Quick checklist

  • Know whether the notice is a safety audit, compliance review, or another FMCSA intervention.
  • Check your public and private safety data in official FMCSA systems.
  • Understand the difference between CSA BASICs and a formal safety rating.
  • Treat Conditional and Unsatisfactory ratings as time-sensitive business issues.
  • Save any audit result, rating notice, or follow-up correspondence.
  • Use official review channels if you believe records or data are wrong.

Why this matters

Carriers often prepare documents for the audit but forget the next question: what does the result mean for the business? CSA data and safety ratings are different systems, and mixing them up can lead to bad decisions.

What to prepare

Area Records to gather
CSA basics
  • Unsafe Driving
  • Crash Indicator
  • Hours-of-Service Compliance
  • Vehicle Maintenance
  • Controlled Substances/Alcohol
  • Hazardous Materials Compliance where applicable
  • Driver Fitness
Safety rating terms
  • Satisfactory: the carrier has adequate safety management controls based on the review
  • Conditional: safety management controls do not fully meet the safety fitness standard; corrective evidence may be needed
  • Unsatisfactory: can lead to operating restrictions after the rating becomes final
  • Unrated: no safety rating has been assigned
Timing notes
  • Corrective-action requests and administrative review windows are time-sensitive; check the notice and 49 CFR Part 385
  • Unsatisfactory rating consequences differ by carrier type and timing; read the official notice carefully
  • New entrant safety audits are usually pass/fail safety assurance events, not the same as receiving a standard safety rating
After-review file
  • Audit or review result
  • Safety rating notice if issued
  • Corrective action records
  • Data review or support documents where applicable

Common gaps

  • Assuming a CSA percentile is the same thing as a safety rating.
  • Treating a Conditional rating as a paperwork note instead of a corrective-action issue.
  • Waiting until after a review to look at roadside inspection data.
  • No one saves the final rating notice or review correspondence.
  • Disputes are discussed internally but not backed by source records.

Before / During / After audit

Before

  • Look up safety data in official FMCSA systems.
  • Compare roadside inspection issues with your audit packet.
  • Flag repeat BASIC areas for internal review.

During

  • Keep answers tied to records and corrective actions.
  • Ask where final results or rating notices will be sent.

After

  • Read the final correspondence carefully.
  • Track corrective actions by BASIC or record category.
  • Use official review procedures when data or findings need to be challenged.
