Q: What Is a CSA Score and How Does It Affect Your Trucking Authority

A CSA score is a Compliance, Safety, Accountability percentile that FMCSA calculates from roadside inspection results and crash data, scoring carriers in seven BASIC categories such as Unsafe Driving, Hours-of-Service Compliance, and Vehicle Maintenance. Brokers, insurers, and FMCSA use CSA scores to identify high-risk carriers, and scores that exceed an intervention threshold can trigger warning letters, on-site investigations, or downgrades to safety rating.

If you hold a USDOT number, you have a CSA score whether you know it or not. It updates monthly, it is publicly visible to brokers and insurers, and it directly affects what loads you can book and what you pay for insurance. This guide explains how CSA actually works, what the BASICs are, and what to do when a score gets too high.

What CSA stands for

CSA stands for Compliance, Safety, Accountability. It is the FMCSA program that uses data from roadside inspections, crash reports, and investigation results to identify motor carriers most likely to have safety problems. CSA is not the same as your safety rating. The safety rating comes from a compliance review and is one of three values: Satisfactory, Conditional, or Unsatisfactory. CSA scores update monthly without a review.

The seven BASIC categories

Unsafe Driving
Speeding, reckless driving, improper lane changes, failure to use seat belt.
Hours-of-Service Compliance
Log falsification, exceeding driving limits, no log when required.
Driver Fitness
Driving without a valid CDL, medical card violations, training violations.
Controlled Substances/Alcohol
Driving under the influence, possession of controlled substances.
Vehicle Maintenance
Brake violations, lighting, tires, and other roadside equipment defects.
Hazardous Materials Compliance
Placarding, packaging, labeling and shipping paper violations -- only carriers hauling hazmat are scored.
Crash Indicator
Crash involvement weighted by severity and recency. This BASIC is not publicly displayed in percentile form for most carriers.

How a score is calculated

Each roadside violation has a severity weight (1 to 10) and a time weight that decays over a 24-month window. FMCSA totals your weighted violations in each BASIC and divides by your normalized exposure (vehicles, mileage, or inspections, depending on the BASIC). The result is compared to peer carriers of similar size and a percentile is assigned. A percentile of 80 in Unsafe Driving means your score is worse than 80 percent of peer carriers.

Intervention thresholds

Each BASIC has an intervention threshold percentile. When you cross it, FMCSA flags you for intervention. The threshold depends on the BASIC and your carrier type:

Unsafe Driving, Crash Indicator, HOS Compliance: 65 (general), 60 (passenger), 50 (hazmat)
Vehicle Maintenance, Controlled Substances/Alcohol, Hazmat Compliance: 80 (general), 75 (passenger), 65 (hazmat)
Driver Fitness: 80 (general), 75 (passenger), 65 (hazmat)

What happens when you cross a threshold

Interventions escalate from a warning letter to off-site investigations and finally to a full on-site compliance review. A compliance review can result in a Conditional or Unsatisfactory safety rating. Even without a formal intervention, scores above threshold cause broker contracts to dry up and insurance premiums to spike at renewal.

How to keep CSA scores low

Reduce roadside violations
Pre-trip inspections that actually catch defects, ELD discipline, and driver training.
Challenge incorrect violations via DataQs
Errors do happen. File a DataQ challenge promptly with documentation.
Monitor monthly
FMCSA updates scores monthly. Watch trends so you can act before crossing a threshold.
Run frequent log audits
HOS violations compound. Spot falsification or unassigned driving early.
Build a real maintenance program
Vehicle Maintenance is the easiest BASIC to fail with worn brakes, bad lights, or low tires.

Why new carriers should care from day one

CSA tracking starts the moment you have an active DOT number. A single bad inspection in your first 60 days can dominate your scores for months because you have very little exposure data to dilute it. Brokers reviewing a new carrier with one bad inspection often pass on the load entirely.

How ClearToHaul keeps your CSA clean

Monthly Compliance Management at $199 per month includes CSA score monitoring across every BASIC, quarterly compliance calls, DataQ challenge support, and ongoing audit readiness so a single inspection never spirals into an intervention.
