What Is the CSA Program?
The Compliance, Safety, Accountability (CSA) program is the FMCSA's data-driven system for identifying and prioritizing motor carriers and drivers with safety problems. Launched in 2010 as a replacement for the older SafeStat system, CSA uses data from roadside inspections, crash reports, and compliance investigations to assign safety scores to every carrier operating in the United States.
The core of CSA is the Safety Measurement System (SMS), which organizes violations into seven categories called BASICs (Behavior Analysis and Safety Improvement Categories). Each violation receives a severity weight based on its seriousness, and these weighted scores are compared against similar carriers to produce percentile rankings that determine whether FMCSA takes enforcement action.
CSA affects every aspect of a carrier's operations: insurance rates, broker and shipper willingness to work with you, driver recruitment, and ultimately your ability to keep your operating authority. For owner-operators with small fleets, even a single bad inspection can dramatically change your BASIC percentiles.
The 7 BASIC Categories
Every CSA violation falls into one of seven BASIC categories. Each category is scored and ranked independently, meaning a carrier can have excellent scores in some BASICs and poor scores in others. Here are all seven with their intervention thresholds:
1. Unsafe Driving
Threshold: 65%Covers violations related to dangerous driving behaviors observed during roadside inspections or documented in crash reports. Common violations include speeding (5-10 severity points depending on how far over the limit), improper lane changes (5 points), following too closely (5 points), texting or cell phone use (10 points), and reckless driving (10 points). This is one of the most closely watched BASICs because it directly correlates with crash risk.
2. Hours-of-Service (HOS) Compliance
Threshold: 65%Tracks violations of hours-of-service regulations. Common violations include driving beyond the 11-hour limit (7 points), exceeding the 14-hour window (7 points), insufficient off-duty time (7 points), false or missing log entries (5 points), and ELD violations (1-5 points depending on type). Fatigue-related crashes make HOS compliance a high priority for FMCSA enforcement.
3. Driver Fitness
Threshold: 80%Covers driver qualification requirements. Violations include operating without a valid CDL (10 points), operating without proper endorsements (4 points), expired or missing medical certificate (4 points), and failure to maintain driver qualification files (2 points). This BASIC has a higher intervention threshold (80%) because it is considered a lower direct crash risk factor.
4. Controlled Substances / Alcohol
Threshold: 80%Tracks drug and alcohol violations. These include possession or use of controlled substances (10 points), operating under the influence (10 points), and violations related to FMCSA Drug & Alcohol Clearinghouse requirements (varies). Even a single violation in this BASIC carries extreme severity and can trigger immediate investigation. Drug and alcohol violations also result in CDL disqualification under separate federal rules.
5. Vehicle Maintenance
Threshold: 80%Covers mechanical condition of the vehicle. Common violations include brake adjustment issues (4-8 points depending on severity), tire violations (8 points for flat or missing), lighting violations (1-3 points), cargo securement violations (3-7 points), and frame cracks (6 points). This is the most common BASIC for violations because every roadside inspection includes a vehicle check.
6. Hazardous Materials (HM) Compliance
Threshold: 80%Applies only to carriers transporting hazardous materials. Violations include incorrect placarding (4 points), improper shipping papers (2-4 points), leaking containers (8 points), and failure to follow HM routing requirements (4 points). If you do not haul hazmat, this BASIC will not appear on your SMS profile.
7. Crash Indicator
Threshold: 65%Tracks DOT-reportable crashes (crashes involving a fatality, an injury requiring medical treatment away from the scene, or a towed vehicle). Each crash receives a severity weight based on outcome: fatal crash (10 points), injury crash (8 points), and tow-away crash (2 points). Note that the Crash Indicator does not consider fault — all reportable crashes count, even if the carrier or driver was not at fault. This is a controversial aspect of the CSA system that the FMCSA has been reviewing.
Severity Weights & Point Calculation
Each violation in a roadside inspection receives a severity weight from 1 to 10, with 10 being the most serious. Here are the most common violations and their severity weights across key BASICs:
| Violation | BASIC Category | Severity Weight |
|---|---|---|
| Speeding 1-10 MPH over limit | Unsafe Driving | 5 |
| Speeding 11-14 MPH over limit | Unsafe Driving | 7 |
| Speeding 15+ MPH over limit | Unsafe Driving | 10 |
| Texting while driving | Unsafe Driving | 10 |
| Following too closely | Unsafe Driving | 5 |
| Driving beyond 11-hour limit | HOS Compliance | 7 |
| False log entry | HOS Compliance | 5 |
| Brake out of adjustment (20%+) | Vehicle Maintenance | 6 |
| Flat tire / tire fabric exposed | Vehicle Maintenance | 8 |
| Operating without valid CDL | Driver Fitness | 10 |
Multiple Violations Per Inspection
Time Weights & How Scores Age
The FMCSA applies time weights to violations so that recent safety performance counts more heavily than older data. This system rewards carriers who improve their safety practices over time:
| Violation Age | Time Weight | Impact Example (10-Point Violation) |
|---|---|---|
| 0-6 months | 3x | 10 severity x 3 time weight = 30 weighted points |
| 6-12 months | 2x | 10 severity x 2 time weight = 20 weighted points |
| 12-24 months | 1x | 10 severity x 1 time weight = 10 weighted points |
| 24+ months | Removed | Violation drops off SMS entirely |
The practical implication is that a brand-new violation has triple the scoring impact of the same violation 18 months later. This creates a strong incentive to avoid new violations — your score will naturally improve as older violations age down and eventually drop off. For a deeper look at violation timing, see our CSA violation duration guide.
