How to Improve Your CSA Score: A Practical Guide for New Carriers

CSA scores quietly shape your business. Brokers screen them. Insurance underwriters price from them. Shippers reject carriers above intervention thresholds. And FMCSA uses them to decide who gets investigated next. The good news for new carriers is that CSA percentiles are entirely controllable -- they go up or down based on your behavior on the road and your records back at the office.

Quick refresher on how CSA works

The Compliance, Safety, Accountability (CSA) program measures carriers across seven Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, HOS Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials, and Crash Indicator. Each violation receives a severity weight and a time weight, then the Safety Measurement System (SMS) compares you to similar-size carriers and assigns a percentile. Public BASICs (Unsafe Driving, HOS Compliance, Vehicle Maintenance) are visible to brokers and shippers.

Unsafe Driving BASIC -- the highest-impact area

This BASIC is driven by moving violations: speeding, lane changes, following too close, texting, seat belt, and reckless driving. Practical steps:

• Pull MVRs every year (49 CFR 391.25) and counsel drivers on any new violation
• Use in-cab cameras that capture hard braking and harsh events so you can coach before tickets happen
• Address every speeding ticket the same week -- coaching, retraining, and documentation
• Set governed road speeds at or just below the legal limit on every truck

Hours of Service Compliance BASIC

Driven by HOS violations and false logs. Most new-carrier HOS violations stem from incorrect ELD use, untrained drivers, or missed supporting documents.

• Use a registered ELD listed at csa.fmcsa.dot.gov/ELD
• Train every driver on the ELD user manual and keep it in the cab
• Audit driver logs weekly -- look for missing duty status changes, edits, and unidentified driving time
• Save six months of supporting documents per driver per month (bills of lading, fuel receipts, toll records)

Vehicle Maintenance BASIC

The single most common reason new carriers see climbing CSA percentiles. Roadside inspection violations like lights out, tire issues, brake adjustment, and exhaust leaks pile up fast.

• Pre-trip every shift, every vehicle. Document the pre-trip on the DVIR (49 CFR 396.11)
• Post-trip inspections with defect reporting and a written repair certification
• Annual inspection on every CMV (49 CFR 396.17), with the report on file
• Tire tread and pressure checks at every fuel stop
• Light, mirror, and reflector check every pre-trip -- the cheapest BASIC fix there is

Driver Fitness BASIC

Driven by license, medical card, and CDL endorsement violations.

• Verify CDL class and endorsements match the vehicle being driven
• Maintain a complete driver qualification file (49 CFR Part 391)
• Track medical card expirations in a calendar with 60-day reminders
• Run a Clearinghouse query annually and pre-employment for every CDL hire

Controlled Substances and Alcohol BASIC

Generally low risk if your testing program is real and documented. Failures show up when a driver is stopped without a valid Clearinghouse query or when the company never enrolled in a consortium.

Crash Indicator BASIC

Crashes count for two years even when not the driver's fault. The only ways to reduce this BASIC are to prevent crashes and to file DataQs challenges where the police report shows the driver was not at fault.

Use DataQs to remove bad data

DataQs (dataqs.fmcsa.dot.gov) is the system for challenging inaccurate roadside inspection violations, crash data, and other MCMIS entries. If a violation was wrong -- the officer cited the wrong CFR, the inspection was duplicate, the crash report shows you were not at fault -- file a Request for Data Review with the supporting document. Successful challenges remove the entry from your SMS calculation.

Coach drivers, do not just write them up

Behavioral change is the lever that moves CSA. After every roadside violation, sit down with the driver, review the violation, identify the cause, and document the corrective action -- retraining, route change, fatigue management, vehicle assignment change. Keep the documentation in the driver file. It both reduces the next violation and builds the safety record an auditor wants to see.

Run a quarterly CSA self-review

Pull your SMS report every 90 days. Identify the BASIC with the highest percentile and pick three concrete moves to push it down next quarter. Repeat. Over a year, focused attention pulls percentiles back below intervention thresholds.

How ClearToHaul helps

Monthly Compliance Management includes CSA score monitoring with quarterly compliance calls so you know which BASIC is climbing and exactly what to do about it before brokers or insurance underwriters notice.
