How to Monitor and Improve CSA Scores for Your Fleet

A problem with your CSA performance usually begins before the Safety Measurement System displays an alert. It may start with a recurring maintenance issue, an unchecked log, an unrealistic delivery schedule, or an expired document that went unnoticed.

The Safety Measurement System, or SMS, makes the consequences of those problems visible. However, the SMS result only shows the outcome. Improving your performance requires accurate data, stronger safety procedures, and consistent action to prevent the same violations from happening again.

This is especially important for owner-operators and small fleets. When a carrier has relatively few inspections, a small number of violations can have a significant effect on its performance within a BASIC category.

If you first need to understand how CSA percentiles and BASIC categories work, read our guide to CSA scores and how they affect your trucking business.

FMCSA may update its methodology and review procedures. Use the official resources linked throughout this guide to confirm the requirements in effect when reviewing your data or submitting a request.

How Often Should You Review Your SMS Data?

You should review your SMS data at least once a month. FMCSA updates the system monthly after processing the latest inspection, violation, crash, and investigation information.

Carriers can log in to the FMCSA Safety Measurement System to review their complete results. Compare each update with the previous month and look for:

• New inspections, violations, or crashes.
• Violations that were added, changed, or removed.
• Driver or vehicle out-of-service orders.
• Changes in BASIC measures or percentiles.
• Errors involving drivers, vehicles, or company information.
• Corrective actions that are still pending.

FMCSA explains that SMS takes a new data snapshot every month and then processes, validates, and publishes the results.

You should also record when each event moves into a different time-weighting period:

This timeline helps explain why a BASIC measure or percentile may change even when you have not received a new violation. Percentiles also compare your performance with other carriers, so changes within your comparison group can affect your result.

FMCSA provides the complete formulas, data requirements, and weighting rules in its official SMS Methodology.

How Can You Identify What Is Causing the Problem?

To identify the cause of a CSA problem, analyze violations by type, frequency, severity, driver, vehicle, and date. The objective is to find patterns instead of treating every violation as an isolated event.

For example, several lighting violations may show that your pre-trip inspections are not working effectively. Multiple hours-of-service violations involving different drivers could indicate a dispatch-planning issue rather than isolated driver behavior.

When reviewing your inspection history, consider:

• The violation code and type.
• The driver involved.
• The truck or trailer.
• The date, lane, or operating location.
• Whether an out-of-service order was issued.
• How often the problem has occurred.
• Who is responsible for the related process.

FMCSA’s Safety Management Cycle can help carriers look beyond the violation itself. It recommends reviewing six areas of the operation: policies and procedures, roles and responsibilities, qualification and hiring, training and communication, monitoring and tracking, and meaningful action.

Instead of asking only, “How do we lower the percentile?” ask, “Which part of our operation continues to produce these violations?”

How Can You Correct Inaccurate Information Through DataQs?

You can use DataQs to request a review when an inspection, violation, or crash record contains inaccurate or incomplete information.

Before submitting a Request for Data Review, identify the error and gather documents that support your position. Depending on the case, your evidence may include:

• The inspection report.
• Photographs or videos from the event.
• Driver or vehicle documents.
• ELD or dispatch records.
• A court disposition.
• The police accident report.
• Other records that demonstrate the information is inaccurate.

Your request should explain which information is incorrect, why it should be changed, and how the supporting evidence proves the error.

A repair order issued after an inspection can show that you corrected the problem. However, it does not automatically prove that the original violation was recorded incorrectly. Include repair records only when they establish a fact relevant to the disputed information.

DataQs does not remove a valid violation simply because it is affecting your CSA performance. Its purpose is to correct inaccurate, incomplete, duplicate, or improperly assigned information.

If your request is denied, review the explanation, determine whether additional evidence is available, and request reconsideration when you have valid grounds to challenge the decision. Consult the DataQs Help Center for current procedures and documentation requirements.

When Can You Request a Crash Preventability Review?

You may request a crash preventability review when the crash falls within an eligible crash type and meets FMCSA’s documentation requirements.

Eligible cases include certain crashes in which the commercial vehicle was struck from behind, was legally stopped, was hit by a driver traveling in the wrong direction, or was involved in an incident where video evidence clearly establishes what happened.

Submit the request through DataQs and include the police accident report. You can also provide photographs, dashcam recordings, witness statements, and other relevant evidence.

