How do I keep my MC authority active?
Keep the required liability insurance on file with FMCSA without gaps, keep a valid BOC-3 process agent filing, update your MCS-150 every two years and whenever your information changes, and register for UCR each year. Stay enrolled in a drug and alcohol testing program and keep your safety records clean, because a lapse in any of these can lead to revocation, deactivation or brokers refusing to load you.
Getting your authority is the first hurdle. Learning how to keep your MC authority active is what lets you keep hauling. Most revocations and deactivations come from missed filings, not bad driving, and every one of them is avoidable with a simple calendar.
Authority status vs. USDOT status
Two records matter, and they can fail separately:
- USDOT number: your carrier registration. It can be deactivated, for example if you miss your biennial MCS-150 update.
- Operating authority (MC number): permission to haul regulated freight for hire across state lines. It can be revoked, most often for insurance or process agent problems.
Brokers check both. A truck with an active USDOT number but revoked authority cannot legally haul most interstate brokered freight.
The filings that keep you active
1. Liability insurance on file
Your insurer files proof of coverage with FMCSA (commonly a BMC-91 or BMC-91X form for liability). If the policy is cancelled, the insurer notifies FMCSA, and if no new filing arrives before the cancellation date, your authority can be revoked.
- Pay premiums on time and set up auto-pay if you can.
- When switching insurers, make sure the new filing is in place before the old one cancels.
- Keep cargo coverage too. It is not always required by FMCSA for general freight, but most brokers require it. Ask your insurance agent what limits brokers in your freight usually expect.
2. BOC-3 process agent filing
A BOC-3 names a process agent in each state where you operate. Without it, new authority will not be granted, and a missing or cancelled BOC-3 can put existing authority at risk. Read BOC-3 filing explained.
3. MCS-150 biennial update
Every carrier with a USDOT number must update its MCS-150 every two years, even if nothing changed. The filing month and year are based on the last two digits of your USDOT number:
- The last digit sets the month (1 = January, 2 = February ... 9 = September, 0 = October).
- The next-to-last digit sets the year: odd digit, file in odd-numbered years; even digit, file in even-numbered years.
Missing it can lead to deactivation of your USDOT number and civil penalties. Also update the MCS-150 whenever your address, phone, email, number of trucks or mileage changes. Confirm the current schedule on FMCSA's website.
4. UCR registration
Most interstate carriers, brokers and freight forwarders must register for the Unified Carrier Registration program every year. Many states enforce it at roadside. See our UCR registration guide.
5. Drug and alcohol program and Clearinghouse
CDL drivers in safety-sensitive jobs need a DOT drug and alcohol testing program. An owner-operator with their own authority usually joins a consortium. You also need to be registered in the FMCSA Drug and Alcohol Clearinghouse and run the required queries.
6. Taxes and registration
These do not keep the MC itself active, but you cannot run legally without them:
- Form 2290 (HVUT) each tax year. See how to file Form 2290.
- IRP apportioned plates and IFTA quarterly fuel tax returns.
A simple compliance calendar
| When | Task |
|---|---|
| Every quarter | IFTA return; review insurance billing; check FMCSA status page |
| Every month | Review new roadside inspections and DataQs status |
| Each year (by your state's IRP date) | IRP renewal |
| Each year (by IRS deadline) | Form 2290 and stamped Schedule 1 |
| Each year (before enforcement starts) | UCR registration |
| Each year | Annual vehicle inspections; driver MVR review and Clearinghouse query |
| Every 2 years (your USDOT month) | MCS-150 biennial update |
| As needed | MCS-150 update for any change; new BOC-3 if your agent changes |
Put each date in your phone calendar with a two-week reminder.
The first 18 months of a new authority
New carriers are in the New Entrant Safety Assurance Program for their first 18 months. FMCSA conducts a safety audit, usually within the first 12 months, to check records like driver qualification files, hours of service, maintenance, drug and alcohol testing and insurance. Certain violations are treated as automatic failures. Our guide to the new entrant safety audit explains how to prepare.
Warning signs your authority is at risk
- A letter or email from FMCSA about a missing filing or upcoming revocation.
- An insurance cancellation notice for non-payment.
- Your process agent company closing or cancelling service.
- A broker setup rejected for "authority inactive" or "insurance not on file."
- Your USDOT status showing "inactive" on the public lookup.
Act on any of these the same day. Most problems are much easier to fix before the revocation date than after.
If your authority was revoked
Reinstatement usually means fixing the cause (new insurance filing, new BOC-3, updated MCS-150), filing the reinstatement request and paying FMCSA's fee. Brokers often see the gap and may ask questions. If your authority has been revoked for a long time, or other problems exist, talk to FMCSA directly or to a compliance professional about your options.
Also protect your FMCSA login. Keep your portal access, email and phone on file current, because FMCSA notices go there. Watch for scam emails and calls claiming to be FMCSA and asking for payment.
This is general information, not legal advice. Fees, forms and procedures change, so confirm current requirements with FMCSA.

Frequently asked questions
What happens if my trucking insurance lapses?
When an insurer cancels a policy, it notifies FMCSA, and if no replacement filing is received before the cancellation takes effect, FMCSA can revoke your operating authority. Reinstating usually requires new insurance filings and a fee, and brokers will see the gap.
Can I keep my authority if I park my truck for a few months?
Your authority generally stays active as long as the required filings stay current. If you drop insurance while parked, the authority can be revoked. Ask your insurance agent about options for parked trucks and check FMCSA's process for voluntarily making authority inactive.
How do I check my authority status?
Look up your USDOT number on FMCSA's public carrier lookup pages, which show authority status, insurance on file and BOC-3 status. Brokers check the same data, so look at it the way they will.
Is the MC number going away?
FMCSA has announced plans to move to the USDOT number as the single identifier for carriers. Timing and details can change, so check FMCSA's announcements and keep both numbers on your paperwork until the change is in effect.
