Lance Stroll has become the latest driver to receive a grid penalty for the United States Grand Prix after the stewards found him guilty of blocking Romain Grosjean in Q1.
The dawdling Canadian almost ran into Grosjean on the exit of Turn 19 with traffic building up ahead of the latest hot laps at the Circuit of the Americas.
Grosjean was forced onto the grass to avoid a collision with Stroll, who joins Kevin Magnussen on the naughty step as he too was given a three-place grid drop for impeding Sergio Perez.
An FIA statement read: “The stewards examined multiple angles of video evidence, including CCTV not available on the broadcast and radio calls to car 18, and heard from Lance Stroll, the driver of car 18, Romain Grosjean, the driver of car 8 and the team representatives.
“Stroll was on a slow lap, Grosjean on a fast lap. Stroll was changing settings under direction of his engineer and got a very late call about Grosjean overtaking.
“The stewards believe the team should have given Stroll more advance warning that Grosjean was approaching rapidly.”
Stroll, who was knocked out in Q1, also picked up his first penalty point on his licence.
Magnussen had a penalty point added to his licence after the stewards deemed he blocked Sergio Perez in Q1. He also received a three-place grid penalty.
Meanwhile, Max Verstappen, Stoffel Vandoorne, Nico Hulkenberg and Brendon Hartley all picked up engine penalties.
