Trucking Company Insurance Requirements: Coverage Types, Minimums, and What Carriers Get Wrong

Insurance is the gating requirement for everything else in your trucking operation. FMCSA will not activate your MC authority until your insurer files proof of coverage directly with the agency. Brokers will not tender loads until your Certificate of Insurance meets their minimums. Lenders will not release financed equipment without physical damage coverage on file. Understanding exactly what trucking company insurance requirements apply — and in what order they matter — is the first operational decision you make as a carrier.

FMCSA Minimum Liability Requirements

Under 49 CFR Part 387, FMCSA sets federal minimums for primary auto liability based on the type of freight you haul and the weight of your vehicle. These are the numbers that determine whether your authority gets activated.

• General freight (non-hazardous, vehicles over 10,001 lbs): $750,000 minimum
• Hazardous materials (certain classifications): $1,000,000 minimum; $5,000,000 for highest-risk materials
• For-hire carriers operating vehicles under 10,001 lbs (small carriers): $300,000 minimum
• Household goods carriers: $300,000 minimum

These numbers are the legal floor. They are not the operational floor. Most freight brokers require $1,000,000 in primary auto liability regardless of cargo type, and many require it as a hard condition in their carrier agreements. If you launch with the federal minimum of $750,000 and a broker's rate confirmation specifies $1,000,000, you cannot haul that load until you increase your limits. The annual premium difference between $750K and $1M for a new single-truck authority is typically $400–$800. That is not the reason to skip the upgrade.

BMC-91/91X: The Filing That Actually Activates Your Authority

Your insurance policy does not automatically notify FMCSA that you are covered. Your insurer must file Form BMC-91 or BMC-91X directly with FMCSA through their electronic filing system. BMC-91 covers single-limit liability. BMC-91X covers excess or umbrella liability. Without one of these on file, your MC authority application will not activate — and if your policy lapses after activation, your insurer files a notice of cancellation that triggers automatic authority revocation proceedings.

This is a mechanical process your insurance agent handles, but you need to confirm it happened. Log into FMCSA's SAFER system (safer.fmcsa.dot.gov) after your policy is issued and verify that your insurance record shows an active filing from your insurer. Agents who are unfamiliar with trucking occasionally issue compliant policies without completing the FMCSA filing step. Your authority cannot activate until that filing is in FMCSA's system.

Form MCS-90: What It Is and Why It Has to Be on Your Policy

The MCS-90 endorsement is a mandatory attachment to your primary auto liability policy for all for-hire interstate carriers subject to 49 CFR Part 387. It is not a separate product — it is a form your insurer adds to your existing policy at no additional premium. Its purpose is to ensure that members of the public injured by your commercial vehicle can collect compensation even when your policy would otherwise not cover the loss.

Here is why that matters in practice: if a driver who is explicitly excluded from your policy causes an accident, your insurer could ordinarily deny the claim. With the MCS-90 in force, the insurer must still pay the judgment to the injured third party — and then pursue reimbursement from you (the carrier) after the fact. The MCS-90 is not protection for you. It is protection for the public, and it creates a direct financial liability for carriers who allow excluded drivers to operate, carry passengers in violation of policy terms, or otherwise create coverage exclusion scenarios.

What happens if your insurer does not file the MCS-90? Your authority application will not be approved. FMCSA specifically requires the endorsement as part of the insurance filing process. If an agent issues a policy that should include the MCS-90 but omits it — which happens when agents unfamiliar with trucking regulations process the application — the insurer is still potentially liable under the endorsement by statute. The agent's error does not eliminate the obligation; it just creates a mess for everyone involved.

Cargo Insurance: Not Federally Required, But You Cannot Work Without It

The federal cargo insurance minimum for interstate carriers is $5,000 per vehicle or $10,000 per occurrence under 49 CFR Part 387. In 2025, that number does not cover a single pallet of consumer electronics. Brokers set their own cargo coverage requirements as a condition of carrier approval, and $100,000 per occurrence is the baseline for general freight. Temperature-sensitive freight, pharmaceuticals, electronics, and specialty commodities typically require $250,000 or higher.

