| Abstract from DBPedia | An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike, or simply a quad, as defined by the American National Standards Institute (ANSI); is 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, territories and provinces of Australia, the United States or Canada. 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 most are equipped with three or four wheels, six-wheel models exists and existed historically for specialized applications. Multiple-user analogues with side-by-side seating are called utility terrain vehicles (UTVs) or side-by-sides to distinguish the classes of vehicle. Both classes tend to have similar powertrain parts. Engine sizes of ATVs currently for sale in the United States (as of 2008 products) range from 49 to 1,000 cc (3.0 to 61 cu in).全地形対応車（ぜんちけいたいおうしゃ、英: All Terrain Vehicle、略：ATV、仏: Véhicule Tout-Terrain、略：VTT）は、低圧タイヤを用いて不整地を含む様々な地形を進むことのできる原動機付きの車両である。 米国規格協会（ANSI）の定義によると、全幅50インチ以下、重量600ポンド以下で、低圧タイヤを装着し、跨座式シートと棒形ハンドルで操縦される車両とされている。日本ではバギー、四輪バギー、日本国外ではクアッド、クアッドバイクとも称されている。 二人乗り・四人乗りの場合はサイド・バイ・サイド・ビークル（S×S）に分類される。 (Source: http://dbpedia.org/resource/All-terrain_vehicle) |
