Use of the Drag Reduction System (DRS) overtaking aid (which alters the angle of the rear wing flap to reduce drag) is strictly controlled.

Drivers are free to activate the DRS as they wish within the designated DRS zones during practice and qualifying, but during the race they may only activate it when they are within one second of the car in front (indicated to him via a dashboard light) at the DRS detection point.

The DRS is disabled (resetting the rear wing flap to its original position) the first time the driver uses the brakes after activation.

In race conditions the DRS is available for use after two laps, but the race director may choose to suspend its use in poor weather conditions or if there are yellow flags in the DRS activation zone.
