FMCSA New Entrant Safety Audit: The 18-Month Compliance Clock and How to Pass It

Every carrier that gets a new USDOT number starts life as a new entrant. For the next 18 months FMCSA watches your operation, and at some point in that window it will run a New Entrant Safety Audit on your records. Pass it and you graduate to regular carrier status. Fail it and don't fix the problems in time, and FMCSA revokes your registration, which puts your trucks out of service. This guide covers how the clock works, what fails a carrier on the spot, and how to have your files ready before the auditor calls.

Who counts as a new entrant

Under 49 CFR Part 385, Subpart D, a new entrant is any motor carrier, domiciled in the US or Canada, that applies for a USDOT number in order to begin interstate operations. That includes the one-truck owner-operator who just got authority, a private carrier hauling its own goods across state lines, and a passenger carrier. Buying a used truck from an established company does not transfer that company's history to you. If the USDOT number is new, you're a new entrant.

The registration you receive is provisional. It becomes permanent only after you pass the safety audit and complete the 18-month monitoring period without your registration being revoked.

The 18-month clock and when the audit happens

The monitoring period runs 18 months from the date FMCSA grants your USDOT registration. The audit itself usually lands well before the end of that window. Federal law calls for it within 12 months of starting operations for property carriers and within 120 days for passenger carriers. Many audits are now done offsite: FMCSA or a state partner contacts you, and you upload documents through a portal. Others take place in person at your place of business.

Some events can pull the audit forward. A crash, a high out-of-service rate at roadside inspections, or a serious violation can trigger an expedited action under §385.308. That can mean an earlier audit and a demand for a written corrective-action response. If you ignore the auditor or refuse to make records available, FMCSA can revoke your registration for that alone (§385.337).

Safety audit vs. compliance review

People mix these up, and the difference matters:

• New Entrant Safety Audit: an educational, pass/fail check of whether you have basic safety management controls in place. It does not produce a safety rating. Your SAFER record shows the carrier as a new entrant, not as Satisfactory, Conditional or Unsatisfactory.
• Compliance Review / comprehensive investigation: a deeper, on-site look at an established carrier's operations under Part 385, Subpart A. This is the process that assigns a Satisfactory, Conditional or Unsatisfactory rating.

So a failed audit doesn't stamp you Conditional by itself. What it does is start the revocation clock. If the problems behind the failure continue, or a crash or bad inspection record follows, FMCSA can open a full investigation. That investigation can end in a Conditional rating, which insurers and brokers check. It can also end in an Unsatisfactory rating, which leads to an out-of-service order. The new entrant period is the cheapest time to get your systems right.

The automatic-failure violations

Appendix A to Part 385 lists specific regulations where a single verified violation fails the audit, no matter how clean the rest of your files are. The ones new carriers trip over most:

• Drug and alcohol testing: having no testing program (§382.115), using a driver before you receive a negative pre-employment drug test result (§382.301), not running random testing (§382.305), or using a driver who refused a test, tested positive or had a 0.04+ alcohol result (§§382.201, 382.211, 382.215).
• Insurance: operating without the required minimum financial responsibility (§387.7). That's $750,000 for general freight in vehicles over 10,001 lbs and up to $5 million for certain hazmat (§387.9).
• Driver qualification: using a driver without a valid CDL, or with a suspended, revoked or disqualified one (§§383.23, 383.37, 383.51, 391.15), or a driver who isn't medically qualified, meaning no current medical examiner's certificate (§391.11(b)(4)).
• Hours of service: not requiring drivers to keep records of duty status (§395.8(a)), or knowingly allowing false logs (§395.8(e)).
• Vehicle maintenance: running a vehicle that was placed out of service before it was repaired (§396.9(c)(2)), not correcting defects a driver reported on an inspection report (§396.11), or using a vehicle without a current periodic (annual) inspection (§396.17).

The auditor also looks at your overall controls across driver qualification, HOS, maintenance, controlled substances, insurance, crash records and hazmat. Widespread gaps can fail an audit even when no single automatic-failure violation is found.

What happens when you fail: the notice and corrective-action window

If you fail, FMCSA sends a written notice listing the violations and the date your registration will be revoked unless you act. Property carriers get 45 days from the notice and passenger carriers get 15 days to submit evidence that the problems are fixed (§385.325). Use the deadline printed on your notice, not a number you heard secondhand. Expedited-action letters and some state-issued notices can set shorter response times.

A corrective action plan that works is specific. It shows what failed, what you changed, who is responsible, and proof that the change is live. Good proof includes:

• A signed consortium/TPA enrollment and the random-selection roster
• A negative pre-employment result dated before each driver's first trip
• Completed driver qualification files
• An ELD account showing drivers logging
• Annual inspection reports for every unit
• A written DVIR repair procedure

"We will do better" gets rejected.

If FMCSA accepts the plan, the revocation is cancelled and the monitoring period continues. If you miss the deadline or the plan is rejected, your new entrant registration is revoked. You must stop interstate operations and reapply as a new entrant, which restarts the 18-month clock. Before reapplying, you'll have to show the problems were fixed. You can also ask for administrative review if you believe FMCSA made an error (§385.329). That isn't a way to buy time.

Preparation checklist: have this ready before the call

1. Drug and alcohol program. Join a consortium, write your testing policy and get each driver's signed receipt. Run pre-employment Clearinghouse full queries and keep negative pre-employment results on file before first dispatch. See our Clearinghouse guide.
2. Driver qualification files for every driver: application, MVR, road test or CDL equivalent, previous-employer safety checks, annual review, and a current medical card with a National Registry verification. See medical card renewal timelines.
3. Hours of service. A registered ELD, six months of retained logs and supporting documents (fuel receipts, bills of lading), and a process for reviewing logs against them. See the HOS compliance guide.
4. Vehicle files for each power unit and trailer: identification, annual inspection reports, maintenance and repair records, and DVIRs showing defects were repaired and certified.
5. Insurance. Confirm your MCS-90 or BMC-91 filing shows active on FMCSA's Licensing & Insurance site, and keep the policy in the office.
6. Accident register covering the past three years, even if it's empty.
7. Registration basics. A current BOC-3, UCR and an accurate MCS-150 mailing address and email, so the audit notice actually reaches you.
8. Run a mock audit at month 3. Pull one driver file, one week of logs and one truck file, and check each against the list above. Then fix what's missing while it's still cheap.

FAQ

Can I be audited after month 12?

Yes. The 12-month and 120-day targets are what FMCSA aims for, not your protection. Audits can come any time in the 18-month window, so your files need to be audit-ready from your first load.

Does a passed audit give me a Satisfactory rating?

No. You'll show as "not rated" until FMCSA does a compliance review. Not rated is normal and acceptable to most shippers and brokers.

What if I haven't started operating yet?

Tell FMCSA when they contact you. If you never begin interstate operations, update your MCS-150 status. Don't leave an active number idle and unanswered.
