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
