Drivers have been warned that track limits at Yas Marina must be strictly adhered to.

In a note sent to all the teams ahead of this weekend's season finale, Race director, Charlie Whiting, wrote: "Any car which uses a part of the areas behind the apex of turns 6, 9 or 12, and which is suspected of gaining any sort of advantage from doing so, will be immediately reported to the Stewards."

He also warned that if they run wide whilst battling for position, drivers must not benefit in terms of extending their lead or drawing within DRS range.

"If two cars are close to each other entering turn 8 and, by cutting behind the apex of turn 9, the leading one re-joins 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," he added. "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.

"If two cars are close to each other entering turn 8 and, by cutting behind the apex of turn 9, the following one re-joins 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."

In the meantime, fans just hope to see such battles given the nature of the track.
