What is Motor Truck Cargo Insurance? Definition & Compliance Guide

Motor truck cargo insurance is a commercial insurance policy that covers the freight or cargo a motor carrier is transporting against loss or damage while in transit. It protects the carrier - and, depending on policy terms, the shipper or broker - from financial liability when cargo is damaged, stolen, or destroyed during hauling operations.

Motor truck cargo insurance is a distinct coverage from commercial auto liability and is routinely required by broker-carrier agreements, shipper contracts, and freight broker agreements. Understanding what it covers, what it excludes, and how to read it on a certificate of insurance is essential for anyone in the transportation and logistics chain.

What Motor Truck Cargo Insurance Covers

Motor truck cargo policies cover physical loss or damage to cargo while it is in the care, custody, and control of the motor carrier. Covered causes of loss on a broad form typically include collision, overturn, fire, theft, water damage, and loading or unloading accidents. Coverage applies from the time freight is picked up until it is delivered and accepted by the consignee.

Key coverage elements to understand:

• Cargo limit per vehicle or per occurrence - the maximum the insurer pays for any one loss
• Refrigeration breakdown - often excluded unless specifically endorsed; critical for temperature-sensitive cargo
• Theft by misappropriation - some policies exclude cargo stolen by the driver; confirm for high-value freight
• Earned freight - some policies include recovery of freight charges lost due to a covered cargo loss

How Motor Truck Cargo Differs from Auto Liability

Commercial auto liability covers bodily injury and property damage to third parties arising from the operation of covered vehicles. It does not cover the cargo being hauled. A truck accident that injures another driver is an auto liability claim. Cargo damaged in that same accident is a motor truck cargo claim. These are separate policies covering separate exposures, and both are routinely required by contract.

Confusing auto liability limits with cargo limits is a common mistake when reviewing carrier certificates. A carrier with a $1 million auto liability limit may carry only $100,000 in cargo coverage - inadequate for high-value freight shipments.

What Broker-Carrier Agreements Require

Freight broker-carrier agreements routinely specify minimum cargo insurance requirements as a condition of booking loads. Common requirements include:

• $100,000 per occurrence as a minimum - frequently the floor for standard dry van freight
• $250,000 to $500,000 for high-value electronics, pharmaceuticals, or specialty commodities
• $1,000,000 or higher for hazardous materials, fine art, or large-volume shipments

Many broker-carrier agreements also specify that the broker or shipper must be listed in the policy (or named on the certificate) and that the carrier must notify the broker before policy cancellation. These requirements must be verified on the certificate, not assumed.

How to Verify Motor Truck Cargo on a COI

Motor truck cargo coverage does not appear as a standard coverage line on the ACORD 25. It is typically shown in the "Other" coverage section, in a separate cargo certificate, or in the description of operations. Some carriers provide a separate ACORD 25 or a proprietary certificate specifically for cargo coverage.

When reviewing a carrier's insurance certificate for cargo compliance:

1. Confirm motor truck cargo is listed as a separate coverage line - not lumped with auto liability
2. Verify the per-occurrence or per-load limit meets the contract minimum
3. Check for commodity exclusions - some cargo policies exclude electronics, liquor, tobacco, or pharmaceuticals
4. Confirm the policy period is active and covers the contract term
5. Verify the broker or shipper is listed as certificate holder and that cancellation notification terms are noted
6. Check whether refrigeration breakdown or temperature-controlled cargo is covered if relevant to the freight type

Coverage Gaps to Watch For

Commodity exclusions. High-value or theft-prone commodities are commonly excluded from standard cargo policies. Electronics, tobacco, alcohol, and pharmaceuticals all appear frequently on exclusion lists. A carrier who submits a cargo certificate showing $500,000 in coverage may have zero coverage for the specific freight type being shipped.

Theft by employee or driver. Some policies exclude theft committed by the carrier's own employees or drivers, which is precisely how a significant portion of cargo theft occurs.

Coverage gap during layover or storage. Standard motor truck cargo policies cover freight in transit. Extended layovers, drop-and-hook arrangements, or temporary warehouse storage may fall outside the coverage period.

Single-occurrence limits vs. per-trailer limits. A carrier with two trailers and a $100,000 limit per occurrence - not per trailer - has a combined maximum exposure on both loads of $100,000, not $200,000. High-volume shippers need to understand the per-occurrence structure.

Common Compliance Mistakes

Accepting an ACORD 25 that lists auto liability only. Auto liability does not cover cargo. If cargo coverage is not separately confirmed on the certificate, the requirement is not verified.

Not checking commodity exclusions. The certificate may show an adequate limit for the cargo requirement, but the exclusions embedded in the policy may eliminate coverage for the specific freight being tendered.

Overlooking cancellation notification requirements. Many broker-carrier agreements require 30-day prior notice of cancellation. If the certificate does not reflect this, the broker may have no warning before coverage lapses.

How Bramble Helps

Bramble reads broker-carrier agreements and shipper contracts to identify cargo insurance requirements - limit amounts, commodity-specific requirements, and certificate notification terms - then verifies submitted certificates for compliance. With 70% of COIs non-compliant at first submission in transportation as in other industries, automated review prevents non-compliant carriers from slipping through.
