An off- road vehicle is considered to be any type of vehicle which is capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension, or even caterpillar tracks. Other vehicles that do not travel public streets or highways are generally termed off- highway vehicles, including tractors, forklifts, cranes, backhoes, bulldozers, and golf carts.
Off- road vehicles have an enthusiastic following because of their many uses and versatility. Several types of motorsports involve racing off- road vehicles. The three largest "4- wheel vehicle " off- road types of competitions are rally, desert racing, and rockcrawling. The three largest types of all- terrain vehicle (ATV) / motorcycle competitions are Motocross, Enduro, and also desert racing like Dakar Rallye and Baja 1000. The most common use of these vehicles is for sight seeing in areas distant from pavement. The use of higher clearance and higher traction vehicles enables access on trails and forest roads that have rough and low traction surfaces.
