A special stage (SS) is a section of closed road at a stage rallying event. Competitors attempt to complete the stage in the shortest time. A rally on a special stage is coordinated such that each competing car begins after a set interval, to reduce the chance of impedance by other competitors. Each special stage is a relatively short section, usually up to about 10 miles in length. A rally usually comprises approximately 10–15 special stages. The driver with the lowest overall time for all special stages in an event is the winner.
