What to Do After Getting Your MC Authority

Last updated: October 20, 2026 · Sources: eCFR Title 49 (as of Oct. 2026), FMCSA

Quick answer: After FMCSA grants your authority, confirm your insurance and BOC-3 show on file, pay UCR, join a drug and alcohol testing consortium, build a driver qualification file for every driver (including you), set up an ELD, mark your trucks, and start keeping audit-ready records. FMCSA monitors new carriers for 18 months and generally audits within the first 12.

Getting the authority letter feels like the finish line. It's actually the start of the New Entrant Safety Assurance Program, an 18-month monitoring period (49 CFR 385.307). Everything below is something an auditor can ask to see later, so set it up before or alongside your first load.

Step-by-step: the first things to do

1. Confirm insurance and BOC-3 are on file

FMCSA will not grant authority until your required insurance is on file, and once granted you must keep proof of insurance and your process-agent designation (BOC-3) on file "to avoid revocation proceedings" (FMCSA Insurance Filing Requirements). Look yourself up on FMCSA Licensing & Insurance and check that the insurer, effective date and your legal name match exactly. → See insurance requirements for new authority and BOC-3 explained.

2. Register and pay UCR

Unified Carrier Registration is annual and must be complete before January 1 of the registration year. For 0–2 trucks the fee is $46 for 2026 and $55 for 2027 (49 CFR 367.40/367.50 as amended at 91 FR 56063). Use the official site, ucr.gov. → UCR due dates and fees.

3. Set up your drug and alcohol program

If you or your drivers need a CDL, you're covered by Part 382 (49 CFR 382.103). Owner-operators must be in a random pool of two or more, which in practice means joining a consortium/third-party administrator (C/TPA). You need a verified negative pre-employment drug test before driving (382.301), a written policy (382.601), and a Clearinghouse pre-employment full query (382.701). Not having a testing program or a random program is an automatic failure at the safety audit (385.321).

4. Build a driver qualification (DQ) file for every driver

Yes, including yourself. The file includes the application, motor vehicle record, road test or equivalent, medical certificate (max 24 months, 391.45), annual review, and prior-employer inquiries (391.51, 391.21, 391.23, 391.25).

5. Set up hours of service and an ELD

Most interstate drivers need an ELD unless an exception applies, such as logs required no more than 8 days in any 30-day period, driveaway-towaway, or vehicles manufactured before model year 2000 as shown by the VIN (395.8(a)(1)(ii)). Keep the ELD instruction packet and 8 days of blank graph-grids in the truck (395.22(h)). Keep records of duty status 6 months (395.8(k)). FMCSA periodically revokes devices (for example, five on Aug. 6, 2026, with replacement required before Oct. 6, 2026, and more since), so check that your device is still listed at eld.fmcsa.dot.gov. If you're still choosing a device, one option is Motive.

6. Mark your trucks

Both sides of each power unit: your legal or single trade name and "USDOT" plus your number, in contrasting letters readable from 50 feet in daylight (49 CFR 390.21T).

7. Start a maintenance file and daily DVIRs

Systematic inspection and maintenance (396.3), driver vehicle inspection reports when defects are found (396.11), and an annual inspection for every unit, with proof on the vehicle (396.17). Using a vehicle that hasn't had its periodic inspection is an automatic-failure item when found in 51% or more of examined records (385.321).

8. Sort out IFTA, IRP and Form 2290

If your trucks are over 26,000 lb or have three or more axles and cross state lines, you'll generally need IFTA and IRP through your base state. Trucks 55,000 lb and up generally owe the IRS heavy vehicle use tax on Form 2290 (IRS Instructions, Rev. 07/2026).

9. Calendar your MCS-150 biennial update

Your USDOT number's last digit sets the month and the next-to-last digit sets odd or even years (390.19T(b)). The update is free with FMCSA.

10. Get ready for the safety audit

The audit reviews DQ files, hours of service, maintenance, the accident register and drug and alcohol testing (385.311). → New entrant safety audit checklist.

A note on brokers and new authorities

This part comes from industry practice, not regulation. Many brokers set their own minimum "authority age," often 90 days or more, and new carriers say so all the time on r/Truckers and r/FreightBrokers. Clean roadside inspections and complete paperwork help. Load boards are one way to find freight while you build history. One option is LoadMaxer.

FAQ

How long is a carrier considered a "new entrant"? 18 months of new entrant monitoring that begins once the carrier has met its pre-operational requirements (49 CFR 385.307).

When will FMCSA do my safety audit? FMCSA says generally within the first 12 months of operation. The rule says the audit happens once there are generally at least 3 months of records to review (385.307).

Do owner-operators need drug testing? Yes, if you drive a CMV that requires a CDL. You must be in a random pool of two or more covered drivers, usually through a consortium (382.103, 382.305).

Is the MCS-150 update free? Yes, filing it with FMCSA is free. Private sites may charge, but using them is optional.

Do I still have an MC number under Motus? Yes. Existing USDOT and MC numbers didn't change when FMCSA moved registration to Motus in May 2026 (legacy registration tools were retired May 14, 2026). Phasing out MC numbers has only been proposed.
