Summary

To improve commercial motor vehicle safety, the Federal Motor Carrier Safety Administration (FMCSA) launched its Compliance, Safety, Accountability (CSA) program nationwide at the end of 2010. CSA is designed to target unsafe motor carriers through enforcement interventions such as roadside inspections and on-site reviews. To identify carriers that pose safety risks, FMCSA implemented the Carrier Safety Measurement System, which draws on State and carrier data on carriers’ on-road safety performance.

While FMCSA has strengthened its controls to improve the quality of State-reported data used to assess carriers’ safety performance, the Agency has not fully implemented planned improvements to its processes for reviewing data correction requests and for ensuring that carriers submit accurate information. In addition, FMCSA has not fully implemented the CSA enforcement intervention process nationwide; at the time of our report, only 10 States had fully implemented CSA enforcement interventions. Finally, FMCSA has limited documentation demonstrating it followed information technology best practices and Federal guidance for its Carrier Safety Measurement System. FMCSA concurred with all six of our recommendations to strengthen CSA.
