How does my trucking insurance get filed with FMCSA?

Who actually files my proof of insurance with FMCSA?

Not you. FMCSA says that once an entity files for operating authority, a financial responsibility provider must file the appropriate insurance forms on its behalf. A financial responsibility provider is an insurance or surety company, or another financial institution registered with FMCSA to make these filings.

FMCSA tells new registrants to contact that provider and ask for the filing immediately after they get their docket number. The agency also says it will not grant operating authority until the registrant has the minimum levels of financial responsibility on file.

In practice, that means your agent or insurer needs your USDOT and MC numbers, your legal name and address exactly as you registered them, and the authority type you filed for. FMCSA warns that any difference between the name and address in your pre-registration filings and your authority filing delays the grant.

What forms get filed, and what does each one mean?

For a motor carrier of property, FMCSA's filing chart lists these forms:

The limits behind the forms come from 49 CFR 387.9 and 387.303: $750,000 for a for-hire carrier of nonhazardous property in a vehicle of 10,001 pounds or more, $1,000,000 or $5,000,000 for certain hazardous materials. Those are floors, and no figure here is a price.

General freight carriers do not file cargo insurance. FMCSA's chart shows a cargo requirement of $0 for for-hire carriers of nonhazardous property, so a BMC-34 or BMC-83 is for household goods carriers. Your broker may still require cargo coverage by contract.

What is the difference between a BMC-91 and a BMC-91X?

This is where guides contradict each other, so here is the regulation's own wording. Under 49 CFR 387.311:

• A BMC-91 certificate of insurance represents the full minimum security limits required while it is in force.
• A BMC-91X certificate represents either the full security limits or the specific limits shown on the form. If limits are combined from more than one policy, the form must show whether the coverage is primary or excess, along with the underlying and maximum limits.
• A BMC-91MX shows the security limits on its face and follows the same primary or excess disclosure rules.

In plain terms, the BMC-91 is the simple case: one policy that meets the whole minimum. The BMC-91X is the form that can describe how limits are split across policies. Which one your insurer files depends on how your coverage is built. You do not choose the form; your insurer does. Ask your agent which one is going on file so that you can check it later.

One more caution from the same section: it contains a note barring combining limits to meet the $300,000 minimum for smaller vehicles until FMCSA completes a rulemaking. If your coverage is built from more than one policy, have your agent confirm that the filing is allowed for your vehicle class.

What is the MCS-90 endorsement?

The MCS-90 is an endorsement added to a motor carrier's insurance policy. Under 49 CFR 387.15, it must be in the form FMCSA prescribes, and it must state that coverage remains in effect continuously until terminated, as 387.7 requires. FMCSA's filing chart lists the MCS-90 for all for-hire and interstate motor carriers using insurance, and the MCS-82 for those using a surety bond.

Under 387.7(d), proof of the required financial responsibility must be kept at your principal place of business. An MCS-90 endorsement is one accepted form of that proof.

The endorsement is a federal filing requirement, and it does not mean your policy covers everything you might expect. Go through your policy's exclusions with your agent. See our primary auto liability page for the coverage itself.

How fast does the filing have to happen?

Once you file for authority and the filing is published in the FMCSA Register, FMCSA says the insurer's filing is expected within 20 days. If it is not on file, an FMCSA decision will be served saying the pending filing will be dismissed unless you comply within 60 days. Our post on how long authority takes shows how that fits into the full timeline.

After authority is granted, the filing has to stay current. FMCSA says entities must keep proof of insurance and designation of agents on file to avoid revocation proceedings, and the entity is responsible for monitoring that its filings stay up to date.

What happens if my policy is cancelled or lapses?

Federal rules call for continuous coverage. Under 49 CFR 387.7(b)(1), policies, surety bonds, and endorsements remain in effect continuously until terminated, and either the insurer or the carrier can end them by giving 35 days' written notice. The notice period starts when the notice is sent.

Two takeaways. First, a cancellation notice, from you or your insurer, starts a clock you do not want to ignore. Second, if you change insurers, the new filing has to be on record before the old one ends, or you risk a gap in the coverage FMCSA has on file, and a motor carrier cannot operate a motor vehicle without the minimum in effect (387.7(a)).

Note that you may see 30 days cited for filing cancellations. That figure comes from a separate section of the filing rules whose text carries a note that it is suspended. We use the 35 days stated in 387.7. Ask your insurer which notice period its policy and filing use.

What should I check once my insurance is filed?

1. Confirm the filing exists. Ask your agent for the confirmation or filing details, and ask when it was filed.
2. Check the names and numbers. The legal name, address, USDOT number, and MC number should match what you registered.
3. Check the authority type. The filing should match the type of authority you hold.
4. Calendar the renewal. When the policy renews, the filing has to continue without a gap.
5. Keep a copy of the certificate and the MCS-90 at your principal place of business.

If a broker asks for a certificate, that is a separate document from the FMCSA filing. Your agent issues it to the broker. The coverage needs tool shows which coverages usually come up, with no prices.
