The Name on the BMC-91 Matters More Than the Dollar Amount

A few years back I was reviewing a carrier's insurance before tendering a load. The ACORD 25 showed $1M in liability coverage. The FMCSA L&I page showed an active BMC-91 on file. Box checked.

Then I looked at the actual insurer name. Something like "Meridian Transport Casualty Solutions LLC." Never heard of them. I ran them through NAIC. Surplus-lines, licensed in two states, not admitted in most of the country. Low AM Best financial strength rating. A specialty program that served the distressed commercial auto market.

The carrier I was vetting had other problems too — a 78th percentile Unsafe Driving BASIC that I probably should have stopped at — but that's beside the point. The point is I almost approved them because I saw "$1,000,000" on an active filing and called it due diligence. The actual probability that policy paid a $1M claim was materially lower than the number implied.

Most brokers check the dollar amount. Almost none check whether the company behind it would actually write the check.

What BMC-91 and BMC-91X actually are

The BMC-91 is the insurance certificate that for-hire motor carriers file with FMCSA under 49 CFR § 387.7 to demonstrate they carry the required public liability insurance. The minimum amounts are set under § 387.9: $750,000 for general freight in property hauling. Most shippers and brokers require $1M as a baseline, and high-value or specialized lanes often push to $2M or more.

The BMC-91X is the alternative form used when a carrier meets the minimum through an excess or umbrella layer on top of a lower primary policy. If they have a $500K primary and a $500K excess, they file a BMC-91X rather than a BMC-91. What that means practically: there are now two insurers in the chain, and in a real claim, you're navigating primary-versus-excess coverage disputes before anyone writes a check.

Both forms are publicly available on FMCSA's L&I system for free. The filing shows the insurer name, policy number, effective and cancellation dates, and coverage type. What it does not show is anything about that insurer's financial health, claims-paying history, or whether they're actually admitted to do business in the state where your load is moving.

That gap is your problem to close, not FMCSA's.

Why insurer quality isn't a formality

Commercial auto insurance for trucking is a niche market dominated by a relatively small number of admitted carriers who actually underwrite the risk at scale. When a carrier gets rejected by those major players — whether for a bad loss ratio, a high BASIC score, or a safety history that's hard to defend — they end up in the surplus-lines market.

Surplus-lines insurance isn't inherently fraudulent. Some surplus-lines programs are well-capitalized and pay claims without drama. But the segment that serves distressed or high-risk trucking includes carriers that are thinly capitalized, fronting for offshore reinsurers, or simply designed to collect premiums and contest claims until plaintiffs give up or take settlement pennies on the dollar.

When a crash happens and the carrier has $1M on file but the insurer denies, delays, or enters receivership before settling — and this happens — the money the shipper or injury plaintiff thought existed isn't there. At that point the broker, especially post-Montgomery v. Caribe Transport II, LLC, is standing in the gap. You vetted the amount. You didn't vet the coverage.

I've heard from attorneys who've had exactly this situation: a trucking verdict well within the policy limit, insurer in financial distress, claim drags for years. The broker wasn't named in that suit, but they were in the next one.

How to check in five minutes

Start at FMCSA L&I, free and public. Pull the carrier's active insurance filings and look at the insurer of record. Then run that insurer through two lookups.

First: NAIC company search. This tells you the insurer's state of domicile, whether they're admitted in the relevant states, and their NAIC code. Admitted carriers operate within state insurance department oversight and benefit from state guaranty fund protection if they fail. Surplus-lines carriers don't get that backstop. Guaranty funds aren't unlimited and won't cover everything, but they're something. A surplus-lines carrier that goes under gives you nothing.

Second: AM Best financial strength rating. AM Best rates insurer financial health on a scale from A++ (Superior) down through B, C, and below. Most serious commercial auto carriers in the trucking space — your Great Wests, Old Republics, Canals, Protectives, Nationals — run A or A- or better. If the carrier's insurer comes back Not Rated, you're in unknown territory. Not Rated doesn't mean they're bad, but it means they haven't submitted to AM Best's scrutiny, which itself tells you something about how they operate.

