Quick Answer: The FMCSA new entrant safety audit places every new motor carrier in an 18-month monitoring period under 49 CFR Part 385, Subpart D, with the audit itself due within 12 months of receiving its USDOT number for property carriers, or 120 days for passenger carriers. The audit reviews five areas, and vehicle maintenance is one of them. Under §385.321(b), sixteen regulations cause automatic failure, and three of those sixteen are Part 396: operating a vehicle declared out of service before repairs (§396.9(c)(2)), failing to correct out-of-service defects listed on a DVIR (§396.11(a)(3)), and using a commercial motor vehicle that has not been periodically inspected (§396.17(a)). Fail and don’t submit acceptable corrective action, and FMCSA revokes your registration and places your operations out of service.
If you have just activated a USDOT number, the audit is coming and the date is not up to you. Most carriers who fail are not unsafe — they are undocumented. This guide covers what the audit actually reviews, which violations end it immediately, and what the vehicle maintenance side of your file needs to contain before an auditor asks.
When you activate a USDOT number to begin interstate operations, FMCSA places you in the New Entrant Safety Assurance Program under 49 CFR Part 385, Subpart D. FMCSA maintains its own overview of the program as well. That is an 18-month monitoring period, and somewhere inside it you get audited.
Section §385.309 states the purpose plainly: the audit exists to provide educational and technical assistance to the new entrant, and to gather safety data needed to assess the new entrant’s safety performance and the adequacy of its basic safety management controls.
That last phrase is the whole test. The audit is not asking whether your trucks are mechanically sound. It is asking whether you have systems in place and records that prove it. Under §385.315 it is generally conducted at your business premises, and under §385.313 it is performed by an individual certified under FMCSA regulations to conduct safety audits.
Worth knowing who actually shows up. Under §385.313 the audit is conducted by an individual certified under FMCSA regulations, but in practice the majority of new entrant safety audits are performed by FMCSA’s State partners rather than federal investigators, under the New Entrant Safety Audit Grant program. The standard applied is the same either way.
One useful clarification most guides get wrong: under §385.317, a safety audit does not result in a safety fitness determination. Satisfactory, conditional, and unsatisfactory ratings come from a compliance review, which is a different and more serious process. The audit determines whether your registration survives, not what your rating is.
Sooner than most new carriers expect, and the clock is not yours to set.
Property carriers: the audit must be performed within 12 months of receiving your USDOT number. Passenger carriers: within 120 days. Those deadlines were shortened by section 32102 of MAP-21 — the property window was previously 18 months, and the passenger window 12 months.
There is a floor as well as a ceiling. Under §385.307(b), the audit is conducted once the carrier has been in operation long enough to have sufficient records for FMCSA to evaluate its controls, and the section states this period will generally be at least 3 months.
So the practical window for a property carrier is roughly month three to month twelve. You will not be audited in week two, and you should not assume you have a year.
One trap before the clock even starts. Under §385.305(c), a new applicant is issued an inactive USDOT number, and may not begin operations nor mark a commercial motor vehicle with that number until after the date of FMCSA’s written notice that it has been activated. Putting the number on a door before activation is its own violation.
Section §385.308 lists triggers for an expedited safety audit or compliance review. Two of them are directly about equipment:
Others include using a driver without a valid CDL, using a driver who tested positive or refused a test, operating without required financial responsibility, and certain hazardous materials incidents.
Note what that second trigger means: your roadside performance controls your audit timing. Out-of-service determinations at roadside use the CVSA criteria rather than the annual inspection standard, and the two are not the same numbers — we separate them in legal, out-of-service, or failed inspection. For how a roadside stop differs from your scheduled annual inspection, see DOT annual inspection vs roadside inspection.
If you trigger one of these and have not yet been audited, FMCSA schedules the audit as soon as practicable. If you have already been audited, you get a notice demanding evidence of corrective action within 30 days — and failure to respond within 30 days results in revocation of your new entrant registration.
Section §385.311 defines the scope: a review of the new entrant’s safety management systems and a sample of required records, assessing compliance with the FMCSRs, applicable HMRs, and related recordkeeping requirements as specified in Appendix A to Part 385.
Five areas are named:
| Audit area | Governing rules |
|---|---|
| Driver qualification | Part 391, Part 383 |
| Driver duty status | Part 395 |
| Vehicle maintenance | Part 396 |
| Accident register | §390.15 |
| Controlled substances and alcohol testing | Part 382 |
The section says “include, but are not limited to,” so the list is a floor rather than a ceiling. But vehicle maintenance is named explicitly, and it carries more automatic-failure weight than any other category except drug and alcohol testing.
