How Your CSA Scores Secretly Raise Your Insurance Rates
Do Insurance Companies Really Check Your CSA Scores?
Yes — every single time. Before issuing a quote, insurance underwriters pull your CSA (Compliance, Safety, Accountability) scores from FMCSA's Safety Measurement System. High scores in any BASIC category signal higher risk, which directly translates to higher premiums. Most truckers don't realize their CSA data is being used against them on every renewal.
Which BASICs Affect Insurance Rates the Most?
FMCSA tracks 7 BASIC categories, but insurance companies weight them differently:
| BASIC Category | Impact on Insurance | Rate Increase |
|---|---|---|
| Unsafe Driving | Highest impact | 20-50% surcharge |
| Crash Indicator | Highest impact | 25-60% surcharge |
| HOS Compliance | High impact | 10-25% surcharge |
| Vehicle Maintenance | Moderate impact | 5-15% surcharge |
| Driver Fitness | Moderate impact | 5-15% surcharge |
| Controlled Substances | High impact (if any) | Policy denial possible |
| HazMat Compliance | Moderate (if applicable) | 10-20% surcharge |
Key insight: Unsafe Driving and Crash Indicator are the two BASICs that cost you the most money on insurance. A single at-fault accident can raise your rates by $3,000-$8,000/year.
How Much Can You Save by Improving CSA Scores?
Carriers who improve their CSA percentile from the 75th (high risk) to the 25th (low risk) typically see savings of $2,000-$5,000 per year on their insurance package.
Here's a real-world example for an owner-operator with 1 truck:
| CSA Percentile | Annual Insurance Cost | Savings vs High Risk |
|---|---|---|
| 75th+ (high risk) | $14,000-$18,000 | — |
| 50th (average) | $11,000-$14,000 | $3,000-$4,000 |
| 25th or below (low risk) | $9,000-$12,000 | $5,000-$6,000 |
How Long Do Violations Stay on Your CSA Record?
Roadside inspection violations remain on your CSA record for 24 months from the inspection date. However, FMCSA applies a time-weight formula — older violations count less than recent ones. Violations in the most recent 6 months have the highest weight.
How to Improve Your CSA Scores?
- Pre-trip inspections — catch vehicle maintenance issues before an inspector does. Focus on lights, brakes, tires, and coupling devices (most common violations).
- ELD compliance — HOS violations are easily preventable with proper ELD use. Set alerts for approaching driving limits.
- Challenge invalid violations — use the FMCSA DataQs system to dispute incorrect violations. About 30% of challenged violations are removed or modified.
- Driver training — regular safety meetings reduce Unsafe Driving violations. Focus on speed, following distance, and lane changes.
- Clean inspection program — aim for clean inspections (no violations found). Each clean inspection improves your overall score.

How much do CSA scores affect my insurance rates?+
CSA scores can affect your rates by 5-60% depending on the category. Unsafe Driving and Crash Indicator have the highest impact — a carrier in the 75th percentile can pay $3,000-$6,000 more per year than one in the 25th percentile.
Can I get violations removed from my CSA record?+
Yes. Use FMCSA's DataQs system at dataqs.fmcsa.dot.gov to challenge incorrect violations. About 30% of challenged violations are removed or modified. You must file within 24 months of the inspection.
How often do insurance companies check CSA scores?+
At every policy renewal (typically annually) and when you request a new quote. Some carriers also conduct mid-term CSA reviews that can trigger rate adjustments.
Do clean inspections help lower my insurance?+
Yes. Clean inspections (no violations found) actively improve your CSA scores by lowering your violation rate. Some insurers specifically look at the ratio of clean to non-clean inspections.
