds to our previous work which emphasized the need 
for greater coordination between DOT and DHS on transportation security 
efforts and recommended that the two departments establish an MOU to, 
among other things, delineate the roles, responsibilities, and funding 
authorities of the each department.[Footnote 75] 

In August 2006, TSA and PHMSA signed an annex to the DHS and DOT MOU, 
identifying their respective roles and responsibilities related to 
research and development, training, outreach, risk assessments, and 
technical assistance involving hazardous materials transportation 
security. According to this agreement, the parties commit themselves to 
seeking consensus on measures to reduce risk and minimize consequences 
of emergencies, sharing information that may concern the interests of 
the other party, and coordinating the development of transportation 
security-related guidelines. The annex further specified that TSA and 
PHMSA will, among other things: 

* base security planning on risk, seek consensus concerning measures to 
reduce risk, and coordinate in the development of standards, 
regulations, guidelines, and directives; 

* coordinate on observations and recommended security measures; 

* explore opportunities for collaboration in inspection and enforcement 
activities; and: 

* share information during an emergency. 

Consistent with this agreement, PHMSA and TSA worked together to 
develop recommended security measures for hazardous materials carriers. 
As we have previously identified, an effectively implemented leveraging 
of stakeholder resources is a key practice for enhancing 
collaboration.[Footnote 76] According to leading practices for 
collaborating agencies, such parties bring different levels of 
resources and capacities to the collective effort; therefore, the 
parties should identify the types of resources necessary to initiate or 
sustain their collective effort, as well as assess each party's 
relative strengths and limitations. In 2003, working with TSA, PHMSA 
established a set of security plan requirements for hazardous materials 
carriers that addressed the elements of en route security, unauthorized 
access, and personnel security. TSA later expanded upon PHMSA's 
requirements and, in consultation with PHMSA, drafted a set of 
voluntary security standards, called Security Action Items (SAIs), 
specifying the level of security suggested for each type of security- 
sensitive hazardous materials, or hazardous materials transported by 
motor vehicles whose potential consequences from an act of terrorism 
may result in detrimental effects to the economy, communities, critical 
infrastructure, or individuals of the United States. TSA reported that 
these SAIs were finalized in June 2008 and distributed to stakeholders. 
TSA further worked with PHMSA to develop guidance on security-sensitive 
hazardous materials. 

TSA also established a GCC in April 2006 to monitor and evaluate the 
results of federal highway and motor carrier security programs, as 
required by the NIPP. We previously identified the need for 
collaborating agencies to create a mechanism to monitor and evaluate 
their efforts and to assist them in identifying areas for improvement. 
If implemented effectively, reporting on these collaborative activities 
can help key decision makers obtain feedback for improving both policy 
and operational effectiveness. The GCC consists of federal agencies and 
associations representing state and local transportation and law 
enforcement officials, and motor vehicle administrators with 
responsibilities directly related to commercial vehicle security. (For 
a complete list of GCC members, see app. VI). The GCC is intended to 
coordinate strategies, activities, and communications among its member 
entities, and establish policies, guidelines, metrics, and performance 
criteria.[Footnote 77] The highway sector GCC meets approximately once 
monthly, and both FMCSA and PHMSA officials expressed general 
satisfaction with the GCC.[Footnote 78] 

DHS and DOT Can Strengthen Efforts to Leverage Resources and Avoid 
Duplication of Effort: 

Although DHS and DOT have established agreements and developed 
complementary strategies to strengthen security of the commercial 
vehicles sector, gaps remain that hamper their ability to more 
effectively coordinate their efforts. Specifically, the two departments 
have not fully agreed on a strategy to leverage resources and eliminate 
potential duplication of effort and to share inspection information for 
monitoring security programs. 

TSA and FMCSA have shared roles and responsibilities regarding the 
enhancement of commercial vehicle security, but have different 
capabilities and resources. TSA HMC has a staff allocation of 19 FTEs. 
These staff are responsible for all aspects of commercial vehicle and 
highway infrastructure security including developing best practices, 
conducting risk assessments, and establishing policy. HMC is also 
responsible for school bus security. FMCSA has 650 to 700 staff 
deployed in the field nationwide to conduct inspections, enforce 
Federal Motor Carrier safety regulations and hazardous materials 
transportation safety and security regulations, and coordinate with 
state safety inspectors. Moreover, TSA and FMCSA have similar 
inspection programs, both of which are currently focused on hazardous 
materials transportation. As discussed earlier in this report, TSA 
operates the CSR program designed to review the security efforts and 
vulnerabilities of all types of commercial vehicle firms, and FMCSA 
conducts security compliance inspections (SCRs) of hazardous materials 
carriers.[Footnote 79] 

The 9/11 Commission Act requires that DOT consult with DHS to limit, to 
the extent practicable, duplicative reviews of the hazardous materials 
security plans. [Footnote 80] TSA and FMCSA officials stated that they 
have discussed how best to leverage FMCSA's ongoing inspections 
programs and the feasibility of merging the two inspection programs. 
Officials reported that their interactions to date have focused on how 
best to take advantage of the similarities between these programs to 
more efficiently and effectively use agency resources, reduce 
potentially duplicative efforts, and minimize the burden on the 
industry. TSA officials stated that one obstacle to merging the two 
programs is that hazardous materials transportation companies are 
required to participate in FMCSA's SCRs because they are subject to 
DOT's hazardous materials regulations, while TSA's CSRs are a voluntary 
effort. However, both agencies' programs share voluntary and mandatory 
aspects. For example, along with SCRs, FMCSA also conducts Security 
Sensitivity Visits, which as discussed earlier in this report are 
voluntary, educational security reviews of firms carrying small amounts 
of hazardous materials. Moreover, TSA's Missouri pilot successfully 
demonstrated that voluntary security reviews could be appended to 
mandatory safety reviews, and that state safety inspectors could be 
trained to conduct CSR security reviews. TSA officials further stated 
that the agency's CSR reviews include a detailed assessment of the 
adequacy of security plans, whereas FMCSA reviews are intended to 
ensure a firm's compliance with its written security plan, but are not 
an assessment of its adequacy. Another obstacle, according to TSA 
officials, is associated with how the two agencies view their missions 
and resource sharing. TSA believes utilizing FMCSA resources, 
infrastructure, and databases may be cost effective. However, DOT 
officials told us that the primary role of FMCSA's inspectors is safety 
rather than security. One industry association we interviewed stated 
that they were working with FMCSA and TSA to merge their commercial 
vehicle security programs because association officials believed it 
would reduce duplication and be more efficient for both government and 
industry. By leveraging resources with FMCSA, TSA may be able to 
address other priorities, such as conducting additional vulnerability 
assessments, improving security mitigation programs beyond the 
hazardous materials sector, and addressing highway infrastructure 
protection. 

TSA and FMCSA also do not have a process in place to share information 
important to monitoring the results of security programs, consistent 
with leading practices for collaborating agencies. For example, the 
agencies are not comparing and contrasting their findings from 
commercial vehicle security inspections. Both TSA and FMCSA concurred 
that they could benefit from better sharing of information and have 
discussed developing a unified database for storing and sharing 
information on CSR and SCRs. Without a process in place to share 
information on the results of their security programs, TSA will not 
have a complete picture of the effectiveness of federal programs to 
secure the sector. FMCSA also maintains other data and information that 
could potentially be useful to TSA in its effort to understand and 
analyze the commercial trucking and motor coach industries. For 
example, the Missouri CSR program selected carriers with particularly 
bad safety records for review, but TSA does not have general, direct 
access to these data.[Footnote 81] FMCSA also maintains the Motor 
Carrier Management Information System (MCMIS) database of all 
interstate, and some intrastate companies, and all carriers of 
hazardous materials. Access to MCMIS data could assist TSA in 
addressing the NIPP requirement that the agency develop an inventory of 
assets as a basis for conducting vulnerability and consequence 
assessments. In addition, as TSA expands its CSRs of hazardous 
materials transporters, DOT may benefit from knowing which firms TSA 
has reviewed to avoid duplication of effort. 

Although TSA and PHMSA have signed an annex detailing how they will 
collaborate, TSA and FMCSA officials stated that they did not establish 
a similar agreement because the agencies coordinated with each other 
well, and an annex was not necessary. However, with enactment of the 9/ 
11 Commission Act, TSA and FMCSA were required to complete an annex by 
August 2008 that defined the processes that will be used to promote 
communications and efficiency, and avoid duplication of 
effort.[Footnote 82] An annex to the MOU between TSA and FMCSA might 
help reduce possible duplication of effort in inspection programs, as 
well as facilitate the development of a process for sharing data to 
monitor program results. TSA and FMCSA officials signed an annex to the 
MOU in October 2008. 

The TSSP also requires that the GCC and the SCC create several joint 
working groups for research and development, performance measurement, 
intelligence, and risk.[Footnote 83] These groups are to improve 
coordination and prioritization of TSA's research and development 
efforts, address the inherent difficulties in measuring and assessing 
the performance of security mitigation programs, develop sector- 
specific metrics, and coordinate and integrate intelligence efforts. 
However, the creation of these committees has been delayed, according 
to TSA officials. Without promptly developing joint working groups, TSA 
increases the risk that collaborative work and progress in these areas 
will be delayed. TSA officials stated that as of September 2008, the 
Joint Working Groups for Highway and Motor Carrier had not been 
officially approved. 

TSA Has Increased Vulnerability Assessments by Collaborating with the 
State of Missouri, but Has Not Developed a Plan to Expand the Approach 
to the Other States: 

TSA has leveraged resources to enhance its capabilities to perform CSR 
vulnerability assessments through collaboration with the state of 
Missouri, and recently reached agreements with Michigan and Colorado to 
conduct CSRs, but has faced challenges in expanding this collaborative 
effort to other states. These state coordination challenges have the 
potential to significantly delay progress in expanding vulnerability 
assessments to other states. TSA officials stated that it was 
continuing to explore opportunities to expand the CSR program from 
Missouri to other states, and to leverage state field inspector and law 
enforcement resources. 

