Compliance, Safety, Accountability Score — an initiative rolled out in December 2010 by the Federal Motor Carrier Safety Administration (FMCSA) to improve large truck safety by reducing crashes, injuries, and fatalities on the road. The score is calculated using a Safety Measurement System (SMS) based on investigations and on-road performance. SMS assesses data from seven areas called BASICs (Behavior Analysis and Safety Improvement Categories)—unsafe driving, hours-of-service compliance, driver fitness, controlled substances/alcohol, vehicle maintenance, hazardous materials compliance, and crash indicator. SMS ranks carriers based on their BASIC measure. Scores help FMCSA identify crash high-risk carriers for interventions.
