CSA 2010 is FMCSA's revised enforcement policy that uses a Safety Measurement System (SMS) to identify unsafe carriers and drivers. SMS evaluates carriers based on 7 categories of safety performance for their drivers over the last 24 months. A carrier's BASIC score in each category is determined by combining the severity and recency of violations, with more recent violations weighted more heavily. Carriers should thoroughly review and potentially revise their safety policies and procedures, educate their drivers on CSA 2010 and how it affects scores, and be prepared to challenge inaccurate safety data through the DataQ process.
