An unsatisfactory safety rating is FMCSA's lowest rating. It means a carrier lacks adequate safety management controls, and that gap has already resulted in the problems listed in 49 CFR 385.5. As of October 2026, a proposed Unsatisfactory rating bars most carriers from operating on day 61 after the notice, or day 46 for placardable hazmat and passenger carriers, unless they fix the problems first.
The rating comes from a compliance review, not from CSA scores. You have two ways to respond: prove FMCSA made an error (49 CFR 385.15), or prove you have corrected the problems (49 CFR 385.17). Both work best when filed in the first 15 days.
What an unsatisfactory safety rating means
The Federal Motor Carrier Safety Administration (FMCSA) assigns one of three ratings after a compliance review, or leaves a carrier "unrated." As of October 2026 (final, in effect), 49 CFR 385.3 defines Unsatisfactory as a carrier that "does not have adequate safety management controls in place to ensure compliance with the safety fitness standard which has resulted in occurrences listed in § 385.5."
Compare that with Conditional, where the same gap "could result" in those occurrences. The occurrences in 385.5 include commercial driver's license (CDL) violations, missing insurance, unqualified drivers, improper driving, unsafe vehicles, fatigued drivers, poor maintenance, hazmat violations and crashes.
A proposed Unsatisfactory rating is "a notice to the motor carrier that the FMCSA has made a preliminary determination that the motor carrier is 'unfit' to continue operating in interstate commerce" (385.11(d)). People also call this a "DOT unsatisfactory rating." The label is the same; FMCSA is the Department of Transportation (DOT) agency that issues it.
How a carrier ends up rated Unsatisfactory
FMCSA uses the factors in 385.7 through the methodology in Appendix B to Part 385. As of October 2026, it works like this:
- Points per factor. Each acute violation, or each pattern of critical violations, is one point. A pattern means more than one violation, and at least 10% of the records examined. A pattern of hours-of-service critical violations is two points.
- Factor ratings. Zero points is Satisfactory, one is Conditional, two or more is Unsatisfactory. There are six factors: General, Driver, Operational, Vehicle, Hazardous Materials and Accident.
- The Accident factor. It applies only with two or more recordable accidents in the 12 months before the review. It is Unsatisfactory above 1.5 recordable accidents per million miles, or 1.7 for carriers operating entirely within 100 air miles.
- The rating table. The overall rating is Unsatisfactory if two or more factors are Unsatisfactory, or if one factor is Unsatisfactory and more than two are Conditional.
Worked example: one fleet, two findings
Illustration only. An invented fleet, to show the arithmetic.
| Finding in the review | Factor | Points | Factor rating |
|---|---|---|---|
| Pattern of false records of duty status | Operational | 2 (hours-of-service pattern) | Unsatisfactory |
| 3 recordable accidents in 12 months, 1.8 per million miles | Accident | Rate above 1.5 | Unsatisfactory |
| No acute or critical findings | General, Driver, Vehicle, Hazmat | 0 | Satisfactory |
| Overall | 2 Unsatisfactory factors | Unsatisfactory |
Two findings were enough. The log pattern alone made one factor Unsatisfactory, because hours-of-service patterns count double. That makes the logs a sensible first place to look. Our hours of service rules guide covers the limits a log audit checks.

The unsatisfactory rating timeline, day by day
The clock runs from the date on FMCSA's notice, which must come no later than 30 days after the review (385.11(a)). This worked timeline is for a general property carrier, as of October 2026. Hazmat and passenger carriers follow the shorter column.
| Day after the notice | General property carrier | Placardable hazmat or passenger carrier | Rule |
|---|---|---|---|
| 0 | Notice of proposed Unsatisfactory, with the list of deficiencies to correct | Same | 385.11(a) |
| By 15 | File an administrative review now if you want a decision before the prohibition | Same | 385.15(c)(1) |
| 15 + 45 = 60 | Latest FMCSA decision on a review or upgrade request filed on day 15 (45-day review) | 15 + 30 = 45 (30-day review) | 385.15(e), 385.17(e) |
| 45 | Proposed rating becomes final | 385.11(c)(1) | |
| 46 | Prohibited from operating; an upgrade request does not stop this clock | 385.13(a)(1), 385.17(f) | |
| 60 | Proposed rating becomes final | 385.11(c)(2) | |
| 61 | Prohibited from operating, unless FMCSA grants extra time | 385.13(a)(2) | |
| 61 to 120 | Up to 60 more days if FMCSA finds a good-faith effort to improve | No extension available | 385.13(a)(2), 385.17(g) |
| 90 | Last day to request administrative review of the proposed rating | Same | 385.15(c)(2) |
Read the table as a warning about timing. If you file on day 15, FMCSA's 45-day deadline lands on day 60, the day before the prohibition. File later and the decision may come after you're already off the road.
