TRANSPORTATION BROKERS CONTINGENT CARGO COVERAGE is designed to insure cargo while in the custody of the motor truck carrier with whom the insured transportation broker has entrusted it. Warehouse-to-warehouse coverage is included and applies when the motor truck carrier cannot pay the shipper for its cargo loss because its insurance was cancelled, the claim was denied, or the limits of insurance were inadequate. It usually warrants that a valid motor truck cargo policy be accessible to the transportation broker's office for any vehicle brokered by the insured.
