A truck (United States, Canada, Australia, New Zealand, Puerto Rico and Pakistan; also called a lorry in the United Kingdom, Ireland, South Africa, and India) is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power, and configuration, with the smallest being mechanically similar to and larger than an automobile. Commercial trucks can be very large and powerful, and may be configured to mount specialized equipment, such as in the case of fire trucks and concrete mixers and suction excavators.
