Understanding Liability, Cargo, and Physical Damage Coverage

If you remember one thing about commercial policies, make it this: each coverage answers a different question. Liability answers for other people. Cargo answers for the freight. Physical damage answers for your equipment. A loss can trigger one, two or all three, and the limits do not borrow from each other.

Auto liability: damage you cause to others

This is the required coverage and usually the largest premium line. It pays third-party bodily injury and property damage arising out of the operation of a covered vehicle, plus legal defense. For interstate authority the federal minimum is generally $750,000, with $1,000,000 being the practical standard because brokers and shippers require it. Hazmat and passenger operations have higher requirements.

What it does not do: it does not pay for your truck, your trailer, your injuries or your freight. Those are separate coverages, and assuming liability covers them is one of the most common misunderstandings in the industry.

Motor truck cargo: the freight you are hauling

Cargo coverage responds when the freight is damaged, destroyed or stolen while in your care, custody and control. The form matters more than the limit. Read the commodity list, the theft conditions and the exclusions before you assume a load is covered.

• Excluded or restricted commodities are common: alcohol, tobacco, pharmaceuticals, live animals, high-value electronics, jewelry and money.
• Theft conditions may require a locked, attended or fenced-and-lit location, and unattended-trailer theft is frequently limited or excluded.
• Refrigerated loads usually need a reefer breakdown endorsement with its own deductible and maintenance-record conditions.
• Cargo deductibles are per occurrence and often higher than physical damage deductibles.

Physical damage: your own tractor and trailer

Physical damage splits into collision and comprehensive. Collision covers impact regardless of fault; comprehensive covers theft, fire, vandalism, falling objects, flood and animal strikes. Valuation is the detail that decides your check: stated value pays the lesser of the stated amount or actual cash value, while actual cash value pays market value at the time of loss, minus depreciation.

If you financed the truck, check whether the lender requires a specific valuation method and whether you need gap coverage. A depreciated payout on a five-year-old tractor can leave a real balance on the loan.

Where the three meet in a single accident

Consider a rollover on the Turnpike with a loaded reefer. Liability responds to the other driver's injuries and the guardrail. Physical damage responds to your tractor and trailer, subject to your deductible. Cargo responds to the spoiled load, subject to its own deductible and to whether refrigeration failure or the impact caused the loss. Three claims, three adjusters, three deductibles, one accident.
