An all-terrain vehicle (ATV), also known as a quad, quad bike, three-wheeler, or four-wheeler, is defined by the American National Standards Institute (ANSI) as a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. Although it is a street-legal vehicle in some countries, it is not street legal within most states and provinces of Australia, the United States, Canada, or the United Kingdom. In the UK, a recent variant class of ATV is now road-legal, but there are few models available in this class.
By the current ANSI definition, ATVs are intended for use by a single operator, although some companies have developed ATVs intended for use by the operator and one passenger. These ATVs are referred to as tandem ATVs.
The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although equipped with three (or typically, four) wheels, six-wheel models exist for specialized applications. Engine sizes of ATVs currently for sale in the United States, , range from 49 to 1,000 cc (3 to 61 cu in).

騎車人坐在操作這些車輛和摩托車一樣，但額外的車輪在較慢的速度提供更多的穩定性。雖然配備有三個（或通常情況下，4）輪轂，六輪模型存在專門的應用程序。發動機尺寸的全地形車目前在美國銷售，範圍從49到1000毫升（3至61立方米）。
