BMC-91 and BMC-91X filings explained: how federal insurance filings create sales leads

Every for-hire motor carrier operating under federal authority must prove to FMCSA that it carries liability insurance. That proof is not the policy itself — it is a filing the insurance company submits directly to FMCSA on the carrier's behalf. The two filings that matter most are the BMC-91 and the BMC-91X, and understanding how they work explains one of the most reliable prospecting systems in commercial insurance.

What the forms actually certify

A BMC-91 certifies that the insurer has issued the carrier a policy meeting the federal minimum for bodily injury and property damage (BIPD) liability — $750,000 for general freight, higher for passenger carriers and hazmat. The BMC-91X does the same job when coverage is split across multiple insurers or written with underlying limits; in practice it is the form you will see most often on small and mid-size carriers.

The filing is what keeps the carrier's operating authority alive. No active BIPD filing means FMCSA revokes authority, and a carrier without authority cannot legally haul a single load. This is why an insurance filing problem is an existential business problem for a trucking company, not a paperwork inconvenience.

The 30-day rule: 49 CFR 387.313

Here is the part that creates a market. Under 49 CFR 387.313(d), an insurer that wants to cancel a filed policy cannot just stop coverage. It must submit a cancellation notice to FMCSA — form BMC-35 for most filings — at least 30 days before the cancellation takes effect. The notice includes the exact date coverage dies, called the cancellation effective date.

That notice is a public record from the day it is filed. FMCSA publishes it in its open data feeds along with the carrier's USDOT number, the insurer's name, the policy number, and the effective date of the cancellation. Roughly 150 new cancellation notices appear on a typical business day — thousands of carriers at any moment are inside their 30-day window.

Think about what that window means from the carrier's side. Their insurer has formally told the government it is walking away. In at most 30 days they either have replacement coverage filed or their trucks are legally parked. They are, by federal mandate, shopping for insurance right now.

Why cancellations happen — and why they're good leads

Policies get cancelled mid-term for non-payment, for underwriting reasons after a loss, because the insurer is leaving a state or a class of business, or because the carrier found cheaper coverage and the old policy is being replaced. The public record distinguishes genuine cancellations from replacements, which matters: a carrier whose policy is being replaced already solved their problem, while a carrier with a true pending cancellation has an unsolved one with a deadline.

For an agent, a carrier inside the 30-day window is the opposite of a cold call. You know they need coverage, you know exactly when, you know who is dropping them, and you know the coverage type. A closed trucking liability policy typically pays $1,500–4,000 a year in commission, and carriers that move once often move their whole account.

How to find BMC-35 cancellation notices

Before May 2026, the standard answer was FMCSA's L&I Public search. That system was retired when FMCSA moved to its new MOTUS registration platform, and the data now lives in MOTUS-era datasets on data.transportation.gov — public and free, but with undocumented schema changes and a frozen legacy feed sitting next to the live one, waiting to mislead anyone who queries the wrong dataset.

You can work the data yourself if you have technical help: pull the insurance history dataset daily, filter to cancellation filings with future effective dates, exclude replacements, and join against the carrier census for phone numbers. That is precisely the pipeline XDate Alert runs every afternoon, with monitoring that checks the feed is actually fresh before anything is sent. Subscribers get the new filings for their states the same business day they land, with contact info and days-remaining attached.

However you source them, the discipline that converts is speed. A BMC-35 filed yesterday is a conversation; one filed three weeks ago is a carrier that has already signed with whoever called first. The rule that creates the lead also starts the clock.