The FMCSA Crash Preventability Determination Program limits eligibility based on the crash type, date, and available evidence. If FMCSA determines that the crash was not preventable:

• The crash is excluded from the Crash Indicator BASIC calculation.
• It remains visible in SMS with FMCSA’s determination.
• The determination also appears in the driver’s Pre-Employment Screening Program record.

Road-facing cameras and procedures for preserving evidence after a crash can be valuable. The strength of your request will depend on the quality of the information you can provide.

What Actions Can Improve Each BASIC Category?

Your improvement plan should focus on the BASIC category generating the violations. General safety training can help, but it does not replace a response targeted at the specific cause of the problem.

Every corrective action should have a responsible person, a completion date, and a way to verify completion. A written policy provides little value if no one confirms that it is being followed.

Why Should You Document Corrective Actions?

Documenting corrective actions shows that you identified the problem, corrected the condition, and established controls to prevent it from happening again.

Keep inspection checklists, work orders, repair receipts, maintenance records, driver training records, ELD reviews, communications, policy changes, and follow-up audits.

This evidence may be useful during a DataQs request, an FMCSA communication or investigation, or an internal review following another violation.

Do not simply record that a driver completed training or that a truck was repaired. Document the problem, the action taken, the person responsible, the completion date, and how you will confirm that the solution is working.

Why Should You Keep Your MCS-150 Updated?

You should keep your MCS-150 updated because FMCSA uses information such as power units and vehicle miles traveled to measure exposure within certain BASIC categories.

Review the following information carefully:

• Number of power units.
• Number of drivers.
• Vehicle miles traveled during the previous year.
• Business address and contact information.
• Type of operation and cargo transported.

FMCSA requires a biennial registration update, even when your company’s information has not changed. You should also update your USDOT record when relevant company or operational information changes.

Reporting too many or too few power units, or using outdated mileage, can prevent SMS from accurately measuring your carrier’s activity level.

Do Clean Inspections Improve CSA Performance?

Relevant inspections without violations can improve certain inspection-based BASIC measures, but they do not erase previous violations.

These inspections can affect Hours-of-Service Compliance, Vehicle Maintenance, Controlled Substances and Alcohol, Hazardous Materials Compliance, and Driver Fitness because their calculations include relevant inspections. They do not directly improve Unsafe Driving or Crash Indicator through an inspection denominator because those categories use different exposure calculations.

An inspection is relevant only when its level covers the area the BASIC evaluates. A relevant inspection without violations may improve the measure, but it does not guarantee that the percentile will immediately decline. The result also depends on data sufficiency and the performance of comparable carriers.

The objective should not be to seek inspections simply to lower a percentile. It should be to prepare every truck and driver to pass an inspection whenever one occurs.

How Long Does It Take to Improve CSA Performance?

There is no fixed timeline for improving a CSA percentile. Results may begin to change after a successful DataQs correction, a relevant inspection without violations, or a monthly SMS update.

Sustainable improvement usually takes several months because previous events remain in the calculation, recent violations carry greater weight, and percentiles depend on the performance of comparable carriers. A new violation can also delay the progress already made.

Instead of focusing only on a target percentile, monitor indicators you can control. These include violations per inspection, out-of-service orders, repeat violations, overdue repairs, log errors, expiring documents, and corrective actions that still need verification.

These indicators show whether your safety procedures are improving before the change becomes visible in your percentile.

How Stable Cash Flow Can Support CSA Improvement

Factoring does not lower CSA scores, remove violations, or replace a safety program. It can help a trucking company maintain the cash flow needed to complete corrective actions on time.

Brake repairs, tire replacements, preventive maintenance, ELD services, and driver training all require money. These expenses cannot always wait the 30, 45, or 60 days it may take a broker to pay for a delivered load.

Freight factoring allows carriers to convert eligible invoices into working capital faster. This can reduce the pressure to postpone maintenance, repairs, or other important expenses while waiting for brokers to pay.

Access to cash does not guarantee strong CSA performance. However, it can give you more flexibility to take a truck out of service for repairs instead of continuing to operate it because cash is unavailable.

Improvement happens before the next inspection. Review your SMS data every month, correct inaccurate records, preserve your evidence, and focus your resources on the BASIC category that needs attention. An older violation will lose weight over time, but only consistent operations will keep it from being replaced by another.
