An FMCSA safety rating is the Federal Motor Carrier Safety Administration's official determination of whether a motor carrier has adequate safety management controls in place to meet the safety fitness standard in 49 CFR Part 385. After an on-site or offsite investigation, FMCSA assigns one of three ratings: Satisfactory, Conditional or Unsatisfactory. Carriers that have never been rated are listed as Unrated.
The rating matters because shippers, brokers and insurers check it, and because an Unsatisfactory rating that becomes final prohibits a carrier from operating commercial motor vehicles in interstate commerce.
What Is an FMCSA Safety Rating?
Under 49 CFR Part 385, a safety rating reflects how well a carrier controls its operations, not simply whether it has had crashes. The ratings are defined as follows:
- Satisfactory: the carrier has functioning safety management controls that meet the safety fitness standard.
- Conditional: the carrier's controls are not adequate to ensure compliance, and that shortfall could lead to violations. The carrier may keep operating.
- Unsatisfactory: the carrier's controls are inadequate and have resulted in violations of the safety fitness standard. A final Unsatisfactory rating means the carrier must stop operating CMVs in interstate commerce.
- Unrated: no rating has been assigned. This is not a negative rating, and many carriers are Unrated.
The safety rating is separate from CSA scores in the Safety Measurement System. SMS data helps FMCSA decide which carriers to investigate, but only an investigation produces a rating.
How a Rating Is Determined
FMCSA assigns ratings after a compliance review, now usually called a comprehensive investigation, which may be done at the carrier's place of business or offsite using records the carrier submits. Investigators review a sample of records and evaluate six rating factors:
- General: insurance, registration and other general requirements.
- Driver: driver qualification, CDL and drug and alcohol testing.
- Operational: hours of service and related rules.
- Vehicle: inspection, repair and maintenance, including roadside out-of-service rates.
- Hazardous materials: where the carrier hauls hazmat.
- Accident: the carrier's recordable crash rate.
Each factor is rated based on acute and critical violations listed in Appendix B to Part 385. An acute violation is so serious that it requires immediate correction regardless of the carrier's overall controls, such as allowing a driver to operate after refusing a required drug or alcohol test. A critical violation points to a breakdown in management controls, such as failing to keep driver qualification files or not requiring drivers to keep records of duty status. Critical violations generally count against a factor when a pattern is found across the records reviewed. The factor ratings are then combined in a rating table to produce the overall rating.
Timelines After a Proposed Unsatisfactory Rating
When an investigation results in a proposed Unsatisfactory rating, FMCSA sends a notice. Under 49 CFR 385.13, the prohibition on operating begins on the 46th day after the notice for passenger carriers and carriers of placardable quantities of hazardous materials, and on the 61st day for all other carriers. FMCSA may grant other carriers up to 60 additional days if they are making a good-faith effort to improve.
A carrier can respond in two ways:
- Request a change to the rating (upgrade) under 385.17. The carrier submits evidence of corrective action. For proposed or final Unsatisfactory ratings, FMCSA reviews the request within 30 days for passenger and placardable hazmat carriers and within 45 days for others.
- Request administrative review under 385.15. This argues that FMCSA made an error in assigning the rating. The request must be made within 90 days, and FMCSA advises filing within 15 days of a proposed Unsatisfactory notice so a decision can be made before the prohibition takes effect.
Carriers with a Conditional rating can also request an upgrade at any time by documenting corrective actions.
How to Request a Safety Rating Upgrade Step by Step
- Read the investigation report. Identify every acute and critical violation and the rating factor it affected.
- Find the root cause. Ask why each violation happened, such as missing procedures, untrained staff or poor recordkeeping, using a root cause analysis.
- Put corrective actions in place. Write or update policies, assign responsibility and fix the underlying system, not just the individual record.
- Gather evidence. Collect documents showing the corrections work, such as completed driver qualification files, testing program records, maintenance records and training records.
- Write a corrective action plan. Address each violation, the cause, the fix and how it will be monitored.
- Submit the request. Send the written request and supporting documents to FMCSA as directed in the rating notice.
- Monitor and sustain. Keep auditing the same areas so the problems do not return before the next review.
Common Mistakes to Avoid
- Confusing CSA scores with the safety rating, and ignoring the rating until an investigation happens.
- Missing the deadlines after a proposed Unsatisfactory rating.
- Submitting an upgrade request that describes intentions rather than documented, completed corrective actions.
- Fixing individual files without fixing the process that let them lapse.
- Overlooking drug and alcohol testing program gaps, which are a frequent source of acute and critical violations.
How SMS360 Helps
SMS360's Fleet Reports give managers a view of driver, vehicle and compliance records across the fleet so gaps can be found before an investigation does. DOT Compliance tracks recurring requirements and deadlines, and Actions Management assigns and follows up corrective actions, creating the documented evidence an upgrade request needs.
Frequently Asked Questions
Can I operate with a Conditional rating?
Yes. A Conditional rating does not prohibit operations, but it signals weaknesses in safety management controls. Some shippers, brokers and insurers may restrict business with Conditional carriers, so many carriers request an upgrade once corrective actions are complete.
Does a good CSA score mean I have a Satisfactory rating?
No. CSA scores and safety ratings are separate. A carrier only receives a rating after an FMCSA investigation, and many carriers with good SMS data are Unrated.
How long does an Unsatisfactory carrier have to fix problems?
The operating prohibition begins on the 46th day after the proposed rating notice for passenger and placardable hazmat carriers, and on the 61st day for other carriers, with a possible extension of up to 60 days for other carriers making a good-faith effort.
Is the FMCSA safety rating process changing?
FMCSA has been considering changes to its safety fitness determination methodology for several years. Until a new rule is finalized, ratings continue to be issued under the current Part 385 process, so check FMCSA for the latest status.
