What freight and freight truck companies are
In shipping, freight means commercial goods moved in bulk, on pallets or as equipment, as opposed to small parcels or personal belongings.
A freight truck company moves that freight by road, or arranges the move with a licensed carrier. Manufacturers use one for parts and materials, distributors for stock, retailers for store restocks and contractors for equipment. Trucks carry most of the value of US freight, so the company you choose touches much of your supply chain.
