When your liability filing shows as cancelled

A cancellation on your federal insurance record is a specific document with a specific clock attached to it. It is not a statement that you have no insurance, and it is not always bad news — a routine change of insurer produces one. Here is what the form is, what the thirty days mean, what it touches on your operating authority, and what the public record genuinely proves.

What you are actually looking at

The form is a BMC-35, and its full title is "Notice of Cancellation Motor Carrier Policies of Insurance under 49 U.S.C. 13906". Two things follow from that title:

It is a notice, not a policy. It records that a party has told FMCSA a filing is being withdrawn.
It cancels the filing, which is the certificate the insurer lodged with the agency. It is a federal record event.

The equivalent form for a surety bond is a BMC-36. If you hold broker authority, a cancellation against your $75,000 broker bond arrives as a BMC-36 and has nothing to do with your trucks — see the five forms that live in the same file.

The thirty-day clock, and when it starts

49 CFR 387.313(d) sets the notice period, and is precise about the start date:

"surety bonds, certificates of insurance, and other securities or agreements shall not be cancelled or withdrawn until 30 days after written notice has been submitted to [FMCSA] on the prescribed form (Form BMC-35 … and BMC-36 … as appropriate) by the insurance company, surety or sureties, motor carrier, broker or other party thereto… which period of thirty (30) days shall commence to run from the date such notice on the prescribed form is filed with FMCSA"

49 CFR 387.313(d)

The clock runs from the date the notice reaches FMCSA — not the date the insurer decided, not the date a letter was posted to you, and not the date of any underlying policy event. That is why the filing date on the record is the date that matters when you are working out where you stand.

A replacement filing ends the old one immediately

The thirty days are not a waiting period you have to sit through. 387.313(e) provides for termination by replacement:

"Certificates of insurance or surety bonds which have been accepted by the FMCSA under these rules may be replaced by other certificates of insurance, surety bonds or other security, and the liability of the retiring insurer or surety… shall be considered as having terminated as of the effective date of the replacement"

49 CFR 387.313(e)

So a normal change of insurer generates a cancellation and a new certificate, and the record shows both. A cancellation with a replacement behind it is housekeeping. A cancellation with nothing behind it is the situation the next section is about.

Why the filing is tied to operating authority

The filing is not paperwork alongside your authority — under 49 CFR 387.301(a)(1) it is a condition of it. The regulation says no certificate shall be issued to a for-hire carrier:

"…or remain in force unless and until there shall have been filed with and accepted by the FMCSA surety bonds, certificates of insurance, proof of qualifications as self-insurer, or other securities or agreements, in the amounts prescribed in § 387.303"

49 CFR 387.301(a)(1)

And 387.301(c), headed "Continuing compliance required", states that accepted security "shall remain in effect at all times". The words doing the work are remain in force and at all times. An accepted filing is what keeps the authority alive, continuously — which is the same principle that makes a filing run indefinitely until cancelled, covered in why your filing anniversary is not a renewal date.

What a cancellation on the record does not prove

This matters if you are reading your own record, and it matters more if you are reading somebody else's:

It does not prove a carrier is uninsured today. The cancelled filing may have been replaced the same day under 387.313(e). You have to look for what came after it, not just at it.
It does not prove the policy was cancelled. The form cancels a filing. An insurer that stops filing for a carrier it still covers produces the same record.
It does not tell you why. There is no reason code on the form. Non-payment, a mid-term insurer change, a switch to self-insurance and an administrative correction all look identical here.
It may not be the whole history. Of the 9,185 BMC-35 rows in the public file on 30 July 2026, 9,169 — 99.8% — carry a transaction date in 2026. The published cancellation table behaves as a recent window, not a complete archive, so the absence of an old cancellation is not evidence that none happened.

Those 9,185 rows belong to 4,368 distinct USDOT numbers, so a carrier that appears here typically has more than one — consistent with layered coverage being cancelled certificate by certificate. Dataset c5y8-a4uz, queried 30 July 2026.

Reading your own record, in order

Find the cancellation and note its date. That date starts the thirty days under 387.313(d).
Look for a later filing. A BMC-91X or BMC-91 with an effective date on or after the cancellation is a replacement, and 387.313(e) treats the old certificate as terminated from that date. If one is there, the record is telling you the coverage moved, not that it stopped.
Check the form code before you worry. A BMC-36 is a bond cancellation, and a BMC-34 line is cargo. Neither is your public liability filing.
Confirm against FMCSA directly. The Licensing & Insurance system publishes the filing history for your USDOT or docket number, and it is the same source every third party is reading.
Take any discrepancy to the party that filed it. Only the insurer or surety can amend, withdraw or replace a certificate it lodged. Your agent of record is the fastest route to that conversation. Nobody else — including us — can change what the federal record says.

See your filing history in one place. The free lookup reads the public FMCSA files live and shows the filings on your USDOT number — form code, insurer, filed limit, policy number and date — so you can see whether a cancellation has a replacement behind it.
