International Sporting Code

The International Sporting Code (ISC) is a set of rules applicable to all four-wheel motorsport as governed by the Fédération Internationale de l'Automobile (FIA). It was first implemented in 1926.

The ISC consists of 20 articles and several appendices. It contains definitions, general principles, and regulations, as well as rules for race organisers, contenders, racers, and officials. As motorsport is very hierarchic, the ISC may also be applicable in the rules of national racing federations.

Some North American domestic racing, such as NASCAR and IndyCar are outside the FIA's jurisdiction and hence not governed by the ISC and they instead usually govern their own series themselves. Motorcycle sport is also exempt since the Fédération Internationale de Motocyclisme (FIM) is responsible for this sport, not the FIA.
