What are BASIC scores?
FMCSA tracks carrier performance through its Safety Measurement System (SMS), which scores carriers across six categories called BASICs. Each score is a percentile from 0 to 100, based on inspection and crash data from the past 24 months.
A score of 65 means the carrier performed worse than 65% of its peers. Anything above 75% can trigger FMCSA alerts or investigations. Brokers vetting new carriers should pay attention to scores above 50%.
- Unsafe driving
- Speeding, reckless driving, improper lane changes, seatbelt violations. All based on what officers find during roadside inspections.
- HOS / Fatigue
- Hours-of-service violations, logbook problems, driving past the allowed limits. Fatigued driving is one of the top causes of truck crashes in the US.
- Driver fitness

- Vehicle maintenance
- Brake problems, tire issues, lighting defects, load securement failures. Caught during the vehicle portion of roadside inspections.
