Knight Transportation drivers don't drive long hours into the night. The truckload carrier instead focuses on short- to medium-haul trips, averaging about 500 miles. From some 35 regional operations centers, mainly in the southern, midwestern, and western US, Knight carries such cargo as consumer goods, food and beverages, and paper products. It has a fleet of more than 4,100 tractors and 9,700 trailers, including nearly 900 refrigerated trailers. Besides for-hire hauling, Knight provides dedicated contract carriage, in which drivers and equipment are assigned to a customer long-term. It also offers freight brokerage services.
