BIPD primary insurance: what it means on your FMCSA record

What BIPD primary insurance means

BIPD stands for bodily injury and property damage liability: the coverage that pays other people when your truck hurts someone or damages their property. FMCSA guidance on 49 CFR 387.15 says a carrier may meet its federal minimum by buying insurance in layers, each with its own policy and endorsement. The first layer is called primary insurance and each additional layer is called excess insurance.

So “primary” describes position, not a separate product. If one insurer writes your entire $1,000,000 auto liability limit, that policy is your primary BIPD. Primary pays first, up to its limit; an excess layer responds only after the layers below it are used up.

Each layer carries its own MCS-90 endorsement. In FMCSA’s example, the primary insurer’s endorsement caps its liability at $1,000,000 per accident, while each excess insurer states a limit that applies “in excess of the underlying limit” beneath it.

Primary vs excess BIPD: how the layers stack

FMCSA’s own example is a carrier hauling Division 1.1 explosives, which must carry $5,000,000. It buys three policies from three insurers.

When layers are filed, FMCSA’s filing instructions say a 91X Primary certificate records the maximum coverage, while a 91X Excess certificate records both the maximum and the underlying coverage. That is how your record shows where each excess layer starts.

Why your record says BMC-91X and BIPD/Primary

Under 49 CFR 387.313, Form BMC-91 is filed for the full required limit, while Form BMC-91X can represent full coverage or any level of aggregation. When more than one insurer stacks layers to reach the limit, each insurer files its own BMC-91X. FMCSA’s filing system lists certificate types including BIPD-91X Primary, BIPD-91X Excess and BIPD-91.

In practice, many single-insurer policies are filed on the 91X as primary. Public copies of FMCSA insurance history show rows with form 91X, type BIPD/Primary, the insurer, policy number, coverage, effective date and whether the filing was later cancelled or replaced. A BIPD/Primary row with no excess row means one insurer carries your whole filed limit.

FMCSA’s carrier search also shows the BIPD amount required for your operation and the amount on file. A “No” status means the carrier lacks active authority or is out of compliance and may face revocation, according to FMCSA.

How much primary BIPD you need

The federal floor depends on what you haul and how heavy your vehicles are. One primary policy or primary plus excess layers can meet it.

Most freight contracts ask for more. Marquee Insurance Group, a trucking agency, notes that the $1,000,000 limit common in trucking comes from brokers, shippers and load boards rather than FMCSA. If a contract asks for a higher limit, check whether it accepts an excess or umbrella policy on top of your primary.

Why the filing may show $750,000 on a $1,000,000 policy

Marquee Insurance Group explains that insurers commonly file at the federal minimum because the BMC-91X and MCS-90 are a promise to the public: the insurer can be made to pay an injured person up to the filed amount even where the policy would not, then seek reimbursement from you. Your certificate of insurance still shows the full policy limit, which is what brokers check.

The agency warns against raising the “insurance required” amount on your FMCSA record to $1,000,000 to match your policy. The filing will not follow, and FMCSA gives you 30 days to fix the shortfall before revoking authority. FMCSA’s filing help lists $750,000, $1,000,000, $1,500,000 and $5,000,000 as common filed amounts.

Cancellations, replacements and Motus

Under 49 CFR 387.313(d), a certificate cannot be cancelled until 30 days after the insurer, carrier or other party files a BMC-35 cancellation notice with FMCSA. Under 387.313(e), when a new certificate replaces an old one, the old insurer’s liability ends on the replacement’s effective date. That is why insurance histories show some filings as “Replaced” and others as “Cancelled.”

In a layered program, each layer is a separate filing with its own cancellation clock. If your primary layer cancels and nothing replaces it, the excess filing still sits above an underlying limit you no longer have, so get the replacement primary filed before the cancellation date.

FMCSA moved registration into its new Motus system in May 2026 and says existing Licensing and Insurance records remain viewable. Marquee Insurance Group notes that insurers now submit BMC-91X filings through Motus, so new filings can take longer to appear.

How to keep your primary BIPD filing clean

Most filing problems come from timing and mismatched records, not from the coverage itself.

Pricing for higher primary limits and excess layers varies by insurer and operation. A broker such as Florin can compare primary and excess options from several insurers.

• Make sure the cargo and operation on your FMCSA record match what you actually haul, so the required amount matches what your insurer files.
• Ask your agent which form, layer and amount will be filed, then check your USDOT record after it posts.
• Send brokers your certificate of insurance for the full policy limit instead of changing the required amount on your FMCSA record.
• When you switch insurers, have the new primary filing take effect on or before the old policy’s cancellation date.
• Before adding hazmat, line up the higher policy limit and filing first, then update your FMCSA record.
• If you add an excess layer for a contract, confirm whether the customer needs it filed with FMCSA or only shown on the certificate.
