Formula 1 drivers have been warned that the FIA is adopting a 'zero tolerance' approach to track limits at Copse Corner over the remainder of the British Grand Prix weekend.
The high-speed corner, which used to be the first turn, features a wide run-off area and drivers can gain an advantage by drifting out wide across the kerbs.
But following discussions in the drivers' briefing at Silverstone on Friday night, F1 race director Charlie Whiting said abuse of the track limits there would not be allowed.
In a note sent to teams on Saturday morning, he said: "We will be adopting a 'zero tolerance' approach to cars leaving the track on the exit of turn 9 during qualifying.
"Unless we are satisfied that a driver left the track at this point for reasons beyond his control, having been forced off the track for example, every lap time achieved by leaving the track will be deleted."
Whiting added: "During the race, any driver who appears to have gained a clear and lasting advantage by leaving the track at turn 9, or who repeatedly leaves the track at this corner, will be reported to the stewards."
Motorsport.com understands that there were also discussions about track limits at the final corner of the new track, but Whiting was happy that anyone drifting wide here would not gain an advantage.
