Reefer Breakdown Coverage

Reefer breakdown coverage is an endorsement to a motor truck cargo insurance policy that responds when perishable freight is damaged because a refrigerated trailer's cooling unit stops maintaining the required temperature. A base cargo form typically excludes loss from mechanical breakdown, latent defect, or failure of the refrigeration equipment, so a carrier hauling produce, meat, dairy, or pharmaceuticals can suffer a total spoilage loss with no coverage unless the breakdown peril is bought back through this endorsement.

For a small trucking business, this coverage matters because a single reefer load can be worth far more than the trailer itself, and a compressor or thermostat failure on a long haul can ruin the entire shipment before the driver reaches the destination. Underwriters usually require that the unit be properly maintained and, critically, that a continuous temperature recorder is running; many policies also demand the reefer be serviced on a set schedule. Because spoilage overlaps with contamination risk, buyers hauling food should confirm how the breakdown grant interacts with food spoilage and contamination perils so there is no gap between the two.

A practical nuance is the maintenance and setting warranty. If an adjuster's download of the temperature log shows the unit was set incorrectly, was turned off to save fuel, or missed a required service interval, the claim can be denied even though breakdown coverage was purchased. Deductibles on reefer breakdown are also frequently higher than the base cargo deductible. Owner-operators should keep service receipts and continuous temperature data, and verify the sublimit is high enough to cover their most valuable load rather than an average one. Reading the specific exclusion language for spoilage and mechanical failure is the surest way to know exactly when the coverage will pay.