TSA also does not have a direct mechanism for coordinating its strategy 
with the states related to commercial vehicle security planning, and 
some state officials we spoke to expressed dissatisfaction with TSA's 
coordination efforts. The agency relies on several GCC-member 
associations that represent state and local transportation and law 
enforcement officials to coordinate with states. However, all of these 
state GCC stakeholders identified concerns about the adequacy of TSA 
coordination efforts. For example, CVSA, which represents state law 
enforcement officials at the GCC, stated that the GCC is not an 
effective means of communication and coordination, and that direct 
communication with the states was minimal. As a result, CVSA 
transportation security officials stated that they were not fully 
informed about TSA's risk management strategy. CVSA officials further 
stated, in September 2008, that while coordination with TSA had 
improved after TSA's staffing stabilized, they continued to be 
concerned that the federal government was more engaged in helping 
states ensure safety rather than security. They also questioned whether 
TSA had dedicated sufficient resources to commercial vehicle security, 
or had the expertise to lead federal efforts to expand vulnerability 
assessments nationwide. CVSA officials stated that since DOT had the 
resources but not the authority to oversee commercial vehicle security, 
it is difficult for either agency to assist the states. 

Another key association, AASHTO, which represents state transportation 
officials at the GCC, stated that state security planners are given 
insufficient attention and information by TSA and other DHS components 
relating to security. Specifically, AASHTO officials stated that TSA 
had not communicated its strategy or initiatives to secure commercial 
vehicles, and that while AASHTO has tried to discuss what role the 
states play in transportation security with DHS and TSA, neither has 
been responsive in providing fully defined roles.[Footnote 84] Several 
officials we spoke with during our interviews with state DOTs also 
expressed concerns regarding whether the GCC is a sufficient mechanism 
for TSA to coordinate with the 50 states and were also critical of 
TSA's leadership and communication related to commercial vehicle 
security. For example, one state noted that TSA's slow pace in 
providing guidance was causing it to delay the implementation of its 
programs for fear such programs would conflict with TSA initiatives. 
TSA officials stated that the agency had coordinated with states to the 
extent possible with available resources--having one staff member 
responsible for federal, state, and industry coordination. 

TSA Has Worked to Strengthen Partnerships with the Commercial Vehicle 
Industry, but Stakeholders Identified Coordination Challenges, and the 
Effects of Existing Coordination Efforts Are Unknown: 

TSA has made progress in involving industry in their strategy for 
strengthening commercial vehicle security by supporting the formation 
of an industry stakeholder council and through ongoing outreach efforts 
and meetings with industry officials. However, as discussed earlier in 
this report, industry officials we interviewed stated that they 
generally desired greater communication with TSA. More specifically, 
the officials noted that they did not fully understand TSA's strategy 
for securing the commercial vehicle sector, or what roles and 
responsibilities the agency expected from industry. Additionally, TSA 
does not have any measures of the effectiveness of its efforts to 
coordinate with its many stakeholders, which limits its ability to 
determine whether its ongoing efforts to collaborate are appropriate 
and adequate for this very large and diverse transportation sector. 
Without strengthening communication and coordination with industry, TSA 
will not be able to fully leverage the resources of its stakeholders. 
Four of the leading practices for collaborating agencies we previously 
identified to help improve coordination among federal agencies could 
also be applied to improve federal collaboration with industry 
stakeholders--defining a common outcome and complementary strategies, 
agreeing on roles and responsibilities, leveraging stakeholder 
resources, and monitoring results. 

TSA coordinates with the commercial vehicles sector through an industry 
council and industry associations. To (1) overcome the challenge of 
working in partnership with such a large and diverse group of 
stakeholders, (2) understand the current security practices of these 
industries, and (3) gather industry input and feedback, TSA supported 
the creation of the Highway and Motor Carrier Sector Coordinating 
Council (SCC) in June 2006. The SCC represents three private industry 
groups: highway passenger and school bus carriers, highway freight 
carriers, and highway infrastructure owners and builders, and 
facilitates communications within the industry and between the industry 
and TSA. According to members, its purpose is to represent a broad 
cross-section of the industry, and there is no limit on the number of 
organizations that can participate. As of September 2008, the SCC had 
convened eight times since its first meeting in August 2006, and holds 
separate meetings to address issues requiring a quick response. Apart 
from the SCC, TSA has also collaborated with several industry trade 
associations to develop and distribute security brochures and guides 
for their membership. For example, TSA assisted the Truck Rental and 
Leasing Association in developing its Security Awareness and Self- 
Assessment Guide. 

Although TSA has made progress in coordinating with industry 
stakeholders, challenges remain. Specifically, SCC officials stated 
that the council was dissatisfied with TSA's level of coordination with 
the SCC on the development of a strategy for enhancing commercial 
vehicle security. For example, the SCC leadership stated that the SCC 
was excluded from key stages of drafting revisions to the initial TSSP 
annex. The TSSP states that its initial goals and objectives would be 
developed by TSA, and be informed by comments and suggestions from the 
SCC, and going forward the TSSP annex states that the GCC and SCC are 
to prepare future revisions of the TSA strategy in the TSSP annex. SCC 
officials said that TSA did not consult with them regarding the 
development of key strategic objectives, known as Strategic Risk 
Objectives, or the Highway and Motor Carrier Annual Report regarding 
progress made and goals for the next year. These officials stated that 
overall coordination was better on trucking issues than for motor 
coach. Furthermore, industry and company officials we interviewed also 
expressed concerns about TSA's coordination efforts regarding its 
strategy Specifically, officials from 9 of the 12 industry associations 
and 20 of the 26 truck and bus companies we interviewed, some of whom 
were also members of the SCC, stated that they were not familiar with 
TSA's strategy and/or ongoing efforts to secure the commercial vehicle 
sector, and that TSA could strengthen its coordination with industry. 
Officials stated that in some cases, a lack of information led industry 
associations to hesitate in implementing security actions and 
dedicating resources to additional security measures that TSA may 
determine are not necessary or identify other required measures that 
must be implemented instead. Finally, SCC officials stated that TSA had 
not explicitly defined roles and responsibilities for the committee, 
its members, or the industry. Several industry association 
representatives also expressed similar confusion over their 
responsibilities and roles in securing the commercial vehicle sector. 
TSA officials stated that the SCC was not consulted in the development 
of the Highway and Motorcarrier Annex because TSA did not have enough 
time to include them. However, the SCC disagreed stating that TSA had 
received an extension on when the annex was due. TSA officials also 
said that they were not surprised by the uncertainty about their 
strategy for securing the sector because TSA's focus has been largely 
on developing security programs rather than communicating its security 
strategy to industry. TSA officials stated that going forward, they 
will work with the SCC as it revises the Highway and Motor Carrier 
Annex to the TSSP. The SCC leadership stated that during the revision 
to the latest HMC annual report, TSA was much more open to SCC's input. 

Our previous work on effective interagency collaboration has 
demonstrated that to achieve a common outcome, collaborating agencies 
need to establish strategies that work in concert with those of their 
partners or are joint in nature.[Footnote 85] Our prior work has 
further shown that collaboration can be enhanced when parties work 
together to define and agree on their respective roles and 
responsibilities, including how the collaborative effort will be led. 
Responsibility for securing the commercial vehicle sector involves 
collaboration between governmental and nongovernmental entities that 
typically have not worked together before on these issues. A fully 
defined outcome and strategy facilitates overcoming significant 
differences in organizational missions, cultures, and established ways 
of doing business. Without defining a common outcome and strategy, 
individual organizations increase the risk of developing strategies for 
securing the commercial vehicles industry that differ and conflict 
rather than help organizations better align their activities and 
resources to accomplish a common outcome. Fully defining and clarifying 
respective roles and responsibilities will be important to ensure that 
TSA and industry understand who will do what regarding securing the 
commercial vehicle sector, and help to reconcile differing perceptions 
of leadership that exist among stakeholders. 

SCC representatives stated that TSA has not maintained active 
communication with the committee, resulting in missed opportunities to 
take advantage of their potential contributions, including leveraging 
of their expertise and resources. TSA officials stated that given the 
SCC's recent establishment, it may be too soon to fairly assess the 
effectiveness of their interactions with the council. Most companies we 
spoke with stated that they rarely heard from TSA if at all, although 
they were generally much more familiar with FMCSA with whom they have 
worked for years. Some company officials suggested that TSA develop a 
direct means of communicating with the industry, such as through e-mail 
or a robust Web page. The Missouri Pilot Program Evaluation Report also 
recommended that TSA develop a Web portal to improve coordination and 
communication with the industry. The lack of communications and 
coordination could limit the effectiveness of standards and measures 
meant to enhance the security of commercial vehicles. 

TSA officials stated that the agency has conducted outreach with 
private industry to, among other things, coordinate its overall 
strategy and roles and responsibilities. According to officials, TSA 
has made numerous resources available to private industry stakeholders 
through the Homeland Security Information Network and more recently 
through TSA's Highway and Motor Carrier Web site link.[Footnote 86] 
Additionally, TSA reported that officials from the HMC are continually 
attending association conferences and workshops to educate and share 
TSA's strategy, goals, and policies. To further improve communications, 
TSA reported that it has conducted 14 monthly conference calls since 
2007 with attendees varying from 10 to 20 stakeholder participants. TSA 
officials stated that, while minor issues regarding specific lines of 
communication may have existed, in their opinion, the general level of 
coordination with the industry has been successful and that they were 
unaware of any significant private sector stakeholder misunderstandings 
of the agency's security strategy, efforts, or their own roles and 
responsibilities. 

While TSA's actions should help strengthen coordination with the 
commercial vehicle industry, the extent of any effect of these efforts 
is unknown because, according to TSA officials, the agency has not 
developed an approach to evaluate the effectiveness of its coordination 
efforts. Specifically, TSA does not have measures of how coordination 
efforts such as its current Web site, its participation in conferences, 
its efforts to coordinate with states, the GCC, and SCC result in a 
better understanding of TSA strategy and definitions of roles and 
responsibilities within the commercial vehicle sector. We have 
previously reported that collaborative efforts can be enhanced and 
sustained when they include mechanisms for monitoring and evaluation to 
assist stakeholders in identifying areas for improvement.[Footnote 87] 
Without such an evaluation, TSA will be hindered in determining whether 
its ongoing efforts to collaborate with the commercial vehicle industry 
are appropriate and effective for enhancing the security of this very 
large and diverse transportation sector. 

