Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body.  The "formula" in the name refers to a set of rules to which all participants and cars must conform.  The F1 world championship season consists of a series of races, known as Grands Prix, held usually on purpose-built circuits, and in a few cases on closed city streets.  Drivers are awarded points based on their position in each race, and the driver who accumulates the most points over each calendar year is crowned that year's World Champion.

The 1982 South African Grand Prix was a Formula One motor race held at Kyalami on 23 January 1982.  The prelude to the race was notable for a strike action by the Grand Prix Drivers' Association, led by Niki Lauda and Didier Pironi, in protest at the new superlicence conditions imposed by FISA, which would have tied the drivers to a single team for up to three years.  A late compromise was reached and the race went ahead.  The drivers were subsequently fined between US$5,000 and US$10,000 and handed suspended race bans; however, the FIA Court of Appeal later reduced the penalties and criticised FISA's handling of the dispute.
