A lorry is a large vehicle that is used to transport goods by road. The definition of a lorry is a motor vehicle that is used to transport cargo. An example of a lorry is a truck in which goods are moved.
Trucks vary greatly in size, power, and configuration; smaller varieties may be mechanically similar to some automobiles. 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.
Modern trucks are largely powered by diesel engines, although small to medium size trucks with gasoline engines exist in the US, Canada, and Mexico. In the European Union, vehicles with a gross combination mass of up to 3.5 t (7,700 lb) are known as light commercial vehicles, and those over as large goods vehicles.
Almost all trucks share a common construction: they are made of a chassis, a cab, an area for placing cargo or equipment, axles, suspension and roadwheels, an engine and a drivetrain. Pneumatic, hydraulic, water, and electrical systems may also be present.
The cab is an enclosed space where the driver is seated. A “sleeper” is a compartment attached to or integral with the cab where the driver can rest while not driving, sometimes seen in semi-trailer trucks.
