If you’re operating as a for-hire motor carrier across state lines, insurance coverage isn’t just a smart decision, it is a federal requirement. That’s where the BMC-91X filing comes in.
Many truckers hear about “getting their filings done” without fully understanding what those filings are, why they’re important, or how they impact the launch (and compliance) of their business.
What is a BMC-91X Filing?
A BMC-91X is a federal filing submitted to the Federal Motor Carrier Safety Administration (FMCSA) that proves you have the required insurance coverage to operate as a for-hire carrier in interstate commerce. It’s not an insurance policy, it’s a certificate of proof that your insurance meets federal standards. Without this on file, the FMCSA won’t activate your motor carrier (MC) number.
What Does It Cover?
The BMC-91X filings verify that you carry public liability insurance, which includes:
- Bodily Injury
- Property Damage
- Environmental Restoration
Coverage limits are determined by the type of freight you haul. Most for-hire carriers need a minimum of $750,000, though carries hauling hazardous materials may be required to carry up to $5 million.
My Policy Limit Is $1M But My Filings Show $750K. Why?
The FMCSA requires a minimum of $750,000 in liability coverage for more for-hire carriers, so your BMC-91X reflects that minimum to meet federal regulations. However, many brokers and shippers push carriers to carry $1 million in coverage for added protection and to qualify for more freight opportunities.
In short: Your policy may cover up to $1 million, but federal filings only need to show the regulatory minimum. It keeps you compliant while ensuring you’re protected and marketable in today’s freight environment.
Who Needs a BMC-91X Filing?
If you’re operating as a for-hire carrier across state lines and are required to have an active MC number, you’ll need a BMC-91X filed before your authority can go active. This applies to:
- New ventures applying for motor carrier authority
- Carriers making changes to their current insurance policy or switching providers
- Any business updating their DOT or MC records
How Does It Work?
After purchasing an insurance policy that meets federal requirements, your insurance provider files the BMC-91X electronically with the FMCSA. Once it’s accepted and processed, your MC number can become active. This filing must stay up to date. If your policy cancels, the FMCSA will be notified and your authority could be revoked.
The BMC-91X filing is a critical step in launching and maintaining your trucking authority. It proves that you carry the insurance required to protect the public and stay compliant with FMCSA regulations. Whether you’re just starting out or updating your coverage, keeping this filing current ensures your business stays on the road.
