Nico Hulkenberg has been handed a reprimand for crossing the white pitlane entry line at the end of opening practice for the Mexican Grand Prix.
The Force India driver ended Friday morning's session 16th fastest after sitting out some of practice in the pits while work was done on his car.
However, after being reported for crossing the white line between the track and the pit entry later on, the race stewards elected to give him a reprimand.
It is Hulkenberg's second reprimand of the season, having been penalised for also crossing the pitlane entry line during final practice for the Austrian Grand Prix.
Any driver that receives three reprimands during a season will be given a 10-place grid penalty at the current or next event.
