What is a CSA Score?

CSA (Compliance, Safety, Accountability) is FMCSA's safety measurement program that rates carriers based on inspection violations, crashes, and compliance history. Your CSA scores directly impact your ability to get loads, your insurance rates, and whether FMCSA intervenes in your operations.

The 7 BASIC Categories

CSA uses seven Behavior Analysis and Safety Improvement Categories (BASICs) to evaluate carrier safety. Each category has an intervention threshold — exceed it and FMCSA may take action. Brokers and shippers also use these thresholds to screen carriers.

Unsafe Driving

Speeding, reckless driving, improper lane changes, following too close

Intervention

65%

Common violations:

Speeding 6-10 mph overFollowing too closeTexting while driving

Hours of Service (HOS)

Violations of HOS regulations and ELD requirements

Intervention

Common violations:

Driver Fitness

Driver qualifications, medical certificates, licensing

Intervention Thresholds

When your percentile exceeds the threshold (65% or 80% depending on category), FMCSA may issue warning letters, conduct a focused investigation, require a compliance review, or propose safety rating changes. Brokers typically avoid carriers above these thresholds. For the deep dive on each category, see our 7 CSA BASIC categories guide.

How CSA Scores Work

Percentile Ranking

CSA scores are percentiles, not absolute scores. A score of 75% means you're worse than 75% of similar carriers. Lower is better — 0% means you're the safest, 100% means you're the most at-risk.

Time Weighted

Recent violations count more. Violations in the last 6 months carry 3x weight. At 6-12 months, it's 2x. After 12 months until they drop at 24 months, they're 1x weight. This rewards improving behavior.

Severity Weighted

Not all violations are equal. A tire tread violation might be 1 point. Driving while disqualified could be 10 points. Crash severity, injuries, and fatalities all carry additional weight.

Safety Event Groups

You're compared to carriers of similar size. A small carrier with 10 inspections isn't compared to a mega-carrier with 10,000. This keeps the comparison fair across fleet sizes.

Improving Your CSA Score

1

Pre-Trip Inspections

A thorough pre-trip catches issues before inspectors do. Check lights, tires, brakes, and securement every time. 90% of vehicle maintenance violations are preventable with proper pre-trips.

2

Use DataQs to Dispute Errors

Review your record regularly on the DataQs system. Many violations have errors — wrong VIN, duplicate entries, or dropped charges still showing. File DataQs for any legitimate disputes. See our DataQs challenge guide.

3

Stay Compliant with HOS

HOS violations are common and easily prevented. Use your ELD properly. Don't push limits. One 11-hour violation can hurt your score for 2 years.

4

Request Clean Inspections

When you pass an inspection with no violations, it still counts — it dilutes your violation rate. More clean inspections = lower scores. Some carriers actively seek Level 1 inspections when they're confident.

5

Driver Training & Hiring

Most CSA points come from driver behavior — speeding, HOS, securement. Invest in training. Use PSP reports in hiring to screen for problematic history before it becomes your problem.

For the complete 10-step improvement strategy, see our how to improve your CSA score guide.

Check Your Score Monthly

Your CSA scores update monthly in the SMS (Safety Measurement System). Create an account at ai.fmcsa.dot.gov/SMS to monitor your scores. Catching issues early lets you dispute errors and address problems before they cost you loads or trigger FMCSA intervention.

Bad CSA scores create a vicious cycle: high scores on the Safety Measurement System mean fewer loads and higher insurance costs, which creates financial pressure, which can lead to cutting corners, which causes more violations.

How Our Team Monitors Carrier Safety

CSA compliance is foundational to everything we do as a dispatch service. Here's how our team actively supports your safety record:

CSA monitoring before every partnership

Before dispatching for any carrier, we review their CSA scores on FMCSA SMS. We check all 7 BASIC categories, review recent inspection history, and verify authority status. This same diligence is how we verify brokers too — safety goes both ways.

Load planning that protects your safety record

We never pressure drivers to exceed HOS limits or skip pre-trip inspections. Our dispatchers plan realistic schedules that account for loading times, traffic, and weather. A $16,000 fine and CSA points aren't worth any load rate.

Proactive compliance support

We track DOT biennial updates, insurance filing deadlines, and registration renewals for every carrier we work with. A deactivated DOT number or lapsed insurance doesn't just mean no loads — it can trigger FMCSA investigation that damages your CSA profile.

CSA Score FAQ

Common questions about CSA scores and safety ratings

What is a good CSA score?

Lower is better. Scores below the intervention threshold (65-80% depending on category) are considered acceptable. A score of 0-50% in all categories is generally good. Brokers often prefer carriers with scores below 50% in critical categories like Unsafe Driving and HOS. Many top carriers maintain scores under 30%.

How is CSA score calculated?

CSA scores are percentile rankings based on violations from roadside inspections, crash reports, and investigations over a rolling 24-month period. Recent violations (0-6 months) carry 3x weight, 6-12 month violations carry 2x weight, and 12-24 month violations carry 1x weight. You're compared to carriers with similar inspection counts.

Can I dispute CSA violations?

Yes, through FMCSA's DataQs system (dataqs.fmcsa.dot.gov). You can challenge factual errors, duplicate entries, incorrect vehicle information, or violations that should have been dismissed. About 40% of DataQs requests result in changes. It's absolutely worth doing — see our DataQs challenge guide for the step-by-step process.

How long do violations stay on my CSA record?

Violations remain on your CSA record for 24 months from the violation date. After 24 months, they drop off automatically. This means consistent safe operations can quickly improve your scores. Focus on clean inspections — they dilute your violation rate.

Do brokers and shippers check CSA scores?

Yes, approximately 85% of brokers check CSA scores before booking loads. Many use automated screening that rejects carriers above certain thresholds. Shippers increasingly require carriers to maintain scores below specific percentiles. High CSA scores directly cost you revenue by disqualifying you from premium loads.

How does CSA score affect insurance rates?

Insurance companies heavily weigh CSA scores, especially Unsafe Driving and Crash Indicator categories. Carriers above intervention thresholds can see premium increases of 25-50% or face non-renewal. Improving your CSA score is one of the most effective ways to reduce insurance costs — see our CSA and insurance guide.
