A truck driver (commonly referred to as a trucker or driver in the United States and Canada; a truckie or ute driver in Australia and New Zealand; a lorry driver or driver in Ireland and the United Kingdom), is a person who earns a living as the driver of a truck, usually a semi truck, box truck, or dump truck.

Truck drivers provide an essential service to industrialized societies by transporting finished goods and raw materials over land, typically to and from manufacturing plants, retail and distribution centers. Truck drivers are also responsible for inspecting their vehicles for mechanical items or issues relating to safe operation. Others, such as Driver/Sales workers, are also responsible for sales and customer service.
