How to Resolve a Poor CSA Score

A CSA score reflects a carrier’s safety performance across roadside inspections, crash history, and compliance records. When that score climbs higher than it should — whether due to accumulated violations or data recorded in error — it can affect carrier relationships, insurance rates, and FMCSA oversight activity.

This article covers two distinct situations: carriers looking to improve a score through better operational practices, and carriers dealing with violations they believe were recorded incorrectly. Both require a different approach, and both are worth understanding before a score moves further in the wrong direction.

What follows is a breakdown of how CSA scores are affected, what carriers can do to bring a score down over time, and how to use the FMCSA’s DataQs system to challenge data that does not accurately reflect a carrier’s record.

How CSA Scores Are Affected

CSA scores are calculated on a percentile scale from 0 to 100. A lower percentile is better — carriers with lower scores have a stronger safety record relative to peers in the same category. Scores that climb into thresholds set by the FMCSA can trigger additional oversight, including investigations and interventions.

Three factors affect a CSA score most directly:

Violations are the most frequent contributor. Each infraction recorded during a roadside inspection carries a point value based on its estimated crash risk, and more recent violations are weighted more heavily than older ones. For a detailed breakdown of the most common violations and their point values, see 10 Common CSA Violations and How to Avoid Them.

Crashes are factored into a carrier’s score through the Crash Indicator BASIC. Regulations updated in 2010 introduced the Crash Preventability Determination Program, which allows carriers to challenge whether a crash should be counted against them based on fault. A crash determined to be non-preventable may be removed from the calculation.

CDL suspensions carry significant scoring consequences. A suspended license — regardless of the reason — affects the Driver Fitness BASIC and can move a carrier’s percentile substantially. Keeping CDL credentials current across the full driver roster is one of the more straightforward ways to avoid this category of score impact.

The FMCSA organizes all violations into seven Behavior Analysis and Safety Improvement Categories, or BASICs. For a full review of each category and the violations that fall under them, the 10 Common CSA Violations article covers each one in detail.

CSA Intervention Thresholds

Each BASIC category has an intervention threshold — a percentile level at which the FMCSA may flag a carrier for further scrutiny, beginning with a warning letter and potentially escalating to a compliance review or roadside inspection targeting. Thresholds vary by both BASIC category and carrier type, with higher-risk categories and higher-stakes carrier types held to stricter standards.

The current thresholds under the existing SMS methodology are:

Exceeding a threshold does not result in automatic penalties — it flags the carrier for potential intervention. A warning letter is typically the first step. Carriers that remain above threshold or exceed thresholds in multiple categories face escalating enforcement attention.

A note on upcoming changes: The FMCSA is currently overhauling the SMS methodology. Proposed changes include renaming the BASIC categories, consolidating similar violations, splitting Vehicle Maintenance into two separate categories, and adjusting several intervention thresholds. As of April 2026, these changes are still under review and have not been fully implemented. Carriers can preview their scores under the proposed new methodology at the FMCSA CSA Prioritization Preview site.

How to Check Your CSA Score

Carriers can check their CSA score at any time through the FMCSA Safety Measurement System at ai.fmcsa.dot.gov/SMS. Enter your USDOT number to view your current percentile rankings across all BASIC categories. A PIN is required to access your full profile — if you do not have one, you can request it through the CSA portal and it will be sent within 4 to 7 days. SMS data is updated monthly, so scores reflect the most recent 24-month rolling window of inspection and crash data.

How to Improve Your CSA Score

Improving a CSA score is a process that plays out over time. Violations remain on record for 24 months, and more recent infractions carry more weight than older ones, which means a consistent run of clean inspections is the most reliable path back to a lower percentile. There is no shortcut, but there are specific practices that make a meaningful difference.

Monitor SMS data monthly. The FMCSA’s Safety Measurement System updates carrier data on a regular schedule. Reviewing it at least once a month allows carriers to catch new violations quickly, identify patterns across BASIC categories, and prioritize which issues need the most immediate attention. A pattern of lamp violations, for example, points to a pre-trip inspection gap rather than an isolated incident. Tracking performance metrics across the fleet alongside SMS data gives carriers a more complete picture of where compliance risks are developing. See Carrier Performance Metrics for guidance on building that kind of visibility.

