The FIA has confirmed that it will use an electronic system to enforce track limits at the Autódromo Hermanos Rodríguez's Turn 11 during this weekend's Mexican Grand Prix.
The FIA have previously used such a system at the Belgian GP to monitor the Raidillon corner, which alerts the stewards when a driver crosses the white line with all four wheels.
Mexico's Turn 11 is another high speed corner where running wide can provide a time advantage and the stewards are therefore keen to monitor the situation, warning drivers that their times will be deleted and they could face a penalty for repeated offences.
"A lap time achieved during any practice session or the race by a driver completely crossing the red and white kerb on the exit of Turn 11 with no part of the car remaining in contact with the red and white section of the kerb, will be invalidated by the stewards," explained FIA race director Michael Masi.
"On the third occasion of a driver completely crossing the red and white kerb on the exit of Turn 11 with no part of the car remaining in contact with the red and white section of the kerb during the race, he will be shown a black and white flag, any further cutting will then be reported to the stewards.
"Each time any car completely crosses the red and white kerb on the exit of Turn 11, teams will be informed via the official messaging system.
"The above requirements will not automatically apply to any driver who is judged to have been forced off the track, each such case will be judged individually."
Masi also made clear that a number of corners will have penalty bollards which must be navigated before a driver rejoins the track if they miss or cut the corner. These include Turns 1, 2, 3, 8 and 11.
