MONTREAL -- Lando Norris drove into the back of McLaren teammate and title rival Oscar Piastri four laps from the finish of the Canadian Grand Prix.
Norris, who was in fifth, was going for a tight pass on his teammate down the start-finish straight when he clipped the back of his car into the wall, destroying his front wing and left tyre.
The crash put Norris out of the race, which was won by pole-sitter George Russell, and ended under safety car.
"Sorry," Norris said on the radio immediately afterwards. "All my bad. All my fault. Stupid from me."
Norris told reporters after the race, he made "a fool of himself" and shouldn't have attempted the risky overtake.
"I should never have gone for it, it's my complete hindsight thing," a downbeat Norris said. "I thought he was starting to drift a little bit to the right, so there was an opportunity to go the left.
"Way too much risk, especially on my teammate. Happy nothing happened to him, and I paid the price for my mistake."
Norris later received a five-second time penalty from stewards for casuing the collision, but did not receive any penalty points.
The incident was the first on-track collision between the two frontrunners in the championship battle.
Piastri led Norris by 10 points in the championship ahead of the race. The gap has now widened to 22 points.
