What is the difference between conditional and unsatisfactory?

One word in the regulation, and it is the word that matters. Conditional means the carrier does not have adequate safety management controls that could result in the occurrences listed in 49 CFR 385.5. Unsatisfactory means inadequate controls which have resulted in them. Conditional describes exposure; unsatisfactory describes damage already done.

Is a conditional rating legal to operate under?

Yes. Only an unsatisfactory rating carries the operating prohibition. A conditional carrier may run, and many do for years. The practical cost is commercial rather than regulatory, because brokers and shippers set their own floor and a good number of them will not set up a conditional carrier.

Why does my carrier have no safety rating at all?

Because nobody has done a compliance review. A safety rating comes from a compliance review, not from a new entrant safety audit. Safety audits do not result in safety ratings. Unrated is the normal condition for a new carrier and is not a mark against you, though a broker whose checklist demands "satisfactory" may still stop on it.

Can I request an upgrade before the rating becomes final?

Yes. At any time after taking corrective action. The regulation allows a request at any time from a carrier with a proposed or final conditional or unsatisfactory rating. Filing does not pause the 45 day clock for passenger and placardable hazmat carriers.

Safety record

DOT safety ratings: conditional, unsatisfactory and unrated

Q: How long do I have before an unsatisfactory rating shuts me down?

Day 46 for placardable hm or passenger-carrying cmv. Day 61 for all other carriers. FMCSA may allow a carrier other than a passenger or placardable hazmat operation up to 60 further days if it judges the carrier to be making a good faith effort to improve.

A safety rating comes out of a compliance review, and only a compliance review. It is a separate thing from a CSA percentile, and separate again from the audit a new entrant goes through. This page sets out what each rating means in the regulation, the deadlines that run once one is proposed, and the two ways to change it.

The four ratings

Rating	What the regulation says
Satisfactory	The carrier has in place and functioning adequate safety management controls to meet the safety fitness standard. Controls are adequate if they are appropriate for the size and type of operation.
Conditional	The carrier does not have adequate safety management controls in place to ensure compliance with the safety fitness standard that could result in the occurrences listed in 49 CFR 385.5(a) through (k).
Unsatisfactory	The carrier does not have adequate safety management controls in place to ensure compliance with the safety fitness standard which has resulted in the occurrences listed in 49 CFR 385.5(a) through (k).
Unrated	A safety rating has not been assigned to the carrier by FMCSA. A carrier that has never had a compliance review is unrated, which is the normal state for a new carrier.

Conditional and unsatisfactory share a sentence and differ by one clause. Conditional covers controls whose failure could produce the problems listed in the safety fitness standard. Unsatisfactory covers controls whose failure has produced them.

What FMCSA is measuring

The carrier must demonstrate it has adequate safety management controls in place, functioning effectively to ensure acceptable compliance with applicable safety requirements. The standard names eleven areas of risk those controls have to cover.

(a) Commercial driver's license standard violations (49 CFR part 383)
(b) Inadequate levels of financial responsibility (49 CFR part 387)
(c) The use of unqualified drivers (49 CFR part 391)
(d) Improper use and driving of motor vehicles (49 CFR part 392)
(e) Unsafe vehicles operating on the highways (49 CFR part 393)
(f) Failure to maintain accident registers and copies of accident reports (49 CFR part 390)
(g) The use of fatigued drivers (49 CFR part 395)
(h) Inadequate inspection, repair, and maintenance of vehicles (49 CFR part 396)
(i) Transportation of hazardous materials, driving and parking rule violations (49 CFR part 397)
(j) Violation of hazardous materials regulations (49 CFR parts 170-177)
(k) Motor vehicle accidents and hazardous materials incidents

The factors FMCSA may consider when assigning a safety rating after a compliance review. Out of service violations appear on that list in their own right, which is one of the places a poor roadside record feeds a rating rather than only a percentile.

The clock, once a rating is proposed

FMCSA issues a rating within 30 days of finishing a compliance review. A satisfactory rating, or one that improves a previous unsatisfactory, is final on the date of the notice. Everything else arrives as a proposed rating with a deadline attached.

Carrier type	Proposed rating becomes final	Unsatisfactory carrier must stop
Placardable HM or passenger-carrying CMV	Day 45	Day 46
All other carriers	Day 60	Day 61

A carrier rated unsatisfactory is prohibited from operating a commercial motor vehicle from the day shown. FMCSA may extend that by up to 60 days for a carrier other than a passenger or placardable hazmat operation that it judges to be making a good faith effort.

Requesting an upgrade after corrective action

49 CFR 385.17 is the route when you accept the findings and have fixed them. At any time after taking corrective action.

Fix the deficiencies the review named. The notice lists the compliance deficiencies you must correct. Work that list rather than a general clean-up, because the request is judged against those items and the safety fitness standard behind them.
Document what you changed, not what you intend to change. Your request must include a written description of the corrective actions taken, plus anything else you want FMCSA to weigh. A written description of the corrective actions taken, plus any other documentation the carrier wants FMCSA to consider. Evidence that a control now runs is the part that carries the request.
Send it to the right Service Center. In writing to the FMCSA Service Center for the geographic area of the carrier's principal place of business. The addresses and geographic boundaries are listed in 49 CFR 390.27.
Expect a decision inside the review window. FMCSA reviews requests from carriers with a proposed or final unsatisfactory rating within 30 days for passenger or placardable hm, and 45 days for all other carriers. If the agency finds the corrective actions were taken and your operation now meets the standard, it notifies you in writing of the upgraded rating.
If the request is denied, administrative review is the next step. A carrier whose request is denied may ask for administrative review under 49 CFR 385.15. That is also the right route from the start when your argument is that FMCSA made an error rather than that you have since fixed something.

Appealing a rating you believe is wrong

The carrier believes FMCSA made an error in assigning the rating. That is administrative review under 49 CFR 385.15, and it is a different argument from the upgrade request: you are saying the rating was mistaken when it was issued, not that you have since corrected something.

A request must be made within 90 days of the date of the proposed rating. Where a proposed unsatisfactory rating is involved, FMCSA advises filing within 15 days of the notice, which is what gives the agency room to decide before the operating prohibition takes effect.

What a broker does with your rating

Vetting platforms read the rating straight off the FMCSA record, and many broker setup rules accept satisfactory or none while rejecting conditional outright. Brokers that work with new authority lists the minimums six brokers publish on their own carrier pages, and the MC number lookup shows the rating currently on your record alongside the rest of what a platform reads.

A rating is not a percentile. If the number you are worried about is a BASIC percentile rather than a letter rating, CSA scores is the page for it, and DataQs is how a wrong violation behind it gets corrected.
