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%.
