BMC-91 vs BMC-91X: The Insurance Filing Difference That Decides Whether You Get Paid

A broker I used to run loads alongside got wiped out two years ago. Not by a bad carrier exactly — by a bad insurer.

He'd done everything right on paper. Pulled the carrier, checked SAFER, verified authority, got a COI showing $1M BIPD. The carrier had a clean inspection history and had been on his preferred list for eight months. Then one of their drivers ran a red light in a construction zone at 58 mph. Three people went to the hospital. One died. The judgment came back at $1.1M.

His problem wasn't the carrier. It was who the carrier was insured with. A surplus lines insurer domiciled in Bermuda, writing high-risk trucking policies that no admitted carrier would touch. When the claim hit, the insurer dragged their feet through discovery. Then they went into receivership. The state guaranty fund said: sorry, we don't cover non-admitted insurers. My friend had $1.1M in exposure and no one to collect from but himself.

He never checked the filing type on that FMCSA L&I record. He didn't know the difference between a BMC-91 and a BMC-91X. Most brokers don't.

What These Two Forms Actually Are

The FMCSA Licensing and Insurance database tracks every active insurance filing for every carrier operating in interstate commerce. When a carrier's insurer provides coverage, they file a form with FMCSA confirming that the carrier meets minimum financial responsibility requirements under 49 CFR § 387.7. That filing is either a BMC-91 or a BMC-91X.

The difference is who's filing it.

A BMC-91 is filed by an admitted insurer — a carrier that's licensed by state insurance departments to operate in that state, subject to state oversight, and backed by the state's insurance guaranty fund. Standard insurance companies like Great West, Protective Insurance, Canal Insurance, Old Republic. These are regulated entities playing by state rules.

A BMC-91X is filed by a non-admitted or surplus lines insurer. Non-admitted doesn't mean illegal — it means the insurer operates outside the normal state licensing framework, typically because they're writing coverage too unusual or risky for the admitted market to touch. They're still supposed to meet minimum surplus requirements and are often subject to some state oversight depending on jurisdiction, but they're NOT backed by the state guaranty fund.

That last part is the one that matters in a lawsuit.

State insurance guaranty funds exist to protect policyholders when an admitted insurer becomes insolvent. If Great West goes belly-up, the state guaranty fund covers claims up to the statutory limit — usually between $300K and $500K per claim depending on the state, though some states are higher. If your surplus lines insurer goes belly-up, the guaranty fund tells you to get in line with the other creditors. That line can take years and you'll likely collect pennies.

Why Carriers End Up on BMC-91X Filings

Here's what the form code is actually telling you about the carrier.

Admitted insurers underwrite to risk. They look at a carrier's safety record, inspection history, BASIC percentile scores, driver history, and equipment age. If a carrier looks like a bad risk by those metrics, the admitted market either declines to write the policy or prices it out of reach. The carrier then goes to the surplus lines market, where insurers write hard-to-place risk at premium prices.

So when you see a BMC-91X filing on a carrier, you're getting a signal: the admitted insurance market, which does this professionally and has skin in the game, looked at this carrier and said no. That's not a deal-killer on its own — plenty of legitimate carriers have niche operations that don't fit admitted underwriting boxes, or they're new authority without the history admitted insurers want to see. But it's information. It's the same signal you get when a carrier is running a high BASIC score: not proof of a problem, but a flag worth investigating.

New-authority carriers frequently file BMC-91X because admitted insurers often won't write a policy until a carrier has 12–18 months of operating history. The surplus market fills that gap. So a 6-month-old carrier with a BMC-91X isn't automatically suspicious. A 5-year carrier with a consistent safety record still on BMC-91X is worth a harder look.

Reading This in the FMCSA L&I Database

FMCSA's L&I system is publicly accessible at safer.fmcsa.dot.gov. Pull up any carrier's record and look at their active insurance filings. Each filing shows the insurer name, the NAIC code, the filing type (BMC-91 or BMC-91X), the effective date, and the coverage amount. DOTScreener pulls this directly as part of any screening — the form type is right there in the carrier's insurance history alongside whether it's currently active.

What you're doing when you look at this:

Step 1: Check the form type. BMC-91 = admitted. BMC-91X = surplus lines. Make a note.

