How to Improve Your CSA Score in 90 Days

Your Compliance, Safety, Accountability (CSA) score directly affects your ability to book freight, your insurance premiums, and your exposure to FMCSA interventions. Carriers with elevated CSA scores in one or more BASIC categories find themselves excluded from shipper-approved carrier lists, passed over by quality brokers, and subjected to increased roadside inspections. The good news is that CSA scores can be improved significantly within 90 days if you take a systematic, data-driven approach.

Understanding Your CSA Score

The CSA Safety Measurement System evaluates carriers across seven Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, Crash Indicator, HOS Compliance, Vehicle Maintenance, Controlled Substances/Alcohol, Hazardous Materials Compliance, and Driver Fitness. Each BASIC is scored based on the number and severity of violations, weighted by how recently they occurred. Recent violations carry more weight than older ones, which means both good and bad performance has an outsized impact on your current score.

Your percentile ranking in each BASIC is compared against carriers of similar size. A percentile above the intervention threshold (which varies by BASIC) triggers FMCSA attention ranging from warning letters to compliance reviews and potential operating authority actions. Even if you are below the intervention threshold, an elevated score relative to your peers can affect your competitiveness for quality freight.

Days 1 to 14: Audit and Assess

Start by pulling your complete ISS (Inspection Selection System) report and SMS (Safety Measurement System) results from the FMCSA's SAFER system. Identify which BASICs are elevated and drill into the specific violations driving those scores. Create a spreadsheet listing every violation from the past 24 months with the date, violation code, severity weight, and driver or vehicle involved. This analysis often reveals that a small number of drivers or vehicles account for a disproportionate share of your violations.

Review each violation for accuracy. The DataQs process allows carriers to challenge inspection results that contain errors. Common challengeable errors include violations attributed to the wrong carrier, incorrect violation codes, and factual inaccuracies in the inspection report. Filing DataQs challenges for legitimately incorrect violations is one of the fastest ways to improve your score because removing even one high-severity violation can change your percentile significantly.

Days 15 to 45: Address Root Causes

With your audit complete, focus on the specific violation categories that are elevating your score. For HOS Compliance violations, implement pre-trip HOS planning that ensures drivers have adequate hours to complete assigned loads with buffer time. Install or upgrade ELD systems that provide real-time HOS alerts to dispatchers. Train drivers on proper log annotation and the correct use of sleeper berth and personal conveyance provisions.

For Vehicle Maintenance violations, conduct thorough pre-trip inspections on every vehicle in your fleet and repair all deficiencies immediately. The most common vehicle maintenance violations involve lights, tires, and brakes, all of which are easily identifiable and repairable. Implement a preventive maintenance schedule based on mileage and engine hours rather than calendar intervals, and document every maintenance action in a system that is accessible during roadside inspections.

For Unsafe Driving violations, review dashcam footage or telematics data to identify drivers with patterns of speeding, following too closely, or improper lane changes. Implement a driver coaching program that provides specific, data-driven feedback rather than generic safety reminders. Drivers who continue to accumulate violations despite coaching may need to be reassigned to less demanding routes or, in persistent cases, separated from the fleet.

Days 46 to 90: Build Sustainable Habits

Short-term fixes improve your score, but sustainable improvement requires building compliance into your daily operations. Establish a weekly safety review where you examine all roadside inspections from the previous week, discuss any violations with the involved drivers, and implement corrective actions. Create a driver scorecard that tracks inspection results, ELD compliance, and safety event data so that drivers see their individual performance relative to fleet averages.

Increase your clean inspection count. Every inspection that results in no violations improves your CSA percentile by demonstrating consistent compliance. Some carriers proactively seek inspections at weigh stations with Level 3 (driver-only) inspection programs because these are faster and, if the driver is compliant, add clean inspections to the record without the vehicle examination risk of a Level 1 inspection. While you cannot control when you are inspected, you can ensure that every truck and driver that leaves your yard is inspection-ready every day.

Measuring Progress

CSA scores are updated monthly, so you should see movement within 30 to 60 days of implementing corrective actions. Track your percentile in each BASIC monthly and compare it to your baseline from Day 1. If specific BASICs are not improving as expected, revisit your root cause analysis and determine whether additional corrective actions are needed. Carriers who follow this 90-day framework typically see percentile improvements of 10 to 30 points in their most elevated BASICs, which is often enough to drop below intervention thresholds and regain access to quality freight opportunities.

ArrowLane monitors carrier CSA scores as part of our network qualification process. Carriers who demonstrate improving safety trends receive priority consideration for premium freight opportunities, creating a direct financial incentive for CSA improvement beyond just avoiding FMCSA enforcement.