Conclusions: 

The nature, size, and complexity of the nation's commercial vehicle 
sector highlights the need for federal and state governments and the 
private sector to work together to secure this transportation sector. 
The importance of the nation's commercial trucking and motor coach 
industries and concerns about their security, coupled with finite 
homeland security resources, underscores the need for TSA to employ a 
risk management approach to prioritize its security efforts so that an 
appropriate balance between costs and security is obtained. TSA has 
taken steps in implementing a risk management approach by assessing 
threats to and from the commercial vehicle sector, conducting some 
vulnerability assessments, and initiating the development of best 
practices to secure the sector. Despite these achievements, much work 
remains to fully address the security risks of commercial trucks and 
motor coaches, and to ensure that this information is used to inform 
TSA's security strategy. TSA has not yet completed annual threat 
assessments with estimations of the likelihood of various threats or 
tactics, nor established a plan and a time frame for completing 
vulnerability assessments of the commercial vehicle industry and its 
diverse sectors and firms, to include considering the recommendations 
of the Missouri Pilot Program Evaluation. TSA also has not developed a 
plan to conduct consequence assessments, or leveraged the consequence 
assessments of other sectors. Further, TSA has not determined the 
extent to which additional risk assessments are needed, or the 
resources needed to support these efforts. Although TSA is having 
threat scenarios conducted to inform a preliminary risk assessment of 
the industry, these assessments will likely provide limited information 
on what sectors or companies are most at risk, and what mitigation 
practices are currently in place, unless they are further supported by 
field-level risk assessments, such as CSRs, consistent with the TSSP. 
As a result of not having specific threat assessments or complete 
vulnerability and consequence assessments, the agency is limited in its 
ability to determine the most pressing security needs, and to use this 
information to guide its security strategy. While working to develop 
complete risk assessments, it is important that TSA assess and use 
available information as the basis for its interim decisions. For 
example, information currently available from existing threat, 
vulnerability, and consequence assessments suggest alternatives or 
additions to the agency's current focus on commercial vehicle transport 
of hazardous materials. TSA has recently begun the process of revising 
its strategy for 2009 and beyond; however, without completed risk 
assessments, its revised strategy may not be appropriately targeted. 
Until TSA completes assessments of this very large and highly diverse 
transportation sector, and uses this information to inform its security 
strategy, it will be limited in its ability to assure Congress that 
existing funds are being spent in the most efficient and effective 
manner. 

TSA has developed a range of programs to strengthen truck and bus 
security, but has not developed outcome measures to assess how 
effectively the programs have improved security. Without such 
performance measures, TSA cannot monitor and evaluate whether or not 
these programs are achieving results in enhancing commercial vehicle 
security, nor communicate this progress to industry stakeholders, 
Congress, policymakers, and taxpayers. 

With 50 states and over a million diverse industry stakeholders, 
securing commercial vehicles can pose considerable communication 
challenges and lead to confusion about roles and responsibilities. 
Ultimately, the security of the industry is maintained by the companies 
themselves, and if TSA is to secure the sector it must do so by working 
with the industry. Coordination and communications techniques that 
might work well in other transportation sectors may be insufficient for 
the larger, more complex commercial vehicle industry. TSA has taken 
steps to coordinate with government and industry stakeholders, and has 
had some noteworthy successes such as the Missouri CSR program. 
However, both industry and state officials we interviewed stated that 
more needed to be done to enhance federal leadership and better ensure 
that federal, state, and industry actions and investments designed to 
enhance security are properly focused and prioritized. TSA communicates 
with states primarily through associations of state law enforcement and 
transportation officials who participate in the GCC. However, 
opportunities exist for more effective coordination with states to 
expand the Missouri CSR to other states, and for TSA to leverage 
FMCSA's resources in conducting field inspections. TSA could address 
industry concerns about communication of its strategy, roles, and 
responsibilities, as well as better leverage industry expertise, by 
working more collaboratively with industry representatives and 
improving communication with the nation's many small owner-operators 
and midsized firms. In addition, because TSA does not monitor and 
measure the effectiveness of its coordination and communications 
efforts, it cannot be sure that it is addressing stakeholder concerns. 
By improving coordination with DOT, the states, and the industry, TSA 
could build a solid foundation for strengthening the security of the 
commercial vehicle sector. 

Recommendations for Executive Action: 

To assist the Transportation Security Administration in more fully 
evaluating, selecting, and implementing commercial vehicle security 
risk mitigation activities, and to help strengthen the security of 
commercial vehicles in the United States and leverage the knowledge and 
practices employed by key federal and nonfederal stakeholders, we 
recommend that the Assistant Secretary for the Transportation Security 
Administration take the following four actions: 

1. Establish a plan and a time frame for completing risk assessments of 
the commercial vehicle sector, and use this information to support 
future updates to the Transportation Sector Strategic Plan, to include 
conducting: 

* to the extent feasible, assessments that include information about 
the likelihood of a terrorist attack method on a particular asset, 
system, or network as required by the National Infrastructure 
Protection Plan; 

* a vulnerability assessment of the commercial vehicle sector, 
including: 

- assessing the scope and method of assessments required to gauge the 
sector's vulnerabilities; 

- considering the findings and recommendations of the Missouri pilot 
evaluation report to strengthen future Corporate Security Reviews; and: 

- enhancing direct coordination with state governments to expand the 
Transportation Security Administration's field inspection Corporate 
Security Review capacities; 

* consequence assessments of the commercial vehicle sector, or 
developing alternative strategies to assess potential consequences of 
attacks, such as coordinating with other Sector-Specific Agencies to 
leverage their consequence assessment efforts. 

2. In future updates to the Highway Infrastructure and Motor Carrier 
Annex to the Transportation Sector Security Plan, clarify the basis for 
the agency's security strategy of focusing on the transportation of 
hazardous materials, the relative risk of vehicle-borne improvised 
explosive devices to the sector, and, based on the relative risk of 
these threats, any risk mitigation activities to be implemented to 
address them. 

3. Develop outcome-based performance measures, to the extent possible, 
to assess the effectiveness of federal programs to enhance the security 
of the commercial vehicle sector. 

4. Establish a process to strengthen coordination with the commercial 
vehicle industry, including ensuring that the roles and 
responsibilities of industry and government are fully defined and 
clearly communicated; new approaches to enhance communication are 
considered; and monitoring and assessing the effectiveness of its 
coordination efforts. 

Agency Comments and Our Evaluation: 

We provided a draft of this report to DHS and DOT for review and 
comment. On January 15, 2009, DOT provided technical oral comments 
which we incorporated as appropriate. On February 6, 2009, we received 
written comments on the draft report from DHS, which are reproduced in 
full in appendix II. DHS concurred with our findings and 
recommendations and discussed efforts underway to address them. 

Regarding our recommendation that TSA establish a plan and a time frame 
for completing risk assessments of the commercial vehicle sector, and 
use this information to support future updates to the Transportation 
Sector Strategic Plan, DHS concurred and stated that TSA is actively 
conducting risk assessments of the major components of the commercial 
vehicle sector as required by the Implementing Recommendations of the 
9/11 Commission Act of 2007, and provided a timetable for completing 
these scenario-based risk assessments. According to TSA, these 
assessments will examine specific scenarios involving the commercial 
vehicle sector and will include information on the likelihood of a 
terrorist attack. We are pleased that TSA is beginning to conduct risk 
scenario assessments on various parts of the industry. However, we 
continue to believe that TSA needs to expand its use of threat 
likelihood estimates to the extent feasible. For example, we believe 
that TSA should address the feasibility of annual sector threat 
assessments including likelihood estimates. TSA also stated that it is 
planning to conduct annual field-level vulnerability assessment CSRs on 
a statistically valid sample of hazardous materials carriers. While we 
support these efforts, as we noted in the report carriers transporting 
hazardous materials represent only a small fraction of the industry. 
Therefore, we believe that TSA should also assess the scope and method 
of its vulnerability assessments for the entire sector, beginning with 
establishing the mix of expert scenarios and field assessments it deems 
most appropriate. In response to our recommendation that TSA conduct 
consequence assessments of the commercial vehicle sector or develop 
alternative strategies to assess potential consequences of attacks such 
as coordinating with other sector-specific agencies to leverage their 
consequence assessment efforts, TSA concurred and stated that it will 
examine consequence information based on the scenarios that have been 
developed, consult with public and private sector subject matter 
experts, and, when appropriate, consult with sector-specific agencies. 

DHS concurred with our recommendation that in future updates to the 
Highway Infrastructure and Motor Carrier Annex to the Transportation 
Sector Security Plan, they should clarify the basis for the agency's 
security strategy of focusing on the transportation of hazardous 
materials, the relative risk of vehicle-borne improvised explosive 
devices in the sector, and, based on the relative risk of these 
threats, any risk mitigation activities that should be implemented to 
address them. TSA stated that it intends to include risk-based 
clarification of the security strategies in future updates to the plan. 
According to TSA, for the past 2 years it has focused primarily on the 
transportation of hazardous materials. However, ongoing industry risk 
assessments and regulatory efforts may shift the current strategies, 
and communicating these strategies in the annex to all stakeholders 
will be critical to successful implementation of the plan. We believe 
that these efforts will help strengthen TSA's strategy for securing the 
sector. We further believe that it will be important for TSA to clarify 
the basis for its strategy and any shift in that strategy based on 
assessments of the relative risks. 

DHS concurred with our recommendation that TSA develop, to the extent 
possible, outcome-based performance measures to assess the 
effectiveness of federal programs to enhance the security of the 
commercial vehicle sector. DHS stated that TSA recognizes the 
importance of establishing outcome-based performance measures and 
described ongoing efforts. TSA stated that it intends to conduct annual 
CSRs on hazardous materials motor carriers to measure changes in 
industry security. While these activities will help TSA strengthen its 
ability to assess the effectiveness of ongoing security measures, we 
believe that the impact of TSA's programs on the progress of the rest 
of the commercial vehicle sector should be measured as well. 

