FMCSA’s safety evaluation program, CSA looks at the performance of motor carriers in seven BASICs (Behavior Analysis and Safety Improvement Categories) and compares that performance to similar carriers, using an algorithm in the Safety Management System (SMS). A similar algorithm is used to assign motor carriers scores under FMCSA’s Inspection Selection System (ISS), which advises states as to which CMVs might be pulled into a weigh station for inspection.
