Stroll also hit with grid penalty for blocking
22 October 2017 – Lance Stroll has also been given a grid penalty of three places for the United States Grand Prix after blocking Romain Grosjean during qualifying.
Haas driver Grosjean – on a fast lap – approached Williams rookie Stroll – on a slow lap – at the exit of the penultimate corner in the Q1 phase at the Circuit of the Americas.
Stroll, having just been overtaken by Daniil Kvyat on the inside, darted right to get out of Grosjean's way, after a late call from his engineer, but the Frenchman was forced to take to the run-off.
Stewards deemed that, despite doing "what he could in the circumstances", Stroll was deserving of a three-place drop, and his first penalty point in Formula 1.
Stroll dropped out in Q1 in 17th after suffering a deployment issue on his final run, while Grosjean went on to reach Q2 and qualify 14th.
"The stewards examined multiple angles of video evidence, including CCTV not available on the broadcast, and radio to car 18, and heard from Lance Stroll, the driver of car 18, Romain Grosjean, the driver of car 8, and team representatives," read a statement from the stewards.
"Stroll was on a slow lap, Grosjean was on a fast lap. Stroll was changing settings under direction of his engineer and got a very late call about Grosjean overtaking.
"Stroll immediately moved right and off the track, but Grosjean was already outside track limits and made the decision to overtake on the right, as Stroll moved right.
"It was obvious Stroll was not able to see Grosjean approaching in his mirrors, and he stated he could not move to the left as Kvyat was passing him on that side.
"The stewards believe Stroll did what he could in the circumstances but nevertheless this was potentially a very dangerous situation as the speed differential between the two cars was in excess of 100 km/h at the apex of Turn 19.
"The stewards believe the team should have given Stroll more advance warning that Grosjean was approaching rapidly."
Kevin Magnussen was also penalised for impeding Sergio Pérez during qualifying.
