Some of the strict track limits in place at the Autodromo Hermanos Rodriguez will be relaxed for the start of Sunday's Mexican Grand Prix.
Ahead of this weekend's event, drivers were warned about track limits at several corners, with Turns 1, 2 and 3 coming under the spotlight throughout practice.
Mercedes driver Lewis Hamilton and Alfa Romeo's Kimi Raikkonen both picked up reprimands after running straight on at Turn 1 and failing to stay to the left of the designated bollard at Turn 3 when rejoining the track.
While this stipulation will remain in place for the race, it will not apply at the start, or subsequent restarts, though drivers have been told to rejoin the track in a safe manner, and without gaining a lasting advantage, if they do go off.
"Any driver who leaves the track at Turn 1/2 will be required to ensure that they rejoin the track safely and do not gain a lasting advantage," read a note from FIA Race Director Michael Masi. "In practical terms, this will mean giving up any positions that were gained.
"The instruction to go around the bollard at Turn 3 in this circumstance only will not be a requirement."
Sunday's 71-lap Mexican GP will begin at 13:00 local time (19:00 UK time).