The 6-Month Sweet Spot
Percentile Rankings Explained
Your raw severity points are not what triggers FMCSA action — your percentile ranking does. The FMCSA compares your carrier's violation scores against all other carriers in a similar safety event group (based on the number of inspections). Your percentile represents what percentage of similar carriers have better scores than you.
0-50th percentile — Your safety performance is in the better half of carriers. No FMCSA action. Brokers and shippers view this favorably. Insurance companies offer the best rates.
50-65th percentile — Above average violation rates. No formal FMCSA action yet, but you are approaching the alert zone. Some brokers and shippers may begin flagging your carrier. Focus on reducing violations.
65-80th percentile — Alert zone for Unsafe Driving, HOS Compliance, and Crash Indicator BASICs. FMCSA may issue warning letters and begin monitoring your carrier. Insurance companies will likely increase premiums. Some brokers will not work with carriers in this range.
80-100th percentile — Critical zone. FMCSA intervention is likely, including on-site compliance reviews, comprehensive investigations, and potential enforcement actions up to and including an out-of-service order. Insurance may become extremely difficult to obtain. Most reputable brokers and shippers will refuse to work with your carrier.
Small Carriers Are More Volatile
FMCSA Intervention Steps
When a carrier exceeds the intervention threshold in one or more BASICs, the FMCSA follows a progressive enforcement approach:
Step 1: Warning Letter
The FMCSA sends a letter notifying the carrier that one or more BASICs exceed the intervention threshold. The letter identifies the specific BASIC categories and encourages the carrier to take corrective action. No penalties are attached to the warning letter itself, but it signals that your carrier is on FMCSA's radar.
Step 2: Off-Site Investigation
If scores do not improve, FMCSA may conduct an off-site investigation where they request documentation from the carrier — driver qualification files, maintenance records, HOS logs, drug testing records, and other compliance documentation. Failure to respond or provide adequate documentation can escalate the investigation.
Step 3: On-Site Compliance Review
An FMCSA investigator visits your place of business to review records, inspect vehicles, and interview personnel. The investigator evaluates your overall safety management controls. The result is a safety rating: Satisfactory, Conditional, or Unsatisfactory. A Conditional rating requires corrective action within a specified timeframe. An Unsatisfactory rating can result in an out-of-service order.
Step 4: Out-of-Service Order
In the most severe cases, the FMCSA can issue an out-of-service order that immediately prohibits the carrier from operating. This effectively shuts down your business until the safety deficiencies are corrected and the order is lifted. Getting an OOS order reversed requires demonstrating that you have implemented corrective actions and can operate safely.
How to Check Your CSA Score
Monitoring your CSA scores regularly is essential for catching problems early. Here is how to access your data:
FMCSA SMS Website — Visit ai.fmcsa.dot.gov/SMS and enter your DOT number. The public can see whether your BASICs exceed thresholds, but only carriers logged in with their FMCSA portal credentials can see the actual percentile numbers and detailed violation data. See our step-by-step CSA score guide for detailed instructions.
FMCSA Portal Login — Register at portal.fmcsa.dot.gov to access your full SMS profile with detailed percentile rankings, individual inspection records, and violation-level data. This is the most complete view of your CSA data.
Monthly Updates — SMS data is updated monthly, typically in the last week of each month. Set a calendar reminder to check your scores after each update so you can quickly identify and respond to any new violations.
How to Improve Your CSA Score
Improving your CSA scores requires a combination of preventing new violations and managing existing ones. Here are the most effective strategies:
Thorough pre-trip inspections — Vehicle Maintenance is the most common BASIC for violations. A disciplined pre-trip inspection that checks brakes, tires, lights, and cargo securement catches problems before inspectors do. Spending 15 minutes on a proper pre-trip can prevent thousands of dollars in CSA impact.
Challenge incorrect violations via DataQs — Review every inspection report for accuracy. If a violation was issued in error or the inspector made a factual mistake, file a DataQs challenge. Successful challenges remove violations from your CSA record entirely.