DHS also concurred with our recommendation that TSA establish a process 
to strengthen coordination with the commercial vehicle industry, 
including ensuring that the roles and responsibilities of industry and 
government are fully defined and clearly communicated; new approaches 
to enhance communication are considered; and the effectiveness of its 
coordination efforts are monitored and assessed. DHS noted that TSA 
recognizes the importance of strong working relationships with both 
industry and other government agencies, and that through its work with 
coordination councils TSA has established a coordination process that 
continues to mature and develop. Finally, DHS noted that these 
coordination efforts are only 17 months old, hence performance 
measurement processes continue to be refined. We believe that given the 
size and complexity of the commercial vehicle sector, and the concerns 
expressed by various stakeholders, new approaches to enhance 
communication are important. As such, TSA should develop a process to 
monitor and assess the effectiveness of its coordination efforts. 

As agreed with your office, unless you publicly announce its contents 
earlier, we plan no further distribution of this report until 30 days 
from the date of this report. At that time, we will send copies of this 
report to the Secretary of Homeland Security, the Secretary of the 
Department of Transportation, and other interested parties. This report 
will also be available at no charge on our Web site at [hyperlink,

Appendix I: Objectives, Scope, and Methodology: 

The objectives of our review were to answer the following questions: 
(1) To what extent has TSA assessed the security risks associated with 
commercial vehicles and used this information to develop and implement 
a security strategy? (2) What security actions have key government and 
private sector stakeholders taken to mitigate identified risks to 
commercial vehicle security, and to what extent has TSA measured the 
effectiveness of its actions? (3) To what extent has TSA coordinated 
its strategy and efforts for securing commercial vehicles with other 
federal entities, states and private sector stakeholders? 

Federal Risk Assessment Activities: 

To review the extent to which the federal government has assessed 
security risks associated with commercial vehicles and used this 
information to develop and implement its security strategy, we analyzed 
DHS and DOT strategic and security planning documents such as the NIPP, 
the TSSP and its Highway and Motor Carrier Annex; performance documents 
including annual reports such as DHS's 2008 Performance Budget Overview 
and TSA HMC's Annual Reports and quarterly risk reduction reports; and 
risk assessment documentation--including assessments of threat, 
vulnerability, and standoff and evacuation distances. We interviewed 
officials from DHS National Protection and Programs Directorate; TSA's 
Office of Highway and Motor Carriers, Office of Risk Management and 
Strategic Planning, Office of Intelligence, and Office of Cargo Policy; 
DOT's Office of Intelligence and Security; PHMSA's Office of Hazardous 
Materials Safety; FMCSA's Office of Emergency Preparedness and 
Security; and DOT's Bureau of Transportation Statistics. 

To assess TSA's threat assessments, we analyzed its annual threat 
assessments and other intelligence products, and met with officials of 
TSA's Office of Intelligence. We also assessed documentation and 
interviewed TSA's HMC officials regarding the agency's use of the 
threat assessments for planning its vulnerability and consequence 
assessments. We also met with TSA's Risk Management Division and 
reviewed its use of estimates regarding the likelihood of certain types 
of specific threats for high-level NTSRA scenarios, and more systematic 
use of threat scenarios and likelihood estimates for the Aviation 
Domain Risk Assessment. To evaluate TSA's vulnerability assessments, we 
reviewed TSA's draft best practices, its vulnerability assessments 
known as Corporate Security Reviews (CSRs), and CSR questionnaires and 
reports. We also met with TSA HMC officials and interviewed officials 
from truck and bus companies that had undergone CSRs. To assess TSA's 
CSR pilot program, we attended two Missouri Pilot CSRs and analyzed the 
TSA-sponsored evaluation report of the CSR pilot. At the conclusion of 
the two CSRs we observed, we interviewed company officials about what 
they learned from the CSR, how germane it was to their security needs, 
and how appropriate TSA's suggested security measures were for their 
operating and business environment. We also met with Missouri state 
department of transportation and law enforcement officials and FMCSA 
field officers in Missouri to discuss their experiences with 
implementing the pilot and conducting CSRs. We also discussed the 
usefulness of the CSRs with officials from 12 leading industry trade 
associations representing the different sectors of the industry 
including, trucking companies, owner-operators, private truck 
companies, the bus industry, tank truck operators, hazardous materials 
shippers, rental and leasing firms, and unions. To review DOT's SCR 
inspections of hazardous material security plan implementation, we 
reviewed the SCR questionnaire, gathered data from agency Performance 
and Accountability Reports regarding their annual progress, and met 
with DOT FMCSA's Office of Emergency Preparedness and Security. We also 
analyzed FMCSA-sponsored vulnerability assessment of the U.S. motor 
coach Industry. We also reviewed the completeness of DOT MCMIS and BTS 
data on the population, or national inventory, of commercial vehicle 
firms, trucks, and drivers, because to determine industry 
vulnerabilities requires the development of a well-defined inventory or 
population of industry firms and assets. For more information, see 
appendix V. 

To evaluate TSA's consequence assessments, we analyzed DHS, DOD, and 
ATF data about standoff distances for VBIED explosions, tanker fuel 
truck fireballs, and TIH evacuation distances. We also interviewed 
officials from TSA's HMC and DHS's National Protection and Programs 
Directorate about their consequence assessment efforts. To explore the 
feasibility of TSA leveraging the consequence efforts of other sectors, 
we also reviewed the 17 Critical Infrastructure Sector Annual Reports 
for 2006 and 2007, and the Strategic Homeland Infrastructure Risk 
Assessment report which identifies the sectors most at risk from 
VBIEDs. 

To determine how, if at all, TSA used its risk assessments to inform 
its strategy for securing commercial vehicles, we reviewed its 
strategic plan, the TSSP annex, annual reports, and other related 
documents. We also interviewed HMC officials, and compared their 
actions to DHS risk management guidance in the NIPP and TSSP. The 
quality of TSA's CSR inspection data was previously assessed by the 
Missouri Pilot Evaluation. We reviewed the pilot evaluation and 
concurred with its conclusion that the Missouri sample was not 
representative of the commercial vehicle industry in Missouri or of the 
industry nationwide. To evaluate the extent to which TSA had a plan or 
a time frame to complete a comprehensive risk assessment of the 
commercial vehicle sector, we used standard practices in program and 
project management, which include developing a road map or a program 
plan to achieve programmatic results within a specified time frame or 
milestones.[Footnote 88] To evaluate TSA's progress in addressing the 
Missouri CSR Pilot evaluation, we used GAO's standards for internal 
controls in the federal government, which require that findings and 
deficiencies reported in audits and other reviews be promptly reviewed, 
resolved, and corrected within established time frames.[Footnote 89] 

Government and Private Sector Security Actions: 

To determine the actions the federal government and state and local 
governments have taken to mitigate commercial vehicle security risks, 
and the extent to which these actions are consistent with TSA's 
security strategy, we reviewed documentation and interviewed officials 
from TSA's Office of Highway and Motor Carrier and the Office of Cargo 
Policy; DOT PHMSA's Office of Hazardous Materials Safety; FMCSA's 
Office of Emergency Preparedness and Security; FHWA Transportation 
Security Office; and the FTA Office of Safety and Security. We also 
interviewed officials from eight states and conducted site visits to 
five.[Footnote 90] We selected the states in a nonprobability sample 
based on their characteristics, proximity to critical infrastructure 
and potential terrorist targets, such as large population centers, and 
the amount of hazardous materials (in tons) originating in the state. 
As a result, we cannot generalize the results to all states. However, 
we believe that observations obtained from these visits provided us 
with a greater understanding of the states' operations and 
perspectives. We gathered information from each regarding their actions 
to mitigate security risks, and any challenges they face in 
strengthening security. 

To identify industry actions taken to secure the commercial vehicle 
sector, we analyzed TSA's draft best practices and Security Action 
Items, and reviewed TSA CSR and FMCSA SCR and SSV inspection data. We 
also interviewed officials from 12 industry associations that represent 
trucking firms and truck drivers, truck manufacturers, truck rental and 
leasing companies, hazardous materials shippers, and intercity and tour 
bus companies to see what actions, if any, the association and its 
members were taking. We also reviewed security guidance industry trade 
associations had developed and provided to their members. To supplement 
what federal and industry associations told us and to observe industry 
operations firsthand, we also conducted site visits to 26 commercial 
truck and bus owner-operators. These companies were selected by a 
nonprobability sample based on: 

* size, using the number of vehicles (tractors, or power units for 
trucking companies, and buses for motor coach companies) as an 
indicator; 

* geographic location, noting the region's characteristics, proximity 
to critical infrastructure and potential terrorist targets such as 
large population centers, and the amount of hazardous materials (in 
tons) originating in the state; and: 

* type of operations, using the quantity of hazardous materials 
transported as an indicator for trucking companies. 

Because we used a nonprobability sample of owner-operators and states, 
the information we obtained from these interviews and visits cannot be 
generalized to all commercial vehicle companies. However, we believe 
that observations obtained from these visits provided us with a greater 
understanding of the industry's operations and perspectives. The 20 
trucking companies we visited included hazardous materials carriers, 
nonhazardous materials carriers, and carriers that transported both 
hazardous materials and nonhazardous materials. The 6 motor coach 
companies we visited included companies that offer intercity services, 
and tour and charter services, as well as companies that do both. 
During our site visits to bus and trucking companies, we interviewed 
officials and inspected a range of security measures. 

To assess how the effectiveness of federal programs to reduce risk was 
being monitored, we analyzed DHS and DOT strategic planning and 
budgeting documents and performance data and interviewed officials from 
TSA's HMC, the Transportation Sector Network Management Business 
Management Office, and the DHS Federal Emergency Management Agency's 
(FEMA) Grants Program Directorate. To determine what performance 
measurement data DOT had developed that TSA could potentially use to 
monitor the progress of these commercial vehicle security programs, we 
interviewed officials from FMCSA's Analysis Division and Strategic 
Planning and Program Evaluation Division. We also compared TSA's 
efforts to evaluate its programs with guidance on performance 
measurement contained in the GPRA and the TSSP. 