What happens if it becomes final
A final Unsatisfactory rating has three consequences under 385.13, as of October 2026:
- Out-of-service order. FMCSA "will issue an order placing out of service the motor carrier's operations in commerce," covering interstate operations and operations affecting interstate commerce. This is what people mean by an "out of service order" from a safety rating. It is different from a roadside out-of-service order on one driver or vehicle.
- Revocation of operating authority. FMCSA will, after notice, revoke the carrier's operating authority registration.
- No federal business. Federal agencies must not use a carrier rated Unsatisfactory.
A carrier that operates in violation of the order is subject to the penalties in 49 U.S.C. 521(b). A State's intrastate out-of-service order can also trigger a federal interstate one, under conditions in 385.13(d)(2).
FMCSA's public SMS site states the dividing line plainly: unless a carrier "has received an UNSATISFACTORY safety rating under part 385" or has otherwise been ordered to stop, "it is authorized to operate on the Nation's roadways" (FMCSA SMS). Ratings are public on SAFER at safer.fmcsa.dot.gov or by phone at (800) 832-5660 (385.19).
Your two options: administrative review vs upgrade request
The two routes answer different questions. Plain version: 385.15 says "you got it wrong," and 385.17 says "we fixed it, re-rate us."
| Administrative review (385.15) | Rating change for corrective action (385.17) | |
|---|---|---|
| Use it when | You believe FMCSA made a factual or procedural error | You have corrected the deficiencies |
| Send to | Assistant Administrator, ATTN: Adjudications Counsel, FMCSA, Washington, DC | The FMCSA Service Center for your principal place of business (addresses in 49 CFR 390.27) |
| Must include | The error, "a list of all factual and procedural issues in dispute," supporting documents | "a written description of corrective actions taken," plus documentation that you now meet 385.5 and 385.7 |
| Deadline | Within 15 days to assure a decision in time; no later than 90 days | "At any time" |
| FMCSA must decide within | 45 days (30 for hazmat and passenger) | 45 days (30 for hazmat and passenger) |
| If it fails | The decision is final agency action | You may request administrative review within 90 days of the denial |
Sources: 385.15 and 385.17, as of October 2026. You can use both. Any carrier "may request a rating change under the provisions of § 385.17" while it disputes the rating (385.15(g)).
How to upgrade an unsatisfactory safety rating
An upgrade comes from evidence, not from waiting. Part 385 sets no expiration date for a rating. These steps follow the text of 385.17:
- Start from the deficiency list. The notice under 385.11(a) lists the regulations you must correct. That list is your scope.
- Fix the control, not only the record. A pattern of false logs points to a missing log-audit process or a dispatch practice that pushes drivers past their hours. Correct the process and keep proof: new policies, training records, audit results.
- Write the request. 385.17(c) requires evidence "that it has taken corrective actions and that its operations currently meet the safety standard and factors specified in §§ 385.5 and 385.7."
- Send it to the Service Center early. For a general carrier, filing within the first 15 days leaves room for FMCSA's 45-day review before day 61.
- Ask about the good-faith extension. If FMCSA finds you are making a good-faith effort to improve, it may allow up to 60 more days for carriers other than hazmat and passenger carriers (385.17(g)).
- Read the answer. FMCSA notifies you in writing of an upgrade (385.17(h)) or a denial (385.17(i)). A rating that improves a previous Unsatisfactory becomes final on the notice date (385.11(b)).
Our safety management plan for a conditional rating organizes the same kind of corrective-action request, deficiency by deficiency. If your upgrade is to Conditional, our conditional safety rating guide covers what that rating allows and how to keep improving.
New entrants: a failed audit is not a rating
A new carrier that fails its new entrant safety audit does not receive an Unsatisfactory rating. Safety audits "do not result in safety ratings" (385.3). The failed audit has its own clock and can end in revocation of the new entrant registration. A new entrant found "unfit" after a compliance review has its new entrant registration revoked (385.333(b)). See our comparison of the new entrant safety audit vs compliance review.
How common is an unsatisfactory rating?
Rare, among reviewed carriers. In fiscal year 2019, FMCSA and its State partners conducted 11,671 compliance reviews. Of those, 306, under 3%, resulted in a final Unsatisfactory rating, 1,842 in Conditional and 2,701 in Satisfactory (88 FR 59489). FMCSA described FY2019 as the last year before the pandemic limited reviews.
Does a high CSA score mean an unsatisfactory rating?
No. FMCSA has said its Safety Measurement System "currently is not used in any way to generate" safety fitness determinations (88 FR 59489). High BASIC percentiles can lead to an investigation, and the investigation can lead to a rating. Our guide to CSA BASICs explained covers the thresholds.
Is the rating system changing?
Not yet. FMCSA opened a Safety Fitness Determination rulemaking with an advance notice of proposed rulemaking on Aug. 29, 2023 (88 FR 59489), followed by a notice of data availability on Jan. 12, 2024 (89 FR 2195). As of October 2026 we found no proposed or final rule in the Federal Register. The three-tier ratings and the timeline above still apply.
