Do brokers and shippers see my CSA score?

Yes. Brokers and shippers can access carrier safety data through the FMCSA Safety Measurement System (SMS) at safer.fmcsa.dot.gov. They see the carrier's BASIC percentile rankings, any BASIC categories flagged as above the intervention threshold, crash data, and inspection history. Many brokers use CSA data as part of carrier qualification — carriers with elevated scores in Unsafe Driving or Vehicle Maintenance may be declined setup or face additional scrutiny. Some carriers with very high CSA percentile rankings in certain BASICs are placed on carrier watch lists or declined outright.

How long do CSA violations stay on my record?

Violations remain in the SMS data for 24 months from the date of the inspection or crash. However, violations are time-weighted: violations in the most recent 6 months carry 3× the weight of violations from 7 to 12 months ago, which in turn carry 2× the weight of violations from 13 to 24 months ago. This means a string of violations from 18 months ago affects the score less than recent violations, and a clean inspection record over the next 6 months can meaningfully improve a carrier's percentile ranking.

What is a DataQ challenge and when should I use it?

DataQ is FMCSA's online system for challenging roadside inspection data that a carrier or driver believes was recorded incorrectly. Grounds for a DataQ challenge include: the violation was coded incorrectly, the vehicle or driver was not actually in your fleet, the violation description does not match the inspection report, or the violation was dismissed in court. Successful challenges remove or reduce violations from the SMS record. Carriers should review every roadside inspection report within days of receipt and file DataQ challenges promptly — there is no hard deadline, but earlier challenges are easier to document and resolve.

Can a carrier with a poor CSA score still get freight?

Yes, though it depends on the broker and the specific BASIC categories affected. Brokers who do not check CSA data during carrier setup may not flag the issue initially. However, brokers who actively check carrier safety scores — particularly in Unsafe Driving, Vehicle Maintenance, and Hours of Service — may decline to set up or tender loads to carriers above intervention thresholds. Freight contracts with shippers often include safety score requirements that are checked during the qualification process. Improving the score takes consistent clean inspections and time for older violations to age out.

CSA score explained for carriers and drivers

CSA (Compliance, Safety, Accountability) is the FMCSA system that collects roadside inspection data and crash records and turns them into percentile rankings that brokers, shippers, and regulators use to evaluate carriers. Understanding how the scoring works — and how to improve it — matters more as CSA data becomes a routine part of carrier qualification.

What CSA is and how FMCSA uses it

CSA is FMCSA's safety measurement system, replacing the older SafeStat system. It processes data from roadside inspections, investigated crashes, and compliance reviews to calculate scores for motor carriers in 7 safety categories called BASICs (Behavior Analysis and Safety Improvement Categories).

FMCSA uses CSA scores to prioritize which carriers receive on-site compliance reviews and safety investigations. Carriers above certain score thresholds in key BASICs are more likely to be targeted for inspections and investigations. FMCSA also uses crash data to identify carriers with elevated crash rates.

The public-facing SMS (Safety Measurement System) at safer.fmcsa.dot.gov allows anyone — including brokers, shippers, insurance companies, and load boards — to look up a carrier's safety scores, inspection history, crash data, and any outstanding compliance issues.

The 7 BASIC categories

1. Unsafe Driving

Speeding, reckless driving, improper lane change, failure to use a seatbelt, and similar moving violations. This BASIC has a high visibility among brokers because it directly reflects driver behavior on the road.

2. Hours of Service Compliance

HOS log violations: false logs, exceeding driving limits, missing logs, ELD violations. Carriers with HOS Compliance issues raise concerns about driver fatigue management.

3. Driver Fitness

Expired medical certificates, invalid CDL, CDL endorsement violations, operating a CMV without proper license. These are largely administrative violations — preventable with proper DQ file management.

4. Controlled Substances/Alcohol

Drug and alcohol violations during inspections or post-accident testing. This BASIC has the lowest intervention threshold because any violation is serious.

5. Vehicle Maintenance

Brake defects, tire defects, lighting violations, coupling device problems, and other equipment condition violations. This is one of the highest-frequency BASICs because mechanical defects are common inspection findings and out-of-service violations carry high point values.

6. Hazardous Materials Compliance

Placard violations, shipping paper errors, package marking defects, and other hazmat regulatory violations. Only applies to carriers hauling regulated hazardous materials.

7. Crash Indicator

Based on DOT-reportable crash data — crashes involving a fatality, injury, or a vehicle towed from the scene. FMCSA calculates a crash rate based on crash frequency and severity relative to carrier size and exposure.

