I want to start with the opinion that shapes everything else I’m about to say: if your primary focus is on moving your CSA scores, you’re already thinking about this wrong.
Scores are a lagging indicator. They reflect what happened in your operation over the past 24 months. Carriers who chase the number — obsessing over percentile rankings without addressing the underlying behaviors — end up frustrated. The number doesn’t move because you watched it. It moves because you fixed what was driving it.
I learned this in practice. When I was Senior Director of Transportation Compliance and Safety at Freeman LLC, overseeing a fleet of more than 4,400 assets, we had a Crash BASIC percentile that was well into alert territory — 82%. Within a year, we brought it down to 23%. That wasn’t accomplished by running reports. It was accomplished by changing behaviors, maintenance practices, driver accountability systems, and how we used data. The score followed.
Here’s what that process actually looks like.
How FMCSA’s SMS and the BASICs Work
Before you can move a score, you need to understand the system that generates it. FMCSA’s Safety Measurement System (SMS) groups violations from roadside inspections and crash reports into seven Behavior Analysis and Safety Improvement Categories — the BASICs:
- Unsafe Driving — speeding, reckless driving, lane change violations, seatbelt
- Hours of Service (HOS) Compliance — logbook/ELD violations, false logs, HOS limits
- Driver Fitness — invalid CDLs, medical certificate issues, out-of-service violations for driver fitness
- Controlled Substances/Alcohol — positive tests, violations at roadside
- Vehicle Maintenance — equipment violations: tires, brakes, lights, cargo securement
- Hazardous Materials Compliance — placarding, loading, handling (if applicable)
- Crash Indicator — crash history weighted by severity
Each BASIC percentile ranks your carrier against peers with similar numbers of inspections. Higher percentile = worse relative performance. Alert thresholds trigger visibility to FMCSA investigators and, importantly, to shippers and brokers who use SMS data in carrier vetting.
A few things about how the math works that many carriers miss:
SMS uses a time-weighted system — recent violations count more than older ones. A violation from 23 months ago carries less weight than one from last month. This means your score is improving the moment you stop adding violations, but it takes time to see the full effect as older data ages out.
Violations are also severity-weighted. An out-of-service (OOS) violation carries more weight than a non-OOS violation. One serious OOS finding — a brake violation that pulls a truck, for example — can have a disproportionate impact compared to several lesser violations.
Inspection quantity matters too. A carrier with few inspections has less data in the system, which can mean more volatility in percentile rankings. More inspections with clean outcomes help stabilize and improve your position.
The Practical Levers That Actually Move Scores
1. Start with DataQs — Your Data Has Errors
Before you can improve your scores, you need to know whether the data in SMS is accurate. FMCSA’s DataQs system allows carriers to challenge violations they believe were incorrectly recorded — wrong vehicle, wrong violation code, violation that was written but subsequently cleared at the scene.
This is not a back door to remove legitimate violations. It is a legitimate process to correct data errors, and data errors are more common than carriers realize. Inspectors enter data manually; mistakes happen. An incorrect violation on the wrong vehicle is inflating scores that don’t belong to you.
Action: Pull your SMS data, review every violation entry, and identify any that warrant a DataQs challenge. Work through those systematically before you benchmark where you actually stand.
2. Understand Which BASIC Is Driving Your Problem
Not all BASICs respond to the same interventions. A high Vehicle Maintenance score requires different action than a high HOS Compliance score. Identify which BASIC or BASICs are in alert or near-alert status and concentrate resources there first.
For most fleets, the highest-priority BASICs are Vehicle Maintenance and Unsafe Driving — both because they’re commonly elevated and because they’re the ones that correlate most directly with crash risk. That’s not a coincidence; they’re in alert for a reason.
3. Maintenance Discipline Is the Foundation
Vehicle Maintenance BASIC violations — tires, brakes, lighting, cargo securement — are almost entirely preventable. They come from equipment that hasn’t been inspected properly or that had defects documented but not repaired before the vehicle went back into service.
