A CSA score (Compliance, Safety, Accountability score) is a numerical rating system used by the Federal Motor Carrier Safety Administration (FMCSA) to measure the safety performance of commercial motor carriers and drivers. CSA scores are based on data from roadside inspections, crash reports, and investigation results β and they directly affect your ability to get freight, maintain operating authority, and obtain affordable trucking insurance.
Why Your CSA Score Matters
Your CSA score is essentially your safety reputation in the eyes of the FMCSA, shippers, and freight brokers. A high CSA score signals safety problems and triggers scrutiny β including targeted roadside inspections, compliance reviews, and in severe cases, an out-of-service order from the FMCSA. From an insurance standpoint, underwriters pull your CSA data when quoting your policy. Carriers with elevated CSA scores in key categories face higher premiums, coverage restrictions, or outright declination from standard markets.
Shippers and large brokers also screen carriers using CSA data. A high score in certain categories can disqualify you from loads, contracts, and dedicated lanes.
The 7 CSA Behavior Analysis and Safety Improvement Categories (BASICs)
The FMCSA organizes CSA violations into seven BASICs, each scored separately:
- Unsafe Driving: Speeding, reckless driving, improper lane changes, distracted driving β the category insurers watch most closely
- Hours of Service (HOS) Compliance: Violations of drive-time limits, log falsification, missing ELD records
- Driver Fitness: Invalid CDL, missing medical certificates, unqualified drivers
- Controlled Substances/Alcohol: Drug and alcohol violations β the most severe category; carriers with any violations here are immediately flagged
- Vehicle Maintenance: Brake defects, tire violations, lighting, inoperable equipment
- Hazardous Materials (HM) Compliance: Improper placarding, packaging, handling of hazmat
- Crash Indicator: Based on crash involvement weighted by severity β not all crashes are your fault, but all are counted
Each BASIC is scored on a 0β100 percentile scale relative to similar carriers. Scores above certain thresholds (typically 65β80 depending on the BASIC) trigger FMCSA intervention.
How CSA Scores Affect Trucking Insurance
When underwriters review your risk profile, CSA data is one of the first things they pull. Here’s what I see in practice at Full Coverage LLC:
- Clean CSA (all BASICs under 50%): Standard markets, competitive rates
- 1β2 BASICs elevated (50β65%): May still get standard markets but with a 10β25% premium surcharge
- Multiple BASICs elevated or Unsafe Driving over 65%: Relegated to non-standard/high-risk markets; premiums 30β60% higher
- Controlled Substances violations or Crash Indicator over 80%: Most markets will decline; very limited options remain
How to Improve Your CSA Score
CSA violations stay on your record for 24 months (most violations) and roll off naturally. In the meantime:
- Contest inaccurate violations through the FMCSA DataQs system β this is free and can remove legitimate errors
- Address vehicle maintenance proactively; brake and tire violations are among the most common and most preventable
- Implement ELD compliance and driver training programs to reduce HOS violations
- Maintain a clean pre-trip and post-trip inspection log
“CSA scores are the first thing I check before placing a new trucking account with an underwriter. A carrier with a clean safety record has 10β15 markets competing for their business. A carrier with an elevated Unsafe Driving BASIC has maybe 3β4 markets willing to write them, and the pricing difference is significant. Improving your CSA score is directly tied to improving your insurance options and rates.”

Frequently Asked Questions About CSA Scores
How do I check my CSA score?
You can view your carrier’s CSA data on the FMCSA Safety Measurement System (SMS) website at ai.fmcsa.dot.gov/SMS. Some detailed data requires a PIN number associated with your DOT number. Individual driver CSA data is tracked separately and accessible through the Pre-Employment Screening Program (PSP).
How long do CSA violations stay on my record?
Most CSA violations remain on your record for 24 months from the date of the inspection or crash. Violations from crashes that result in fatalities may stay on record longer. The FMCSA weights recent violations more heavily than older ones β violations in the past 6 months carry the most impact on your score.
Can a good CSA score lower my insurance premium?
Yes, significantly. Underwriters use CSA data as a primary factor in pricing trucking insurance. A carrier with clean BASICs and no crash indicator flags will qualify for the most competitive markets. Maintaining a strong safety record is one of the most effective long-term strategies for controlling insurance costs.
What is a DataQs challenge and how does it work?
DataQs (Data Quality system) is the FMCSA’s process for challenging inaccurate or incorrect violations on your CSA record. If you receive a roadside inspection violation that you believe was issued in error, you can submit a challenge through the FMCSA’s DataQs website. If upheld, the violation is removed from your record, which can improve your BASIC scores.
