In FY 2008, Federal and State enforcement personnel conducted 14,906 compliance reviews (CRs) on individual motor carriers. It is intended that through education, heightened safety regulation awareness, and the enforcement effects of the CR, carriers will improve the safety of their commercial vehicle operations and, ultimately, reduce the number and severity of crashes in which they are involved. The CR Effectiveness Model measures the direct impact of compliance reviews on carriers that received CRs but not the "deterrent" effects (i.e., the "threat" of having a CR) on carriers that did not...

In FY 2007, Federal and State enforcement personnel conducted more than 15,000 CRs on individual motor carriers. It is intended that through education, heightened safety regulation awareness, and the enforcement effects of the CR, carriers will improve the safety of their commercial vehicle operations and, ultimately, reduce the number and severity of crashes in which they are involved. The CR Effectiveness Model measures the direct impact of compliance reviews on carriers that received CRs. The model is based on the individual and cumulative "before and after" changes in the safety...

Under sponsorship from the U.S. Department of Transportation Federal Motor Carrier Safety Administration, Office of Bus and Truck Standards and Operations, the John A. Volpe National Transportation Systems Center performed a preliminary research study designed to review English proficiency in relation to safe CMV operation. The study endeavored to learn: 1) The tasks CMV drivers perform that require language comprehension in the interest of safety. 2) The extent to which selected Federal and State enforcement personnel, motor carrier industry groups, individual motor carriers and drivers,...

The study was conducted in two phases. Phase 1 compares the safety performance of agricultural and nonagricultural carriers for the period 2005 through 2008, and also examines two additional industries: livestock and utility carriers, whose operations were not exempt from Hours Of Service (HOS) regulations prior to the 2005 passage of SAFETEA-LU. The Phase 1 analysis used carrier registration, inspection, and crash data from the Motor Carrier Management Information System (MCMIS). For the Phase 2 analysis, inspection data of agricultural commodity and utility carriers was collected during an...

This final report updates the results of a July 2004 report that was prepared in response to Section 222(d) of the Motor Carrier Safety Improvement Act of 1999 (MCSIA). Section 222(d) of the Act required the Secretary of Transportation to conduct a study of the effectiveness of the revised civil penalties established in the Transportation Equity Act for the 21st Century (TEA-21) in ensuring prompt and sustained compliance with Federal motor carrier safety and commercial driver's license laws. The 2004 study focused primarily on the impact of the changes in the revised civil penalty schedule...
