If you operate a commercial motor vehicle in interstate commerce, the Federal Motor Carrier Safety Administration (FMCSA) requires you to carry minimum levels of liability insurance before you can legally haul freight. No insurance filing, no operating authority — and the penalties for running without proper coverage can shut down your operation entirely.
This guide covers every FMCSA insurance requirement you need to know: the federal minimums by cargo type, how the filing process works, what happens if coverage lapses, and how motor carriers can stay compliant without overpaying for coverage they don’t need.
What Is the FMCSA and Why Does It Set Insurance Requirements?
The FMCSA is the federal agency within the U.S. Department of Transportation responsible for regulating commercial motor vehicle safety. Under 49 CFR Part 387, the FMCSA mandates that all motor carriers transporting property or passengers in interstate commerce maintain a minimum level of financial responsibility — what the industry simply calls insurance requirements.
The purpose is straightforward: if a commercial truck causes an accident, there must be a guaranteed source of funds to compensate injured parties. The federal minimums set the floor; your state may have additional requirements on top of them.
FMCSA Minimum Insurance Requirements by Carrier Type
FMCSA insurance minimums are not one-size-fits-all. The required coverage amount depends on what you haul and how heavy your vehicle is. Here are the federal minimums as set under 49 CFR 387.9:
| Cargo / Operation Type | Minimum Liability Coverage |
|---|---|
| Non-hazardous freight, vehicles >10,001 lbs GVWR | $750,000 |
| Hazardous materials (oil, listed in 49 CFR 172.101) | $1,000,000 |
| Hazardous materials (explosives, radioactive materials, certain poisons) | $5,000,000 |
| For-hire passenger carriers (>15 passengers) | $5,000,000 |
| For-hire passenger carriers (6–15 passengers) | $1,500,000 |
The $750,000 minimum applies to the vast majority of dry van, flatbed, and refrigerated carriers hauling standard freight. If you’re hauling petroleum products or other hazardous materials, expect at least $1,000,000 in required coverage — and significantly higher premiums to match.
How FMCSA Insurance Filings Work
It’s not enough to simply purchase a policy. The FMCSA requires that your insurance provider file proof of coverage directly with the agency. Your insurer submits one of two forms:
- Form BMC-91 or BMC-91X — standard motor carrier liability certificate. This is the most common filing for property carriers.
- Form BMC-34 — used by motor carriers that choose to self-insure (requires FMCSA approval and proof of financial fitness).
Until the filing is received and active in the FMCSA’s SAFER system, your operating authority remains inactive. The FMCSA Registration portal shows the real-time status of your authority and insurance filings. Check it regularly — a lapsed filing is one of the most common reasons motor carriers lose authority unexpectedly.
What Happens If Your FMCSA Insurance Lapses
Insurance lapses are a serious operational risk. When your insurer cancels your policy or the filing falls out of compliance, they are required to notify the FMCSA. The agency will then issue a notice of revocation of your operating authority — typically with 30 days’ notice, but in some cases immediately.
Consequences of operating with revoked authority include:
- Civil penalties of up to $16,000 per day per violation
- Out-of-service orders at roadside inspections
- Difficulty reinstating authority (a new application may be required)
- Damaged relationships with brokers who verify carrier authority before tendering loads
The single best protection is setting up automatic renewal notifications with your insurer and confirming the BMC-91 filing is active after every policy renewal.
Cargo Insurance vs. Liability Insurance: What’s the Difference?
The FMCSA minimum liability coverage protects third parties — people and property outside your truck — if you cause an accident. It does not protect the freight you’re hauling. That’s a critical distinction.
Cargo insurance (also called motor truck cargo insurance) covers the value of the freight itself in the event of theft, damage, or loss. Many shippers and brokers require $100,000 in cargo coverage as a contract condition, even though FMCSA doesn’t mandate it federally.