Coordination and Collaboration Efforts: 

To review the extent to which the federal government has coordinated 
its strategy for securing commercial vehicles internally and with 
private sector stakeholders, we analyzed DHS's memorandum of 
understanding with DOT and subsequent annex with PHMSA that identifies 
the roles and responsibilities of DHS and DOT related to commercial 
vehicle and hazardous materials transportation security. In addition, 
we reviewed statutes related to DHS and DOT roles and responsibilities, 
as well as regulations and associated comments provided during 
rulemaking procedures for commercial vehicle security programs and 
requirements. We also interviewed officials from TSA's Office of 
Intelligence, Risk Management Division, the Office of Highway and Motor 
Carrier, and the Office of Cargo Policy; and DOT's PHMSA and FMCSA to 
obtain information on their current and planned efforts to secure 
commercial vehicles, as well as their collaborative efforts across 
agencies and with the private sector. We also interviewed members of 
the SCC and the private firms we visited to obtain their views 
regarding the effectiveness of TSA's coordination efforts, and 
discussed their views with TSA officials. Finally, we compared TSA's 
efforts to collaborate and coordinate with stakeholders to key 
practices that we had previously developed as leading practices of 
collaborating agencies.[Footnote 91] 

We conducted this performance audit from September 2006 through 
February 2009 in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. (The 
methodology used to gather our data on the incidents of truck and bus 
bombing is summarized in app. II). 

[End of section] 

Appendix II: Incidents of Truck and Bus Bombings from 1997 to 2008: 

This appendix provides information on the analysis we conducted to 
determine the incidents of truck and bus bombings presented in this 
report. It provides information on the methodology used to identify 
incidents worldwide and the detailed results of our analysis. 

Methodology Used to Identify Bombing Incidents: 

We used open sources, such as press and wire service reports, to 
determine the extent of bus and truck bombings. We first reviewed the 
general strengths and weakness of different open-source databases and 
consulted open source search experts. We reviewed eight databases and 
chose to use four based on the breadth and completeness of their media 
sources, years, and geographic coverage; whether they contained 
sufficient detail to verify that the event was a truck or bus bombing; 
and whether they allowed for independent verification of source 
information. We also wanted databases that had, or enabled, control 
methods to ensure minimization of false positives and duplicates, and 
standardized criteria for incident inclusion. 

We narrowed our selection of databases to the Open Source Center (OSC), 
Nexis, Global Terrorism Database (GTD), and Dialog databases. OSC is 
the official open-source clearinghouse for the U.S. government that 
monitors, translates, and disseminates within the U.S. government 
openly available news and information from non-U.S. media sources. It 
has state of the art language translation capabilities, so articles are 
usually translated into English by native-speaker linguists. Nexis, 
Major World Newspapers provides access to 5 billion searchable 
documents from more than 40,000 legal, news, and business sources. GTD 
is an open-source database gathering information on terrorist incidents 
around the world since 1970. We made limited use of the earlier, first 
version called GTD 1 and only for 1997 when we could corroborate the 
incidents it identified with additional sources found in Nexis. Our 
primary database was the more rigorous GTD2, which currently covers 
terrorism events from 1998 to 2004. GTD2 is based on the OSC and Nexis 
databases, which it evaluated as the best general databases. GTD2 
entries have to be based on multiple independent open-source reports or 
a single "highly credible" source. GTD2 has a configurable definition 
of terrorism that includes more than one definition of the phenomenon; 
control methods in place to ensure minimization of false positives; a 
standardized criteria for incident inclusion that is documented in a 
formal and publicly available codebook; and a ranking system for media 
sources. Dialog is an online database that allows for an extensive 
search of a variety of databases and collections using powerful search 
language. Dialog's ability to identify very specific information made 
it an ideal second source to search for additional documentation on 
known but not fully documented events. 

We then explored the capabilities of these databases over time with a 
small pilot, conducting searches on truck and bus bombings in one 
individual year in each of three decades, specifically the years 1987, 
1996, and 2002, and explored which search terms and strategies produced 
the best results for each database. We assessed the possible threats to 
validity and confirmed that these were the pertinent issues with an 
open-source terrorism data expert. Our analysis plan addressed a 
variety of threats to validity and their mitigation: 

* False positives - Unclassified data on terrorist events are largely 
gathered through open-source data, typically press reports.[Footnote 
92] Since press reports may not be the most reliable, we used several 
databases that use reputable sources and decision rules for the 
inclusion of their entries. Entries we accepted had to be based on a 
highly reliable source, or multiple sources. Supporting articles had to 
directly confirm whether the incident was a truck or bus bombing as 
well as the incident date, location, and the number killed. 

* History - Electronic search engines and archives have improved over 
time. Therefore, data across 25 years, since the 1983 Marine barracks 
bombing, may not be comparable. Based on our pilot data, we only 
included incidents from 1997, by which time both Nexis and GTD were 
well developed and reliable. 

* Language - All languages may not be equally covered. GTD uses the 
Open Source Center which is based entirely on foreign sources and has 
strong translation capabilities among its staff. 

* Synonyms - Multiple English terms may be used for bus, truck and bomb 
(e.g., bus vs. lorry). GTD uses extensive Boolean search terms with 
search strings using hundreds of terms and synonyms. Nexis and Dialog 
enable similar searches with wildcard strings. We applied GTD search 
strings to Nexis and Dialog to cover more current events not yet 
included in GTD. 

* Geography - Some areas (e.g. Africa) may not be covered as well. 
However, we looked for a very particular type of incident that was 
highly likely to be the lead story where it occurred and picked up by 
the wires. 

* Dates -Reporting date vs. actual dates. Reporting dates on global 
time can lead to confusion. GTD and OSC have date protocols to minimize 
date error. Since our unit of analysis is years, this error was of 
little risk. 

* Breaking reports vs. "final" reports - Initial reports usually have 
less confirmation of the number killed. When conflicting reports cannot 
be reconciled, we used the lower number of reported killed. GTD also 
uses the lowest number. 

* Incidents in a military area may not be terrorism - The GTD makes a 
distinction between combatants and noncombatants. We screened out 
events involving active combatants. However, we included incidents 
directed at civilians or other targets in active war zones such as Iraq 
and Afghanistan. 

* Incident duplication - Using multiple sources could inadvertently 
lead to incident duplication. GTD has a protocol to eliminate 
duplicates and Nexis also enables electronic duplication vetting. In 
addition, duplications were screened manually and the entire dataset 
was verified by independent staff. 

Search strategy: 

We originally hoped to list the incidents since the Beirut bombings of 
1983, but given the less rigorous methodology of GTD1, the limited 
archival coverage of Nexis prior to 1996, and the limitations of other 
databases we decided to drop 1983 through 1996. Due to the evolving 
coverage of these databases, we had to employ three different search 
strategies to cover the years from 1997 to 2007. 

Time period: 1997 Primary search database: Global Terrorism Database 
"GTD1" Secondary search database: Nexis' Major World Newspapers: 

By 1997, Nexis sources were sufficiently developed and available online 
to augment GTD1, which did not list supporting sources. 

Time period: 1998-2004 Primary search database: Global Terrorism 
Database "GTD2" GTD2 incorporates OSC and Nexis in a systematic manner 
and additional searches of these sources were not necessary. 

Time period: 2005-present Primary search database: Nexis' Major World 
Newspapers Secondary search database: Individual newswires database in 
Dialog Third search database: Open Source Center: 

For our study we searched the GTD2 for attacks utilizing or against a 
commercial vehicle, either truck, bus, or bus station or bus stand, 
specifically with explosives (VBIEDs, IED's, suicide bomber(s), bombs, 
grenades, roadside bombs, landmines, and rockets). When searching Nexis 
we used the same search factors but with a Boolean search string. For 
years in our study outside the GTD year range, we duplicated their 
search and inclusion methodology. As a final check, we compared our 
results with Department of State and Department of Defense terrorism 
lists and timelines. We believe that these various steps successfully 
mitigated the various threats to validity and enabled us to compile 
information on the incidents of truck and bus bombings since 1997 with 
confidence.

Appendix IV: DHS and DOT Commercial Vehicle Security Programs Designed 
to Strengthen Commercial Vehicle Security: 

In addition to Corporate Security Reviews, TSA and DHS have four key 
programs designed to strengthen the security of the commercial vehicle 
industry. DOT also has four programs underway to strengthen commercial 
vehicle security and TSA and DOT are working collaboratively on several 
projects for securing commercial vehicles. Each of these programs and 
projects are discussed below. 

DHS Security Programs: 

Trucking Security Program: The Trucking Security Program (TSP) provides 
grants that fund programs to train and support the members of the 
commercial vehicle industry in how to detect and report security 
threats, and how to avoid becoming a target for terrorist activity. TSP 
is administered by the Federal Emergency Management Agency's Grant 
Programs Directorate within DHS. As of May 2008, DHS has provided 
nearly $78 million in TSP grants since 2003. Congress appropriated $16 
million to fund this trucking security grant program for fiscal year 
2008, and $8 million for fiscal year 2009. For fiscal years 2004-2008 
the principal activity funded by the TSP was the American Trucking 
Associations' Highway Watch program to improve security awareness in 
the commercial vehicle industry. In May 2008, however, a new grantee, 
the HMS Company of Alexandria, Virginia was selected. 

Security Action Items (SAIs): TSA consulted with DOT and industry 
stakeholders to develop SAIs, or voluntary security practices, intended 
to improve security for trucks carrying security-sensitive hazardous 
materials. TSA eventually plans to also develop SAIs for motor coaches 
and school buses. According to TSA officials, the SAIs will allow TSA 
to communicate the key elements of effective transportation security as 
voluntary practices; TSA officials will use CSRs to gauge whether 
voluntary practices are sufficient or if regulation is needed. 

