Autocross is a form of motorsports that emphasizes safe competition and active participation. An autocross is a timed competition where drivers navigate one at a time through a defined course. Autocross differs from road racing or oval racing in that generally there is only one car on the track racing against the clock rather than other cars. As an entry level motorsport it provides a stepping stone for drivers looking to move into other more competitive and possibly expensive forms of motorsport including rally and circuit racing.
Autocross courses are typically 1200' to 3000 feet in length and tend to place more emphasis on car handling and driver skill rather than on sheer horsepower. Courses may be temporary and marked by traffic cones or be permanent tracks with approval by a motorsport body.
Events typically have many classes which allow almost any vehicle, from economy sedans to purpose-built vehicles, to compete. Due to the nature of a typical track, speeds can be slower in absolute terms when compared to other forms of motorsports, usually not exceeding highway speeds, but the activity level (measured in discrete turns per minute) can be higher than even Formula One due to the large number of elements packed into each course.
