CSA Score Impact Estimator
See What a Violation Does to Your BASIC Before It's Too Late. Estimate how a roadside violation affects your FMCSA Safety Measurement System (SMS) percentile.
Estimates only — actual CSA scores are calculated by FMCSA using DataQ-verified violation records, time-weighted scoring, and peer group comparisons that this tool cannot replicate. Always verify your official SMS scores at ai.fmcsa.dot.gov/SMS.
Violation Details
Find your current BASIC scores at ai.fmcsa.dot.gov/SMS using your USDOT number.
Each BASIC has a different intervention threshold. Controlled Substances (50%) and Unsafe Driving (65%) have lower thresholds.
FMCSA assigns each violation a severity weight from 1 (minor) to 10 (critical). Find exact weights in the FMCSA SMS Violation Severity Table.
Carriers with fewer inspections experience larger percentile swings — a single OOS violation can move a small carrier 20–40 percentile points.
