Formula 1 drivers have been warned that they risk having their lap times deleted if they exceed track limits through Parabolica at Monza.
The FIA has policed track limits at some corners this season through the use of timing loops that have been installed.
This has been done in order to reduce the reliance on aggressive kerbs that can damage cars and cause teams additional costs.
The run-off area at Parabolica – the long-radius right-hander that leads on to Monza’s main straight – has been contentious ever since tarmac replaced gravel in 2014.
In his pre-event notes Formula 1 Race Director Michael Masi has stressed that “a lap time achieved during any practice session or the race by leaving the track (all four wheels over the white track edge line) on the outside of Turn 11 [Parabolica], will result in that lap time and the immediately following lap time being invalidated by the stewards.”
As usual drivers have also been warned about the etiquette of running wide at the Rettifilo and Roggia chicanes.
“Four rows of polystyrene blocks have been placed in the escape road [at the first chicane],” read the notes.
“In order to ensure that cars are able to re-join the track safely any driver using the escape road must go around the end of each of these rows and re-join the track at the end of the escape road.
“Drivers may only use the grass if it is clearly unavoidable. A lap time achieved during any practice session or the race in this manner will result in that lap time will being invalidated by the stewards.
“Any driver going straight and who misses the black and yellow bumps placed before the apex kerb of Turn 5 must stay to the right of the yellow line and the bollard, he may then re-join the track at the far end of the asphalt run-off area after the exit of Turn 5.
“A lap time achieved during any practice session or the race in this manner will result in that lap time will being invalidated by the stewards.”
Drivers have also been told that they risk receiving the black and white flag if they transgress on three occasions and will be reported to the stewards thereafter.
Elsewhere at Monza the track has been resurfaced between the Rettifilo and Roggia chicanes at the start of the lap, while the two DRS zones – along the main straight and Serraglio straight – have been maintained.