Step 2: Look up the insurer. Take the NAIC code or insurer name and run it against AM Best. You want an AM Best financial strength rating of at least B+. Anything below that means the insurer is materially more likely to struggle paying claims. Some surplus lines insurers have excellent ratings — Lloyd's syndicates, for instance, are often A-rated non-admitted. Some have ratings that should make you nervous. A C-rated surplus insurer with a $750K BIPD filing is not actually giving your shipper $750K of real protection.

Step 3: Check the effective date and look for gaps. A filing that went active two weeks ago, on a carrier that's been around for three years, tells you the previous policy probably lapsed. Look at the filing history — L&I records prior filings including cancellations. A pattern of lapses is a different problem than a current surplus filing, but when you see both together it's a compounding risk.

Step 4: Match the coverage amount to the load. 49 CFR § 387.9 sets minimums: $750K BIPD for most dry van and general freight operations, $1M for certain hazmat categories, $5M for high-hazard materials. The minimum is the floor, not the right number. High-value loads, temperature-sensitive freight with spoilage exposure, or anything moving through construction corridors where severity is higher all warrant asking whether the carrier has excess coverage on top of their primary. A carrier running $750K primary with no umbrella on a high-value lane is operating right at regulatory minimum. Not illegal, but not protection.

The Part About Cargo Insurance

The BMC-91/91X distinction applies to liability coverage — BIPD, the bodily injury and property damage policy that pays third-party claims after a crash. Cargo insurance is different and is not required to be on file with FMCSA at all. That's a separate verification step.

What a lot of brokers miss: a carrier can have a valid, active BMC-91 liability filing and have no cargo insurance, or lapsed cargo insurance, or cargo insurance that explicitly excludes certain commodities or temperatures. The ACORD 25 is where cargo coverage shows up, and the FMCSA L&I database won't tell you anything about it. Those are two separate checks.

Under 49 CFR § 387.7, motor carriers operating in interstate commerce are required to maintain financial responsibility for bodily injury, property damage, and environmental restoration — not for cargo loss. Cargo coverage is governed by carrier tariffs, contract language, and what the shipper/broker negotiates. Federal minimum financial responsibility doesn't touch it.

So when you pull a COI and see $100K in cargo coverage, that's what the carrier declared. Whether that policy actually applies to your specific commodity, whether it excludes refrigerated loads or owner-operator drivers, whether the carrier has a high-deductible that makes the $100K coverage look better on paper than it performs in practice — none of that is in the FMCSA database. You need the actual policy or at least a certificate with the endorsements attached.

Post-Montgomery, the Filing Type Goes Into the Record

After Montgomery v. Caribe Transport II came down in May 2026, brokers can be sued in state court for negligent carrier selection. Plaintiffs' attorneys are going to be asking for your carrier file, your verification records, and your diligence on the carrier's financial responsibility — not just whether they had a certificate, but whether you made any judgment about the quality of that coverage.

"We got a COI" is not going to hold up under deposition if the COI was from a B-rated surplus lines insurer that was already on state regulators' watch list at the time you tendered. A reasonable-care standard isn't just "did you check a box." It's "did you think about what you were checking."

I'm not saying you need to underwrite every carrier's insurer. But knowing the difference between a filing that's backed by a state guaranty fund and one that isn't, and making a note of when you're accepting the extra risk, is part of a defensible vetting process.

How I Document This

When I screen a carrier on DOTScreener, the insurance section shows the active L&I filings including whether it's a BMC-91 or BMC-91X. Here's what goes into my carrier file note:

• Filing type: BMC-91 or BMC-91X
• Insurer name and NAIC code
• AM Best rating if I looked it up (I do this when I see a BMC-91X on a carrier I haven't used before, or when the surplus lines insurer name is unfamiliar)
• Coverage amount vs. what this load requires
• Effective date and any prior lapse in the filing history
• Cargo coverage as shown on the COI — separate line, separate box

If I'm onboarding a carrier I've never used and the filing is BMC-91X, I note that in the approval record. Not necessarily a rejection, but the file shows I was aware of it and made a considered decision. That's the difference between reasonable care and just running a checklist.

One more thing worth doing: if you're running a load with meaningful cargo value — a pharma load, a high-value electronics haul, specialty ag — ask the carrier if they have excess coverage available. Not all of them do, and not all shippers will pay the premium. But a carrier who can produce an umbrella or excess policy is a different risk profile than one running exactly $750K primary and nothing above it. The question itself goes into your notes either way.
