Lance Stroll has been given a five-place grid drop for the United States Grand Prix following his collision with Esteban Ocon in the sprint over 12th place.
The pair were battling just outside the top 10 late on when, on lap 16, Stroll made a late lunge down the inside under braking for Turn 1.
Having locked up as he approached the apex, he slid into the left rear corner of Ocon’s Haas – spinning his rival around and out on the spot.
The impact smashed up Stroll’s right front suspension and, although he briefly carried on, the Canadian pulled over to the side of the track a few corners later.
With Ocon’s Haas left stricken in the run off at Turn 1, the safety car was called which ultimately meant the sprint finished under caution conditions.
Having been summoned to see the race stewards over what happened, it was deemed that Stroll was totally to blame for the incident.
Stroll was handed a 10-second penalty for having caused a collision but, as he did not finish the race, it has been converted to a five place grid drop. This will be enforced immediately for Sunday's United States Grand Prix.
The stewards said Stroll "misjudged the braking point" which caused the collision with Ocon.
Stroll himself owned up to making an error.
"Yeah, just a misjudgement, a mistake," he said afterwards. "We had a bad start, but then we were making our way back through the field.
"I thought I was close enough to dive down the inside, but then the inside of the track was just a little bit dirty, so I locked the front left, and I was just too far behind to make the move. So, apologies to Esteban."
Ocon was philosophical about what happened afterwards, as he claimed that drivers are always less cautious in the sprint.
“We are all taking a lot of risks in those sprint races because the reward to move forward is still quite big, and you need to try and make the overtakes done,” he said.
“But unfortunately, wrong place, wrong time. It’s racing, some of these things happen but we need to aim and try and qualify better.”