Proof of cargo coverage is filed with FMCSA using Form BMC-34, separate from the liability filing. Your Certificate of Insurance must show cargo coverage as a distinct line item with its own per-occurrence limit. Brokers check this. A COI showing only auto liability without a visible cargo line will be rejected during the broker's carrier qualification review.

Cargo insurance and liability insurance cover different things. Liability covers bodily injury and property damage to third parties. Cargo covers the shipper's freight while it is in your custody. A stolen load, a rollover that destroys the freight, a refrigeration unit failure on a temperature-controlled load — all of these are cargo claims. The broker is liable to the shipper for the full value of the load and contractually shifts that risk to you through carrier agreements that require cargo coverage matching the freight value.

General Liability vs. Primary Auto Liability: What Covers What

Primary auto liability covers bodily injury and property damage that occurs as a result of your vehicle's operation on the road. A collision that injures another motorist — auto liability. A pedestrian struck at an intersection — auto liability. Damage to another vehicle in a rear-end accident — auto liability.

General liability (commercial general liability, or CGL) covers bodily injury and property damage that occurs outside of vehicle operations. A driver who drops a pallet on a dock worker at a shipper's facility — general liability. Property damage caused by an employee during a delivery handoff — general liability. Injuries that occur on your business premises — general liability. FMCSA does not require general liability. Direct shippers — national retailers, manufacturers, distribution operations — require it as a carrier qualification condition. $1,000,000 per occurrence is standard. If you plan to work directly with shippers rather than exclusively through brokers, general liability is non-optional.

Bobtail and Non-Trucking Liability: When You Need It and When You Don't

Bobtail insurance covers your tractor when it is operating without a trailer. Non-trucking liability covers your personal use of the truck when it is not under dispatch — driving home after a delivery, running errands, operating outside the scope of your motor carrier duties.

Whether you need bobtail coverage depends on your operating model. Owner-operators who lease to a carrier (operating under someone else's authority) typically need bobtail coverage because the carrier's insurance covers the truck only when it is dispatched. When the truck is not under dispatch, the carrier's policy does not cover it — and the owner-operator's personal auto policy excludes commercial trucks. That coverage gap is exactly what bobtail insurance fills.

Owner-operators who have their own authority and operate under their own primary auto liability policy have different exposure. Their primary policy covers the truck during commercial operation. What it may not cover is non-commercial personal use. Non-trucking liability fills that gap. Annual cost for non-trucking liability is typically $400–$900 for a single truck, depending on territory and driving history.

If you are leasing to a carrier and that carrier tells you their insurance covers everything, get that in writing and verify it with your own insurance agent before you drop your own coverage. Carriers' policies vary. Assuming you are covered is not a compliance strategy.

Physical Damage Coverage: Lender Requirements vs. Operational Reality

Physical damage covers your own equipment — collision (damage from an accident), comprehensive (theft, fire, weather, vandalism), and sometimes specified perils. FMCSA does not require it. Your lender does.

If you financed your truck, the loan agreement almost universally requires collision and comprehensive coverage for the financed vehicle, with the lender listed as a loss payee on the policy. The lender's interest in the equipment is what drives the requirement. If the truck is totaled and there is no physical damage coverage, the lender has no recourse to recover the outstanding loan balance. Failing to maintain physical damage on financed equipment can trigger the lender's own force-placed insurance — at significantly higher cost to you.

If you own your truck outright, the decision is yours. Operating a $120,000 truck without physical damage coverage is a calculated risk. A single total-loss event — fire, theft, major accident — ends your operation unless you have the capital to replace the equipment. Most new carriers do not. Physical damage on a truck valued at $80,000–$150,000 typically runs $3,500–$8,000 annually depending on age, use, and driver history.

What Insurance Companies Actually Look At

Trucking insurance is underwritten differently than personal auto insurance. The underwriter is evaluating the risk profile of your entire operation, not just a driver's driving record.

