Daniil Kvyat and Marcus Ericsson will both take grid drops ahead of next weekend’s Canadian Grand Prix after incidents in Monaco on Sunday.
Kvyat collided with Kevin Magnussen at La Rascasse while trying to unlap himself, having suffered an electrical problem in the early part of the race.
The incident ultimately caused Kvyat to retire and harmed Magnussen’s race, much to the frustration of the Renault driver.
“Kvyat just lost his mind and crashed into me and that was effectively the end of my race,” Magnussen said after also retiring.
“We did continue and made an early change to slicks as we had nothing to lose, but ultimately I hit the wall and damaged the front wing.”
While Kvyat put it down as a racing incident, the stewards looked dimly on the clash and handed the Russian a three-place grid drop for the Canadian Grand Prix on June 12.
The same penalty has been given to Ericsson, who crashed into Sauber teammate Felipe Nasr at the same corner amid a row over team orders.
Sauber team boss Monisha Kaltenborn called the behavior of both drivers “unacceptable”, but the stewards deemed Ericsson to be responsible, leaving him with the three-place grid drop.
Both Valtteri Bottas and Pascal Wehrlein were also penalized following the race in Monaco, both receiving points on their FIA super licence.
Wehrlein went too quickly under the Virtual Safety Car and ignored blue flags during the race, resulting in 20 seconds worth of time penalties and four penalty points on his licence.
Finally, Bottas crashed into Esteban Gutierrez at La Rascasse on the final lap of the race when trying to pass for 11th position, resulting in a 10 second penalty and two points against him.