A complete insurance package for most carriers typically includes:
- Primary auto liability — the federally required coverage ($750,000+)
- Motor truck cargo — freight protection ($100,000–$250,000 is standard)
- Physical damage — covers your tractor and trailer
- General liability — slip-and-fall and non-driving incidents at shipper/receiver facilities
- Bobtail/non-trucking liability — covers the tractor when operating without a loaded trailer
Special FMCSA Insurance Requirements
Hazmat Insurance Requirements
Carriers hauling hazardous materials face higher minimums and additional compliance obligations. Beyond the $1,000,000–$5,000,000 liability floor, hazmat carriers must also register with the Pipeline and Hazardous Materials Safety Administration (PHMSA) and maintain a current Hazardous Materials Safety Permit for certain commodities. See our detailed breakdown of FMCSA hazmat insurance requirements for specifics by commodity class.
Freight Broker Insurance Requirements
Freight brokers — companies that arrange transportation but don’t haul freight themselves — have a separate FMCSA insurance obligation. Brokers must maintain a $75,000 surety bond (BMC-84) or trust fund (BMC-85) as their form of financial responsibility. Motor carrier liability insurance does not satisfy this requirement. For a full breakdown, see our guide on insurance requirements for freight brokers.
New Motor Carrier Insurance Requirements
New entrants applying for operating authority must have their BMC-91 filed and confirmed before the FMCSA will grant active authority. New carriers also complete an 18-month new entrant safety audit program, during which insurance compliance is closely monitored. One lapse during this period can result in permanent revocation of authority.
How Much Does FMCSA-Compliant Insurance Cost?
Insurance costs vary significantly based on your operation. For an owner-operator running a single dry van truck with a clean record, primary auto liability meeting the $750,000 minimum typically costs $8,000–$14,000 per year. Add cargo coverage, physical damage, and general liability and a comprehensive package often runs $12,000–$20,000 annually.
Factors that affect your premium include:
- Years in business (new authorities pay significantly more — often 2x–3x)
- Driver MVR records and CSA scores
- Radius of operation and lanes traveled
- Cargo type (hazmat, high-value electronics, and auto hauling command higher rates)
- Loss history and prior claims
Comparing quotes from multiple trucking-specialized insurers — rather than general commercial insurers — is the most reliable way to reduce costs while maintaining full compliance.
Staying FMCSA Insurance Compliant: A Checklist
- Confirm your operating authority type (property carrier, passenger carrier, broker) to identify which form of financial responsibility applies
- Verify your BMC-91/91X filing is active in FMCSA’s SAFER system before moving any loads
- Set renewal reminders 60 days before policy expiration — don’t wait for your insurer
- Notify your insurer immediately of any fleet additions or commodity changes that could affect your coverage requirement
- Audit your cargo insurance limits against broker and shipper contract requirements annually
- Keep a copy of your certificate of insurance accessible in every cab
Frequently Asked Questions
What is the minimum insurance required by FMCSA?
The FMCSA minimum for most property-carrying motor carriers is $750,000 in primary auto liability coverage. Carriers transporting hazardous materials must carry $1,000,000 to $5,000,000 depending on the commodity. These minimums are established under 49 CFR Part 387.
Does FMCSA require cargo insurance?
No — FMCSA does not federally mandate cargo insurance for property carriers. However, most brokers and shippers require $100,000 in cargo coverage as a contract condition. Without it, you will be unable to access the majority of freight available through load boards and broker relationships.
How do I check if my FMCSA insurance is active?
Visit the FMCSA SAFER System and search by your USDOT number or MC number. Your active insurance filings will be listed under “Insurance/Financial Responsibility.” If a filing shows as “canceled” or is absent, contact your insurer immediately.
What happens if my FMCSA insurance lapses?
If your insurance filing lapses, the FMCSA will initiate revocation of your operating authority. Operating with revoked authority exposes you to civil penalties of up to $16,000 per day. Reinstatement requires a new filing plus, in some cases, a new application for authority.
Is $750,000 enough insurance for a trucking company?
$750,000 meets the federal minimum, but many industry experts recommend $1,000,000 in primary liability for additional protection. A single serious accident — particularly one involving multiple vehicles or fatalities — can generate claims that exceed $750,000. Consult a trucking insurance specialist to determine the right level for your operation.
Do freight brokers need the same insurance as motor carriers?
No. Freight brokers are not required to carry motor carrier liability insurance. Instead, they must maintain a $75,000 surety bond (BMC-84) or trust fund (BMC-85). Some shippers also require brokers to carry contingent cargo coverage, though this is not a federal requirement.
