Knight-Swift Transportation is the largest full-truckload carrier in the US, with a diversified transportation offering. Roughly 82% of revenue derives from Knight’s asset-based trucking business, with full truckload (for-hire dry van, refrigerated, and dedicated contract) making up 63% and less than truckload 19%. Truck brokerage and other asset-light logistics services make up 8% of revenue, with intermodal near 5%. Knight's intermodal operations use the Class I railroads for the underlying movement of its shipping containers and include drayage (regional trucking services to and from inland intermodal ramps/terminals). The remainder of revenue is from services offered to shippers and third-party truckers, including equipment maintenance and leasing.
