An all-terrain vehicle with three wheels or more is known as an ATV. Other names for an ATV include a four-wheeler or a quad. A four-wheeled all-terrain vehicle ''ATV'' is known as a quad, and it may have either two-wheel drive or four-wheel drive. A quad that only has four-wheel drive or all-wheel drive is called an all-terrain vehicle ''ATV''. It's possible that what I just said came out as unclear, so allow me to elaborate on each phrase.