This is the part every new carrier should read before anything else.
Under §385.321(b), a new entrant automatically fails the safety audit if found in violation of any one of sixteen specific regulations. Most are single-occurrence — one instance ends the audit.
Three of the sixteen are Part 396 vehicle maintenance violations:
| # | Violation | Threshold |
|---|---|---|
| 14 | §396.9(c)(2) — Requiring or permitting operation of a commercial motor vehicle declared “out-of-service” before repairs are made | Single occurrence |
| 15 | §396.11(a)(3) — Failing to correct out-of-service defects listed by a driver in a driver vehicle inspection report before the vehicle is operated | Single occurrence |
| 16 | §396.17(a) — Using a commercial motor vehicle not periodically inspected | 51% or more of examined records |
The remaining thirteen cover drug and alcohol testing (§§382.115, 382.201, 382.211, 382.215, 382.305), CDL compliance (§§383.3(a)/383.23(a), 383.37(b), 383.51(a)), financial responsibility (§§387.7(a), 387.31(a)), driver qualification (§§391.15(a), 391.11(b)(4)), and records of duty status (§395.8(a)).
Note which two have thresholds and which fourteen do not. Only §395.8(a) and §396.17(a) require a violation rate to trigger automatic failure. Every other item on the list — including both of the other Part 396 violations — ends the audit on a single occurrence.
Item 16 deserves its own explanation, because the threshold is easier to cross than it sounds.
Using a commercial motor vehicle that has not been periodically inspected under §396.17(a) triggers automatic failure when 51% or more of examined records show the violation. The auditor samples your records; they do not check every vehicle.
Run the arithmetic on a small fleet. If the auditor samples four vehicles and three lack a current annual inspection, that is 75% — automatic failure. Sample two and one fails, that is 50%, which does not cross the threshold, but you are one record away.
And remember how §396.17(a) counts vehicles. Each unit of a combination is inspected separately — a tractor, semitrailer, full trailer, and converter dolly each need their own inspection and their own report. A three-truck carrier pulling five trailers has eight vehicles requiring annual inspections, not three.
For the requirement in full, see our guide to 49 CFR §396.17 periodic inspection requirements.
Four record sets, with four different retention clocks. New entrants routinely have some of these and not others.
| Record | Rule | Retention |
|---|---|---|
| Annual inspection report, per vehicle | §396.21(b)(1) | 14 months |
| Inspector qualification evidence | §396.19(b) | Period of service + 1 year |
| Brake inspector qualification | §396.25(e) | Employment in role + 1 year |
| Driver vehicle inspection reports | §396.11(a)(4) | 3 months |
The inspector qualification record is the one new entrants almost never have. You can produce a stack of inspection reports and still have a gap, because §396.19(b) requires the carrier to retain evidence that the person who performed those inspections was qualified. An inspection signed by someone whose qualification you cannot document is not a compliant inspection.
Also required: documentation of the current inspection on the vehicle, either the §396.21(a) report or a decal carrying the four items in §396.17(c)(2). See what goes on the truck and what stays in the file, and for the qualification record structure, our FMCSA inspector qualifications form guide.
Under §385.307(c), all records and documents required for the audit must be made available for inspection upon request by the certified auditor.
Someone qualified under 49 CFR §396.19. No federal agency issues a DOT inspector certification or license — the motor carrier qualifies its own inspectors and keeps the evidence on file. We explain that distinction in do you need to be certified to perform DOT annual inspections.
Under §396.17(d) a carrier may perform its own annual inspections, and under §396.17(e) it may use a commercial garage, fleet leasing company, or similar business as its agent, provided that business employs qualified inspectors. Either way, the carrier is responsible for the qualification evidence. If you outsource inspections, you should request and retain your shop’s inspector qualification documentation — because at the audit, the auditor asks you, not them.
One thing to check before you decide who inspects: if your vehicles are registered in a state with an FMCSA-approved mandatory inspection program, §396.23(a)(1) may require you to use that program. See do state DOT inspection requirements replace the federal annual inspection.
The §396.19(a)(3) standard has two routes: a Federal- or State-sponsored training program or a qualifying state certificate, or a combination of training and/or experience totaling at least one year. Most working mechanics already satisfy the experience component; what is usually missing is documented training in the federal standards.
See who can perform DOT annual inspections, our guide to FMCSA §396.19, and can I do my own DOT annual inspection.
The process is defined and the deadlines are short.
Notice within 45 days. Under §385.319, whether you pass or fail, FMCSA provides written notice as soon as practicable but not later than 45 days after the audit is completed. A failure notice states that your USDOT new entrant registration will be revoked and your operations placed out of service unless you take the specified corrective actions.
