How are the Safety Measurement System (SMS) scores calculated? How often will it be updated and how far back do violations count?
When CSA 2010 is implemented, SMS will replace the Safety Status (SafeStat) measurement system as FMCSA’s tool to identify high-risk motor carriers requiring interventions in order to improve safety on the 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 well as State-reported crashes, using 24 months of performance data. SMS will assess each carrier’s safety performance in each of the Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, Fatigued Driving (Hours-of-Service), Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Cargo-Related, and Crash Indicator. 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 or number of relevant inspections).
