Safety Rating Categories

FMCSA assigns Satisfactory, Conditional, or Unsatisfactory ratings after compliance reviews.

Conditional ratings can limit freight contracts and insurance options.

CSA BASICs

Seven BASIC categories track violations: Unsafe Driving, HOS Compliance, Vehicle Maintenance, Controlled Substances/Alcohol, Hazardous Materials, Crash Indicator, and Driver Fitness.

Each BASIC uses time-weighted violations to benchmark carriers against peers.

Improving Scores

Implement pre-trip inspection programs, driver coaching, and document corrective actions for every violation.

Request DataQs reviews if inspections include incorrect information.

Frequently Asked Questions

Are BASIC scores public?

Most BASIC measures are visible to the public except Crash Indicator and Hazardous Materials for small carriers.
