If you operate a commercial motor vehicle in interstate commerce, the Federal Motor Carrier Safety Administration (FMCSA) requires you to maintain specific minimum insurance levels β and to file proof of that coverage with the federal government. Getting this wrong doesn’t just mean a fine. It means your operating authority gets suspended, your trucks get placed out of service, and every load you’ve moved without coverage becomes a potential personal liability. This guide explains FMCSA insurance requirements in plain language so you know exactly what’s required, how to file it, and what happens if you fall out of compliance.
Who Is Required to Have FMCSA Insurance?
FMCSA insurance requirements apply to:
- For-hire motor carriers transporting property or passengers in interstate commerce
- Private carriers transporting hazardous materials in interstate commerce
- Freight brokers and freight forwarders (different requirements, typically surety bond or trust fund)
- Leasing companies that regularly engage in the leasing of motor vehicles
If you’re operating entirely within one state (intrastate), you’re subject to that state’s requirements, not the FMCSA’s federal minimums β though many states have adopted the same or similar minimums.
FMCSA Minimum Insurance Limits by Freight Type
The FMCSA sets minimum liability insurance levels based on what you’re hauling and your vehicle type. These are the most current federally mandated minimums:
| Commodity / Operation Type | Minimum Liability Required | CFR Reference |
|---|---|---|
| For-hire carriers of non-hazardous property, vehicles >10,000 lbs GVWR | $750,000 | 49 CFR Part 387.9 |
| For-hire carriers of non-hazardous property, vehicles β€10,000 lbs GVWR | $300,000 | 49 CFR Part 387.9 |
| For-hire carriers of non-bulk oil (in interstate or foreign commerce) | $1,000,000 | 49 CFR Part 387.9 |
| For-hire carriers of non-bulk hazardous materials (listed in Β§172.101) | $1,000,000 | 49 CFR Part 387.9 |
| For-hire or private carriers of bulk hazardous materials (explosive/poison gas) | $5,000,000 | 49 CFR Part 387.9 |
| For-hire or private carriers of bulk hazardous materials (other) | $1,000,000 | 49 CFR Part 387.9 |
| For-hire passenger carriers (8+ passengers, for compensation) | $5,000,000 | 49 CFR Part 387.33 |
| For-hire passenger carriers (fewer than 16 passengers, not for hire) | $1,500,000 | 49 CFR Part 387.33 |
Key point: The $750,000 minimum for general freight has not been updated since it was established in the 1980s. In today’s litigation environment β with nuclear verdicts regularly exceeding $10 million β most experienced carriers and brokers strongly recommend purchasing $1,000,000 in primary liability regardless of what you haul. The premium difference between $750K and $1M is typically minimal.
The MCS-90 Endorsement: What It Is and Why It Matters
The MCS-90 is a mandatory endorsement that must be attached to every primary liability policy held by a for-hire interstate motor carrier. It’s not a separate insurance policy β it’s an endorsement that modifies your existing policy in a very important way.
What the MCS-90 does: It creates an absolute obligation for your insurer to pay a judgment against you for bodily injury or property damage β even in situations where your underlying policy might not normally cover the loss. The endorsement ensures that injured members of the public are not left without recourse just because of a policy exclusion or administrative issue.
The insurer’s right of recovery: When an insurer pays a claim under the MCS-90 that it wouldn’t have paid under the base policy, it has the right to recover that payment from the motor carrier. This is why compliance with your policy conditions isn’t just a formality β violations that trigger an MCS-90 payout can result in the insurer pursuing you personally for reimbursement.
Your insurer files the MCS-90 endorsement with the FMCSA on your behalf when you purchase a qualifying policy. You should receive a copy for your records. The endorsement must remain on file with the FMCSA throughout your operating authority’s active period.
Form BMC-91 and BMC-91X: The Federal Filing Forms
Form BMC-91: Certificate of Insurance
Form BMC-91 is the certificate used by insurance companies to certify to the FMCSA that a motor carrier meets the minimum financial responsibility requirements for property carriage. When your insurer completes and files a BMC-91, they are formally notifying the FMCSA that your policy is in force and meets federal minimums.
The BMC-91 must be filed by an authorized insurance company β not by the carrier itself β directly with the FMCSA. This filing triggers the activation of your operating authority (along with the MCS-150 registration and payment of the USDOT number fees).
Form BMC-91X: Surety Bond
Form BMC-91X is the surety bond equivalent. If a carrier uses a surety bond to satisfy financial responsibility requirements rather than an insurance policy, the surety company files the BMC-91X. This is less common for motor carriers but is the standard for freight brokers (who must file a BMC-84 or BMC-85 trust fund).
What Happens When Your Policy Cancels
When your insurance policy is cancelled or not renewed, your insurer is required to notify the FMCSA by filing a BMC-35 notice of cancellation. The FMCSA then automatically suspends your operating authority if a replacement filing isn’t received before the cancellation date. This is why policy lapses are so dangerous β even a single day without an active filing can trigger a suspension that takes weeks to resolve.
