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
Licensing problems, expired medical certificates, and other driver qualification issues.
Controlled substances
Drug and alcohol testing violations, possession, or impairment.
Vehicle maintenance
Brake problems, tire issues, lighting defects, load securement failures. Caught during the vehicle portion of roadside inspections.
