How is Carmack liability different from a cargo insurance policy?
Carmack liability is the federal standard making an interstate motor carrier responsible for loss or damage to freight, while a motor truck cargo policy is the insurance that reimburses you when that liability attaches. One is what you owe, the other is what you collect, and they do not always match.
Carmack is close to strict liability. A carrier owes the full actual loss unless it proves the damage came from a short list of defenses: an act of God, an act of the shipper, an act of a public authority, or the inherent nature of the goods.
Your cargo policy, by contrast, is a contract full of conditions, exclusions, and sublimits. You can be fully liable and only partially covered, and the difference comes out of your operating account.
- Carmack applies to interstate movements of property under a bill of lading
- Cargo claims generally must be filed in writing within nine months of delivery
- A carrier can limit liability through a released value rate, but only with notice and shipper agreement
- Your policy pays your liability, so a loss you are not legally liable for is usually not covered
How much motor truck cargo coverage do you actually need?
Set your cargo limit at the highest single load value you haul, not the average, because coverage applies per occurrence and the average is irrelevant the day you lose the expensive load. Most general freight carriers buy $100,000, the common shipper and broker requirement, but that is a floor rather than an answer.
Commodity matters more than truck count. Dry van freight and building materials usually sit under $100,000 per trailer. Refrigerated food, pharmaceuticals, electronics, alcohol, and machinery routinely exceed it.
Also account for accumulation. A fleet running high value freight has several loads moving at once, and a terminal fire can involve more than one shipment.
- General freight commonly carries $100,000 per occurrence
- Reefer and food haulers commonly carry $150,000 to $250,000
- Electronics, pharmaceuticals, and high value machinery often require $250,000 to $1 million
- Deductibles typically run $1,000 to $5,000, higher on theft-prone commodities
- Trailer interchange is usually a separate agreement, so confirm it is covered
What exclusions cause cargo claims to be denied?
The most common denials come from conditions the carrier controls: unattended vehicle requirements, theft of excluded commodities, refrigeration breakdown without a temperature record, employee dishonesty, and damage during loading or unloading. None are obscure. They are printed in the policy and ignored until a claim.
Unattended vehicle language is the biggest one. Many policies exclude theft from a vehicle left unattended unless it was parked in a secured lot, locked, or alarmed, and the definition varies by insurer. A driver stopping for lunch can void a claim.
Targeted commodity lists are the second. Electronics, tobacco, liquor, copper, pharmaceuticals, and designer apparel are frequently excluded outright or given a much lower sublimit and stricter security requirements.
- Unattended vehicle exclusions often require a locked, fenced, lighted facility for stops over a set duration
- Employee dishonesty and driver theft are excluded on many forms unless added back
- Loading and unloading damage is often excluded when performed by someone other than the carrier
- Contraband, live animals, money, and jewelry are standard exclusions
- Improper securement is commonly excluded as an operational failure
How does reefer breakdown coverage work?
Refrigeration breakdown coverage pays for cargo spoiled by mechanical failure of the reefer unit, and nearly every policy conditions it on a working temperature recorder and a documented pre-trip inspection. Without recorder data, a spoilage claim on a $90,000 load of produce is very hard to collect.
Most forms require the unit be maintained in working order, a pre-cool before loading, and a failure lasting a minimum period, often two to six hours, before coverage attaches.
The exclusion behind the exclusion is human error. Coverage responds to mechanical failure, not to a driver setting the wrong temperature, running cycle sentry instead of continuous mode, or failing to close the doors. Those causes are common and rarely paid.
- Keep the temperature recorder download for every reefer load, plus the pre-trip record
- Confirm whether the policy requires continuous run mode for temperature-sensitive freight
- Document pre-cool and product temperature at loading
- Reefer breakdown frequently carries its own deductible, often $2,500 to $5,000
What is contingent cargo coverage and why is it contingent?
Contingent cargo coverage protects a freight broker when the hired motor carrier's own cargo insurance fails to pay, and it is called contingent because it responds only after that primary policy has been pursued and has not covered the loss. It is a backstop, not a replacement.
Brokers need it because shippers increasingly hold them responsible for freight claims they had no hand in. Negligent carrier selection claims made that exposure real, and a broker without contingent cargo pays from working capital.
The contingency is the catch. Most policies require proof the carrier had coverage at dispatch, that a claim was filed against it, and that it was denied or the carrier was insolvent. If you never verified that insurance, you may not satisfy your own policy's conditions.
- Typical contingent cargo limits run $100,000 with deductibles of $1,000 to $2,500
- Many forms exclude losses where the broker failed to vet the carrier's authority, safety rating, or insurance
- Pair contingent cargo with a contingent auto liability limit, a separate exposure
- Keep a dated certificate of insurance for every carrier on every load
How is the value of a cargo claim actually calculated?
Cargo claims are generally settled on the invoice value of the goods at destination, sometimes with freight added and salvage deducted, rather than on retail price or lost profit. That surprises shippers expecting the market value of a finished product.
Salvage drives more of the outcome than people expect. When damaged freight retains value, the insurer usually sells it and credits the proceeds against the claim. You generally cannot destroy or return freight without permission, since that eliminates the recovery and can reduce what the policy pays.
Standard cargo policies also do not pay a shipper's downstream losses, such as a canceled production run or a retailer's chargeback.
- Settlement is typically invoice value plus freight, less salvage and the deductible
- Never dispose of, donate, or destroy damaged freight without written insurer approval
- Food and pharmaceutical loads often cannot be salvaged at all under chain of custody rules
- Shipper claims for lost profit, downtime, or contractual penalties are usually outside cargo coverage
What documentation gets a cargo claim paid?
A claim file that gets paid contains the signed bill of lading, a delivery receipt noting damage when discovered, photographs, the commercial invoice, and any temperature or securement records. Assemble it within days, not weeks.
Notation at delivery matters most. A receiver who signs clean and calls two days later has made your claim harder to prove, since the presumption of proper delivery attaches at signature.
Report to your insurer immediately even if you expect to handle the claim yourself. Late notice is a coverage defense, and an early adjuster can inspect the freight and preserve evidence that disappears once a load is dumped.
- Photograph the load, securement, and trailer seal before departure on high value freight
- Have receivers note damage, shortage, or temperature on the delivery receipt before signing
- File a police report immediately for any theft, since most policies require it
- Preserve the reefer download, ELD data, and seal record for the life of the claim
