There Is No "DOT Audit" in Part 385. There Are Two Reviews, Scored Differently
ON THIS PAGE7 sections
49 CFR 385.3 defines two examinations of a motor carrier, and neither is called a DOT audit. A safety audit is “an examination of a motor carrier’s operations to provide educational and technical assistance…” and 385.317 says flatly that it “will not result in a safety fitness determination.” A compliance review is “an examination of motor carrier operations… to determine whether a motor carrier meets the safety fitness standard in this part,” and under 385.9 it ends in a rating.
Which one is coming decides what gets sampled, how the points are counted, and whether the worst outcome is a corrective action plan or an out-of-service order. They run on different arithmetic, in two different appendices.
What are the review types, and who gets each?
Two defined examinations, plus the two forms a compliance review can take.
| Review | Who is subject | Authority | Assigns a rating? | Scored under |
|---|---|---|---|---|
| New entrant safety audit | Carriers in the 18-month new entrant monitoring period | 385.307, 385.311 | No — 385.317 | Appendix A to part 385 |
| Comprehensive compliance review | Any carrier; all regulatory factors in full | 385.3, 385.9 | Satisfactory, Conditional or Unsatisfactory | Appendix B to part 385 |
| Focused compliance review | Any carrier; fewer than all factors | 385.3, 385.9 | Conditional or Unsatisfactory, or no rating | Appendix B to part 385 |
The comprehensive/focused split is not in the regulation text — it is how FMCSA describes its own practice. In its August 29, 2023 advance notice of proposed rulemaking on safety fitness determinations (docket FMCSA-2022-0003), the agency wrote: “A comprehensive CR may result in a satisfactory, conditional, or unsatisfactory safety rating. A focused CR may result in a conditional or unsatisfactory safety rating or may not result in a safety rating.” The same document confirms a review need not be a visit: it “may be conducted on-site at the motor carrier’s place of business and/or remotely through a review of its records using a secure portal” (88 FR 59489).
What triggers each one?
The safety audit is automatic; the compliance review is targeted. Every new entrant is “subject to the new entrant safety monitoring procedures for a period of 18 months” under 385.307, and the audit comes once the carrier “has been in operation for enough time to have sufficient records… This period will generally be at least 3 months.” The outer deadline is in the 385.3 definition of new entrant registration: within 12 months of receiving the USDOT number for property carriers, 120 days for passenger carriers.
A new entrant can pull that forward. 385.308(a) lists seven actions — among them using a driver without a valid CDL, operating a vehicle placed out of service without corrective action, using a driver who tested positive or refused a test, operating without the financial responsibility required by part 387, and a driver or vehicle out-of-service rate of 50 percent or more based on at least three inspections in a consecutive 90-day period. A carrier found in any of them “may be subjected to an expedited safety audit or a compliance review or may be required to submit a written response demonstrating corrective action.”
For everyone else, 385.3 names the reasons: “in response to a request to change a safety rating, to investigate potential violations of safety regulations by motor carriers, or to investigate complaints or other evidence of safety violations.” Prioritization runs off the Safety Measurement System, FMCSA’s system “to identify motor carriers for investigation that demonstrate through safety data that they pose safety risk” — how those percentiles are built is covered in our guide to CSA scores. The same 2023 notice reports that in fiscal year 2019 “FMCSA and its State partners conducted 11,671 CRs out of a population of more than 567,000 active interstate motor carriers,” of which 306 ended in a final Unsatisfactory rating, 1,842 in Conditional and 2,701 in Satisfactory (88 FR 59489).
What does the investigator actually open?
Driver files, duty status records and maintenance records, in both reviews. 385.311 lists the safety audit areas: driver qualification, driver duty status, vehicle maintenance, accident register, and controlled substances and alcohol use and testing — a “review of the new entrant’s safety management systems and a sample of required records.” Appendix B describes the compliance review the same way: “Documents such as those contained in driver qualification files, records of duty status, vehicle maintenance records, and other records are thoroughly examined for compliance with the FMCSRs and HMRs.”
Two production rules matter more than they look. 385.307(c) requires that “all records and documents required for the safety audit shall be made available for inspection upon request” by a certified auditor. And 390.29(b) gives you 48 hours to produce records kept at a regional office or driver work-reporting location, “Saturdays, Sundays, and Federal holidays are excluded.” A qualification file living in a vendor portal nobody at your terminal can export is a file you do not have — see the DQ file guide and the printable checklist.
How is each one scored?
Same list of acute and critical regulations, two different formulas. Both appendices draw on the same list: appendix A states that “the list of the acute and critical regulations… is included in Appendix B, VII. List of Acute and Critical Regulations.” Acute regulations are those “where noncompliance is so severe as to require immediate corrective actions.” Critical regulations are those “where noncompliance relates to management and/or operational controls.”
| Safety audit — appendix A | Compliance review — appendix B | |
|---|---|---|
| Acute violation | 1.5 points per instance | 1 point per instance |
| Critical violation | 1 point per instance | 1 point per pattern |
| What is a pattern | Not used | More than one violation; where documents are sampled, at least 10% of those examined |
| Part 395 critical | No special weighting | 2 points per pattern |
| Factor threshold | 3 or more points = no basic safety management controls for that factor | 0 points Satisfactory, 1 point Conditional, 2 or more Unsatisfactory |
| Overall failure | Inadequate in at least 3 separate factors | 2+ Unsatisfactory factors, or 1 Unsatisfactory plus more than 2 Conditional |
| Vehicle out-of-service rate | 34% or higher over 3+ inspections in 12 months adds 1 point | 34% or greater over 3+ inspections makes the initial factor rating Conditional |
| Accident factor | Only with 2+ recordable accidents in 12 months; above 1.7 per million miles for a carrier operating entirely within a 100 air-mile radius, above 1.5 for all others | Same thresholds, same 2-accident trigger |
Read the critical row twice. On a safety audit, each instance is a point: three missing annual MVRs is three points and a failed Driver factor. On a compliance review, three missing MVRs out of sixty files sampled is not a pattern at all, because a pattern needs at least 10 percent of the documents examined.
