Williams Formula 1 driver Sergey Sirotkin has been penalised for his collision with Force India's Sergio Perez on the opening lap of the Azerbaijan Grand Prix.
The Russian hit Perez's VJM11 from behind under braking into the Turn 2 left-hander, leading the Mexican to then collide with Ferrari's Kimi Raikkonen and further damage his car.
Sirotkin would go on to retire further down the road in a three-way collision with Nico Hulkenberg and Fernando Alonso, and was assessed a three-place grid penalty by the FIA stewards, which he is set to serve in the Spanish Grand Prix.
The rookie also picked up the first two penalty points on his license.
"The driver of car 35 [Sirotkin] drove into the back of car 11 [Perez]," a stewards' statement read, adding that Sirotkin was "wholly to blame for the collision".
Perez was forced to make an early stop in the aftermath of the collision, but recovered to finish the race in third place.
Also receiving a penalty was Haas driver Kevin Magnussen, who was found the guilty party in a clash with the Toro Rosso of Pierre Gasly.
The pair were fighting for the final points-scoring position of 10th on the late-race safety car restart following the clash between Red Bull duo Max Verstappen and Daniel Ricciardo, but ended up dropping down the order.
Gasly completed the race in 12th, while Magnussen rounded out the finishers in 13th place.
"The driver of car 20 [Magnussen] moved unpredictably and unnecessarily to the left and collided with car 10 [Gasly], which was maintaining its direction," the stewards' explanation read.
The Dane was handed a 10-second penalty, which had no impact on his race result, but also received two penalty points on his license, adding up to a total of eight for the 12-month period - with 12 points needed to trigger a race ban.
