What Is a CSA Score?

CSA stands for Compliance, Safety, Accountability. It is the FMCSA’s safety measurement system that evaluates motor carriers using roadside inspection reports, crash history, and traffic violations from the previous 24 months.

Each category receives a percentile score between 0 and 100.

Unlike many scoring systems, lower scores are better.

For example:

• A score of 20 means your company performs better than most similar carriers.
• A score of 80 means your company is performing worse than many carriers in that category and may attract additional attention from the FMCSA.

Your score changes over time as new inspections are added and older violations lose weight or eventually fall off your record.

FMCSA Compliance Categories

The FMCSA measures carriers across several safety categories.

Unsafe Driving

This includes speeding, following too closely, distracted driving, reckless driving, and improper lane changes.

Unsafe driving violations are some of the most serious because they are closely linked to preventable crashes.

Hours of Service Compliance

This category includes:

• Logbook violations
• ELD violations
• Driving beyond legal limits
• Falsifying records

Proper hours-of-service compliance helps reduce driver fatigue and improves highway safety.

Driver Fitness

Driver fitness focuses on qualifications, including:

• Valid CDL
• Medical certificates
• Driver qualification files
• Required endorsements

Keeping driver records current helps prevent unnecessary violations.

Controlled Substances and Alcohol

This category includes drug and alcohol testing violations and Clearinghouse compliance.

Companies should have clear hiring procedures and maintain a compliant drug and alcohol testing program.

Vehicle Maintenance

Vehicle maintenance measures how well your trucks are maintained.

Common violations include:

• Brake defects
• Tire problems
• Lighting violations
• Suspension issues
• Steering defects

Routine preventive maintenance can significantly reduce these violations.

Vehicle Maintenance Driver Observed

One of the newer compliance categories focuses on driver-conducted vehicle inspections.

Drivers should perform thorough pre-trip and post-trip inspections and properly document any defects they find.

Well-documented inspections help demonstrate a strong safety culture.

Crash Indicator

This category compares your company’s crash history to similar trucking operations.

While no carrier can prevent every accident, reducing preventable crashes has one of the biggest impacts on your overall safety profile.

Why Your CSA Score Matters

Many fleet owners think their CSA score only matters to the FMCSA.

That’s no longer true.

Insurance companies regularly review CSA data when pricing commercial truck insurance. A poor safety record may lead to:

• Higher insurance premiums
• Fewer insurance options
• Increased deductibles
• More restrictive policy terms

Freight brokers also review safety records before awarding loads. A strong CSA profile can help your company qualify for more freight opportunities and build trust with customers.

Practical Ways to Lower Your CSA Score

Improving your CSA score doesn’t happen overnight, but small improvements made consistently can have a big impact.

Encourage Clean Roadside Inspections

Every clean roadside inspection helps strengthen your safety record.

Drivers should be prepared for inspections every day, not just during DOT blitz events.

A clean inspection helps offset previous violations and demonstrates ongoing compliance.

Focus on Preventive Maintenance

Many roadside violations can be prevented with regular maintenance.

Develop inspection schedules for:

• Brakes
• Tires
• Lights
• Air systems
• Suspension
• Steering components

Fixing small problems before they become violations saves money and protects your CSA score.

Improve Driver Training

Regular safety meetings and coaching can reduce violations related to speeding, distracted driving, and hours-of-service compliance.

Review inspection reports with drivers and use violations as learning opportunities instead of waiting until problems become habits.

Verify Your ELD Compliance

The FMCSA periodically removes non-compliant electronic logging devices from its approved list.

Make sure your ELD provider remains compliant and update equipment when necessary.

An outdated device can result in expensive hours-of-service violations.

Monitor Your CSA Score Monthly

The FMCSA updates carrier safety data regularly.

Review your company’s safety profile each month to identify trends before they become serious problems.

Early action is much easier than trying to recover after multiple violations.

Challenge Incorrect Violations

Mistakes happen.

If you believe an inspection or violation was recorded incorrectly, use the FMCSA’s DataQs system to request a review.

Correcting inaccurate information can improve your safety record without changing your operations.

Prioritize Your Highest-Risk Areas

Not every violation affects your company equally.

If your highest scores are in Unsafe Driving or Hours of Service Compliance, focus your safety efforts there first.

Reducing violations in these areas often provides the greatest long-term benefit.

Build a Strong Safety Culture

The safest fleets don’t simply prepare for inspections.

They build daily habits that support compliance.

Encourage drivers to:

• Complete thorough pre-trip inspections.
• Report maintenance concerns immediately.
• Follow speed limits.
• Stay within hours-of-service regulations.
• Maintain accurate records.
• Communicate safety concerns before they become larger issues.

When safety becomes part of your company culture, lower CSA scores usually follow.

The Bottom Line

Your CSA score affects far more than roadside inspections. It can influence your insurance premiums, freight opportunities, and your company’s reputation throughout the trucking industry.

The best fleets don’t wait until they receive a warning letter from the FMCSA. They actively monitor their safety performance, maintain their equipment, train their drivers, and address problems before they become violations.

Consistent attention to safety and compliance is the most effective way to lower your CSA score and keep your trucking business moving forward.