Hazardous Materials Driver Background Check Program: A Hazardous 
Materials Endorsement (HME) authorizes an individual to transport 
hazardous materials for commerce. The USA PATRIOT Act, enacted in 
October 2001, prohibits states from issuing HMEs for a commercial 
driver's license to applicants who have not successfully completed 
background checks. In response, TSA implemented the hazardous materials 
driver security threat assessment program which evaluates the hazardous 
materials driver's criminal history, immigration status, mental 
capacity, and connection with terrorism to determine whether that 
driver poses a security risk.[Footnote 93] 

Intercity Bus Security Grant Program: This DHS program distributes 
grant money to eligible stakeholders to protect intercity bus systems 
and the traveling public from terrorism. Current priorities focus on 
enhanced security planning, passenger and baggage screening programs, 
facility security enhancements, vehicle and driver protection, as well 
as training and exercises. A total of $11.5 million was appropriated 
for fiscal year 2008 and $12 million for fiscal year 2009. A total of 
$11.5 million was appropriated for fiscal year 2008 and $12 million for 
fiscal year 2009.[Footnote 94] 

DOT Security Programs: 

Security Plans and Training: DOT regulations require shippers and 
carriers of certain hazardous materials to develop and implement 
security plans. [Footnote 95] The regulations permit a company to 
implement a security plan tailored to its specific circumstances and 
operations. At a minimum, a security plan must address personnel, 
access, and en route security. All shippers and carriers must also 
ensure that employee training includes a security awareness component. 
In response to an industry petition that certain hazardous materials 
posing little or no security risk be removed from the list of hazardous 
materials for which security plans are required, DOT is reevaluating 
the security plan regulations. 

Security Contact Reviews (SCRs): Through its SCRs, FMCSA conducts 
compliance reviews of the security plans for hazardous materials 
transport required by DOT hazardous materials regulations. FMCSA 
conducts SCRs on all hazardous materials motor carriers that transport 
placardable amounts of hazardous materials. As of September, 2008, 
FMCSA had conducted 7,802 SCRs since the inception of the programs. 

Hazardous Materials Safety Permit Program: Federal law directed FMCSA 
to implement the hazardous materials permit program to produce a safe 
and secure environment to transport certain types of hazardous 
materials.[Footnote 96] The program requires certain motor carriers to 
maintain a security program and establish a system of enroute 
communication. This program uses the SCRs to collect data on motor 
carrier ability to secure hazardous materials. 

Sensitive Security Visits (SSVs): FMCSA conducts SSVs as educational 
security discussions with motor carriers that carry small amounts of 
hazardous materials that do not require posting hazardous materials 
placards on their trucks. These visits discuss best practices for 
hazardous materials transportation and provide informal suggestions for 
improvement. As of September, 2008, FMCSA had conducted 13,411 SSVs 
since the inception of the programs. 

TSA and DOT Joint Security Programs: 

TSA Missouri CSR Pilot: This pilot program conducts abbreviated CSRs of 
trucking and motor coach companies using state inspectors. For more 
details of the Missouri CSR program, see pages 26-31. 

FMCSA and TSA Truck Tracking Security Pilots: FMCSA and TSA have 
concluded hazardous materials truck-tracking pilots. FMCSA completed a 
study of existing technologies in December 2004, evaluating wireless 
communications systems, including global positioning satellite (GPS) 
tracking and other technologies that allow companies to monitor the 
location of their trucks and buses. TSA also tested tracking and 
identification systems, theft detection and alert systems, motor 
vehicle disabling systems, and systems to prevent unauthorized 
operation of trucks and unauthorized access to their cargos. The 9/11 
Commission Act mandated that the Secretary develop a tracking program 
for motor carrier shipments of hazardous materials by February 
2008.[Footnote 97] TSA officials reported that they worked with DOT to 
meet this mandate and completed a program to facilitate truck tracking 
on January 10, 2008. 

Hazardous Materials Research Involving Security Initiatives: DOT and 
DHS sponsor research on emerging technology that could potentially be 
used to enhance the safety and security of hazardous materials 
transportation. This research involves evaluation of potential truck- 
disabling technologies, radiation detection devices, hazardous 
materials routing, and software to assist in hazardous materials 
incident response. 

Additional Programs: DHS and TSA also have a number of smaller programs 
to augment motor carrier security and programs in the planning stages. 
TSA has several projects on screening applicants for Commercial Drivers 
Licenses (CDLs) and Hazardous Materials Endorsements on CDLs. These 
include the Universal CDL Vetting Project, which will assess the 
feasibility of implementing watch list checks of 9 million commercial 
driver records. Through the Rental Truck Vetting Operational Study and 
Analysis, TSA is assessing technologies to screen rental truck 
customers against the DHS and FBI Watch List. To address the lack of 
security-related domain awareness, TSA and DHS also have developed 
several projects: Federal Law Enforcement Training Center (FLETC) 
Roadside Law Enforcement Transportation Security Awareness, and the 
Hazmat Motor Carrier Security Self-Assessment Training Project which 
distributed security self-assessment training on CDs to approximately 
75,000 hazardous materials motor carriers and shippers. Through the 
Commercial Truck Insurance Initiative, TSA is coordinating with 
insurance companies to develop methods and measures to provide 
companies incentives to improve security.

Appendix V: DOT Data on the Commercial Vehicle Industry: 

DOT maintains data on carriers and commercial vehicles registered with 
DOT. However, the data on intrastate operations is incomplete and 
unreliable because FMCSA does not have authority to regulate intrastate 
operations that are not involved in the transport of hazardous 
materials. Firms that operate exclusively within a single state do not 
have to register with DOT unless they are in the 25 states that require 
all commercial vehicles to register with DOT, or transport hazardous 
materials. This means that DOT does not have data on approximately half 
the nation's intrastate carriers. Second, firms frequently do not keep 
their registrations current, and as a result the currency and accuracy 
of DOT's records are not assured and many of its registrations are 
inactive. "Inactive" means that carriers had no inspections, crashes, 
enforcement actions, compliance reviews, safety audits, or registration 
applications with DOT for 3 years. DOT does not know which firms have 
gone out of business and which have simply failed to maintain their 
registrations. These incomplete data on the population of commercial 
vehicle firms will present some additional challenges to TSA for 
conducting a truly representative sample of industry assessments.

U.S. Department of Homeland Security: 
Washington, DC 20528: 

Homeland Security: 

February 6, 2009: 

Ms. Cathleen A. Berrick: 
Director, Homeland Security and Justice Issues: 
U.S. Government Accountability Office: 
441 G Street, NW: 
Washington, DC 20548: 

Dear Ms. Berrick: 

RE: Draft Report GAO-09-85, Commercial Vehicle Security: Risk-Based 
Approach Needed to Secure the Commercial Vehicle Sector (GAO Job Code 
440538) 

The Department of Homeland Security (Department) appreciates the 
opportunity to review and comment on the draft report referenced above. 
The Department, specifically the Transportation Security Administration 
(TSA), agrees with the four recommendations. We value the U.S. 
Government Accountability Office's (GAO's) extensive review of TSA's 
progress in addressing commercial vehicle security needs. 

Progress continues to be made in several commercial vehicle security 
programs referenced in the report as noted below. 

Risk Assessments:  

TSA is conducting separate risk assessments of highway components. TSA 
examines potential indicators of terrorist activity including the 
capabilities and intent of terrorists. This examination involves 
searching open source information along with a careful and thorough 
examination of classified information. 

In accordance with the provisions of the "Implementing Recommendations 
of the 9/11 Commission Act of 2007" (9/11 Act), TSA is conducting risk 
assessments on school bus transportation and commercial vehicle 
security, including general freight trucking, hazardous materials 
trucking, and bulk food transportation trucking. These risk assessments 
are expected to be completed by February 2009 and May 2009, 
respectively. In addition to the above, TSA is also conducting risk 
assessments on motor coach transportation, port and trucking interface, 
and highway infrastructure. 

TSA is actively working on the truck security assessment required under 
section 1540 of the 9/11 Act and as required will develop a 
comprehensive report which will include [hyperlink, http://www.dbs.gov] 
assessments of (1) actions already taken by private and public entities 
to address security risks, (2) economic impacts of security upgrades of 
trucks, (3) ongoing research by public and private entities, and (4) 
the current status of secure truck parking. 

TSA/U.S. Department of Transportation Memorandum of Understanding:  

TSA and the U.S. Department of Transportation (USDOT) have signed an 
overarching Memorandum of Understanding (MOU) for commercial vehicle 
security. TSA and the Federal Motor Carrier Safety Administration 
(FMCSA) have exhaustively discussed common programs and shared 
approaches to the variety of security programs needed. Many of those 
shared programs have become key cooperative elements in the 
Transportation Systems Sector-Specific Plan (TSSSP). Both agencies 
agreed during TSSSP discussions to incorporate TSSSP program agreements 
into MOU formats. That final step was completed when the MOU was signed 
by FMCSA and TSA on October 22, 2008. 

Corporate Security Reviews:  

Since the review by GAO, TSA has enlisted several additional states to 
conduct Corporate Security Reviews (CSR). Colorado and Michigan state 
commercial vehicle safety enforcement officers have been trained and 
have been performing CSRs over the past several months. The State of 
Arkansas will participate and the state commercial vehicle safety 
enforcement officers will receive training in June of 2009. TSA's 
Highway and Motor Carrier Division also is in the process of training 
150 TSA Surface Transportation Security Inspectors (STSI) throughout 
the United States to conduct CSRs. Training has been conducted in 
Dallas, Washington, D.C., and Los Angeles to date, and additional 
training is scheduled for Philadelphia, Seattle and Chicago. 

As of December 2008, TSA has conducted 153 CSRs, encompassing 102 CSRs 
of motor carriers (15 motor coach companies, 20 school bus 
companies/districts, and 67 trucking companies). TSA has conducted 46 
CSRs of state DOTs, including 3 revisits to previously reviewed states, 
and 5 CSRs of infrastructure facilities. 

TSA is launching a voluntary program to measure the security 
preparedness of the hazardous materials trucking industry. TSA is 
utilizing its STSI force to conduct CSR visits. TSA will select a 
statistically valid sample of motor carriers transporting hazardous 
materials to request that they voluntarily participate in a CSR. This 
will allow TSA to measure the current level of preparedness for 
terrorist incidents involving trucks transporting hazardous materials. 
TSA plans to conduct annual CSRs on a recurring basis to determine 
whether the trucking industry is following current security regulations 
as well as voluntary Security Action Items (SATs) established by TSA. 

TSA's mission includes ensuring the secure movement of people, goods, 
and services for those using highways, roads, intermodal terminals, 
bridges, and tunnels. This includes all aspects of the transport of 
persons and cargo by commercial and non-commercial buses, trucks, and 
school buses. Although the report analyzes TSA's efforts to secure the 3
"commercial" motor carrier community, TSA's responsibility to address 
large vehicles capable of delivering terrorist weapons of extraordinary 
destructive force extends well beyond the "for hire" motor carriers who 
fall under the jurisdiction of other federal transportation regulators. 
TSA must also ensure that the security of private motor carriers and 
those who may not operate in interstate commerce are addressed as well. 
Highway security is a huge task. 