Seek clean inspections — Clean inspections (no violations found) increase your total inspection count without adding violations, which lowers your violation rate and percentile ranking. Some drivers and carriers voluntarily stop at weigh stations or request inspections at facilities known for fair, thorough inspectors.
Wait for time weight reduction — Remember that violations automatically lose scoring impact at 6 months (3x to 2x) and 12 months (2x to 1x), and drop off entirely at 24 months. Avoiding new violations while existing ones age down is the most reliable path to improvement.
Train and monitor drivers — For carriers with multiple drivers, implement a safety training program that focuses on the specific violation types appearing in your BASICs. Use telematics data to identify risky driving behaviors (speeding, hard braking, following distance) before they become CSA violations. See our CSA score improvement guide for a complete action plan.
The Clean Inspection Strategy
The Bottom Line
The CSA program is the FMCSA's primary tool for identifying carriers with safety problems, and its reach extends far beyond regulatory enforcement. Your CSA scores directly affect your insurance costs, your relationships with brokers and shippers, and your ability to recruit and retain drivers. Understanding how the scoring system works — severity weights, time weights, percentile rankings, and intervention thresholds — empowers you to take proactive steps to protect your scores.
The keys to maintaining good CSA scores are straightforward: conduct thorough pre-trip inspections, follow HOS regulations carefully, maintain safe driving habits (proper following distances, speed management), and challenge any violations that were issued in error through the DataQs process.

CSA Violations & Penalties FAQ
Common questions about CSA violations, severity weights, and carrier safety scores
How long do CSA violations stay on your record?
CSA violations remain on your Safety Measurement System (SMS) record for 24 months from the date of the roadside inspection. However, the FMCSA uses time weights that reduce the impact as violations age: violations from the most recent 6 months carry a time weight of 3 (full impact), violations 6-12 months old carry a weight of 2, and violations 12-24 months old carry a weight of 1. After 24 months, the violation drops off your SMS profile entirely. Note that your state Motor Vehicle Record (MVR) may retain the underlying traffic conviction for 3-5 years, and your PSP (Pre-Employment Screening) report retains inspection data for 3 years and crash data for 5 years.
What is the difference between CSA points and MVR points?
CSA points (technically called severity weights) are assigned by the FMCSA through the Safety Measurement System and are based on violations found during roadside inspections. They range from 1 to 10 per violation and are used to calculate your carrier's BASIC percentiles. CSA points only come from CMV (commercial motor vehicle) inspections. MVR points are assigned by your state's DMV for traffic convictions in any vehicle — commercial or personal. MVR points affect your driver's license status and insurance rates. A single speeding ticket can generate both CSA points (if from an inspection) and MVR points (from the state conviction). The two systems are separate but both matter for your career.
Can you dispute a CSA violation?
Yes. If you believe a CSA violation was issued in error, you can file a Request for Data Review (RDR) through the FMCSA's DataQs system at dataqs.fmcsa.dot.gov. Common reasons for challenges include violations that were corrected at the roadside before the inspection was complete, violations assigned to the wrong carrier, duplicate entries, or violations where the inspector made a factual error. The state that issued the inspection reviews the challenge and can modify or remove the violation. The average processing time is 45-90 days. About 30-40% of DataQs challenges result in some modification to the inspection record. See our detailed DataQs challenge process guide for step-by-step instructions.
What CSA score triggers an FMCSA investigation?
The FMCSA uses intervention thresholds based on BASIC percentile rankings. For most carriers, a BASIC percentile above 65% triggers a warning letter. A percentile above 75% may trigger additional scrutiny. The critical threshold varies by BASIC category: Unsafe Driving and HOS Compliance trigger investigation at the 65th percentile, while Vehicle Maintenance, Controlled Substances, and Driver Fitness trigger at the 80th percentile. The Crash Indicator BASIC triggers at the 65th percentile. When a carrier exceeds these thresholds, FMCSA may issue warning letters, conduct off-site investigations, perform on-site compliance reviews, or in severe cases, issue an out-of-service order that shuts down the carrier.
How do CSA violations affect insurance rates?
CSA violations have a direct and significant impact on trucking insurance premiums. Insurance companies pull carrier CSA data when underwriting policies and at renewal. A single BASIC category above the 65th percentile can increase liability insurance premiums by 10-20%. Multiple elevated BASICs can increase premiums by 25-50% or more. Some insurers will non-renew a policy if the carrier's Unsafe Driving or Crash Indicator BASIC exceeds the 75th percentile. For owner-operators, the impact is even more pronounced because a small carrier's percentile is more volatile — a single bad inspection can spike the score dramatically. The insurance cost impact typically lasts until the violations age off your SMS record (24 months), though some insurers look at 3-year trends.
