Are the teams allowed to change drivers during the season?
Yes, each team with two cars may change the driver of its first car once in the season. For the second car, a maximum of three drivers may take turns, without restriction, during any one season. This excludes cases of force majeure, which are not counted. Notification of a change of driver must be made before the end of the scrutineering and the sporting checks (the Thursday preceding the event, at 18.00).