Implementation of Recommendations:  

The recommendations provide TSA with a useful analysis of TSA's current 
approach regarding commercial vehicle security, recognition of progress 
to date, and additional guidance for success. TSA is accomplishing much 
of what GAO recommends and is formulating additional plans to fulfill 
the recommendations. 

Recommendation 1: The Assistant Secretary for the TSA establish a plan 
and a timeframe for completing risk assessments of the commercial 
vehicle sector, and use this information to support future updates to 
the Transportation Sector Strategic Plan, including: 

* to the extent feasible, conduct assessments that include information 
about the likelihood of a terrorist attack method on a particular 
asset, system or network as required by the National Infrastructure 
Protection Plan; 

* conducting a vulnerability assessment of the commercial vehicle 
sector, including: 

- assessing the scope and method of assessments required to gauge the 
sector's vulnerabilities; 

- considering the findings and recommendations of [the] Missouri pilot 
evaluation report to strengthen future Corporate Security Reviews; and 

- enhancing direct coordination with state governments to expand the 
TSA's field inspection CSR capacities; 

* conducting consequence assessments of the commercial vehicle sector, 
or develop alternative strategies to assess potential consequences of 
attacks, such as coordinating with other Sector Specific Agencies to 
leverage their consequence assessment efforts. 

Response: 

TSA is actively conducting risk assessments of the major components of 
the commercial vehicle sector. This includes assessments of the 
trucking industry (general trucking, hazardous materials trucking, and 
segments of bulk food trucking) and school buses as required under the 
9/11 Act. TSA is also conducting risk assessments of the motor coach 
industry, highway infrastructure, and the interface of the domestic 
trucking industry with U.S. ports. These assessments will examine 
specific scenarios involving individual 4
components of the commercial vehicle sector and will include 
information on the likelihood of a terrorist attack method on an asset, 
system, or network. TSA also is committed to a cross comparison of the 
risk analysis for all of these elements of the commercial vehicle 
sector. TSA's goal is to complete these risk assessments in the 
following timeframes: 

Highway Sector: School Bus; 
Date: February 2009. 

Highway Sector: Trucking; 
Date: May 2009. 

Highway Sector: Motor Coach; 
Date: May 2009.

Highway Sector: Highway Infrastructure; 
Date: July 2009.  

Highway Sector: Trucking-Port Interface; 
Date: July 2009. 

Highway Sector: Cross Comparison of Highway/Motor Carrier Risks; 
Date: October 2009. 

In developing the risk assessments, TSA relies upon federal and state 
government subject matter experts and specific private sector 
stakeholders to identify potential vulnerabilities that may make the 
structure susceptible to terrorist attacks. This takes place through 
the framework of scenarios that carefully identify specific elements 
such as attack mode, attack type, and access to target. When 
appropriate, TSA will consult with Sector Specific Agencies. 

TSA also examines consequence information based on the scenarios that 
have been developed. TSA relies upon public and private sector subject 
matter experts to identify potential consequences and draws upon data 
from the Department of Transportation's Federal Motor Carrier Safety 
Administration, Federal Highway Administration, and Pipeline and 
Hazardous Materials Safety Administration; the Federal Bureau of 
Investigation; and the Bureau of Alcohol, Tobacco, Firearms, and 
Explosives. TSA experts in risk analysis and explosives also provide 
information on consequences. TSA will continue using this methodology 
to identify the potential consequences of terrorist actions on 
transportation and, when appropriate, will consult with Sector Specific 
Agencies. 

As previously noted, in addition to working with the State of Missouri, 
TSA has worked with the states of Colorado and Michigan to set up CSR 
programs. TSA has provided extensive training to these states in 
conducting and reporting on CSRs. TSA also is launching a voluntary 
program to measure security preparedness in the hazardous materials 
trucking industry. TSA is training its Federal Security Director staffs 
and Surface Transportation Security Inspectors to conduct CSRs. Using 
these field resources, TSA will select a statistically valid sample of 
motor carriers transporting hazardous materials and request they each 
voluntarily participate in a CSR. This will allow TSA to clearly 
measure the current level of preparedness for terrorist incidents 
involving trucks transporting hazardous materials. TSA plans to conduct 
CSRs annually to assess changes in preparedness in the hazardous 
materials trucking industry. 

Recommendation 2: In future updates to the Highway Infrastructure and 
Motor Carrier Annex to the Transportation Sector Security Plan, the 
Assistant Secretary for the TSA should clarify the basis for the 
agency's security strategy of focusing on the transportation of 
hazardous materials, the relative risk of vehicle borne improvised 
explosive devices to the sector, and, based on the relative risk of 
these threats, any risk mitigation activities that will be implemented 
to address them. 

Response: 

As TSA develops future updates to the Transportation Systems Sector 
Specific Plan Highway Infrastructure and Motor Carrier Annex, it 
intends to include risk-based clarification of the security strategies. 
Although for the past two years TSA has primarily focused on the 
transportation of hazardous materials, ongoing industry risk 
assessments and regulatory efforts may shift the current strategies, 
and communicating these strategies in the annex to all stakeholders 
will be critical to successful implementation of the TSSSP. TSA 
anticipates that the updated Highway Infrastructure and Motor Carrier 
Annex to the TSSSP will better enable the communication of the security 
strategies, including the risks and associated mitigation efforts, 
stakeholder roles and responsibilities. 

Recommendation 3: The Assistant Secretary of the TSA develop outcome-
based performance measures, to the extent possible, to assess the 
effectiveness of federal programs to enhance the security of the 
commercial vehicle sector. 

Response: 

TSA recognizes the importance of establishing outcome-based performance 
measures for any and all programs developed and implemented to 
strengthen security. Within the highway mode, TSA's Hazardous Materials 
(HAZMAT) Endorsement Threat Assessment Program requires that security 
threat assessments be completed on commercial drivers requesting a 
HAZMAT endorsement for their commercial drivers license (CDL). The 
outcome-based measure for this program is directly correlated to the 
number of HAZMAT endorsements approved in relation to the total CDL 
population. The majority of the other highway modal security efforts 
within TSA have been establishing baseline voluntary guidelines and 
training tools as well as industry risk assessments. It is premature to 
use outcome-based measures on these new and voluntary efforts, thus 
output measurements were and are being used. As the regulations from 
the 9/11 Act are completed and finalized, the resulting programs will 
have outcome based measures. One example of TSA's efforts to establish 
baseline and follow-on measurements is in the CSR initiative. TSA is 
creating a database to compile the results of statistically valid CSR 
visits which are being conducted nationwide on hazardous materials 
motor carriers beginning in 2009. TSA will conduct these CSRs annually 
to measure changes in industry security against a potential terrorist 
event targeting the hazardous materials highway transportation 
component. 

Recommendation 4: The Assistant Secretary for the TSA establish a 
process to strengthen coordination with the commercial vehicle 
industry, including ensuring that roles and responsibilities of 
industry and government are fully defined and clearly communicated; new 
approaches to enhance communication are considered; and monitoring and 
assessing the effectiveness of its coordination efforts. 

Response: 

Recognizing the importance of having and maintaining strong working 
relationships with both industry and other government agencies, and 
working through the Government Coordinating Council/Sector Coordinating 
Councils (GCC/SCC) security partnership framework established in the 
National Infrastructure Protection Plan (NIPP), TSA has established an 
industry/government coordination process that continues to mature and 
develop. TSA recognizes the need to specifically define roles and 
responsibilities with all highway security stakeholders, including 
industry and federal, state, local, and tribal governments. The 
appropriate place for defining roles and responsibilities as well as 
communications methods and measurement efforts is in the TSSSP modal 
annex. TSA will include a "roles and responsibilities" section and a 
"communications" section during the TSSSP rewrite in 2009. In terms of 
monitoring and assessing the effectiveness of the coordination efforts, 
TSA continues to build security partnerships under the newly defined 
GCC/SCC organizations as established in the NIPP and TSSSP. As the 
coordination efforts under these strategic plans are only 17 months 
old, the measuring and assessing processes are also new and continue to 
be refined so as to improve the coordination and communications efforts 
to be the most effective and efficient possible.

[15] Some of these inspections are funded through FMCSA's Motor Carrier 
State Assistance Program (MCSAP), which provides financial assistance 
to certain state and local jurisdictions. This assistance may be used 
to conduct compliance reviews of state safety regulations. MCSAP is a

[25] Specifically, the subset of hazardous materials requiring security 
plans includes: (1) a highway route-controlled quantity of a Class 7 
(radioactive) material; (2) more than 25 kg (55 lbs) of a Division 1.1 
(explosive with a mass explosion hazard), 1.2 (explosive with a 
projection hazard), or 1.3 (explosive with predominately a fire hazard 
material); (3) more than 1 L (1.06 qt) per package of a toxic by 
inhalation (TIH) material of a specified concentration level; (4) a 
shipment of hazardous materials in bulk packaging having a capacity of 
13,248 L (3,500 gallons) or more for liquids or gases or more than 
13.24 cubic meters (468 cubic feet) for solids; (5) a shipment in other 
than bulk packaging of 2,268 kg (5,000 lbs) gross weight or more of one 
class of hazardous materials for which placarding is required; (6) a 
select agent or toxin regulated by the Centers for Disease Control and 
Prevention; and (7) a quantity of hazardous materials that requires 
placarding. 49 C.F.R. § 172.800. 

[26] The component to which surface transportation grant funding has 
been appropriated has changed over time, due largely to DHS 
restructuring. TSA distributed the transportation security grants until 
fiscal year 2005, when the DHS Office for State and Local Government 
Coordination and Preparedness assumed responsibility for issuing and 
administering the grants. During fiscal year 2008, the grant funding 
was appropriated to FEMA, which is currently responsible for 
distributing the grants. 

[27] As of May 2008, TSA HMC had 17 staff including two personnel in 
the risk assessment (TVC) branch, five in trucking, four for licensing 
and infrastructure, and three for policy, plans and stakeholder 
coordination. HMC had two staff vacancies. 

