Driver Safety Measurement System (DSMS) Methodology

The Driver Safety Measurement System (DSMS) is a tool that is built from many of the design components of the carrier-based Safety Measurement System (SMS). The DSMS does not generate or issue driver safety ratings or “scores.” It does not affect a driver’s commercial driver’s license (CDL), or a carrier’s safety rating, which is subject to 49 CFR Part 385 of the Safety Fitness Procedures. DSMS results are not available to motor carriers, drivers, third-party providers, or the public. DSMS results are only available to enforcement officials for examining commercial motor vehicle (CMV) driver performance as part of Compliance, Safety, Accountability (CSA) investigations. Enforcement users should not draw conclusions about a driver’s overall safety condition solely based on DSMS results. However, the raw safety information from roadside inspections and crashes that feeds the DSMS is compiled by the same system that provides CMV driver-based data to the Federal Motor Carrier Safety Administration’s (FMCSA) Pre-Employment Screening Program (PSP). This program allows motor carriers to access driver inspection and crash records electronically as a part of the hiring process.
