An FMCSA filing is a formal insurance document submitted to the Federal Motor Carrier Safety Administration (FMCSA) by your insurance company to prove that your trucking operation meets federal minimum insurance requirements. FMCSA filings are required to obtain and maintain operating authority (an MC number), and they must remain active at all times for your authority to stay valid. The most common FMCSA filings are the BMC-91 (primary liability), BMC-34 (cargo), and Form E (for intrastate filings).
Why FMCSA Filings Are Required
The FMCSA requires insurance filings because it needs documented proof that carriers operating in interstate commerce have the minimum coverage required by federal law. Without active filings, the FMCSA will not grant operating authority, and if filings lapse after authority is granted, the FMCSA will revoke your MC number. Your authority going inactive means you cannot legally transport federally regulated commodities across state lines.
Filings are also the mechanism by which the public β including accident victims and shippers β can verify that a carrier is properly insured. The FMCSA’s Licensing and Insurance (L&I) database is publicly searchable and shows the status of all carrier filings in real time.
The Three Main FMCSA Insurance Filings
BMC-91 (Primary Liability Filing)
The BMC-91 is the primary FMCSA filing for trucking liability insurance. It certifies that your policy meets the minimum public liability requirements under 49 CFR Part 387. The BMC-91 is filed by your insurer electronically with the FMCSA and tied to your DOT and MC numbers. Required minimum limits:
- $750,000 for general freight carriers
- $1,000,000 for household goods and oil transport
- $5,000,000 for certain hazardous materials
BMC-34 (Cargo Liability Filing)
The BMC-34 filing certifies that you carry the minimum required cargo insurance. It is required for household goods movers ($5,000 per vehicle minimum) and freight forwarders. Most general freight carriers are not required to file a BMC-34, but many do so voluntarily to demonstrate cargo coverage to shippers. The filing is submitted by your cargo insurer to the FMCSA.
Form E (State Intrastate Filing)
Form E is the state-level equivalent of the BMC-91 for carriers operating under intrastate authority. It is submitted to your state’s Department of Transportation or Public Utilities Commission rather than the FMCSA. Requirements vary by state, but most require minimum liability limits comparable to federal standards. If you operate in multiple states under intrastate authority, you may need a Form E filed in each state.
How FMCSA Filings Work
When you bind a new trucking liability policy, your insurer is responsible for submitting the appropriate FMCSA filings electronically. This typically happens within 1β3 business days of policy binding. The FMCSA’s L&I database is updated continuously, and brokers and shippers often verify filing status before tendering loads.
When a policy is cancelled or lapses, the insurer submits an MCS-25 or MCS-26 cancellation notice, giving the FMCSA 30 days’ notice before the filing is terminated. If you do not replace your coverage within that 30-day window, your operating authority will be revoked.
At Full Coverage LLC, we handle all FMCSA filing submissions as part of our standard service. We also monitor filing status and alert you before any lapse can affect your authority.
Cost Considerations
FMCSA filings themselves do not have a separate cost β they are a service performed by your insurer as part of your policy. However, the underlying insurance policy that enables the filing varies in cost:
- New authority (BMC-91 filing, $750K general freight): $10,000β$18,000/year
- Established carrier (2+ years, clean record): $7,000β$13,000/year
- Hazmat carriers requiring $5M limits: $20,000β$40,000+/year
“The number one mistake new carriers make is binding a policy and assuming the FMCSA filing happens automatically and instantly. It does happen automatically with most carriers β but ‘instantly’ is relative. I’ve seen filings take 24β72 hours to appear in the FMCSA database, and a broker who checks during that window will see no active filing. At Full Coverage LLC, we confirm filing status before our clients start dispatching.”

Frequently Asked Questions About FMCSA Filings
How long does it take to get an FMCSA filing activated?
Most FMCSA filings are submitted electronically and appear in the FMCSA Licensing and Insurance database within 24β72 hours of policy binding. Some insurers file within hours. Before dispatching any loads, verify your filing status is “Active” in the FMCSA L&I system at safer.fmcsa.dot.gov.
What happens if my FMCSA filing lapses?
When an insurer cancels an FMCSA filing, they submit a cancellation notice giving 30 days’ advance notice to the FMCSA. During that 30-day window, you must replace your coverage and have a new filing activated or your operating authority will be revoked. Operating after authority revocation is a serious federal violation subject to fines and out-of-service orders.
Do I need both a BMC-91 and BMC-34?
Most general freight carriers only need the BMC-91 (liability filing). The BMC-34 (cargo filing) is specifically required for household goods movers and freight forwarders under federal regulations. General freight carriers may voluntarily file a BMC-34 to demonstrate cargo coverage to shippers but are not legally required to do so.
Where can I check my current FMCSA filing status?
You can check your FMCSA filing status at safer.fmcsa.dot.gov by searching your DOT number or company name. The Licensing and Insurance (L&I) section will show all active and historical insurance filings, their effective dates, and whether they are currently active or inactive.
