Short course off-road racing is a form of auto racing involving the racing of modified vehicles on a dirt road closed course of a short length. It is distinct from long course desert racing such as the Baja 1000, which consists of racing at least hundreds of kilometers / miles over a quasi linear (non-closed) course from one point to another.

Auto racing is a motorsport involving the racing of automobiles for competition. In North America, the term is commonly used to describe all forms of automobile sport including non-racing disciplines.
