Motor Truck Cargo Insurance: Coverage for Freight Carriers in 2026

Motor truck cargo insurance is the line that protects the freight you’re hauling — not your truck, not your liability to third parties, but the actual goods in your trailer. It’s also one of the most commonly misunderstood coverage lines in commercial trucking. Carriers frequently discover their cargo policy doesn’t cover their actual loads only after a significant loss reveals an exclusion they didn’t know existed.

What Motor Truck Cargo Insurance Covers

Cargo insurance covers physical loss or damage to the freight while in your care, custody, and control — from the time you accept the load through delivery. Standard covered perils include accident and collision damage, theft, fire, and loading/unloading damage. The policy pays the shipper’s or consignee’s claim for the value of the damaged or lost freight.

Coverage triggers and exclusions vary by policy form. The most common exclusions that catch carriers off-guard:

• Refrigeration breakdown: Most standard cargo policies exclude spoilage from mechanical refrigeration failure. The cargo froze because the reefer unit broke — that’s typically excluded. You need a specific temperature-controlled cargo endorsement or a specialty policy for refrigerated freight.
• Electronics and high-value commodities: Many policies cap coverage on electronics, pharmaceuticals, tobacco, alcohol, and jewelry regardless of stated limits. A $200,000 cargo limit may only apply $50,000 to electronics under a sublimit.
• Unattended vehicle: Theft from an unattended or unsecured vehicle may be excluded or sublimited. Know your policy’s overnight parking and security requirements.
• Acts of God: Some policies exclude flood, earthquake, and wind damage — particularly relevant for Gulf Coast operations during hurricane season.

Setting the Right Cargo Limits

The most common cargo insurance mistake is setting limits based on average load values rather than maximum. You’re not insuring your average haul — you’re protecting against the worst-case load. A carrier running general freight might average $40,000 per load but occasionally haul $180,000 loads. Setting limits at $75,000 leaves that high-value load underinsured by $105,000.

Review your freight bills or bills of lading for the past 12 months and identify your maximum load value. Set your cargo limit at or above that number. If your business is growing, factor projected load values into the limit decision — adjusting limits mid-term typically triggers a pro-rated additional premium.

Freight Broker Contingent Cargo

Freight brokers don’t haul freight themselves — they arrange transportation by connecting shippers with carriers. Brokers have a different but real cargo liability exposure: when a carrier they’ve booked fails to pay a cargo claim (carrier is underinsured, goes bankrupt, or denies the claim), the shipper often pursues the broker. Contingent cargo insurance covers the broker’s liability in those scenarios — it responds when the carrier’s primary cargo policy doesn’t.

Brokers without contingent cargo insurance are personally exposed to cargo claims that run through their arrangements. Most shippers and shipper contracts require brokers to carry contingent cargo. Standard limits are $100,000–$250,000; limits should match the highest-value loads you regularly broker.