[28] Industry shares are by tonnage. 

[29] DOT data on carriers are as of August 2008. 

[30] Federal hazardous transportation law defines a hazardous material 
as a substance or material that the Secretary of Transportation has 
determined is capable of posing an unreasonable risk to health and 
safety or property when transported in commerce. 49 U.S.C. § 5103. It 
includes a variety of substances such as explosive or radioactive 
material and toxic materials such as anhydrous ammonia, sulfuric acid, 
or chlorine. 

[31] The hazard class of dangerous goods is indicated either by its 
class (or division) number or name. Most classes also are further 
broken out into subsidiary hazard classes. Placards are used to 
identify the class or division of a material to first responders. Class 
1 are explosives which are further subdivided into explosives with a 
hazard of mass explosion, projection, fire, etc; Class 2 are flammable, 
nonflammable and nontoxic gases, and toxic gases; Class 3 are flammable 
liquids and combustible liquids such as gasoline; Class 4 are flammable 
solids, spontaneously combustible materials, and water- reactive, 
dangerous-when-wet materials; Class 5 are oxidizing substances and 
organic peroxides; Class 6 include toxic or poisonous substances such 
as TIH and infectious substances; Class 7 are radioactive materials, 
Class 8 are corrosive substances; and class 9 are miscellaneous 
hazardous materials, products, substances, or organisms. 

[32] Toxic Inhalation Hazards are a gas or volatile liquid which is 
known to be so toxic to humans as to pose a hazard to health during 
transportation, or in the absence of adequate data on human toxicity, 
is presumed to be toxic to humans based on tests on laboratory animals.

[34] DHS serves as the sector-specific agency for 11 of the 18 sectors: 
information technology; communications; transportation systems; 
chemical; emergency services; nuclear reactors, material, and waste; 
postal and shipping; dams; government facilities; critical 
manufacturing and commercial facilities. Other sector-specific agencies 
are the Departments of Agriculture, Defense, Energy, Health and Human 
Services, Interior, Treasury, and the Environmental Protection Agency.

Councils Continue to Improve, GAO-07-706R (Washington, D.C.: July 10,

[36] The NIPP defines threat as: The likelihood that a particular 
asset, system, or network will suffer an attack or an incident. In the 
context of risk from terrorist attack, the estimate of this is based on 
the analysis of the intent and the capability of an adversary; in the 
context of natural disaster or accident, the likelihood is based on the 
probability of occurrence. 

[37] Motor carriers include commercial vehicles and school buses. 

[38] TSA officials also stated that the Aviation Domain Risk Assessment 
(ADRA) developed in response to HSPD-16 was a more comprehensive risk 
assessment of the aviation industry, with 117 scenario-based risk 
assessments with likelihood estimates. We were not provided the 
opportunity to review the NTSRA or the ADRA before completing our work, 
and we could not assess their validity. 

[39] This is the most recent information provided by TSA. The agency 
has also conducted 44 CSRs on state DOTs and 6 bridge and tunnel 
authorities. 

[40] The draft best practices are called the Uniform Security Template. 
In addition, specific voluntary best practices for hazardous materials 
carriers, called Strategic Action Items, were developed. 

[41] Through an earlier contract with the American Bus Association, TSA 
developed and released a list of recommended security practices for 
motor coach operators in October 2005. 

[42] This program is generally referred to as the MCSAP. 

[43] FMCSA decides which motor carriers to review for compliance with 
its safety regulations primarily by using an algorithm called SafeStat 
to identify high-risk carriers. GAO analyzed two alternative approaches 
to better identify commercial carriers that pose high crash risks: GAO, 
Motor Carrier Safety: A Statistical Approach Will Better Identify 
Commercial Carriers That Pose High Crash Risks Than Does the Current 
Federal Approach, [hyperlink, http://www.gao.gov/products/GAO-07-585] 
(Washington, D.C.: June 11, 2007); and Motor Carrier Safety: Federal 
Safety Agency Identifies Many High-Risk Carriers but Does Not Assess 
Maximum Fines as Often as Required by Law, [hyperlink, 
http://www.gao.gov/products/GAO-07-584] (Washington, D.C.: Aug. 28, 
2007). All new firms registering with DOT are also subject to these 
safety inspections. 

[44] The report also noted difficulties throughout the CSR data 
collection process, from questionnaire design through analysis and 
reporting. For example, because the Missouri CSRs did not identify 
carriers delivering different types of cargo on the questionnaire, the 
contractor lacked a formal mechanism for selection of hazardous 
material transport companies for review, and it is likely that the 14 
hazardous materials carriers identified do not represent the full set 
of hazardous materials carriers among the 1251 cases studied. 

[45] Monitoring of internal control should include policies and 
procedures for ensuring that the findings of audits and other reviews 
are promptly resolved. Managers are to (1) promptly evaluate findings 
from audits and other reviews, including those showing deficiencies and 
recommendations reported by auditors and others who evaluate agencies' 
operations; (2) determine proper actions in response to findings and 
recommendations from audits and reviews; and (3) complete, within 
established time frames, all actions that correct or otherwise resolve 
the matters brought to management's attention. See GAO, Standards for 
Internal Control in the Federal Government, [hyperlink, 
http://www.gao.gov/products/GAO/AIMD-00-21.3.1] (Washington, D.C.: 
November 1999) pp. 21-22. 

[46] TSA Federal Security Directors (FSDs) are the ranking TSA 
authorities responsible for the leadership and coordination of TSA 
security activities at commercial airports regulated by TSA. 

[47] Going forward, TSA reported that it will identify CSR targets 
based on risk factors including the safety records of commercial motor 
carriers, business factors, data on theft, and a focus on select 
hazardous materials such as toxic inhalation hazards. TSA could not 
provide documentation that it had validated this approach and that 
these factors were valid indicators of likely levels of security 
practices. TSA contracted with Oak Ridge National Laboratory to develop 
a risk-based CSR selection procedure, but this report has not been 
finalized. 

[48] TSA also had acquired an Argonne National Laboratory report that 
provides additional predictive information that expands on the 
Protective Action Distances for Toxic Inhalation Hazard incidents 
provided in the Emergency Response Guidebook: David F. Brown, Safe 
Distance Estimates for Selected Toxic-by-Inhalation Materials, Argonne 
National Laboratory (Argonne, Ill.: 2003). TSA has also consulted the 
Defense Threat Reduction Agency on specific scenarios. 

[49] Security self-assessments could provide additional data on 
industry vulnerabilities, and TSA developed Web-based security self- 
assessment training for hazmat motor carriers and shippers. 

[50] In September 2008 TSA officials stated that the contractor was 
conducting 80 to 100 scenarios using industry experts for the highway 
and motor carrier sector. TSA stated that these scenarios would cover 
general freight, transportation of food commodities and hazardous 
materials, IEDs, and VBIEDs. 

[51] For example, a full analysis of vulnerability, the likelihood of 
an attack succeeding, includes assessing how well potential targets 
have mitigated risks. Accordingly, the 9/11 Commission Act also 
mandated that TSA complete and report an assessment of actions already 
taken by both public and private entities to address identified 
security risks to the trucking industry. Scenarios alone cannot assess 
the incidence and quality of mitigation efforts. Without a 
comprehensive CSR program, or a survey of private sector actions, TSA 
will not be able to methodically assess private security activity. 

[52] See GAO, Information Sharing Environment: Definition of the 
Results to Be Achieved in Improving Terrorism-Related Information 
Sharing Is Needed to Guide Implementation and Assess Progress, 
[hyperlink, http://www.gao.gov/products/GAO-08-492] (Washington, D.C.: 
June 25, 2008), p. 13. 

[53] The Trucking Security Program (TSP) provides grants that fund 
programs to train and support the members of the commercial vehicle 
industry in how to detect and report security threats, and how to avoid 
becoming a target for terrorist activity. The 9/11 Commission Act 
required the DHS Inspector General to prepare an initial report on the 
Trucking Security Program, which was issued in October 2007 and 
described the announcement, application, receipt, review, award, and 
monitoring processes, and summarized the expenditures related to fiscal 
year 2004 and 2005 grants. Office of the Inspector General, Department 
of Homeland Security, Administration of the Federal Trucking Industry 
Security Grant Program for FY 2004 and FY 2005, OIG-08-08 (Washington, 
D.C.: Oct. 29, 2007). The 9/11 Commission Act also required the DHS 
Inspector General to prepare a report by August 2008 that analyzes the 
performance, efficiency, and effectiveness of the trucking security 
grant program. Pub. L. No. 110-53, § 1542, 121 Stat. 266, 469 (2007). 

[54] In addition, the Transportation Sector Annual Report notes that 
the DHS Science and Technology Explosives Division and is working on 
improving existing explosive detection methods and technologies, 
including for IEDs and VBIEDS. 

[55] 49 C.F.R. pt. 1572. TSA is utilizing a phased-in implementation 
over 5 years and expects that all drivers with a hazardous materials 
endorsement on a commercial driver's license will have obtained a TSA 
fingerprint-based background check by May 31, 2010. To mitigate the 
risk of potentially dangerous drivers retaining an HME until the end of 
the implementation period, in September, 2006 TSA conducted name-based 
intelligence checks of all drivers who have HMEs. 

[56] Most of these are trucking firms, but a few bus companies also 
transport some of the less dangerous hazardous materials. 

[57] 49 C.F.R. §§ 172.800-172.804.

[63] TSA officials stated that they also supported a FEMA decision to 
require bus security grant applicants this year to have in place a 
vulnerability assessment and a comprehensive plan. 

[64] State governors also work collectively through the National 
Governor's Association (NGA) which has surveyed its members on their 
homeland security progress in developing homeland security structures, 
priorities, and programs, but NGA does not have any specific committees 
for commercial vehicle security. 

[65] States conduct both roadside inspections of trucks and on-site 
company inspections. 

[66] DHS supports fusion centers by providing financial assistance, the 
majority of which has flowed through the Homeland Security Grant 
Program. All of the states we interviewed had state or regional fusion 
centers to coordinate safety and security monitoring and response. 

[67] However, as previously noted, due to design problems the accuracy 
of the report's findings regarding both hazardous materials and small 
carriers could not be assured.
