A side-by-side vehicle (SxS or SSV), is an off-road vehicle with a minimum of two seats positioned side by side and enclosed within a roll cage structure. They have a minimum of four wheels (or continuous tracks) and are operated by foot controls and a steering wheel. Depending on use and application they can also be called a utility task vehicle, utility terrain vehicle (UTV), recreational off-highway vehicle (ROV), or multipurpose off-highway utility vehicle (MOHUV).[1][2][3][4][5]
Side-by-sides may be included in the category of all-terrain vehicles (ATVs),[6] but do not include vehicles with saddle-seats that are operated using handlebar-type controls that are the conventional meaning of that term.
