Motor Carrier Safety Assistance

Program Information

Popular name

(MCSAP )

Program Number

20.218

Program objective

The Motor Carrier Safety Assistance Program (MCSAP) is a Federal formula grant program that provides financial assistance to States to reduce the number and severity of crashes and hazardous materials incidents involving commercial motor vehicles (CMV). The goal of the MCSAP is to reduce CMV-involved crashes, fatalities, and injuries through consistent, uniform, and effective CMV safety programs. Investing grant monies in appropriate safety programs will increase the likelihood that safety defects, driver deficiencies, and unsafe motor carrier practices will be detected and corrected before they become contributing factors to crashes.

Additional program information

  1. 2016

    Similar to 2015. Within FY 2016 the following national safety elements were reached:

    • 3,294,578 CMV safety inspections conducted; • 412,487 CMV traffic violations identified; • 35,769 safety audits of new motor carriers conducted; • 6,269 compliance investigations of motor carriers initiated, and • 878,919 out of service safety violations identified.

    The above accomplishments were achieved by the 55 States and U.S. Territories that were recipients of MCSAP funds within FY 2016. These efforts provided the majority of national CMV and passenger carrier safety enforcement supported through FMCSA.

  2. 2018

    Fiscal Year 2018: Within the current fiscal (FY 2018), over 2 million CMV inspections have been conducted under the auspices of this program, leading to safer highways with over 400,000 out of service (OOS) violations issued. This data also feeds FMCSA’s various safety data systems, allowing the Agency and its State partners to direct enforcement resources as necessary. The FMCSA has also launched its multi-year Commercial Vehicle Safety Plan (CVSP) project, allowing States to submit Plans (required for MCSAP eligibility) covering a three-year time span. This reduces administrative burdens on the State and FMCSA, while also enhancing the ability to effectively assess commercial vehicle safety impact over a specific time-period.

  3. 2019

    Fiscal Year 2019: According to the FMCSA’s most recently published “Large Truck and Bus Statistics”, over 3 million CMV inspections have been conducted under the auspices of this program, leading to safer highways with over 600,000 out of service (OOS) violations issued. This data also feeds FMCSA’s various safety data systems, allowing the Agency and its State partners to direct enforcement resources as necessary. The FMCSA has also launched its multi-year Commercial Vehicle Safety Plan (CVSP) project, allowing States to submit Plans (required for MCSAP eligibility) covering a three-year time span. This reduces administrative burdens on the State and FMCSA, while also enhancing the ability to effectively assess commercial vehicle safety impact over a specific time-period.

  4. 2020

    Fiscal Year 2020: According to the FMCSA’s most recently published “Large Truck and Bus Statistics”, approximately 3.4 million CMV inspections have been conducted under the auspices of this program, leading to safer highways with over 670,000 out of service (OOS) violations issued. This data also feeds FMCSA’s various safety data systems, allowing the Agency and its State partners to direct enforcement resources as necessary. The FMCSA finalized the launch of its multi-year Commercial Vehicle Safety Plan (CVSP) project, allowing States to submit Plans (required for MCSAP eligibility) covering a three-year time span. In addition, the FMCSA was able to complete critical updates to its MCSAP calculation formula (for use in FY 2021) and regulatory framework as required under the Fixing America’s Surface Transportation (FAST) Act.

  5. 2021

    According to the FMCSA’s most recently published “Large Truck and Bus Statistics”, approximately 3.4 million CMV inspections have been conducted under the auspices of this program, leading to safer highways with over 670,000 out of service (OOS) violations issued. This data also feeds FMCSA’s various safety data systems, allowing the Agency and its State partners to direct enforcement resources as necessary. FMCSA successfully implemented the new MCSAP allocation formula and regulatory framework as required under the Fixing America’s Surface Transportation (FAST) Act.

  6. 2023

    Fiscal Year 2023: The Infrastructure Investment and Jobs ACT (IIJA), also known as the Bipartisan Infrastructure Law (BIL), was passed early in FY22. Dollar amounts by State have been determined by the allocation formula. Information about the changes in the program can be found within the FMCSA Motor Carrier Safety Assistance Program Comprehensive Policy located on the FMCSA website https://www.fmcsa.dot.gov/mission/grants/grantee-resources. FMCSA emphasizes the importance of safe commercial vehicle operation within highway construction zones, enforcement of traffic laws designed to mitigate driver behaviors associated with crashes (i.e. distracted driving), and the importance of detecting carriers operating in an out-of-service status as core parts of its FY 2023 MCSAP Grant. In addition, FMCSA placed significant emphasis on the improvement of commercial vehicle safety in-line with the strategies contained within the Department of Transportation’s National Roadway Safety Strategy (NRSS). This also includes renewed emphasis on areas where CMV and public safety intersect, such as combatting human trafficking and drug interdiction.

  7. 2024

    Fiscal Year 2024: The Infrastructure Investment and Jobs ACT (IIJA), also known as the Bipartisan Infrastructure Law (BIL), was passed early in FY22. Dollar amounts by State have been determined by the allocation formula. Information about the changes in the program can be found within the FMCSA Motor Carrier Safety Assistance Program Comprehensive Policy located on the FMCSA website https://www.fmcsa.dot.gov/mission/grants/grantee-resources. FMCSA emphasizes the importance of safe commercial vehicle operation within highway construction zones, enforcement of traffic laws designed to mitigate driver behaviors associated with crashes (i.e. distracted driving), and the importance of detecting carriers operating in an out-of-service status as core parts of its FY 2024 MCSAP Grant. In addition, FMCSA placed significant emphasis on the improvement of commercial vehicle safety in-line with the strategies contained within the Department of Transportation’s National Roadway Safety Strategy (NRSS). This also includes renewed emphasis on areas where CMV and public safety intersect, such as combatting human trafficking and drug interdiction.

  8. 2025

    Fiscal Year 2025: Continuing to build upon the role played by the MCSAP National Program Elements established in 49 CFR § 350.203 and supported by IIJA/BIL funding, FMCSA is encouraging all MCSAP participants to review their jurisdiction’s crash statistics and engage in high-visibility efforts to combat the large number of CMV crashes and fatalities. MCSAP lead agencies should partner with other State, local safety departments, and educational research institutions where appropriate, to address CMV crashes. If the MCSAP lead agency is engaging in partnership efforts with other State, local agencies, or educational research institutions FMCSA asks they ensure it is accurately reflected within their Commercial Vehicle Safety Plan (CVSP). In response to IIJA/BIL requirements, the Crash Causal Factors Program (CCFP) is being established to carry out a comprehensive study to determine the causes of, and contributing factors to, crashes that involve a commercial motor vehicle. The CCFP is an evolutionary safety initiative moving from a crashworthiness to crash avoidance focus. Current data collections tend to be focused on the survivability of crashes, but the CCFP will provide critical insights into causal factors contributing to these crashes thereby enabling identification and development of appropriate countermeasures to reduce the occurrence of CMV crashes. While FMCSA is currently merging and analyzing available datasets (e.g., from the National Highway Traffic Safety Administration, Federal Highway Administration (FHWA), FMCSA) to gain a more complete picture of crashes, no existing dataset adequately captures all important causal factors. The upcoming CCFP will fill this gap, allowing FMCSA to identify the key factors that contribute to CMV crashes.