If the insurer is rated B or below, that's a hard look. Not an automatic pass, but you need a reason beyond "the number is right."

A real example with fake numbers

Say I'm moving a $210,000 load of medical equipment from Nashville to Charlotte. The carrier is MC-1247893 / DOT-3567102 — 17 months active, 8 power units on MCS-150, no BASIC alerts, $1M in BIPD on file. On the surface, that's a passable vetting profile.

I pull the L&I. Insurer: let's call it "Coastal Casualty Holdings." Not a name I recognize. NAIC search shows they're a surplus-lines carrier domiciled in Delaware, not admitted in Tennessee or North Carolina. AM Best: no rating on file.

Now I have options. I can call the carrier and ask for the actual policy declarations page — not just the ACORD 25, which only shows the carrier name and dollar amount. The declarations page names the AM Best rating if there is one, names the surplus-lines broker or managing general agent in the chain, and tells me whether there's a fronting arrangement involved (i.e., a shell with a real carrier behind it). That chain matters.

In this scenario I'd either require a different carrier, require a higher coverage amount and see what they produce, or at minimum document what I found and what I decided to do about it. The worst outcome is a file that shows I never looked.

For a $210K load, a claims dispute with a B-rated surplus-lines carrier is not a small problem. The load value plus the liability exposure on a driver-injury claim could easily hit seven figures. I want an insurer who has actually paid seven-figure claims before.

The BMC-91X layer problem

When you see a BMC-91X on file — the excess form — ask how the layers are structured. If the primary is $100K from one insurer and the excess gets you to $750K or $1M from a second, you now have two potential coverage disputes before anyone settles a serious claim.

In a fatality case with a $4M demand, the primary insurer writes a $100K check and says the rest is someone else's problem. The excess insurer argues the primary should have settled before reaching their layer. Meanwhile, the plaintiff is waiting years. And you, as the broker, are named in the suit with your own carrier file in discovery.

Some carriers also use BMC-91X to aggregate lower-coverage policies that together meet the regulatory minimum. That structure is technically compliant under § 387.9 but means any significant claim triggers inter-insurer disputes about which layer covers what. You don't have to solve that problem, but you should know it exists before you put a $200K load on that truck.

Where the reg leaves off and your standard starts

The minimum requirements under § 387.9 set dollar floors. They don't say anything about insurer quality. FMCSA requires that the insurer be "qualified to do business" in the relevant jurisdiction, but there's no published approved list and no solvency review. The filing requirement exists to create a financial floor for public liability — not to certify that the floor will hold.

A broker who relies solely on "there's an active BMC-91 with a number that meets the minimum" is doing the regulatory minimum. Post-Montgomery, the legal standard for reasonable broker vetting is almost certainly higher than that. The Supreme Court's unanimous opinion opened state negligence claims against brokers precisely because state courts can evaluate whether the broker's conduct met a reasonable standard of care — and "I checked the number but not the insurer" is a thinner defense than it sounds.

How I document this

When the insurer on a BMC-91 is not one I immediately recognize — meaning not a major admitted commercial auto carrier — I add a note to the load file:

"BMC-91 verified on FMCSA L&I [date]. Insurer: [name]. AM Best: [rating or 'Not Rated']. [Admitted / Surplus-lines] in [operating state]. Proceeded based on [reason — e.g., declarations page reviewed, A-rated admitted in state, or risk-accepted with documentation]."

That takes 45 seconds. In a deposition three years later, it's the difference between "I checked the dollar amount on the filing" and "I checked the insurance, identified the specific insurer, verified their admitted status and AM Best rating, and made an informed decision about the adequacy of the coverage."

I've been in rooms where a broker couldn't answer the second version of that question. The plaintiff's attorney can. The difference shows.

The BMC-91 is a starting point, not a finish line. It tells you a carrier filed evidence of insurance. It doesn't tell you that insurance is any good. Take the extra five minutes.