Build and use a pre-trip inspection checklist. The violations that accumulate most frequently — lighting, tires, cargo securement, windshield condition — are the same ones a thorough pre-trip inspection catches before a run begins. Carriers with documented inspection routines are also better positioned during audits, as records demonstrate a proactive compliance culture rather than a reactive one.

Audit ELD data regularly. Hours-of-service violations often surface in patterns rather than isolated incidents. Regular audits of Electronic Logging Device data give carriers visibility into compliance gaps before they appear at a roadside inspection. It is also worth noting that excessive driver wait times at facilities can create pressure on hours-of-service compliance — detention that eats into available drive time is a contributing factor in HOS violations that often goes unaddressed at the fleet level.

Track CDL expiration dates across the full roster. An expired CDL is an 8-point Driver Fitness violation and one of the more preventable entries on a carrier’s record. Maintaining a renewal calendar with advance reminders for every driver eliminates this category of violation almost entirely.

Address maintenance citations systematically. Carriers who receive multiple vehicle maintenance violations in a short period should treat that as a process signal rather than a run of bad luck. Spot-checks, scheduled maintenance reviews, and clear repair documentation all reduce the likelihood of repeat citations in the same category.

Keep HOS regulations and hands-free requirements current. FMCSA guidelines on distracted driving and hours of service are not static — rules and enforcement priorities shift over time. Drivers and fleet managers should stay familiar with current standards rather than assuming the rules they learned during onboarding still apply in full.

How to Challenge Violations Through DataQs

When a violation appears on a carrier’s record that does not accurately reflect what occurred, the FMCSA’s DataQs system provides a formal process to request a review. Challenges filed through DataQs are known as Requests for Data Review, or RDRs. If a challenge is successful, the violation is removed from the record or reduced in severity, and the correction is reflected in the Safety Measurement System and Pre-Employment Screening Program within approximately 10 days of the next monthly data snapshot.

In 2024, DataQs processed more than 71,000 requests. Violation challenges are the most common type of submission and also the least successful — according to FMCSA data, roughly 39% of violation challenges result in a correction. That figure reflects the full range of submissions, including cases filed without strong supporting documentation. Carriers who file promptly and with thorough evidence tend to see better outcomes.

File as early as possible. Carriers technically have up to three years to challenge a roadside inspection violation and up to five years to challenge a crash record. In practice, filing within 30 days gives the best results — evidence is fresher, documentation is easier to locate, and the inspection is more likely to be accurately recalled by all parties involved.

Build a strong evidentiary record. Documentation is the most important factor in a successful challenge. Useful evidence includes maintenance records, driver logs, ELD data, dash-cam footage, photos taken at the scene during the inspection, and any notes made by the inspecting officer. If a citation was subsequently dismissed in court or a driver was convicted of a lesser charge, that outcome is among the strongest grounds for removal and should be submitted with the RDR.

Be thorough and professional in the submission. The DataQs form asks for the inspection report number, issuing state, date of inspection, and a clear explanation of why the data is believed to be incorrect. Reviewers read a high volume of submissions — concise, factual, well-documented requests move through the process more efficiently than vague or incomplete ones.

Respond promptly to follow-up requests. During the review process, the FMCSA or the reviewing state agency may request additional information. Failing to respond within 14 days can result in the case being closed. While closed cases can be reopened if the requested information is subsequently provided, responding within the initial window is the more reliable approach.

Understand the new review structure. In April 2026, the FMCSA published a significant overhaul of the DataQs program, introducing a mandatory three-stage independent review process that all states must implement by September 2026. Under the new system, initial reviews must be completed within 21 days, reconsideration decisions within 21 days, and final reviews within 45 days. Critically, the issuing officer will no longer serve as the sole decision-maker when a correction is denied — each stage requires an independent reviewer not involved in the prior decision. Until September 2026, the current DataQs process remains in effect, but carriers filing challenges now should be aware that the landscape is changing in their favor.

Stay on Top of Your Score

Bringing a CSA score down takes time, but the path is straightforward: reduce new violations through consistent pre-trip routines and fleet management practices, monitor FMCSA SMS data monthly to catch issues early, and challenge any violations that do not accurately reflect what occurred. Older infractions lose weight over time, and a steady record of clean inspections is what moves the percentile in the right direction.
