Quick Answer: What Insurance Do Commercial Trucks Need?
Commercial trucks operating in interstate commerce must carry federally mandated insurance minimums set by the FMCSA (Federal Motor Carrier Safety Administration). Requirements depend on what you haul and where you operate.
Federal Minimums:
- General freight: $750,000 liability
- Household goods: $750,000 liability
- Hazardous materials: $1,000,000 to $5,000,000 liability
- Oil transport: $1,000,000 liability
These are minimums. Most carriers need higher limits for contracts and broker access.
FMCSA Insurance Requirements
Required Liability Limits by Cargo Type
| Cargo Type | Minimum Liability | Notes |
|---|---|---|
| General freight (non-hazmat) | $750,000 | Most common requirement |
| Household goods movers | $750,000 | Additional cargo insurance required |
| Hazardous materials | $1,000,000 | Class A/B explosives, poison gas |
| Hazmat (oil, hazardous waste) | $1,000,000 | Petroleum, radioactive materials |
| Hazmat (high-risk) | $5,000,000 | Large quantity radioactive, certain explosives |
| Passengers (for-hire) | $1,500,000-$5,000,000 | Based on seating capacity |
Who Must Comply?
Interstate carriers that:
- Operate vehicles over 10,001 lbs GVWR
- Transport passengers for compensation
- Haul hazardous materials requiring placards
- Cross state lines for business purposes
Intrastate carriers: Subject to state requirements, which often mirror or exceed federal minimums.

Owner-Operator Insurance Requirements
Leased to a Motor Carrier
If you're leased on, the carrier's insurance covers you while under dispatch. You may need:
- Bobtail/Non-trucking liability: When not under dispatch
- Physical damage: Carrier's policy doesn't cover your truck
- Occupational accident: Not workers' comp, but similar protection
Operating Under Your Own Authority
Required to get authority (MC number):
- Primary liability: $750,000 minimum (higher for hazmat)
- BMC-91 or BMC-91X filing with FMCSA
- BOC-3 (process agent designation)
Also needed for business:
- Cargo insurance: $100,000 typical
- Physical damage: To protect your investment
- General liability: For non-trucking business operations
DOT and FMCSA Filing Requirements
BMC-91 and BMC-91X
Insurance filings that prove you meet FMCSA requirements.
- BMC-91: Filed by insurance company directly
- BMC-91X: Filed by insurance company on your behalf as an insurer
When Required:
- Before receiving operating authority
- When changing insurance companies
- After any policy cancellation
What Happens if Coverage Lapses?
- Insurance company notifies FMCSA (30-day notice before cancellation)
- Operating authority becomes inactive
- You cannot legally operate
- Loads get pulled from load boards
- Reinstatement requires new BMC filing
State-Specific Requirements
Intrastate Operations
States set their own minimums for trucks operating only within state borders:
| State | Minimum Liability | Notes |
|---|---|---|
| California | $750,000 | Matches federal |
| Texas | $500,000 | Lower than federal |
| Florida | $300,000 | Well below federal |
| New York | $750,000 | Matches federal |
| Ohio | $300,000 | Lower than federal |
Important: If you ever cross state lines, you need federal-level coverage.
State Filing Requirements
Many states require separate filings (Form E or equivalent) for intrastate authority.

- Owner-operators (vs. fleets)
- History of claims or violations
- Operating in high-risk states (CA, NY, FL)
Lower premiums for:

- Good CSA scores
- Regional/local operations
- Experienced drivers (3+ years)
- Fleet discounts
- Higher deductibles
- Safety programs and dash cams
Getting Your Authority: Insurance Steps
Step-by-Step Process
-
Decide your operation type - What will you haul? Interstate or intrastate?
-
Get insurance quotes first - Apply before filing for authority. Insurers need to file BMC-91.
-
Apply for authority - File with FMCSA through Unified Registration System.
-
Pay FMCSA fees - $300 for MC authority.
-
File BOC-3 - Process agent designation (about $30-$50).
-
Insurance company files BMC-91 - This activates your authority.
-
Wait for authority activation - Typically 21+ days after application.
-
Begin operations - Only after authority shows "Active" in FMCSA system.
Common Exclusions and Gaps
What Commercial Truck Insurance Doesn't Cover
- Intentional damage
- Wear and tear on your equipment
- Mechanical breakdown (need separate MTC coverage)
- Employee dishonesty (need crime coverage)
- Cargo you don't declare to your insurer
- Commodities excluded in your policy (check carefully)
Gap Issues for Owner-Operators
- No physical damage when leased: Carrier policy covers liability, not your truck
- Bobtail gap: Leased operator without bobtail coverage has no liability when off-dispatch
- Downtime: Standard policies don't cover lost income—need rental reimbursement endorsement
FAQ
What is the minimum insurance for a semi truck?
For interstate freight hauling, $750,000 liability is the federal minimum. Hazmat carriers need $1,000,000-$5,000,000 depending on cargo type.
Do I need cargo insurance?
FMCSA doesn't mandate specific cargo limits, but most brokers and shippers require $100,000 minimum. Household goods movers have specific cargo requirements.
What's the difference between primary liability and bobtail?
Primary liability covers you while under dispatch or hauling freight. Bobtail covers non-business use when you're not under load.
How long does it take to get trucking authority?
About 21-25 days after application, provided insurance filings (BMC-91) are complete. Insurance must be in place before authority activates.
Why is new authority insurance so expensive?
Insurers view new carriers as high risk. About 30% of new trucking companies fail in the first year. Premiums typically decrease after 2 years of clean operation.
Do owner-operators need their own insurance?
If operating under your own authority, yes—full coverage. If leased to a carrier, their policy covers you under dispatch, but you need bobtail and physical damage for your truck.
What happens if my insurance lapses?
FMCSA deactivates your authority. You cannot legally operate, and reinstatement requires new insurance filings.
