DOT Audit Preparation
DOT audit preparation for new entrants: a mock audit before the real one
New carriers get a safety audit within their first months of operation, and FMCSA's own published reviews show that most investigations find at least one violation. The carriers that do fine are the ones whose records were organized before anyone called. Software keeps your audit files current and watches your safety data every day; a person reads what it finds and walks the file with you before an investigator does.
Audit preparation, and the support around it
New Entrant Audit prep
We build the four files the auditor asks for, run the 16 automatic-fail checks, fix what is broken and hand you the binder. It is part of onboarding on a membership, or $549 on its own.
Safety-score monitoring
We watch your public safety data for new inspections and violations, and flag changes in plain language.
DataQs challenge drafting
If a violation on your record looks wrong, we review it first and tell you honestly whether it is worth challenging. If it is, drafting is $99 for members and $169 otherwise. You review and submit.
Ongoing audit-ready files
Members keep an organized vault year-round and the system re-checks it as records change, so audit prep is a review, not a scramble.
Who it's for: Carriers in their first 18 months of authority, and any fleet of 1 to 6 trucks that wants its records to look the way an auditor expects. Fleets of 7 or more are priced by conversation.
What a mock DOT audit covers
A mock audit is the new entrant safety audit run early, against your own records, by us instead of an auditor. It follows the audit's own scope and scoring:
- The records the audit samples under 49 CFR 385.311: driver qualification, hours of service, vehicle maintenance, the accident register, and drug and alcohol testing.
- The sixteen violations in 49 CFR 385.321(b) that fail the audit on their own, checked one by one, with the fix for anything that would fail.
- The six factors in Appendix A to part 385 that the audit scores, so you know where points would land before anyone assesses them.
- The gaps named in writing: what we found, what was fixed, and what is still yours to do, handed over with the organized binder.
What we will not promise
Nobody can guarantee how an audit turns out, and we do not. Preparation means the records exist, are current and can be produced on request; the findings are the auditor's. We are not a law firm and do not represent you, and if your situation needs a transportation attorney we say so.
The 12 months and the 18 months are different things
The new entrant monitoring period runs 18 months from registration under 49 CFR 385.307, and the regulation says the safety audit is conducted once you have been operating long enough to have sufficient records to review. The 12-month figure is FMCSA's program guidance: the agency tells carriers to expect the audit within their first 12 months of operating. Guides routinely blur these together, which leaves carriers either expecting the audit too late or assuming they are clear at month 12 when monitoring continues.
Which violations fail an audit outright, and what we do about them
Most audit findings are graded. Sixteen, listed in 49 CFR 385.321(b), are not: a violation in any of them fails the audit outright. They span drug and alcohol testing, CDL requirements, insurance, driver qualification, hours of service and vehicle records, and operating a vehicle declared out of service.
They are not all single-occurrence. Failing to implement a testing program under 382.115, using a driver without a valid CDL, and operating without required financial responsibility each fail on one instance. Failing to maintain driver duty records under 395.8(a) requires violations in 51% or more of the records examined.
Audit prep runs every one of the 16 against your records before an auditor does. Want a first read yourself? Our free audit readiness score checks the ones a one-truck carrier is most likely to trip, in 13 questions, and the new entrant safety audit checklist lists every document with its regulation. Already failed? The help article on the 60-day correction window covers the clock.
What this means in practice
Four of the 16 sit in drug and alcohol testing and four in CDL requirements. For a one-truck carrier, that means the two things most likely to end your authority in year one are not being enrolled in a random testing pool and a lapse in medical qualification, both entirely preventable, both invisible until someone checks.
If you fail: the clock that starts immediately
FMCSA must notify you in writing no later than 45 days after the audit that your registration will be revoked and operations placed out of service unless you take specified remedial action. From that notice, 49 CFR 385.319(c) gives most new entrants 60 days to correct. Passenger carriers for direct compensation and hazmat carriers get 45.
Correct it acceptably inside the window and FMCSA confirms in writing that registration will not be revoked. Miss it and 385.325 makes the out-of-service order effective on day 61, or day 46 for the shorter group, after which you may not operate in interstate commerce. If that has already happened, see reinstatement after a failed audit.
The 15-day detail inside the 90-day appeal
You have 90 days to request administrative review under 385.327. But to get a decision before the operating prohibition takes effect, the request must be filed no later than 15 days from the date of the notice. Carriers who read only the 90-day figure lose the ability to keep running while they argue.

What happens if you skip it
A failed audit is survivable and routinely survived, the carriers who lose their authority are usually the ones who missed the correction window, not the ones who failed the audit.
- Registration revoked and an out-of-service order effective on day 61 (or day 46 for passenger and hazmat carriers).
- You may not operate in interstate commerce on or after that date: this is an operating bar, not a fine.
- Reapplication is possible no sooner than 30 days after revocation, and it restarts the 18-month monitoring cycle from scratch.
- The gap in authority is visible to brokers and insurers long after the paperwork is resolved.

Common questions
How do I prepare for a DOT audit?
Build the records the audit samples before anyone asks: a qualification file on every driver, yourself included; proof of your random testing pool and every result; your Clearinghouse registration and queries; records of duty status; each truck's annual inspection and maintenance file; the accident register, even if it is empty; and proof of insurance. Then check them against the sixteen violations in 49 CFR 385.321(b) that fail the audit on their own. That is what a mock audit does, and our free printable checklist lists every item.
When do new carriers get audited?
FMCSA's new entrant program runs 18 months from registration (49 CFR 385.307), and the agency's guidance is to expect the safety audit within your first 12 months of operating. Those two numbers get conflated constantly, the 12 months is FMCSA's guidance on when to expect the audit; the 18 months is the monitoring period the regulation sets.
What fails a new entrant audit automatically?
49 CFR 385.321(b) lists 16 violations that fail the audit. Most fail on a single occurrence, no drug and alcohol testing program, using a driver without a valid CDL, operating without the required insurance, using a medically unqualified driver, operating a vehicle declared out of service. A few, such as failing to maintain driver duty records under 395.8(a), require a 51% violation threshold instead.
What happens if I fail the new entrant safety audit?
FMCSA notifies you in writing no later than 45 days after the audit that your registration will be revoked unless you take corrective action. Most carriers get 60 days from that notice; passenger and hazmat carriers get 45. Fix it inside that window and you continue operating.
What if I do not correct it in time?
Under 49 CFR 385.325, registration is revoked and an out-of-service order takes effect, day 61 for most carriers, day 46 for passenger and hazmat. You may not operate in interstate commerce on or after that date. You can reapply no sooner than 30 days after revocation under 385.329T, which restarts the 18-month monitoring cycle.
Can I appeal?
You can request administrative review from the Field Administrator of the FMCSA Service Center under 385.327, within 90 days of the notice. But if you want a decision before the prohibition takes effect, file within 15 days. That timing is what actually matters and it is easy to miss.
Can TenFour attend my audit?
We support you on audit day as part of audit prep, making sure the right documents are ready and that you understand what is being asked. We do not provide legal representation, and if your situation needs a transportation attorney we will say so.
What is DataQs?
DataQs is the federal system for requesting review of data on your safety record. We look at the violation first and tell you whether a challenge is worth filing; if it is, drafting is $99 for members and $169 otherwise, and you submit the request from your own DataQs account. We cannot promise a result; nobody honestly can.
How much does audit preparation cost?
New Entrant Audit prep is part of onboarding on a TenFour membership. Nothing extra to buy. On its own, for a carrier not on a plan, it is $549: the four files the auditor asks for built and checked, the 16 automatic-fail items run, the binder handed over. That amount is credited to a plan you start within 60 days.
