Formula 1 drivers' use of movable wings will be reformed for 2011, after today's FIA World Motor Sport Council approved the team's proposals for a new regulation aimed at increasing overtaking next season.
F1 is set to introduce an adjustable rear wing next season, in place of the current adjustable front wing and F-duct, and any device in 2011 will only be able to be activated to assist in passing other cars. The bodywork will not be allowed to be moved during the first two laps of a race, and thereafter only when a driver is less than one second behind the car in front.
A statement from the World Motor Sport Council said: "From 2011, adjustable bodywork may be activated by the driver at any time prior to the start of the race and, for the sole purpose of improving overtaking opportunities during the race, after the driver has completed two laps.
"The driver may only activate the adjustable bodywork in the race when he has been notified via the control electronics that it is enabled. It will only be enabled if the driver is less than one second behind another at any of the pre-determined positions around each circuit. The system will be disabled the first time the driver uses the brakes after the system has been activated.
"The FIA may, after consulting all the competitors, adjust the time proximity in order to ensure the purpose of the adjustable bodywork is met."
The FIA also announced that F-ducts will be banned next year. "With the exception of the parts necessary for the driver adjustable bodywork, any car system, device or procedure which uses driver movement as a means of altering the aerodynamic characteristics of the car is prohibited from 2011," the statement said.
The safety car rules have also been tweaked next season to confirm that drivers cannot overtake if the safety car enters the pit lane at the end of the final lap of a race, in reaction to Michael Schumacher's move on Fernando Alonso at Monaco.
