The DRS zone is the section of the track where the drivers may have the opportunity to activate their Drag Reduction System and gain a speed advantage. 

To activate the DRS, the driver must be less than one second behind the car in front when crossing the DRS detection line.

The DRS Zone is on a long straight to give the driver a straight-line advantage, and it snaps closed instantly when the driver touches his brake, returning downforce and allowing the car to corner at high speed.