How to File Insurance with the FMCSA
As a motor carrier, you don’t file directly with the FMCSA yourself. Here’s how the process works:
- Purchase a qualifying policy: Buy a commercial trucking liability policy from an insurer authorized to write motor carrier coverage and file FMCSA forms.
- Your insurer files the BMC-91 and MCS-90: Confirm with your agent or broker that the filing is being submitted. Ask for the filing confirmation number.
- Verify the filing in SAFER: Go to safer.fmcsa.dot.gov and look up your USDOT number. Under “Insurance,” you should see your active policy listed as “Authorized” with the correct effective date.
- Maintain continuous coverage: Never let a policy lapse without a replacement filing in place. Coordinate policy renewals 2β4 weeks in advance.
- Update for material changes: If you change carriers, add HAZMAT operations, or significantly change your operation, notify your insurer and confirm new filings if required.
What Happens If You’re Caught Operating Without FMCSA Insurance?
Operating a commercial motor vehicle without the required FMCSA insurance filings is not just a citation β it has serious cascading consequences:
Immediate Authority Suspension
If your BMC-91 lapses, the FMCSA will suspend your operating authority effective the cancellation date. You cannot legally haul freight for compensation until the suspension is lifted and new filings are received.
Out-of-Service Orders
If you’re caught operating without proper insurance during a roadside inspection or weigh station check, your vehicle can be placed out of service immediately. You won’t be moving until the issue is resolved.
Civil Penalties
Operating without the required financial responsibility can result in civil penalties up to $16,000 per violation under 49 U.S.C. Β§ 14901. Each day of non-compliance may be treated as a separate violation.
Personal Liability Exposure
If you’re in an accident while operating without required coverage, you may be personally liable for all damages β medical bills, property damage, lost wages, pain and suffering, and legal fees β with no insurer to defend you or pay on your behalf. For a serious accident, this can mean millions of dollars in personal exposure.
State vs. Federal Requirements
Federal FMCSA requirements apply to interstate commerce (crossing state lines). But many states have their own requirements for intrastate operations that are different from federal minimums. Important distinctions:
- Some states require higher minimums: California, for example, requires $1,000,000 for certain operations. Always verify your state’s requirements if you operate intrastate.
- State-specific endorsements: Some states require additional filings or endorsements beyond the federal MCS-90.
- Both can apply simultaneously: An interstate carrier based in a state with higher intrastate minimums must comply with both the federal requirements AND the state requirements.
When in doubt, work with a broker who knows your state’s specific requirements. Compliance with federal minimums alone may not be enough to legally operate in your home state.
Insurance Requirements for Freight Brokers
Freight brokers don’t haul freight, so they don’t need primary liability or cargo insurance. However, the FMCSA requires brokers to maintain a surety bond or trust fund:
- BMC-84 Surety Bond: Minimum $75,000. Filed by a surety company to protect shippers and carriers against broker defaults.
- BMC-85 Trust Fund: Minimum $75,000 held in a qualifying financial institution.
Many brokers also carry contingent cargo insurance and errors & omissions (E&O) coverage, though these are not federally mandated.
How to Verify Your FMCSA Insurance Status
You can verify your insurance filings are active at any time by going to the FMCSA SAFER system:
- Go to safer.fmcsa.dot.gov
- Click “Company Safety Profile” or use the search by USDOT number or MC number
- Under the “Insurance” section, you’ll see all active filings, coverage types, effective dates, and the insuring company
- Status should show “Authorized” β not “Revoked,” “Suspended,” or blank
Check this regularly, especially when you renew your policy. It can take a few business days for new filings to appear in SAFER. If your renewal date passes and the new filing isn’t reflected within 5 business days, call your broker immediately.
Frequently Asked Questions
Do I need FMCSA insurance before my MC number is approved?
You need to have insurance filed before your authority becomes active. The FMCSA grants provisional authority when you apply, but it doesn’t activate until the 21-day protest period passes AND your insurer has filed the required BMC-91 and MCS-90. Don’t start hauling freight for hire until you’ve confirmed your authority status shows “Active” in SAFER.
What if I’m just running intrastate?
If you operate entirely within one state, you’re subject to that state’s requirements, not FMCSA federal minimums. However, if you ever cross state lines β even occasionally β you need to comply with FMCSA requirements for that trip. Many carriers opt to meet federal requirements regardless so they can take interstate loads without restriction.
My insurer says they filed. How do I confirm it?
Check the FMCSA SAFER system at safer.fmcsa.dot.gov. Your active policy should appear in the Insurance section within 5β7 business days of filing. If it doesn’t appear, contact your broker β not your insurance company directly β to track down the filing status.
Can I use an umbrella policy to meet FMCSA minimums?
No. The MCS-90 endorsement must be attached to a primary liability policy that directly covers trucking operations. An umbrella or excess policy sits above the primary policy and cannot substitute for it. You need a qualifying primary policy with the MCS-90 attached.
How often are FMCSA minimum limits updated?
Rarely. The current $750,000 minimum for general freight has been in place since 1985 and has not kept pace with inflation or verdict trends. The FMCSA has discussed updating minimums but no change has been enacted as of 2026. Industry groups and safety advocates continue to push for increases. For now, $750K remains the legal minimum β but $1M is strongly recommended.
