Motor truck cargo insurance is one of the most important — and most misunderstood — coverages in commercial trucking. While most owner-operators understand they need liability insurance, cargo coverage is often treated as an afterthought. That is a costly mistake. A single large cargo claim can exceed your annual insurance premium many times over. This guide covers everything you need to know about motor truck cargo insurance: what it covers, what it excludes, how limits and deductibles work, and how your cargo type affects what you pay.
What Is Motor Truck Cargo Insurance?
Motor truck cargo insurance (also called cargo insurance or freight insurance) is a commercial insurance product that protects the property of others while it is in your care, custody, and control as a for-hire motor carrier. If the freight you are hauling is damaged, destroyed, or stolen while in transit, your cargo policy is what pays for it.
It is important to understand that cargo insurance covers the shipper’s goods, not your truck or equipment. Physical damage on your truck is a separate coverage. Cargo insurance is liability-based — you are legally responsible for the safe delivery of the freight, and this policy covers that liability.
What Motor Truck Cargo Insurance Covers
A standard cargo policy covers loss or damage to freight from the following causes:
- Collision or overturn — damage to freight resulting from a truck accident
- Fire — including fire in the trailer or cab that damages the load
- Theft — cargo stolen from the trailer or vehicle; note that most policies require signs of forced entry for theft claims to be covered
- Water damage — rain, flooding, or water intrusion during transit (often subject to exclusions)
- Loading and unloading accidents — damage occurring during the process of loading or unloading the freight
- Stranding — freight that must be unloaded because the truck has broken down
Common Cargo Insurance Exclusions
Cargo policies are not all-risk (though some specialty policies approach this). Standard exclusions include:
- Unattended vehicle exclusion: Many policies will not pay theft claims if the truck was left unattended without being locked or in a secure facility. Read your policy carefully — some carriers require the truck to be in a secured location overnight.
- Mysterious disappearance: Cargo that cannot be accounted for but was not provably stolen is often excluded.
- Improper packing or inherent vice: Damage resulting from how the shipper packed the goods, or from the inherent nature of the commodity (e.g., perishables that spoil due to their own nature).
- War and nuclear exclusions: Standard policy exclusions not relevant to most truckers.
- Delay: Loss of market, delay penalties, and consequential damages are typically excluded. Cargo insurance pays the value of the damaged goods, not lost profits.
- Electronics and high-value items: Many cargo policies have sublimits or exclusions for electronics, pharmaceuticals, jewelry, and other high-value commodities. If you regularly haul these, you need a specialty endorsement.
Cargo Insurance Limits and Deductibles
Cargo insurance is sold in per-occurrence limits, typically ranging from $25,000 to $250,000 or more. The right limit depends on what you haul. If your typical load is worth $50,000 in retail value, a $50,000 limit may be sufficient. If you haul electronics or pharmaceuticals with load values of $200,000+, you need higher limits.
Common cargo limits by commodity type:
- General dry freight: $100,000 is standard; many shippers require this minimum
- Refrigerated cargo: $100,000 to $200,000 depending on commodity
- Electronics or pharmaceuticals: $250,000 to $500,000 or custom limits
- Auto hauling: Based on value of vehicles being transported
Deductibles typically range from $500 to $5,000 per occurrence. Higher deductibles reduce your premium but mean more out-of-pocket cost when a claim occurs. For high-frequency, low-severity commodity types (like produce), a lower deductible may be worth the extra premium. For low-frequency, high-severity loads, a higher deductible often makes sense.
Refrigeration Breakdown Endorsement
If you haul refrigerated or frozen cargo, your standard cargo policy may not automatically cover losses caused by a mechanical breakdown of your refrigeration unit. A refrigeration breakdown endorsement (also called reefer breakdown coverage) extends the policy to cover cargo losses resulting from temperature excursions caused by mechanical failure of the reefer unit.
This endorsement typically adds $200 to $600 per year to your cargo premium but is essential for anyone hauling temperature-sensitive goods. Without it, a reefer breakdown that destroys a $100,000 load of frozen seafood could be entirely excluded from coverage. Brokers and shippers who handle temperature-sensitive freight often require this endorsement as a condition of doing business with you.
How Cargo Type Affects Your Rate
The commodity you haul is the primary driver of your cargo insurance premium, after your limit and deductible selection. Here is how common cargo types are generally rated:
- General dry freight (boxes, pallets, consumer goods): Most favorable rates. This is the baseline commodity class.
- Refrigerated/perishables: Moderately higher rates due to refrigeration breakdown exposure and sensitivity of the cargo.
- Electronics, computers, pharmaceuticals: High-value commodities with high theft frequency receive significantly higher rates. Many carriers apply sublimits or require specific security protocols.
- Alcohol and tobacco: High theft target; higher rates and sometimes sublimits apply.
- Building materials and metals: Generally favorable rates; heavy but low theft value.
- Household goods: Higher rates due to the difficulty of accurately valuing contents and high frequency of claims.
- Automotive parts and vehicles: Moderate to high rates depending on value and loss history.
Do Brokers and Shippers Require Cargo Insurance?
Yes — virtually every freight broker and shipper will require you to carry cargo insurance as a condition of being approved to haul their loads. The standard minimum requirement in the market is $100,000 per occurrence. Many larger shippers and brokers require $250,000 or more. Some high-value commodity shippers have their own specific requirements that go beyond standard market minimums.
You should carry cargo insurance even if FMCSA does not specifically require it for your operation type. The financial exposure from a large cargo loss is too significant to self-insure, and you will not be able to work with most brokers or shippers without it.

Frequently Asked Questions: Motor Truck Cargo Insurance
How much does motor truck cargo insurance cost?
Motor truck cargo insurance typically costs $1,500–$5,000 per year for most owner-operators, depending on the commodity type, cargo value limits, and your loss history. Dry van freight at standard limits ($100,000) runs on the lower end. High-value commodities (electronics, pharmaceuticals), refrigerated loads, or specialty cargo push premiums higher. Most commercial trucking policies bundle cargo coverage with primary liability, so your total package cost reflects both.
What does motor truck cargo insurance NOT cover?
Motor truck cargo insurance typically excludes: cargo damaged by improper loading (if done by the shipper), inherent vice (goods that deteriorate naturally), contraband or illegal goods, cargo in an unattended vehicle that was left unlocked, and losses caused by war or government seizure. Some policies also exclude refrigeration breakdown unless specifically endorsed. Always read your policy’s exclusions before assuming full coverage.
Is motor truck cargo insurance required by FMCSA?
FMCSA does not mandate motor truck cargo insurance for most general freight operations — it mandates liability insurance (minimum $750,000 for general freight). However, many shippers and brokers contractually require cargo insurance as a condition of load assignment, typically $100,000 per occurrence minimum. For household goods carriers, FMCSA does require cargo insurance under 49 CFR Part 387.
What cargo value limit should I carry?
Most owner-operators carry $100,000 in cargo coverage as a minimum, which satisfies the majority of load broker requirements. If you haul high-value freight (electronics, auto parts, pharmaceuticals), $250,000 or higher may be required by your shippers or advisable based on load values. Your cargo limit should match the maximum value of any single load you’re likely to haul — don’t underinsure to save $200/year on premium.
