TL;DR: Federal filings are how FMCSA knows your insurance exists: your insurer files BMC certificates against your authority, your policy carries the MCS-90 endorsement, and lapses trigger revocation. These answers cover the forms, the deadlines, and the fixes when something goes wrong.
What are federal insurance filings in one minute?
FMCSA requires proof of financial responsibility before for-hire authority is granted or kept. Your insurer files electronic certificates, the BMC series, against your docket, and your liability policy carries the MCS-90 endorsement as proof at your place of business. The dollar minimums come from 49 CFR 387.9 and the filing mechanics from 49 CFR parts 365 and 387. The questions below are the ones carriers actually ask about how this works day to day.
Where do I check my own filing status?
FMCSA's public Licensing and Insurance website shows your active filings, insurer names, limits, effective dates, and any pending cancellations, searchable by USDOT or MC number. Checking it takes two minutes and settles most filing questions faster than any phone call. When in doubt, verify with FMCSA directly.
Real questions owner-operators, fleet managers, and new authorities ask
What is the MCS-90 endorsement in plain English?
It is a promise stapled to your liability policy: the insurer will pay final judgments against you from FMCSA-regulated operations up to the required limit, even if the policy would exclude the claim. The insurer can then collect that money back from you, which is why the endorsement is public protection, not extra coverage.
Is the MCS-90 filed with FMCSA?
No. The MCS-90 stays attached to your policy at your principal place of business as proof of financial responsibility under 49 CFR 387.7. What FMCSA receives is the separate BMC-91 or BMC-91X certificate, filed electronically by your insurer. Carriers routinely confuse the two documents.
What is the difference between BMC-91 and BMC-91X?
A BMC-91 certifies the full required liability limit from a single insurer. A BMC-91X certifies either full coverage or a layer stacked with other insurers to reach the limit. Layered programs file one BMC-91X per insurer. Both forms are filed electronically by insurers, never by carriers.
What liability limits do the filings have to show?
The tier for your commodity under 49 CFR 387.9: $750,000 for for-hire non-hazardous freight in vehicles of 10,001 pounds or more, $1,000,000 for oil and most listed hazmat, $5,000,000 for bulk high-hazard materials, all unchanged since January 1, 1985. Passenger carriers file $1,500,000 or $5,000,000 by seating capacity.
What is the 20-day rule for new authorities?
Under 49 CFR 365.109T, your insurance filing and Form BOC-3 process-agent designation must be on record within 20 days of the date FMCSA publishes your application in the FMCSA Register. Miss it and processing stalls; if no filing arrives within 90 days, the application is dismissed.
What is a BOC-3 and is it an insurance form?
The BOC-3 designates a process agent in each state to accept legal papers for your company. It is not insurance, but it shares the 20-day deadline with your insurance filing and authority will not issue without it. Process-agent services file it electronically for a small fee.
Do brokers file BMC-91 forms too?
No. Broker and freight forwarder authority requires $75,000 of security under 49 CFR 387.307: a BMC-84 surety bond or a BMC-85 trust fund, filed by the surety or trustee. A company holding both carrier and broker authority needs both kinds of filings, separately maintained.
What changed for broker trust funds in January 2026?
The rewritten 49 CFR 387.307 took effect January 16, 2026. BMC-85 trusts must now hold the full $75,000 in assets liquidatable within 7 calendar days, limited to cash, irrevocable letters of credit from federally insured institutions, and Treasury bonds. Illiquid or underfunded trusts no longer qualify.
Does FMCSA still require cargo insurance filings?
Only for household goods carriers and household goods freight forwarders, who file the BMC-34 certificate with BMC-32 endorsement. FMCSA eliminated cargo filings for general-freight carriers effective March 21, 2011. Cargo coverage itself remains a near-universal contract requirement from brokers and shippers.
What happens when my insurer cancels my policy?
Two notices: the insurer must give you 35 days written notice under 49 CFR 387.7(b), and it must file a BMC-35 cancellation notice giving FMCSA 30 days. If the filing dies with no replacement on record, FMCSA revokes your authority and your status flips to not authorized.
How do I switch insurers without risking my authority?
Bind the new policy effective on or before the old one ends, have the new insurer file its certificate, confirm it posts on FMCSA's Licensing and Insurance record, and only then let the old policy cancel. Done in that order, the public record never shows a gap.
How do I get reinstated after a revocation?
Bind replacement coverage and have the new filing posted, then submit FMCSA's reinstatement request, Form MCSA-5889, with the fee FMCSA lists at $80. Confirm your status shows authorized before dispatching, and expect some brokers to re-verify you before tendering again.
Who is allowed to file BMC forms?
Only insurers, sureties, and trust institutions holding FMCSA filer accounts, filing electronically under 49 CFR 387.323. Carriers and agents cannot upload filings. Your role is verification: check your docket on the public Licensing and Insurance site after binding, at renewal, and after any change.
Do intrastate-only carriers need federal filings?
Generally no MC authority or federal filing for non-hazardous intrastate work, but state requirements apply instead, and certain hazmat operations fall under federal minimums even intrastate under 49 CFR 387.9. Crossing a state line for hire changes the answer immediately.
Does my filing list my trucks?
No. BMC filings certify that required liability coverage exists at the required limit; they do not schedule vehicles. Adding or removing trucks changes your policy schedule and possibly your MCS-150 data and UCR bracket, but it does not require a new insurance filing.
What does it mean if my record shows a pending cancellation?
An insurer filed notice that your coverage will terminate on a stated date. Brokers monitoring your authority see it too. You have until that date to get a replacement filing posted; otherwise revocation follows. Treat a pending cancellation as a this-week problem, not a renewal-time problem.
