The pair tangled at the Rettifilio chicane on lap 26 of the race after the Mercedes driver came out of the pits slightly ahead of his rival. Verstappen attempted to pass Hamilton on the inside of the second part of the chicane, ran over the high kerb on the inside, and made contact with the Mercedes.
Verstappen’s car rode over the top of Hamilton’s Mercedes and ended up perched on top of it. His right-rear wheel passed alarmingly close to Hamilton’s crash helmet, damaging the roll hop and coming to a rest on the Halo.
“That’s what you get for not leaving me space,” exclaimed Verstappen before climbing out of his car. Hamilton’s camera was damaged in the collision and his response was not heard.
The stewards announced the collision will be investigated after the race.
The two championship contenders previously tangled at the British Grand Prix. Hamilton was given a 10-second time penalty for that collision, which put Verstappen out of the race.
