Short answer
When a trucking policy cancels, the insurer files a cancellation notice with the regulator. Federally, a BMC-91X filing cannot be cancelled until 30 days after a Form BMC-35 notice is filed with FMCSA, and FMCSA requires insurance to stay on file to avoid revocation proceedings. In Texas, the insurer files Form K and TxDMV can penalize or revoke your certificate.
- Brokers and onboarding platforms can see a pending cancellation, so loads can dry up before coverage actually ends.
- The fix is a replacement filing from a new insurer effective before the old one cancels. A replacement ends the old filing immediately.
The federal notice rules
There are two clocks, and they are easy to confuse:
- Policy cancellation between you and the insurer. 49 CFR 387.7(b) says policies and endorsements stay in effect until terminated, and cancellation by either the insurer or the carrier takes 35 days' written notice to the other party.
- Cancellation of the FMCSA filing. 49 CFR 387.313(d) says a certificate of insurance on file with FMCSA cannot be cancelled or withdrawn until 30 days after written notice is filed on the prescribed form, Form BMC-35 for insurance. The 30 days run from the date the notice is filed with FMCSA.
The insurer's notice to you is governed by your policy and Texas insurance law. The federal rules above are about what FMCSA and the public see.
| Regulator | Notice form | Notice period | If not replaced |
|---|---|---|---|
| FMCSA (interstate for-hire) | BMC-35 | 30 days from filing with FMCSA (49 CFR 387.313(d)) | Revocation proceedings for failing to keep insurance on file |
| TxDMV (Texas intrastate) | Form K | TxDMV e-mails a notice 30 days before cancellation if your e-mail is on file | Administrative penalties, sanctions or certificate revocation |
What FMCSA and TxDMV do when insurance lapses
FMCSA's insurance filing page says that once authority is granted, carriers "are required to maintain proof of insurance and designation of agents for process on file with FMCSA to avoid revocation proceedings." Under 49 CFR 387.301(c), the security accepted by FMCSA must remain in effect at all times, and under 387.7(a) no motor carrier may operate a vehicle without the required financial responsibility. A revoked authority has to be reinstated (FMCSA lists an $80 reinstatement fee) before you can haul for hire again.
TxDMV says failing to keep continuous proof of insurance in TxMCCS may result in administrative penalties, administrative sanctions, or revocation of your certificate. See what is Texas Form E.
FMCSA also treats operating without required insurance as a trigger for an expedited safety audit of a new entrant under 49 CFR 385.308.
Why loads stop before coverage ends
Pending cancellations are visible. FMCSA's SAFER Company Snapshot links to Licensing and Insurance records showing any pending insurance cancellation, and broker onboarding and monitoring tools watch the same records. Some brokers stop tendering loads once a cancellation notice posts, even though the filing technically has 30 days to run. That is why a nonpayment notice is a freight problem, not just an insurance problem. See trucking insurance non-renewal for the related case where a policy is simply not renewed.
How to avoid a lapse
- Act on the first notice. Most cancellations are for nonpayment and can be cured before the effective date. Call your agent the day it arrives.
- Replace, don't wait. Under 387.313(e), a replacement filing ends the retiring insurer's liability as of the replacement's effective date. Bind the new policy and have the new insurer file effective the same day.
- Check both systems. Confirm the new filing on FMCSA records, and confirm TxMCCS shows "Active" if you run intrastate.
- Send brokers a fresh certificate so their monitoring tools clear the flag.

Do not run during a gap
An uninsured truck is not just a regulatory violation. Any crash during a lapse is a claim against the company with no insurer behind it.
Common questions
If my policy cancels today, is my FMCSA filing gone today?
No. The filing stays on record until 30 days after the BMC-35 notice is filed with FMCSA, unless a replacement filing ends it sooner. Your actual coverage depends on the policy cancellation date.
Can I get my authority back after revocation?
Yes, through reinstatement once insurance and other filings are back on file. FMCSA lists an $80 reinstatement fee.
Who files the cancellation notice?
Federally, the insurer, surety or carrier files Form BMC-35 with FMCSA. In Texas, only the insurer can file Form K with TxDMV.
