Liability vs. cargo insurance: what's the difference for trucking?

Liability insurance and cargo insurance protect two completely different things. Liability (auto liability) insurance covers bodily injury and property damage you cause to other people in a crash — their car, their medical bills, their property. Motor truck cargo insurance covers the freight in your trailer if it's damaged, destroyed, or stolen while in your care. One protects the public; the other protects the load.

They don't overlap, and one won't pay a claim that belongs to the other. Your liability policy specifically excludes property in your "care, custody and control" — which is exactly what your cargo policy is for. If you haul freight for hire, you generally need both.

What liability insurance covers

Motor truck (auto) liability pays third parties when you're at fault. Per i95 Insurance, liability coverage "provides for bodily injury, personal injury, property damage liability, advertising injury liability, medical payments, and product & completed operations." It does not pay to replace a shipper's freight — that exclusion is what makes cargo coverage necessary.

What cargo insurance covers

Motor truck cargo insurance, again per i95 Insurance, "provides insurance on freight or commodity that is hauled by a for-hire trucker, providing liability for cargo damaged." It responds to loss from fire, collision, or striking, and can extend to debris removal and preventing further loss to already-damaged freight. In short: it pays for the goods, not the people.

Who requires each

Liability is federally mandated. For interstate carriers hauling general, non-hazardous freight, the FMCSA minimum public liability limit is $750,000, per FreightWaves. For carriers hauling certain hazardous materials, that minimum climbs to $5,000,000. This $750,000 baseline traces to the Motor Carrier Act of 1980 and hasn't been adjusted for inflation.

Cargo insurance is generally not a federal requirement — but it's almost always a business requirement. Most freight brokers and shippers won't tender you a load without it. Per Marquee Insurance Group, "most freight brokers require a carrier to hold a minimum of $100,000 in Motor Truck Cargo (Cargo) Coverage," and "most freight brokers require the carriers they work with to possess at least $1 million in Auto Liability coverage" — well above the federal floor.

Note the difference between a broker's cargo requirement on the carrier and a broker's own financial responsibility. A property broker isn't required to carry cargo insurance themselves; instead, FMCSA requires brokers to file a $75,000 surety bond or trust fund (the BMC-84), per BuySuretyBonds, citing 49 CFR 387.307.

Bottom line

Carry liability because the government and your brokers demand it; carry cargo because a single damaged load can wipe out a month of revenue and shut off your access to freight. For an owner-operator, both are typically baked into one commercial trucking policy.
