Every new interstate motor carrier enters a 12-month probationary “new entrant” period the day their MC number activates. Somewhere inside that window — typically months 3 through 9 — an FMCSA safety investigator (SI) or state contractor (MCSAP) will schedule an audit under 49 CFR § 385.301.
The audit is not optional. The audit is not a friendly check-in. And under 49 CFR § 385.323, there are 20 violations that result in automatic failure — most of which are not “you did the wrong thing,” they are “you did not do the thing at all.”
Below is the checklist auditors actually work through. Walk it yourself, in order, before they walk it for you.
◆ How to use this checklist
For each item: ☐ if you have it, ☒ if you don't.
What the auditor opens first.
Sixteen items. Six of them are on the automatic-failure list — those are marked.
- 01
General company information
USDOT, MC, EIN, registered agent, business address. Verify all four match across FMCSA, IRS, and state filings. Mismatches trigger follow-up questions you don't want.
- 02
Operational classification
Authorized carrier (motor carrier of property), broker, or both. Hazmat or non-hazmat. Interstate or intrastate. Auditor cross-references against your URS application — discrepancies are an automatic write-up.
- 03§ 385.323
Driver Qualification (DQ) file — completeness
§ 391.51 requires 11 specific documents per driver. Missing a DQ file entirely is on the automatic-failure list. Application (§ 391.21), inquiry to previous employers (§ 391.23), MVR (§ 391.25), road test certificate (§ 391.31), medical examiner's certificate (§ 391.43), CDL copy.
- 04
DQ file — driver investigation history (§ 391.23)
This is the single most-missed item. You must contact previous DOT employers in writing for any safety-sensitive employment within the last three years. Auditors want to see the request and the response — or proof of a 30-day good-faith attempt.
- 05§ 385.323
Driver Clearinghouse queries (§ 382.701)
Pre-employment full query before the driver performs a safety-sensitive function. Annual limited query for every driver every 12 months. Missing the pre-employment full query is automatic failure in 2024+.
- 06§ 385.323
Drug & alcohol testing program (Part 382)
Written DOT-compliant policy. Pre-employment, random, post-accident, reasonable-suspicion, return-to-duty, and follow-up procedures all documented. C/TPA agreement on file if you outsource (most small fleets do). Random selection records that show you met the annual rate.
- 07§ 385.323
Driver medical certificates
Current certificate for every driver, issued by a Certified Medical Examiner from the National Registry. Expired certificate while the driver is operating = automatic failure.
- 08
Hours of Service records (Part 395)
ELD records for the last six months (or paper logs where exempt). Retained per § 395.8(k). Auditor will sample 7–14 days and look for falsification, missing logs, or exceeding the 11/14/70 limits.
- 09
ELD self-certification & registration
Your ELD must appear on FMCSA's registered ELD list. You must have the user manual, malfunction reporting procedure, and instructions for transferring records during a roadside inspection — in the truck.
- 10§ 385.323
Vehicle maintenance file (§ 396.3)
Every power unit and trailer must have a maintenance file showing: identification, scheduled inspection history, brake repairs, tire repairs, and any out-of-service repairs. No maintenance file = automatic failure.
- 11
Annual vehicle inspection (§ 396.17)
Every CMV inspected at least once every 12 months by a qualified inspector. Sticker on the truck, report in the maintenance file.
- 12
Driver Vehicle Inspection Reports (DVIRs) (§ 396.11)
Daily post-trip DVIRs retained for 3 months. Any “no defects” trend across an entire fleet is itself a red flag — auditors expect to see real defects reported and corrected.
- 13
Accident register (§ 390.15)
A register listing every DOT-recordable accident (death, injury requiring transport, or disabling tow-away) for the last 3 years. Even if you have had zero accidents, the empty register itself must exist.
- 14§ 385.323
Insurance and financial responsibility (§ 387.7)
Active BMC-91 (or BMC-91X) on file with FMCSA matching your operating classification. MCS-90 endorsement where applicable. Certificate of insurance showing the required minimums.
- 15
Hazmat program (if applicable)
Drivers HM-trained per § 172.704. Shipping papers, placarding, emergency response info, registration with PHMSA. Skip if you're non-hazmat.
- 16
Cargo securement & loading procedures
Knowledge of § 393 cargo securement standards. Training records for drivers who load or secure cargo.
◆ The pattern across hundreds of audits ◆
Automatic failure isn't usually because you did the wrong thing. It's because you didn't do the thing at all. The DQ file isn't sloppy — it doesn't exist. The maintenance file isn't bad — there is no file.
Your “do not skip” list.
§ 385.323 lists 20 specific violations that fail your audit on the spot. The most common automatic failures for new entrants are listed below — memorize these or print them in the cab.
No general knowledge of the safety regulations.
Operating without insurance meeting § 387.7.
Failure to implement a drug & alcohol testing program.
Using a driver who tested positive or refused and didn’t complete return-to-duty.
Using a driver without a valid CDL.
Operating a vehicle declared out of service.
Failure to require a driver to make a DVIR.
Failure to correct out-of-service defects before operation.
Three possible outcomes.
Pass
Stay in the new-entrant period
At month 12 your status converts to "authorized" with no further action.
Conditional
Corrective action plan
You receive a notice of proposed conditional safety rating under § 385.337 with a CAP and a 60-day window to fix.
Fail
Notice of revocation
FMCSA issues a notice to revoke your new-entrant registration. 60 days to correct under § 385.323(d). Failure to correct ends in revocation + 12-month wait before you can reapply.
The audit is winnable. The carriers who fail are almost never the ones running poorly — they're the ones running fine, who didn't build the paper trail to prove it.
Don't walk into the audit unprepared.
Our DOT audit specialists walk this 16-item checklist with you before FMCSA does — find the gaps, build the missing files, and rehearse the auditor’s questions. Whether you have a letter scheduled or just want a clean dry run before month 6.
