Lewis Hamilton and Nico Rosberg will lose ten places on the grid at the French Grand Prix following their pitlane incident in Canada.
Hamilton crashed into the back of Ferrari's Kimi Raikkonen at the end of the pitlane on lap 20, when the Finn braked to stop in front of the red light. The Briton said he saw the light too late and could not avoid hitting the Ferrari.
Both men retired in the accident.
Rosberg could not stop in time either and hit Hamilton from behind, although the Williams driver was able to continue in the race.
Both Hamilton and Rosberg will be hit with a 10-place grid penalty in France in two weeks' time.