The fix isn’t complicated, but it requires discipline:
- Pre-trip and post-trip DVIRs completed every day, by every driver, for every vehicle — not as a formality but as an actual inspection
- Defects documented and repaired before the vehicle moves — a DVIR noting a defect with no corresponding repair record is a liability, not documentation
- Annual inspections completed on schedule and records retained
- A preventive maintenance program — not just reactive repairs, but scheduled service intervals for tires, brakes, lights, and other high-violation items
When I’m working with a carrier on their Vehicle Maintenance BASIC, the first thing I look at is whether DVIRs are actually being completed and whether defects are being closed out. If those two things aren’t happening consistently, everything else is secondary.
4. Driver Coaching and Accountability for Unsafe Driving
Unsafe Driving violations are behavioral — they respond to coaching, accountability, and feedback loops. Telematics gives you the data, but data without action is just expensive reporting.
An effective coaching loop reviews events on a defined schedule, delivers specific behavior-focused feedback (not general lectures), escalates repeat violations through documented corrective action, and recognizes clean performance. Coaching without documentation is also a legal exposure problem: if a driver has a repeated unsafe behavior pattern and you can’t show you addressed it, your liability in a claim grows.
5. HOS and ELD — The Gap Is Usually Policy, Not Intent
HOS violations trace to one of three sources: drivers confused about the rules, drivers pressured to run illegal, or ELD configuration issues. A written HOS policy is the baseline — trained on, not just distributed. Load planners and dispatchers need to understand HOS too, because pressure that produces violations often originates in the office, not the cab. Audit ELD records regularly for patterns before FMCSA identifies them first.
6. Time Is Part of the Equation
SMS uses a 24-month rolling window. Even if you fix every behavior today, the violations from the past two years are still in the system and still affecting your percentile. The score won’t move overnight.
What this means practically:
- Start now — every clean inspection adds to your base
- Don’t get discouraged if scores don’t move immediately after implementing changes
- Track leading indicators (violation rate per inspection, OOS rate, clean inspection percentage) rather than just watching the BASIC percentiles
- Set a 6-month and 12-month review cadence to assess progress
When we were working on the Crash BASIC at Freeman, results didn’t show up immediately in the percentile. We tracked crash rate per million miles, near-miss reports, and maintenance defect rates as our leading indicators. The BASIC percentile improvement came later, as a result of those underlying numbers moving.
Crash Indicator: The BASIC That Scares Carriers Most
The Crash Indicator draws on crash reports, not inspection violations — you can’t prevent a crash from being reported. What you can do: challenge crashes where a “not preventable” determination removes them from SMS calculations (requires documentation — police reports, witness statements, dash cam footage); reduce crash frequency through the behavioral and maintenance practices above; and review every crash internally as operational data, not just an incident to close out.
At Freeman, treating every preventable crash as a fleet learning event — not just a driver consequence — was central to the Crash BASIC improvement. Culture is a lever too.
Frequently Asked Questions
How long does it take to see CSA score improvement? It depends on your violation history and how quickly you add clean inspections to your record. The 24-month rolling window means older violations age out over time. Most carriers see meaningful movement within 6 to 12 months of consistent operational improvement — but the timeline varies based on fleet size, inspection frequency, and starting percentile.
Can I remove violations from my SMS record? Legitimate violations cannot be removed, but incorrect data can be challenged through DataQs. Crashes that are determined “not preventable” are removed from SMS calculations (though they remain in the crash register). This is why a careful DataQs review is the first step in any score improvement effort.
Which BASIC should I address first? Address whichever is in alert status — those carry the most regulatory and commercial risk. If multiple BASICs are in alert, Vehicle Maintenance and Unsafe Driving are typically where the highest leverage is.
Do shippers and brokers see my CSA scores? SMS data is publicly available, and many shippers and brokers actively check carrier scores as part of their vetting process. Alert-status BASICs can disqualify carriers from lanes and contracts. This is one of the most direct commercial consequences of elevated scores.
We have good scores now. Do we still need a compliance program? Yes. Good scores reflect past performance. A compliance program is what maintains them. Carriers who let their guard down — slowing maintenance, reducing driver accountability — typically see scores deteriorate before they notice the problem.
Fix the Behaviors. The Score Will Follow.
If your CSA scores are in alert status — or trending in the wrong direction — the answer is an operational diagnosis, not a dashboard refresh. At Logistics Assistance Now, we work with carriers to identify what’s driving their BASIC scores, build the systems to address it, and track the leading indicators that tell you whether it’s working before the percentile moves.
