Stewards have issued Sergio Perez with an eight-place grid penalty for failing to react to yellow flags during qualifying for the Singapore Grand Prix.
The Force India driver was summoned to the stewards after qualifying where he was handed a five-place penalty for failing to slow during a yellow flag period at the end of Q2 after Romain Grosjean's crash.
To make matters worse the Mexican was then issued with a further three-place grid drop for overtaking Esteban Gutierrez under double waved yellows.
Having qualified in 10th position, Perez will be demoted to 18th on the grid following the penalties.
“The driver of car 11 failed to reduce his speed significantly and be prepared to change direction or stop as required under Art188.8.131.52(b) when double yellow flags were being waved at both Turns 9 and 10,” read a statement from the stewards.
“The Stewards took into consideration the fact that the driver had two corners in which to slow down significantly and failed to do so.
“Both of which were blind corners (including one where the accident had taken place and where the damaged car was still in the barriers), and where the driver would not have known if the track had a hazard wholly or partly blocking the track and/or marshals working on or beside the track.”
Meanwhile, Grosjean has also incurred a five-place grid drop after his Haas F1 squad confirmed a gearbox change following the Frenchman's high speed crash in Q2.
Grosjean will start Sunday's Singapore Grand Prix at the Marina Bay Circuit from 20th on the grid.
