All terrain vehicles are usually referred to as ATVs. They are also called quads, quad bikes, three-wheelers, and four-wheelers. Some are for recreation, others for utility purposes. There are two basic types. Type I is for the operator only. Type II is for the operator and 1 passenger. They are designed for off the road use only. The seat of ATVs are similar to a motorcycle seat. It has to be straddled by the vehicle operator. Another similarity to a motorcycle are the handle bars for steering. They are designed to be driven, or operated, on rugged territory unsuitable for automobiles.

Utility vehicles ATV or all-terrain vehicles, are popular motor-driven, off-highway automobiles. They are made with handlebars and a seat just like a motorbike but with 4 tires which are there for control in addition to safety when riding along unpaved streets. The term is much more generally used to explain a number of small, open, motorized buggies and that are intended for off road driving.