The factor groupings are stable across both: Factor 1 General (parts 387 and 390), Factor 2 Driver (parts 382, 383 and 391), Factor 3 Operational (parts 392 and 395), Factor 4 Vehicle (parts 393 and 396), Factor 5 Hazardous Materials (parts 397, 171, 177 and 180), Factor 6 Accident.
The new entrant audit carries one mechanism the compliance review does not: 385.321(b) lists 16 regulations that fail the audit outright, independent of any point total. Fourteen are single occurrence; only 395.8(a) and 396.17(a) require a 51 percent violation rate. The new entrant audit walkthrough goes through all sixteen.
What are the outcomes and the deadlines?
Different consequences, both on short clocks.
| Event | Safety audit | Compliance review |
|---|---|---|
| Notice of result | Not later than 45 days after completion — 385.319(b), (c) | Rating within 30 days of completion — 385.9(b); written notice not later than 30 days — 385.11(a) |
| If you fail | Notice that new entrant registration will be revoked absent corrective action | Proposed Conditional or Unsatisfactory rating with a list of deficiencies |
| Time to act | 60 days; 45 days for passenger and placarded HM carriers — 385.319(c) | Proposed rating becomes final after 45 days (passenger/HM) or 60 days — 385.11(c) |
| Extension | Up to 60 additional days, or 10 for the 45-day group — 385.323 | Up to 60 additional days on a good-faith showing — 385.13(a)(2) |
| If you do not correct | Out-of-service order on day 61, or day 46 — 385.325(b) | Prohibited from operating a CMV on the 46th or 61st day — 385.13(a) |
| Appeal | Administrative review; file within 15 days for a decision first, 90-day outer limit — 385.327 | Administrative review under 385.15, same 15-day and 90-day structure |
| Route back | Reapply no sooner than 30 days after revocation — 385.329 | Rating change based on corrective actions, any time — 385.17 |
Two consequences carriers underestimate. A final Unsatisfactory triggers revocation of operating authority under 385.13(e), not merely an out-of-service order. And refusing the safety audit reaches the same place on its own: 385.337 gives you 10 days to agree in writing, and revocation takes effect on the 11th. Do not reconstruct records in the meantime — 390.35 is on the acute list in appendix B for “making, or causing to make fraudulent or intentionally false statements or records,” which is 1.5 points on a safety audit and 1 on a compliance review, on top of whatever was missing.
What a clean audit does not tell you
It tells you your paperwork system works. It says nothing about the people in the trucks. Every factor above is a compliance measure. Factor 2 asks whether a qualification file exists, whether the MVR was pulled, whether the medical certificate is current — not whether the driver in that file was worth hiring. The cost of a bad hire never appears in any of the six factors.
The required pre-employment record has the same blind spot. The safety performance history request under 391.23 asks previous employers for “general driver identification and employment verification information,” accident data and drug and alcohol history. Nothing on that list asks whether the driver answered dispatch, returned the equipment, or finished the contract.
That is the layer cdlscan exists for: reviews written by carriers who actually employed the driver, covering conduct the federal record has no field for — see how carrier-written driver reviews work.
The boundary matters most with an investigator in the room: this sits on top of the required records, never in place of any part of them. The qualification file under 391.51, the inquiries under 391.23 and 391.25, the Clearinghouse queries under 382.701 and every record the auditor samples are legally required, and nothing here discharges any of them. Nothing in part 385 or part 391 permits peer-sourced review data to substitute for a required record. If you intend to rely on third-party information about a driver as a factor in an employment decision, ask the provider which category of information they consider it under the Fair Credit Reporting Act, and confirm which obligations attach with your own counsel — the FTC’s guidance on using consumer reports is where to start.
Frequently asked questions
Is a DOT audit the same thing as a compliance review?
Not necessarily. Part 385 defines the two as separate examinations. Inside the 18-month new entrant monitoring period under 385.307, what you face is a safety audit, which cannot assign a safety rating. Once registration is permanent, it is a compliance review, and 385.9 says it produces one.
Can a DOT audit shut down my operation?
Both routes lead there. A failed safety audit ends in revocation of new entrant registration and an out-of-service order on day 61 or day 46 under 385.325(b). A final Unsatisfactory prohibits CMV operation from the 46th or 61st day under 385.13(a), and revokes operating authority under 385.13(e).
How much notice do I get before an audit?
Part 385 sets no advance-notice period for either review. What it does set is the 48-hour production deadline in 390.29(b). Build to that number, not to a hoped-for warning.
Can I get a Satisfactory rating out of a focused review?
No. FMCSA states that a focused CR “may result in a conditional or unsatisfactory safety rating or may not result in a safety rating.” Only a comprehensive review covering all regulatory factors in full can produce a Satisfactory. To upgrade a Conditional, request a rating change based on corrective actions under 385.17.
