The Coverage Field Guide

What trucking insurance actually covers

It isn't one policy — it's a package of coverages, each protecting a different part of your operation. Here's a quick guide to every one: what it does, the limits to expect, and where to go deeper.

Only two are required by the FMCSA — Auto Liability and Motor Truck Cargo. The rest protect what those two don't.

Protection comes in four layers

Package them, and you're covered end to end. Here's how they fit together.

01

Your Truck

Coverage for your truck & trailer

Physical Damage

Recommended

Comprehensive and collision that repair or replace your own tractor and trailer after a crash, fire, theft, or weather — the one thing your liability policies never pay for.

Typical limitYour truck & trailer's stated or actual cash value. Lenders require it on financed equipment.

Trailer Interchange

Contract-driven

Covers non-owned trailers and chassis you pull under a written interchange or UIIA agreement at ports, rail yards, and terminals.

LimitSet by the interchange / UIIA agreement you sign.
02

Your Cargo

Coverage for the freight you haul

Motor Truck Cargo

Required

Pays for the freight in your care when it's lost, stolen, or damaged — the coverage brokers verify before they'll tender you a load.

Required limit$100,000 minimum for most brokers · higher for high-value commodities.

Per-Shipment Cargo

As needed

An excess cargo limit for a single high-value load that exceeds the limit on your standard policy — bought load by load.

LimitPurchased per shipment, up to the load's value.

Reefer / Mechanical Breakdown

Cargo add-on

An endorsement on your Motor Truck Cargo policy that pays for a refrigerated load lost to spoilage when the reefer unit or its power source fails — a loss standard cargo coverage typically excludes.

LimitAdded to your cargo policy; covers the value of the load at risk.
Included in many cargo programs — ask your specialist.
03

Your Drivers

Coverage for the people behind the wheel

Occupational Accident

Driver injury

Medical, disability, and death benefits for a driver hurt on the job — common for owner-operators and 1099 contractors.

LimitBenefit levels (medical, disability, AD&D) are chosen up front when the plan is set.

Workers' Compensation

Often required

Statutory injury coverage for W-2 employee drivers — required in most states once you have employees.

LimitStatutory — coverage is set by your state's requirements.

Bobtail / Non-Trucking Liability

For leased-on

Two commonly confused liability coverages that protect a leased-on driver running without a load or off dispatch.

Typical limitCommonly $1,000,000, set to match your carrier lease.
04

Everyone Else

Coverage for your liability to others

Commercial Auto Liability

Required

Pays for injury or property damage you cause to others — the coverage that keeps your authority active.

Required limit$750,000 FMCSA minimum · $1,000,000 required by most brokers · higher for hazmat.

Truckers General Liability

Premises only

Different from a standard business's general liability: a trucker's GL is premises-based only. It covers injury or property damage at your own location — an office, yard, or terminal, like a visitor slipping in your lot. Anything arising from operating, loading, or unloading a truck is excluded and handled by your auto liability.

Common limit$1,000,000 per occurrence / $2,000,000 aggregate (the UIIA standard).

Excess / Umbrella

Higher limits

Stacks additional limits on top of your primary policies when a contract — or a severe claim — exceeds them.

LimitAdds $1M–$5M or more over your primary auto, GL, and WC limits.

Coverage questions, answered

What truck insurance is legally required?

The FMCSA requires two coverages to keep your authority active: Commercial Auto Liability ($750,000 minimum, though most brokers require $1,000,000) and, for most operations, Motor Truck Cargo. Everything else is optional under the law but protects exposures those two don't.

What's the difference between physical damage and cargo coverage?

Physical Damage covers your truck and trailer — the equipment. Motor Truck Cargo covers the freight inside. They're separate policies: one accident can damage both, and each is paid by its own coverage.

Do I need cargo insurance if the broker already has it?

Yes. A broker's contingent cargo policy protects the broker, not you, and usually only pays when your coverage fails to. As the carrier, the freight is in your care, so brokers require your own Motor Truck Cargo — usually at least $100,000.

What's the difference between bobtail and non-trucking liability?

Both apply to leased-on owner-operators. Bobtail covers the truck when operated without a trailer; non-trucking liability covers it during personal, off-dispatch use. Your lease usually dictates which one you must carry.

How much liability coverage do brokers require?

The federal minimum is $750,000, but nearly every broker requires $1,000,000, and many contracts now ask for higher limits backed by an excess or umbrella layer. Hazmat and specialized operations carry higher federal minimums.
