Motor truck cargo insurance protects carriers when freight is damaged, lost or stolen while in their care. But many owner-operators and small fleets find out about the fine print only after a load is lost. A cargo policy can carry exclusions, conditions and sub-limits that change how a claim is paid, or whether it's paid at all. This guide covers the most common reasons cargo claims are reduced or denied, and what you can do before a loss. For the basics of cargo coverage, see our cargo insurance page and cargo vs. motor truck cargo legal liability.
1. Unattended vehicle conditions
Many cargo policies limit or exclude theft from an unattended truck or trailer unless certain conditions are met, for example:
- The vehicle was locked, with keys removed
- Alarms or immobilizers were working and turned on
- The trailer was parked in a secured, fenced or guarded lot
- The driver was away for no more than a set time, or the stop was for a specific reason like fuel or rest
Read the definitions closely. Some policies treat a driver sleeping in the cab differently from a truck parked overnight with no one inside.
What to do: know your policy's unattended vehicle wording, plan stops in secure locations, and keep fuel and meal receipts and ELD records that show where and when you stopped.
2. Refrigeration breakdown
Spoilage of temperature-controlled freight is often excluded unless you buy a reefer breakdown endorsement. Even with the endorsement, conditions may apply:
- The unit must have been maintained, with records to prove it
- The breakdown must be sudden and accidental, not caused by running out of fuel or a wrong setpoint
- Temperature download data may be required
What to do: buy reefer breakdown coverage if you haul perishables, keep maintenance logs, pre-cool trailers, document setpoints on the bill of lading, and save temperature downloads for every load.
3. Excluded or limited commodities
Cargo policies often exclude or sub-limit certain freight, such as:
- Electronics, cell phones and computers
- Alcohol and tobacco
- Pharmaceuticals
- Jewelry, precious metals, cash and securities
- Live animals
- Hazardous materials
- Household goods
- Autos (unless the policy is written for car haulers)
If you haul a commodity on the exclusion list, the claim may be denied outright. If it's on a high-value list, a lower limit may apply.
What to do: give your broker an accurate list of everything you haul, check the commodity schedule before taking unusual loads, and get the policy endorsed before hauling new freight types.
4. Scheduled vehicle and driver requirements
Some policies cover only scheduled trucks and trailers, or only drivers listed on the policy. A loss on an unlisted trailer, or with an unlisted driver, may be denied.
What to do: report new equipment and drivers right away, and confirm whether trailer interchange or non-owned trailers are covered.
5. Limits that don't match the load
Your cargo limit may be lower than the value of a particular load, so you'd be responsible for the difference. Brokers and shippers often require specific limits, and some loads are worth far more than average.
What to do: check the load value against your limit before accepting, ask about per-load increases, and read broker-carrier agreements for liability terms that go beyond your policy. Many contracts make you liable for full value. See our guide to contract insurance requirements.
6. Improper loading, packing or securement
Policies may exclude damage caused by improper loading or packing by the shipper, or by the carrier's failure to secure cargo. Federal rules set cargo securement standards for commercial motor vehicles. See FMCSA – Cargo securement rules.
What to do: inspect loads when you can, note exceptions on the bill of lading for shipper-load-and-count freight, follow securement rules, and photograph the load before departing.
7. Wear and tear, inherent vice and delay
Most cargo policies exclude losses from inherent vice, meaning the nature of the goods themselves, such as natural spoilage or rust, as well as wear and tear, gradual deterioration, and delay or loss of market.
8. Mysterious disappearance and shortage
Unexplained shortages discovered at delivery, without evidence of theft, may be excluded or require proof. Sealed trailers and documented counts help.
9. Late notice and missing documentation
Policies require prompt notice. Delays can hurt your claim, especially for theft, where police reports matter.
Documents to keep for every load:
- Signed bill of lading with seal numbers
- Rate confirmation and broker-carrier agreement
- Photos at pickup and delivery
- ELD and GPS records
- Temperature downloads for reefer loads
- Police report for any theft
- Delivery receipt noting exceptions
Interstate household goods carriers
Movers of household goods face specific federal rules on liability and valuation options. See FMCSA – Protect your move. Standard cargo policies often exclude household goods, so movers need coverage written for that business.
Cargo theft prevention
- Avoid parking loaded trailers in unsecured areas, especially in the first hours after pickup.
- Use high-security locks on kingpins, gladhands and doors.
- Use GPS tracking on trucks and trailers.
- Be cautious of fictitious pickups and identity fraud; verify brokers and shippers.
- Don't share load details on social media or over open channels.
