Lewis Hamilton and Sergio Perez have both received three-place grid penalties for Sunday's Indian Grand Prix after setting their fastest times under waved yellow flags at the end of first practice.
According to a statement from the FIA, Hamilton was penalized for ignoring double waved yellow flags at Turn 16 while marshals were in close proximity to the track.
The waved yellows were for Pastor Maldonado's stationary Williams, which had stopped with an apparent engine problem and was being attended to by track officials at the time that Hamilton and Perez set their best session times. The penalty means that Hamilton can only hope to start from fourth position on the grid at best for the Indian Grand Prix.
Former Formula 1 driver Johnny Herbert is serving as one of the stewards of the meeting this weekend.
