A dune buggy is a recreational vehicle with large wheels, and wide tires, designed for use on sand dunes, beaches, or desert recreation. It is called a "Beach Buggy" in the United Kingdom, Ireland and many other English speaking countries. The design is usually a modified vehicle and engine mounted on an open chassis. The modifications usually attempt to increase the power-to-weight ratio by either lightening the vehicle or increasing engine power or both. Dune buggies designed specifically for operation on open sand are called sandrails.
A similar, more recent generation of off-road vehicle, often similar in appearance to a sandrail but designed for different use, is the "off road go-kart". The difference may be little more than fitting all-terrain tires instead of sand tires and the much smaller size of the engine.

A sandrail, or sand rail, or rail, is a lightweight off-road motor vehicle specifically built for traveling in sandy terrain. Similar in some respects but often mistakenly referred to as a dune buggy or sand car, a sandrail is a different type of specialty vehicle. Sandrails are popularly operated on actual sand dunes. Some of the most popular sand dunes in the United States include; Dumont Dunes CA, Coral Pink UT, Oregon Dunes OR, St. Anthony Dunes ID and the grand daddy of dune riding Algodones Dunes CA (Imperial Sand Dunes). Sandrails can be driven on other types of terrain but are truly designed specifically for the sand.
