Formula 1 drivers have been warned about not trying to gain any kind of advantage by cutting the chicanes at the Yas Marina track.
In a note sent to teams on Saturday, F1 race director Charlie Whiting made it clear that any driver who uses the run-off areas behind Turns 6, 9 or 12 and is believed to have gained an advantage will be immediately reported to the race stewards. Furthermore, Whiting clarified two other situations where stewards will be asked to investigate.
Whiting wrote: "If two cars are in close proximity entering Turn 8 and, by cutting behind the apex of Turn 9, the leading one rejoins the track with a greater lead over the following car he will be reported to the stewards as having gained an advantage by leaving the track. This will apply whether or not the advantage gained had any influence upon the operation of the DRS by the driver in the following car."
He added: "If two cars are in close proximity entering Turn 8 and, by cutting behind the apex of Turn 9, the following one rejoins the track within DRS detection distance of the leading car, that driver may not deploy his DRS in the following activation sector. Any driver seen to be using his DRS under these circumstances will be reported to the stewards as having gained an advantage by leaving the track."
Whiting also informed drivers that anyone who cuts across a run-off area "without a clear and justifiable reason" on a reconnaissance lap will be reported to the stewards.
