A dump truck, known also as a dumper truck or tipper truck, is used for taking dumps (such as sand, gravel, or demolition waste) for construction as well as coal. A typical dump truck is equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited ("dumped") on the ground behind the truck at the site of delivery. In the UK, Australia and India the term applies to off-road construction plant only, and the road vehicle is known as a tipper lorry (UK, India), tip-truck, tip-trailer, tipper truck, or tipper (Australia and New Zealand).

A standard dump truck is a truck chassis with a dump body mounted to the frame. The bed is raised by a vertical hydraulic ram mounted under the front of the body, or a horizontal hydraulic ram and lever arrangement between the frame rails and the back of the bed is hinged at the back of the truck. The tailgate can be configured to swing up on top hinges (and sometimes also to fold down on lower hinges) or it can be configured in the "High Lift Tailgate" format wherein pneumatic rams lift the gate open and up above the dump body.

In the United States most standard dump trucks have one front steering axle and one (4×2[a] 4-wheeler)) or two (6×4 6-wheeler) rear axles which typically have dual wheels on each side. Tandem rear axles are almost always powered,[b] front steering axles are also sometimes powered (4×4, 6×6). Unpowered axles are sometimes used to support extra weight.[c] Most unpowered rear axles can be raised off the ground to minimize wear when the truck is empty or lightly loaded, and are commonly called "lift axles".

European Union heavy trucks often have two steering axles. Dump truck configurations are two, three, and four axles. The four-axle eight wheeler has two steering axles at the front and two powered axles at the rear and is limited to 32 metric tons (35 short tons; 31 long tons) gross weight in most EU countries. The largest of the standard European dump trucks is commonly called a "centipede" and has seven axles. The front axle is the steering axle, the rear two axles are powered, and the remaining four are lift axles.

The shorter wheelbase of a standard dump truck often makes it more maneuverable than the higher capacity semi-trailer dump trucks.