How violations are scored

Each violation found during a roadside inspection is assigned a severity weight on a scale of 1 to 10, with the most serious violations (out-of-service violations, impaired driving) carrying the highest values. A brake out-of-service violation carries a higher weight than a minor documentation issue. Violations are also time-weighted:

Violations from the last 6 months: weighted at 3×
Violations from 7 to 12 months ago: weighted at 2×
Violations from 13 to 24 months ago: weighted at 1×
Violations older than 24 months: not counted

FMCSA then compares each carrier's weighted violation count against other carriers in the same size and operational category, producing a percentile ranking for each BASIC. Carriers are ranked from 0 (lowest violation rate) to 100 (highest). Carriers above the intervention threshold in a BASIC — typically 65–80% depending on the category — appear in FMCSA's monitoring queue.

What brokers and shippers actually see

The public SMS shows:

BASIC percentile rankings with visual indicators for above-threshold categories
Number of inspections and violations in each BASIC over the past 24 months
Crash data: number of crashes, crash rate, fatal/injury/tow breakdown
Authority status, insurance filings, and any active out-of-service orders

Many freight brokers run automated carrier onboarding checks that flag carriers with elevated CSA scores. Some large shippers include maximum CSA score requirements in their carrier contracts. Insurance underwriters pull CSA data as part of commercial auto underwriting — carriers with high Unsafe Driving or Vehicle Maintenance scores may face higher premiums or coverage restrictions.

Improving your CSA score

Clean inspections

Every clean inspection — one with no violations — helps. Clean inspections dilute the effect of violation-generating inspections in the percentile calculation. Drivers who regularly pass Level 1 inspections (the most thorough inspection type) with no violations build a track record that improves the carrier's standing. Seeking inspection at weigh stations when conditions are favorable (truck in good condition, hours current, paperwork complete) is one approach to accumulating clean inspection records.

Pre-trip inspections

Consistent, documented pre-trip inspections catch vehicle defects before they become roadside violations. Brakes, tires, lights, coupling devices, and conspicuity markings are the highest-frequency Vehicle Maintenance inspection findings. A driver who identifies and repairs a brake adjustment issue before dispatch is not an inspection violation; the same issue found during a roadside inspection can be an out-of-service violation worth 8 or 10 points.

Driver qualification file maintenance

Driver Fitness violations from expired medical certificates or missing DQ file items are entirely preventable. Use a tracking system with advance renewal reminders for DOT physicals (typically 24 months), annual driving record reviews, and CDL renewals. These are calendar events — missing them creates violations that would otherwise not exist.

DataQ challenges

FMCSA's DataQ system allows carriers and drivers to dispute roadside inspection violations recorded in error. Common grounds for challenges:

The violation was incorrectly coded (wrong violation code or severity level)
The vehicle or driver was not part of your operation
The violation was dismissed in court or by the jurisdiction
The inspection report contains factual errors about the vehicle or circumstances

Successful challenges remove violations from the SMS record, improving the carrier's percentile ranking. Review every inspection report within days of receipt — violations should be challenged while documentation is fresh and memories are current.

Common questions about CSA scores

Do brokers and shippers see my CSA score?: Yes. Brokers and shippers can access BASIC percentile rankings, inspection history, and crash data at safer.fmcsa.dot.gov. Many brokers check CSA data during carrier setup and before tendering loads to unfamiliar carriers. Carriers with elevated scores in Unsafe Driving or Vehicle Maintenance are often flagged or declined setup by brokers with carrier safety requirements.
How long do CSA violations stay on my record?: Violations remain in SMS data for 24 months from the date of the inspection or crash, but they are time-weighted — violations from the last 6 months carry 3× the weight of violations from 7–12 months ago. A consistent record of clean inspections over the next 6–12 months meaningfully improves a carrier's percentile ranking as older violations carry less weight and eventually age out.
What is a DataQ challenge and when should I use one?: DataQ is FMCSA's system for disputing inspection violations believed to be recorded incorrectly. File a challenge when a violation was incorrectly coded, when the vehicle or driver was not in your fleet, or when a court or jurisdiction dismissed the violation. Successful challenges remove violations from the SMS record. Review every inspection report promptly and file DataQ challenges while evidence is current.
Can I still get loads with a poor CSA score?: Possibly, though access narrows as scores rise. Brokers who do not check CSA data during setup may not flag the issue initially. Brokers with active safety screening, or shippers with contractual score requirements, may decline carriers above threshold in key BASICs. Improvement requires clean inspections consistently over time — violations age at 6-month intervals, so a focused 6–12 months of clean compliance meaningfully moves the needle.
