How are the Carrier Safety Measurement System (CSMS) scores calculated? How often will it be updated and how far back do violations count?
Under CSA 2010, SMS will replace the Safety Status (SafeStat) measurement system as FMCSA’s assessment tool to identify high-risk motor carriers requiring interventions to improve safety on our nation’s roads. SMS will evaluate the safety of individual motor carriers by considering all safety-based roadside inspection violations, not just out-of service violations as today, as well as State-reported crashes, using 24 months of performance data. SMS will assess each carrier’s safety performance in each of the seven Behavior Analysis and Safety Improvement Categories (BASICs). The SMS calculates a measure for each BASIC by combining the time and severity weighted violations/crashes (more recent violations are weighted more heavily) normalized by exposure (e.g., number of power units (PUs) OR number of relevant inspections). Applying a similar approach to that used in SafeStat, the SMS converts each carrier’s BASIC measures into percentiles based on rank relative to peers. SMS will be upd
