Abbreviation: CSA

Compliance, Safety, Accountability

FMCSA's safety measurement system that tracks carrier and driver safety performance using roadside inspection, crash, and violation data.

CSA organizes violations into BASICs (Behavioral Analysis and Safety Improvement Categories): Unsafe Driving, HOS Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials, and Crash Indicator. High BASIC scores can trigger FMCSA interventions or compliance reviews. Roadside violations affect both the carrier's and driver's CSA data.
