New Authority Checklist: Your First 90 Days With an MC Number (2026)

Quick Answer

Your first 90 days with new authority are about building the records FMCSA will audit. Before the first load, join a drug and alcohol consortium, get a negative pre-employment drug test, run a Clearinghouse query, build a driver qualification file, install an ELD, get an annual inspection, and register for UCR. Then keep clean logs, DVIRs, and maintenance files. FMCSA usually audits new carriers within 12 months.

Key Takeaways

• An MC number alone isn't authority to haul. You can operate only after FMCSA issues the authority and your status shows ACTIVE, which requires your insurance and BOC-3 filings on file.
• A CDL driver, including an owner-operator driving for himself, needs a verified negative pre-employment drug test before the first safety-sensitive work (49 CFR 382.301).
• An owner-operator who is the only driver must be in a random testing pool of two or more drivers, which in practice means joining a consortium (49 CFR 382.103(b)).
• Every truck and trailer needs a periodic inspection within the last 12 months, with documentation on the vehicle (49 CFR 396.17).
• FMCSA monitors new entrants for 18 months and conducts the safety audit after generally at least 3 months of operation (49 CFR 385.307), usually within 12 months.

When does a new MC authority become active?

You'll hear "21 days" a lot. That number isn't in the regulations. FMCSA's OP-1 instructions lay out the steps: you get an MC number, your application is published in the FMCSA Register, and a 10-calendar-day protest period starts (49 CFR 365.115).

During that window your insurer files proof of coverage and your process agent files the BOC-3. The OP-1 instructions are blunt: an assigned MC number "does not represent Operating Authority." You can start hauling only after the authority is issued and your status shows ACTIVE.

Since spring 2026, new applications and registration updates run through Motus (motus.dot.gov), FMCSA's replacement for the old URS and Portal. Your USDOT and MC numbers don't change. If you're still in the pre-authority stage, start with our hot shot trucking requirements guide, which covers the startup filings.

What does the new authority timeline look like?

Day 0 is the day your authority goes active. The clock that matters most is the 18-month new entrant period, which starts when you begin operating.

What should you do in your first week with new authority?

Do these before you dispatch the first load. Having no testing program, no random testing, no required insurance, or no annual inspections can each fail the safety audit automatically.

1. Check your status. Confirm the authority shows ACTIVE and your insurance and BOC-3 filings are listed. File the authority letter and the MCS-90 endorsement at your place of business (49 CFR 387.7(d)).
2. Join a DOT drug and alcohol consortium. If you drive a vehicle that requires a CDL, you need a testing program with random testing. A solo owner-operator must be in a pool of at least two drivers.
3. Get a pre-employment drug test. You need a verified negative result before the first safety-sensitive work. A narrow exception exists for drivers already tested in a compliant program (49 CFR 382.301(b)).
4. Register in the Clearinghouse as an employer. Run a full pre-employment query on every CDL driver, yourself included (49 CFR 382.701). FMCSA says an owner-operator registered as an employer must also designate a C/TPA. Our Clearinghouse guide walks through setup.
5. Build a driver qualification file for each driver. It holds the employment application, a motor vehicle record from each state licensing agency, road test certificate or accepted equivalent, and the medical examiner's certificate (49 CFR 391.51). Pull the MVR within 30 days of the driver's start (49 CFR 391.23).
6. Install your ELD and stock the cab. Unless an exception applies, such as logging 8 or fewer days in any 30, or an engine older than model year 2000, every driver must use an ELD (49 CFR 395.8). Keep the data-transfer instruction sheet, the malfunction instruction sheet, and 8 days of blank paper logs in the truck (49 CFR 395.22(h)).
7. Get an annual inspection on every truck and trailer. A used truck's old sticker may not be enough. You need a qualifying inspection within the preceding 12 months and documentation on the vehicle.
8. Register for UCR. The UCR Handbook says the fee is due as soon as you're registered for interstate commerce, and registration for the next calendar year generally opens October 1.
9. Sort out IRP and IFTA if your truck qualifies. Under the IFTA agreement, a qualified vehicle has two axles and over 26,000 lbs, three or more axles, or a combination over 26,000 lbs. Rigs under those thresholds don't qualify. Apply through your base state.

What should you set up in your first 30 days?

Month one is about habits the auditor will check.

