A truck or lorry is a type of automobile designed to carry heavy loads, carry specialized payloads, or do other practical tasks. Most trucks feature body-on-frame construction with a cabin independent of the payload portion and vary greatly in terms of size, power, and configuration. Commercial trucks can be very large and powerful. They may be designed to be mounted with specialized equipment, as is the case with suction excavators, fire trucks, concrete mixers, and refuse trucks.
