Track limits over the remainder of the Qatar Grand Prix Formula 1 weekend will be policed by a single kerb rule after the FIA scrapped its original multi-corner instructions.
In opening practice track limits were policed specifically at Turns 4, 12, 13, 14 and 16.
At these corners going all four wheels beyond the white line resulted in a lap time being deleted and in the race it was meant to count as one of three strikes before a fourth offence earned a referral to the stewards.
However, during the session a radio message from FIA race director Michael Masi indicated that the system would be reviewed based on what was observed in FP1.
Ahead of second practice a revised set of event notes were distributed with a major change in the track limits section.
All of the original instructions have been struck off, and replaced by a single entry.
Now, the track limit on the exit of each corner at the Losail track “is defined as when no part of a car remains in contact with the purple and white kerb”.
“For the avoidance of doubt, drivers will be judged to have left the track on the exit of a corner if no part of the car remains in contact with the purple and white kerb,” Masi has written.