60 days to correct — or 45. Most new entrants have 60 days from the notice date. Under §385.319(c)(2), the window is 45 days for carriers transporting passengers in a CMV designed for 9 to 15 passengers for direct compensation, carriers transporting more than 15 passengers, and carriers transporting placarded hazardous materials.
Extensions are possible but not guaranteed. Under §385.323, FMCSA may extend the 60-day period by up to an additional 60 days if it determines you are making a good faith effort. The 45-day window can be extended by up to 10 days.
Miss it and you are out of service. Under §385.325(b), failure to submit acceptable corrective action results in revocation and an out-of-service order effective on day 61 from the notice date, or day 46 for the shorter-window carriers. You may not operate in interstate commerce on or after that date.
Administrative review has its own clock. Under §385.327, you may request review if you believe FMCSA erred. You have 90 days generally — but if you want a decision before the out-of-service order takes effect, you must submit within 15 days of the notice.
If your registration is revoked, §385.329 lets you reapply — but no sooner than 30 days after revocation, and the terms are worse than most carriers realize.
You submit an updated Form MCSA-1, submit evidence that you corrected the deficiencies, and then begin the 18-month new entrant monitoring cycle again from the date the refiled application is approved.
So a failed audit in month eight does not put you back to month eight. It puts you back to month zero, plus a month of downtime, plus another audit ahead of you. If you also lost operating authority as a for-hire carrier, you reapply for that separately under §390.201(b) and Part 365.
And refusing the audit is worse. Under §385.337, if you refuse to permit a safety audit, FMCSA gives you written notice that your registration will be revoked unless you agree in writing within 10 days. If you do not, revocation and an out-of-service order take effect on the 11th day.
The audit is the gate, not the destination. Under §385.333(a), if a safety audit has been performed within the 18-month period and you are not under an out-of-service order or a corrective action notice, FMCSA removes the new entrant designation and notifies you in writing that your registration has become permanent. From that point the agency evaluates you on the same basis as any other carrier.
If you reach month eighteen while still under an order to correct your safety management practices, §385.333(c) provides that the designation is removed once FMCSA determines the specified actions have been taken. You are not locked out permanently for a fixable finding.
One provision worth knowing if your audit never arrives: under §385.333(d), if no safety audit or compliance review has been performed by the end of the 18-month monitoring period through no fault of the motor carrier, you are permitted to continue operating as a new entrant until one is performed and a determination is made. The clock running out is not itself a violation.
And under §385.335, if FMCSA conducts a full compliance review on a new entrant that has not yet had a safety audit, and issues a safety fitness determination, you do not have to undergo the audit separately. You remain in the 18-month monitoring period regardless.
One hard line applies throughout. Under §385.331, a new entrant that operates a commercial motor vehicle in violation of an out-of-service order is subject to the penalty provisions of 49 U.S.C. 521(b)(2)(A) for each offense, as adjusted for inflation under 49 CFR Part 386, Appendix B. That is separate from, and on top of, the revocation itself.
Look at the sixteen automatic failures as a group. Most describe things a carrier did — used a disqualified driver, ran without insurance, put someone behind the wheel who failed a test. Those require an act.
The Part 396 items are different. They describe things a carrier failed to document. Nobody decides to skip an annual inspection as a business strategy. It happens because a new carrier bought trucks, put them to work, and never set up the inspection program — or set one up and never documented who was qualified to run it.
That is the most fixable category on the list, and it is fixable before the audit rather than after. The defects that generate roadside out-of-service orders are the same ones a proper annual inspection catches: in CVSA’s 2026 International Roadcheck, inspectors placed 10,350 of 54,575 vehicles out of service — 19% — with brake system violations alone accounting for 24.3% of all vehicle out-of-service violations. See why trucks fail DOT inspections and our 2026 CVSA International Roadcheck guide. For the broader enforcement picture a new carrier is entering, see DOT compliance enforcement in 2026.
Remember too that a 50% vehicle out-of-service rate across three inspections in 90 days triggers an expedited audit under §385.308(a)(7). Roadside performance and audit timing are connected.
Three of the sixteen automatic failures are vehicle maintenance. Two need only one occurrence.
The auditor will ask who performed your annual inspections and what proves they were qualified. Under §396.19(b), that record is the carrier’s responsibility — and it is the one new entrants almost never have.

A mandatory review under 49 CFR Part 385, Subpart D that every new motor carrier undergoes after activating a USDOT number. Under §385.309 its purpose is to provide educational and technical assistance and to assess the adequacy of the carrier’s basic safety management controls. It is a review of safety management systems and a sample of required records, not a road test.
