carrier

n. in general, any person or business which transports property or people by any means of conveyance (truck, auto, taxi, bus, airplane, railroad, ship), almost always for a charge. The carrier is the transportation system and not the owner or operator of the system. There are two types of carriers: common carrier (in the regular business or a public utility of transportation) and a private carrier (a party not in the business, but agrees to make a delivery or carry a passenger in a specific instance). Regular transportation systems are regulated by states and by the Interstate Commerce Commission if they cross state lines. (See: common carrier, private carrier)
