While an ATV and a UTV will share many similarities, they are distinctly different vehicles intended for very different uses. An ATV, or all terrain vehicle, is an off-road, single-rider vehicle intended for use as a recreational vehicle, racer, or transport over rough terrain. A UTV, or utility task vehicle, is also intended for use over rough terrain, though this vehicle is sometimes known as a side-by-side because two people can sit in the cab next to each other. Both can be used to haul items, but a UTV features a truck-like bed specifically for this purpose.
