CSA 2010 is FMCSA's revised enforcement policy that uses a Safety Measurement System (SMS) to score carriers based on their safety performance in seven Behavior Analysis and Safety Improvement Categories (BASICs) using 24 months of data. BASIC scores are based on the recency and severity of violations and crashes, with more recent incidents weighted more heavily. Carriers can check their safety data and scores, and challenge any inaccuracies through DataQs to improve their scores. Preparing drivers and revising safety policies can help carriers improve their scores under CSA 2010.
