What is a BMC-91 filing?

The BMC-91 is the primary form insurance companies file with FMCSA to prove a motor carrier has liability coverage that meets federal minimums. Most property carriers are filed on BMC-91X, a stackable version that allows layered coverage from multiple insurers. The filing is what makes the MC Authority 'Active' in FMCSA's eyes.

What is a BMC-34 filing?

The BMC-34 is the cargo insurance filing for household goods carriers. It proves the carrier has at least $5,000 per vehicle and $10,000 per occurrence in cargo coverage. Non-household-goods carriers do not need a BMC-34 but still need a BMC-91 for liability.

What happens when an insurer cancels coverage?

Insurers file a K (cancellation) notice with FMCSA that includes an effective cancellation date, typically 30 days forward. FMCSA displays 'Insurance: Pending Cancellation' on the public SAFER snapshot. If replacement coverage does not file before the effective date, the MC Authority moves to 'Revoked' status.

Can I still operate during the 30-day pending cancellation window?

Legally, yes — the policy remains in force through the effective date. Practically, most brokers and load boards flag 'Pending Cancellation' immediately and stop tendering loads. Factoring companies often pause advances. The 30 days are for finding replacement coverage, not for operating without urgency.

Insurance L&I Filings: How a 30-Day Cancellation Notice Kills Your MC Authority

FMCSA's Licensing & Insurance system is the tripwire that converts an insurance hiccup into a revoked MC Authority. Here is how BMC-91 and BMC-34 filings work, what a 'pending cancellation' means, and the exact 30-day clock you are running against.

Published April 24, 20268 min read

Every insurance cancellation letter that lands in a carrier's mailbox also lands, electronically, at FMCSA headquarters in Washington. The agency's Licensing & Insurance (L&I) system exists for one reason: to make sure no motor carrier moves freight without the federally mandated liability coverage. The moment an insurer files a cancellation notice, the countdown is running against the carrier's MC Authority.

The filings that hold your authority together

An active MC Authority depends on two independent filings on record with FMCSA:

BMC-91 or BMC-91X — primary liability coverage. Minimum is $750,000 for non-hazardous property, $1 million for most hazmat, $5 million for certain bulk chemicals. The X version allows stacking layers from multiple insurers.
BMC-34 — cargo coverage for household goods only. Minimum $5,000 per vehicle, $10,000 per occurrence. Non-HHG carriers do not need this filing, though many carry cargo insurance voluntarily.

Both filings are made by the insurance company electronically through FMCSA's L&I system, not by the carrier. The carrier's job is to pay the premium on time and stay in coverage.

The anatomy of a cancellation

When an insurer decides to end coverage — non-payment, underwriting change, non-renewal — three things happen in sequence:

Day 0. Insurer files a K notice (cancellation) with FMCSA through the L&I system. The notice includes an effective cancellation date, by law at least 30 days in the future under 49 CFR 387.313.
Day 0 to 1. FMCSA updates the public SAFER snapshot: "Insurance: Pending Cancellation on {date}." The MC Authority status remains ACTIVE for now.
Day 30. Effective cancellation date passes. If no replacement BMC-91 or BMC-34 has posted, FMCSA flips the MC Authority to REVOKED overnight.

The trap. Brokers see "Pending Cancellation" within 24 hours and often pause tendering. The carrier's cash flow dries up exactly when they need it most to pay the new premium. This is why catching the initial filing within the first day matters so much — 29 days of runway beats 3.

The four common reasons coverage lapses

Non-payment. By far the most common. A missed ACH on the 1st triggers a K notice by the 10th. Most policies allow reinstatement without a new filing if payment clears within the grace period.
Safety-driven non-renewal. After a spike in CSA BASIC percentiles or an at-fault crash, insurers increasingly file non-renewal at the policy anniversary rather than re-quoting. This is the pattern that most often ends in a revoked authority because carriers do not realize they need to shop the market 60 days early.
Carrier self-cancellation. Moving from Insurer A to Insurer B. The new insurer files a BMC-91 before the old one's effective cancellation — in theory. In practice, filing delays of 48 to 72 hours happen, and a carrier with a Thursday effective date whose new filing posts on Monday morning has a 4-day gap that triggers the revocation overnight.
MGA or insurer insolvency. Rare, but when it happens the cancellation is immediate under emergency rules. The state department of insurance usually directs affected carriers to replacement markets, but the L&I timeline is unforgiving.

The first 24 hours after a cancellation notice

Verify the reason. Pull the policy declarations page. Was it non-payment (fixable) or non-renewal (shop the market)?
If non-payment: call the insurer, pay with wire or card, obtain a rescission of the K notice. The insurer files it with FMCSA and the pending cancellation clears within 24 hours.
If non-renewal: contact three brokers in parallel the same day. Carriers with clean records replace coverage in 3 to 5 days; carriers with CSA issues should budget 10 to 15 days and start at day 1, not day 20.
Watch SAFER hourly. The moment the replacement BMC-91 posts, SAFER clears the pending status. If it has not cleared 24 hours after your new insurer confirms filing, escalate to the insurer's filings department.

Reinstatement after a REVOKED status

If the effective date slides past and the authority revokes, reinstatement is still possible but substantially more expensive:

Re-file the BMC-91 (new insurer or current one).
Pay FMCSA's reinstatement fee (currently $80 per MC).
File OP-1 re-registration. Processing takes 2 to 4 weeks.
During the gap, the carrier has no lawful authority to move interstate freight. Running without authority risks civil penalties up to $16,000 per violation and out-of-service orders on every truck.

How Deadline Safe monitors L&I

FMCSA L&I publishes insurance status in the public SAFER snapshot and in QCMobile fields. We pull the insurance fields every day and flag any change on the Insurance card of the dashboard:

Effective date changes (new policy filed)
Cancellation pending, with exact effective date
Filing rejected by L&I (clerical error; needs insurer fix)
Authority status flipped from ACTIVE to anything else

Alerts go out by email within minutes on paid plans, and once a day on Free. The goal is the same in every plan: collapse the gap between the K notice and your awareness from 29 days to less than one.
