Several drivers have been dealt grid penalties for today's GP2 feature race in Istanbul following a string of indiscretions during yesterday morning's practice session.
The most severe punishment was reserved for Racing Engineering's Dani Clos, who was dealt a 10-place penalty for ignoring the instructions from marshals after his car stopped on the side of the track, prompting a long yellow flag period. With the Spaniard having qualified 22nd, the penalty moves him to the back of the grid.
Three-place grid penalties were given to three other drivers for failing to observe yellow flags, meaning that iSport pair Giedo van der Garde and Diego Nunes will now start from 14th and 21st respectively, and Edoardo Mortara will drop to 17th.
Romain Grosjean also faced the stewards for ignoring yellows but escaped with a reprimand.
