If you operate a commercial motor vehicle, the FMCSA is watching your safety data. The Compliance, Safety, Accountability (CSA) program is how they do it — and your scores in this system have real consequences for your business.

What CSA actually is

CSA is the FMCSA's safety compliance and enforcement program. It uses data from roadside inspections, crash reports, and investigations to evaluate motor carrier and driver safety performance. The data is processed through the Safety Measurement System (SMS), which generates scores across seven categories called BASICs.

The 7 BASIC categories

  • Unsafe driving — speeding, reckless driving, improper lane changes, texting
  • Crash indicator — crash history and patterns
  • Hours of service compliance — HOS violations from inspections and ELD data
  • Vehicle maintenance — brake, light, and other mechanical violations
  • Controlled substances / alcohol — drug and alcohol violations
  • Hazardous materials compliance — hazmat-specific violations
  • Driver fitness — licensing, medical certificates, and qualification

Each BASIC is scored as a percentile (0-100) comparing you against similar carriers. A higher number is worse — it means you have more violations than your peers. Scores above the intervention threshold (which varies by BASIC) can trigger warning letters, investigations, or enforcement actions.

How scores are calculated

Your CSA scores come from roadside inspections and crash reports over the most recent 24 months. More recent violations are weighted more heavily than older ones. The severity of each violation matters too — an out-of-service violation counts more than a minor paperwork issue.

Here's what makes it tricky: your score is relative. You're compared against a peer group of similarly sized carriers. So even if your absolute number of violations is low, if your peers are cleaner, your percentile could still be high.

Why it matters for insurance

Insurance carriers check your CSA scores when pricing your policy and at every renewal. High scores — especially in unsafe driving and crash indicator — directly increase your premium. Some carriers have hard cutoffs: if your score exceeds a certain percentile, they won't write you at all.

Poor CSA scores also affect your ability to get loads. Many brokers and shippers check SMS data before booking a carrier. A high score can cost you freight, which costs you revenue.

What you can do about it

First, check your scores regularly at ai.fmcsa.dot.gov/sms/. Know where you stand.

Second, challenge inaccurate data. If an inspection result contains errors, you can file a DataQ challenge through the FMCSA website. Correcting a single incorrect violation can significantly improve your score.

Third, focus on the BASICs where you're closest to the intervention threshold. If your vehicle maintenance score is high, invest in a stronger pre-trip inspection program. If hours of service is the issue, review your ELD compliance procedures.
