The Commercial Vehicle Enforcement Division (CVED) within Transportation Safety Services (TSS) is comprised of the Motor Carrier Safety Unit (MCSU), the Towing and Recovery Unit (TRU), and the Motor Vehicle Inspection Unit (MVI). Each of these units works to improve public safety by working with industry to gain compliance with the applicable Federal and State regulations through education and uniform enforcement. The CVED is under the command of a State Police Captain and is staffed by a team of approximately 100 commissioned and 30 non-commissioned personnel under the oversight of the TSS Command Inspector.

Motor Carrier Safety Unit (MCSU)

MCSU - History

In 1985, the State of Louisiana entered into an agreement with the United States Department of Transportation (USDOT) to uniformly enforce the Federal Motor Carrier Safety Regulations (FMCSR) and the Federal Hazardous Material Regulations (FHMR). With the formation of the Louisiana State Police (LSP) Motor Carrier Safety Unit (MCSU), the State agreed to strict requirements established by the USDOT for the inspection of commercial motor vehicles and drivers and for the reporting of all applicable data generated from these inspections.

The primary objective of Louisiana’s MCSU was to reduce the number and severity of commercial motor vehicle crashes within the State. To facilitate this objective the LSP launched a program of roadside safety inspections, compliance reviews and educational outreach initiatives.

Only officers certified by the FMCSA may enforce the FMCSR and the FHMR.

MCSU - Operations

As part of the LSP Commercial Vehicle Enforcement Division (CVED), the MCSU is further sub-divided into three regional units and an administrative support unit. Organizationally, the MCSU parallels the general organizational structure of the LSP. The unit is staffed full time by 46 commissioned State Troopers, Sergeants, and Lieutenants. Additionally, the MCSU's efforts are being supplemented by commissioned Troopers from the LSP Towing & Recovery and HAZMAT Units.

MCSU - Technology

The use of mobile data terminals (MDTs) and Aspen software for documentation of roadside inspections enables the rapid upload of inspection data to the Federal Motor Carrier Safety Administration’s Safety and Fitness Electronics Records (SAFER) System. Upon completion of an inspection, officers transmit the data wirelessly to the Department of Public Safety Data Processing Center for immediate upload to SAFER. MCSU inspection officers anywhere in the Nation may access the SAFER System and view any inspection data uploaded to SAFER during the previous 45 days. Such technology allows officers to apprehend violators of out-of-service orders and to identify repeat offenders.

MCSU - Public Outreach

The LSP MCSU has long recognized the importance and effectiveness of comprehensive educational initiatives. The LSP, the Louisiana Highway Safety Commission, the Louisiana Motor Transport Association, and the Louisiana Forestry Association often work together to enhance the knowledge of industry and to promote highway safety. Federal programs such as ‘No-Zone’, ‘Be Ready Be Buckled’, and ‘Share the Road’ have been integral components of the LSP MCSU’s efforts.
