On Tuesday, February 14, 2023, the Federal Motor Carrier Safety Administration published a notice requesting comments on proposed changes to the Compliance, Safety, Accountability (CSA) system. The notice comes in response to recommendations from the National Academy of Sciences’ that FMCSA adopt the Item Response Theory (IRT) model to prioritize carriers for safety intervention. Ultimately, FMCSA has concluded that it will not adopt IRT. Instead it is proposing modifying CSA’s Safety Measurement System (SMS) to better calibrate motor carrier scores to more accurately assess carrier’s compliance posture and crash risk. Read STC’s summary of FMCSA’s proposal.