• CSA scores: Your FMCSA Compliance, Safety, Accountability scores are public and insurers review them. High scores in Unsafe Driving, Hours of Service Compliance, or Vehicle Maintenance signal elevated risk and increase premiums or result in declination.
• Driver history: MVR (Motor Vehicle Record) for each driver. DUIs, major violations, or multiple at-fault accidents in the past 3–5 years will increase premiums significantly or make coverage unavailable through standard markets.
• Equipment age: Older trucks (10+ years) with high mileage are rated as higher risk for mechanical failure and breakdown incidents. Some insurers set maximum age limits for covered equipment.
• Operating radius: Local, regional, and national operations carry different risk profiles. Longer-haul carriers crossing multiple states face different road and weather conditions.
• Commodity type: Dry van general freight is rated differently than flatbed, tanker, refrigerated, or hazmat. Higher-risk commodities produce higher premiums.
• Years in operation: New authorities pay more. A carrier with 0–2 years of operating history is an unknown risk. Premiums for new authorities are typically 20–40% higher than for established carriers with clean records.

Annual Premium Ranges for New Authorities: Real Numbers

New authorities consistently pay higher premiums because insurers have no loss history to price against. Here is what a single-truck new authority operating dry van general freight should expect in the current market:

• Primary auto liability ($1M): $8,000–$14,000 annually
• Cargo insurance ($100K): $1,800–$3,500 annually
• Physical damage (truck valued at $80K–$120K): $3,500–$7,000 annually
• Non-trucking liability: $400–$900 annually
• General liability ($1M): $900–$2,000 annually
• Total package (all coverages): $15,000–$28,000 annually for a new single-truck authority

Hazmat carriers and tanker operations pay more. Carriers with poor CSA scores or drivers with violation history pay significantly more — or cannot get coverage through standard markets and must use specialty insurers at higher cost. After 2–3 years of clean operating history, premiums typically decrease by 15–30% at renewal.

Common Mistakes That Create Compliance Gaps

Letting coverage lapse is the most operationally catastrophic mistake. FMCSA monitors insurance filings in real time. When your insurer cancels or non-renews, they file a cancellation notice with FMCSA. If new coverage is not filed within the required timeframe, FMCSA initiates authority revocation. Reinstatement requires filing new insurance and completing a reinstatement process that takes two to four weeks — during which you cannot legally haul. Set renewal reminders at 60 and 30 days. Do not wait for your insurer to remind you.

Incorrect commodity classification creates both coverage gaps and premium disputes. If your policy covers dry van general freight and you accept a load of refrigerated produce, you may have a cargo coverage gap. If your policy covers standard commodities and you haul electronics or pharmaceuticals without endorsing the policy for high-value cargo, a claim on those loads may be denied or limited. Tell your insurer exactly what you haul. Inaccurate commodity descriptions on your policy application are a basis for claim denial.

Wrong deductible selection creates cash flow risk. Many new carriers choose high deductibles ($5,000–$10,000 on cargo or physical damage) to reduce annual premiums. That math only works if you have the cash to cover the deductible when a claim occurs. A $10,000 deductible on a cargo claim for a carrier running on thin margins can mean not making payroll. Choose deductibles you can actually cover from operating reserves.

Missing the MCS-90 on your policy is more common than it should be. Confirm with your agent in writing that the MCS-90 endorsement has been attached and filed with FMCSA. Verify it appears on your FMCSA record before you begin operations. An agent who is unfamiliar with FMCSA filings can issue an otherwise-compliant policy that omits this required endorsement, and the deficiency may not be discovered until you have an authority activation problem.

Know the Requirements Before You Sign a Policy

Insurance decisions made at authority application time follow your operation for years. The policy structure you choose — coverage types, limits, deductibles, commodity classifications — determines which loads you can haul, which brokers will work with you, and how exposed you are when something goes wrong. Getting it right from the beginning is significantly less expensive than correcting it after the fact.
