A truck stop is a commercial facility that provides fuel, parking, and often food and other services to long-haul trucks. Truck stops are usually located on or near a busy road and consist of a diesel grade fueling station with bays wide and tall enough for modern tractor/trailer rigs, plus a large enough parking area to accommodate from five to over a hundred trucks and other heavy vehicles.

The truck stop originated in the United States in the 1940s, as a reliable source of diesel fuel not commonly available at filling stations. This, coupled with the growth of the Interstate Highway System, led to the creation of the professional haulage and truck stop industries.