1. Keep logs and supporting documents. Retain records of duty status and supporting documents such as fuel receipts and bills of lading for at least 6 months (49 CFR 395.8(k)).
2. Use DVIRs every day. Write up defects and fix them before the truck runs again. Keep repair certifications with the report.
3. Start a maintenance file per vehicle. Record the vehicle ID, scheduled inspection and maintenance items with due dates, and what was done and when. Keep it 1 year, and 6 months after the vehicle leaves your control (49 CFR 396.3).
4. Start an accident register. List every DOT-recordable crash and keep it 3 years (49 CFR 390.15). If you've had none, note that in writing.
5. Check your MCS-150 data. Your legal name, address, phone, and vehicle and driver counts should be right. FMCSA sends new entrant letters to the contact details on file, and the MCS-150 biennial update guide explains when updates are due.
6. Calendar your insurance renewal. Coverage must stay in effect continuously, and cancellation takes 35 days' written notice (49 CFR 387.7). A lapse can lead to revocation of your authority. See new authority trucking insurance for shopping tips.

What should you do in months 2 and 3?

FMCSA's FAQ says new entrants receive a letter explaining what to do next. Open every envelope from FMCSA or your state's enforcement agency.

1. Take FMCSA's free New Entrant online training. It has six self-paced modules, takes about 90 minutes, and covers the safety audit.
2. Audit yourself. Pull 30 days of logs for one driver and check them against fuel receipts. Make sure every DQ file is complete and every med card is current.
3. Review your roadside inspections. FMCSA watches inspection results closely during the 18 months. Fix every cited defect and keep the paperwork.
4. Set reminders for recurring items. Clearinghouse queries (at least once a year per driver), annual MVR reviews, annual vehicle inspections, IFTA quarterly returns, UCR, and your biennial MCS-150 update.

Lucid ELD's Standard plan, for example, puts ELD logs, DVIRs, and IFTA mileage reporting in one app, which keeps several of these records in one place.

What paperwork do brokers ask a new authority for?

None of this is a federal rule. It's standard business practice, and each broker sets its own requirements. A typical carrier setup packet includes:

• Your MC authority letter or certificate
• A W-9 with your legal business name and EIN
• A certificate of insurance listing the broker as certificate holder
• A notice of assignment, if you use a factoring company
• Banking details for payment

Some brokers won't load carriers whose authority is very new, so expect to work with brokers that onboard new carriers.

How do you protect a new MC number from fraud?

FMCSA defines carrier fraud as someone using another carrier's USDOT number without permission, or acting as a broker without registering. Its fraud alerts page lists current scams, including fake Motus sites, fake safety audit requests, and offers to buy or lease authority.

• Sign in only at motus.dot.gov. FMCSA has named lookalike sites sending "Notice of Required Off-Cycle Update" emails.
• FMCSA says it doesn't request credit card numbers by phone or charge for downloadable forms.
• Never sell, rent, or "lease out" your MC or USDOT number. FMCSA says it will inactivate numbers used by anyone other than the assigned legal person.
• Verify every broker's authority in FMCSA's records before you haul, and confirm load details with a known contact.
• Report suspected fraud to the FMCSA Contact Center at 1-800-832-5660.

When will FMCSA do your new entrant safety audit?

FMCSA's New Entrant program page says the audit happens within 12 months after you begin operations. The regulation says FMCSA waits until you have enough records, "generally at least 3 months" (49 CFR 385.307).

Our new entrant safety audit guide covers the 16 automatic-failure violations, the document list, and what happens if you fail.

Educational content, not legal advice. Confirm requirements against current FMCSA regulations and your state's rules.

FAQ

How long after getting an MC number can you start hauling?

You can haul only after FMCSA issues the authority and your status shows ACTIVE. That follows a 10-day protest period after FMCSA Register publication, plus accepted insurance and BOC-3 filings. The often-quoted "21 days" is an estimate, not a rule.

Do I need drug testing if I'm the only driver?

Yes, if your vehicle requires a CDL. A solo owner-operator must be in a random pool of two or more drivers and needs a negative pre-employment drug test before driving (49 CFR 382.103 and 382.301).

Does an owner-operator need a driver qualification file on himself?

Yes. Section 391.51 requires a file for each driver the carrier employs, and an owner-operator is his own company's driver. Keep your application, MVRs, road test or equivalent, and medical certificate in it.

When does a new authority become permanent?

After you complete the New Entrant Safety Assurance Program (49 CFR 365.110). The new entrant period lasts 18 months, and passing the safety audit is part of completing it.

Is the FMCSA safety audit email I got real?

Maybe not. FMCSA's fraud alerts page warns about fake audit requests and fake safety audits. Don't click links; call the FMCSA Contact Center at 1-800-832-5660 to confirm.
