The Federal Motor Carrier Safety Administration sets federal floor on how much liability insurance a trucking company must carry before it can haul freight in interstate commerce. Getting that number wrong — either by carrying too little or by misunderstanding what qualifies — puts your operating authority at risk.
Here is a precise breakdown of FMCSA minimum insurance requirements under 49 CFR Part 387, what factors determine your minimum, and what to do to confirm your coverage meets the standard.
The FMCSA Minimums at a Glance
Under 49 CFR § 387.9, the minimum levels of financial responsibility vary based on the type of operation and the commodity hauled:
| Operation Type | Commodity | Minimum Coverage |
|---|---|---|
| For-hire motor carrier (property) | Non-hazardous freight, vehicles >10,001 lbs GVWR | $750,000 |
| For-hire motor carrier (property) | Hazardous materials — oil (49 CFR 172.101) | $1,000,000 |
| For-hire motor carrier (property) | Hazardous materials — explosives, radioactive, certain poisons | $5,000,000 |
| For-hire motor carrier (passengers) | Vehicles transporting >15 passengers | $5,000,000 |
| For-hire motor carrier (passengers) | Vehicles transporting 6–15 passengers | $1,500,000 |
| Private carrier (property) | Hazardous materials requiring placarding | $1,000,000 or $5,000,000 |
The $750,000 minimum is the most commonly cited figure because it applies to the largest segment of the trucking industry: for-hire carriers moving non-hazardous goods in vehicles above the 10,001 lb GVWR threshold. If your trucks weigh less than 10,001 lbs, different thresholds apply and you may not require an FMCSA operating authority at all.
What Counts Toward the FMCSA Minimum?
Only primary automobile liability insurance counts toward satisfying the FMCSA minimum. Specifically, your policy must cover bodily injury and property damage liability arising from the operation of commercial motor vehicles in interstate commerce.
The following do not count toward your FMCSA minimum:
- Cargo insurance — protects the freight, not third-party bodily injury
- Physical damage coverage — covers your own equipment
- General liability — covers non-vehicle incidents
- Umbrella/excess liability — generally does not satisfy the primary liability requirement on its own
- Occupational accident coverage — covers drivers, not third parties
Your insurer must file Form BMC-91 or BMC-91X directly with the FMCSA to certify that the policy satisfies the minimum financial responsibility requirement. A policy that meets the dollar threshold but has not been properly filed with the FMCSA does not satisfy the regulation.
Endorsement MCS-90: What It Is and Why It Matters
Policies issued to motor carriers operating in interstate commerce must include the MCS-90 endorsement. This endorsement obligates your insurer to pay claims up to the required minimum even if the underlying policy has exclusions that would otherwise deny the claim — for example, a driver operating outside an approved route.
The MCS-90 is not additional coverage. It is a regulatory backstop that ensures injured third parties can recover compensation regardless of policy exclusions. If your insurer pays out under MCS-90 due to an excluded claim, they can seek reimbursement from you directly. This is an important reason to maintain accurate driver logs, route compliance, and cargo manifests.
How the FMCSA Verifies Your Coverage
The FMCSA does not verify coverage by reviewing your certificate of insurance. Instead, it relies entirely on insurer filings. Your insurance company electronically submits BMC-91/91X forms directly to the FMCSA, which updates the SAFER database in near real time.
You can check your current filing status at any time via the FMCSA SAFER System. Search by your USDOT number and review the “Insurance/Financial Responsibility” section. The filing should show:
- Type: BMC-91 or BMC-91X
- Status: Active
- Insurance carrier name and NAIC number
- Effective and cancellation dates
If the status shows “Pending,” “Canceled,” or is absent entirely, you are not currently in compliance — regardless of whether your insurance policy itself is active.
Common Mistakes That Put Carriers Out of Compliance
Letting the Policy Lapse at Renewal
The most frequent compliance failure is allowing a policy to expire while waiting for renewal paperwork to process. Even a one-day gap in coverage triggers a cancellation notice to the FMCSA. Build in at minimum 30 days of lead time before renewal and confirm the new BMC-91 is filed before the old one cancels.
Switching Insurers Without Coordinating the Filings
When moving to a new insurance carrier, the outgoing carrier files a cancellation of the BMC-91 and the incoming carrier files a new one. If these are not timed correctly, you can end up with a window of no active filing. Always confirm the new BMC-91 is live in SAFER before your prior coverage cancels.
Adding Hazmat Without Updating Coverage
Carriers who begin hauling hazardous materials after obtaining authority sometimes forget that their $750,000 policy no longer meets the minimum. Hazmat operations require $1,000,000 to $5,000,000 in coverage, and the policy must be updated and re-filed with the FMCSA before the first hazmat load moves.
Assuming State Filings Cover Federal Requirements
Some states have their own financial responsibility requirements for intrastate commerce. These state filings are separate from the federal BMC-91 requirement and do not substitute for each other. If you operate in both interstate and intrastate commerce, you may need to maintain both federal and state filings simultaneously.
What Happens Below the Minimum?
Operating with less than the required minimum — or without an active BMC-91 filing — constitutes a violation of 49 CFR Part 387. The consequences include:
- Revocation of operating authority by the FMCSA
- Civil penalties up to $16,000 per day per violation
- Out-of-service orders at roadside inspections
- Personal liability exposure if an accident occurs while underinsured

Frequently Asked Questions
Is $750,000 the minimum for all trucking companies?
No. $750,000 applies to for-hire carriers moving non-hazardous freight in vehicles over 10,001 lbs GVWR. Hazmat carriers must carry $1,000,000 to $5,000,000 depending on the commodity. Passenger carriers face $1,500,000 to $5,000,000 minimums depending on vehicle capacity.
Does cargo insurance count toward the FMCSA minimum?
No. Cargo insurance covers the value of freight and does not satisfy FMCSA financial responsibility requirements. Only primary automobile liability insurance filed via Form BMC-91 or BMC-91X counts toward the federal minimum.
What is the MCS-90 endorsement?
The MCS-90 is a mandatory policy endorsement that obligates an insurer to pay liability claims up to the federal minimum even when the underlying policy would otherwise exclude the claim. It ensures injured third parties can recover compensation regardless of policy exclusions.
How quickly does the FMCSA update its records after a new BMC-91 is filed?
Electronic BMC-91 filings typically appear in the SAFER system within 24–48 hours of submission by your insurer. Paper filings may take longer. Always confirm the filing is active in SAFER before moving freight — do not rely solely on your insurer’s confirmation.
