Formula 1 drivers have been warned that their lap times will be deleted should they exceed track limits through Turn 11 at the Autodromo Hermanos Rodriguez.
The Turn 11 left-hand kink is the last part of the Esses section, of which much of the second sector is composed at the Mexican Grand Prix.
In his revised event notes F1 Race Director Charlie Whiting outlined the instructions to drivers, taking a similar stance to how the Circuit of the America’s Turn 19 was dealt with last weekend.
“If a driver crosses the kerb on the exit of Turn 11 during qualifying and, as a result, no part of the car remains in contact with the red and white section of the kerb, the lap time of the driver concerned will be deleted by the stewards,” read Whiting’s notes.
“During the race a black and white flag will be shown to any driver who clears the red and white section of the kerb three times, any further occurrence will then be reported to the stewards.
“Each time any car clears the red and white section teams will be informed via the official messaging system.”
Red Bull’s Max Verstappen led the way through both of Friday’s practice sessions.
