How CSA Scores Make Your Insurance 40% More Expensive
Bottom Line Up Front
Bad CSA scores can increase your truck insurance by 20-40%. That means $2,000-$5,000 extra per year. The good news: improving your scores can save you thousands, and you can challenge incorrect violations through the DataQ process.
What Are CSA Scores and Why Do Insurers Care?
CSA (Compliance, Safety, Accountability) is FMCSA's system for tracking carrier safety performance. Your scores are based on roadside inspections, crash reports, and investigation results over 24 months.
Insurance companies check your CSA scores before quoting. High scores (bad) signal risk. Low scores (good) signal a safe operation. It is that simple.

| Vehicle Maintenance | HIGH — brake, tire, light violations | 80th percentile |
| HOS Compliance | MEDIUM — hours of service violations | 65th percentile |
| Controlled Substances | MEDIUM — drug/alcohol violations | 80th percentile |
| Driver Fitness | LOW-MEDIUM — CDL, medical cert | 80th percentile |

How to Improve Your CSA Scores
- Pre-trip inspections daily — catch brake, tire, light issues before DOT does
- Challenge incorrect violations via DataQ — up to 30% of violations have errors
- Train drivers on HOS compliance — ELD helps but driver awareness matters
- Preventive maintenance program — scheduled service prevents roadside failures
- Monitor scores monthly — use FMCSA SMS portal at ai.fmcsa.dot.gov
The DataQ Challenge Process
If you believe a violation on your record is incorrect, you can challenge it:
- Go to dataqs.fmcsa.dot.gov
- File a Request for Data Review (RDR)
- Provide evidence: photos, maintenance records, ELD data
- The reporting state reviews within 60-90 days
- If successful, the violation is removed from your CSA scores
Success rate varies by violation type, but well-documented challenges succeed 40-60% of the time.
