An off-road vehicle is considered to be any type of vehicle which is capable of driving off any paved or gravel surface. It is generally characterized by its highly tread tires and internal space, as these factors enable the vehicle to drive off smoother surfaces.

Off-road vehicles may be praised by extremists because of the many uses off-road vehicles have and their being versatile. Modern sports may involve the racing of off-road vehicles through natural environments off roads or designated driving areas.

This encourages growth in human interest, but it also defers much of the environment being affected by the events. As humans expand into off-road territory, it generally means that they are moving into the habitat of many other species. Because of pollution caused by all automobiles, the habitats are destroyed. Not only does the natural air leave as the humans and vehicles deposit carbon into the atmosphere but also often oil remains because of intense vehicle use. In addition, the organisms that are being tread on by the tires of the off-road vehicles are also intensely hurt.

Common Off-road vehicles are:

• Hummers
• Jeeps
• Land Rovers
• Large 4x4 trucks and SUV's

Less common Off-road vehicles are:

• Pinzgauers