Within 12 months of receiving a USDOT number for property carriers, and 120 days for passenger carriers. Under §385.307(b) it is conducted once the carrier has enough operating history for FMCSA to evaluate its controls, generally at least 3 months. The overall new entrant monitoring period lasts 18 months.
Section §385.311 names five areas: driver qualification, driver duty status, vehicle maintenance, accident register, and controlled substances and alcohol use and testing. The list is stated as including but not limited to those areas, and compliance is assessed against the recordkeeping requirements in Appendix A to Part 385.
Under §385.321(b), violation of any one of sixteen listed regulations. Fourteen require only a single occurrence. Three of the sixteen are Part 396 vehicle maintenance rules: §396.9(c)(2), operating a vehicle declared out of service before repairs; §396.11(a)(3), failing to correct out-of-service defects listed on a DVIR; and §396.17(a), using a commercial motor vehicle not periodically inspected. The first two are single occurrence; §396.17(a) requires 51% or more of examined records.
Yes. Item 16 of the automatic failure table is §396.17(a), using a commercial motor vehicle not periodically inspected, and it triggers automatic failure when 51% or more of examined records show the violation. Since each unit of a combination vehicle counts separately under §396.17(a), a small fleet with several trailers can cross that threshold quickly.
Yes. Under 49 CFR §396.19(b) the motor carrier must retain evidence of each annual inspector’s qualifications for the period they perform inspections plus one year. An inspection performed by someone whose qualification the carrier cannot document is not compliant, even if the inspection itself was thorough. This is the record new entrants most often lack.
Under §385.319(c) FMCSA sends written notice within 45 days of the audit stating that your registration will be revoked unless you take the specified corrective actions. Most carriers have 60 days; passenger carriers and placarded hazmat carriers have 45. Under §385.325(b), failure to submit acceptable corrective action results in revocation and an out-of-service order effective day 61, or day 46 for the shorter-window carriers.
Section §385.323 allows FMCSA to extend the 60-day corrective action period by up to an additional 60 days, provided it determines the new entrant is making a good faith effort to remedy its safety management practices. The 45-day period may be extended by up to 10 days. Extensions are discretionary, not automatic.
Yes, no sooner than 30 days after revocation under §385.329. You submit an updated Form MCSA-1 and evidence that the deficiencies are corrected, and then begin the 18-month new entrant monitoring cycle again from the date the refiled application is approved. A for-hire carrier that also lost operating authority must reapply for that separately.
Yes. Section §385.308 lists triggers for an expedited audit, including operating a vehicle placed out of service without corrective action and having a driver or vehicle out-of-service rate of 50 percent or more based on at least three inspections within a consecutive 90-day period. If you have already been audited, you instead receive a notice demanding evidence of corrective action within 30 days, and failure to respond results in revocation.
No. Under §385.317, a safety audit does not result in a safety fitness determination. Satisfactory, conditional, and unsatisfactory ratings come from a compliance review, which is a separate process. Passing the audit means FMCSA found your basic safety management controls adequate and your registration continues.
Under §385.333(a), if the audit was performed within the 18-month monitoring period and you are not under an out-of-service order or corrective action notice, FMCSA removes the new entrant designation and notifies you in writing that your registration has become permanent. After that the agency evaluates you on the same basis as any other carrier.
Under §385.333(d), if no safety audit or compliance review has been performed by the end of the monitoring period through no fault of the motor carrier, you are permitted to continue operating as a new entrant until one is performed and a determination is made. Separately, under §385.335, if FMCSA conducts a compliance review and issues a safety fitness determination before any audit, you do not have to undergo the safety audit separately.
Section §396.17(e) permits a commercial garage, fleet leasing company, or similar business to perform the inspection as your agent, provided it employs inspectors qualified under §396.19. The carrier remains responsible for the qualification evidence, so you should request and retain documentation of the shop inspector’s qualifications. At the audit, FMCSA asks you for it.
The new entrant safety audit is a records test with your operating authority attached to the result. It arrives inside your first 12 months, you do not choose the date, and sixteen specific violations end it immediately — three of which are vehicle maintenance.
Two of those three need only a single occurrence. The third, using a vehicle that has not been periodically inspected, needs 51% of the records the auditor happens to sample.
None of that is difficult to prevent. Count your vehicles, get a current annual inspection on each one performed by a qualified inspector, document the qualification, and keep the file where you can produce it. A new carrier who does that has closed the most preventable failure category on the list — and has months to do it rather than 60 days after a failure notice.
