In corner 3 of the first lap, both Finnish drivers (Bottas and Räikkönen) collided, causing a puncture in Bottas's front right tyre. Vettel took advantage to seize second place, followed by Sergio Pérez and Max Verstappen. Bottas was forced to stop in the pits, falling one lap behind the leaders. Ricciardo pitted on lap 6 to remove debris from his brakes. He rejoined in 17th place. His teammate Verstappen had to retire due to an issue with his engine on lap 12. Hamilton led Vettel until the first safety car was deployed on the same lap to remove the stranded Toro Rosso of Daniil Kvyat. This safety car period allowed Bottas to unlap himself. On lap 17, racing resumed but another safety car was deployed almost immediately to clear more debris off the track, which came from Räikkönen's Ferrari. During both safety car periods, Hamilton repeatedly complained that the safety car was moving too slowly. On lap 19 whilst still under safety car conditions Vettel ran into the back of Hamilton, damaging his front wing and Hamilton's rear diffuser. He then drove alongside Hamilton and swerved into his car, to protest what he believed was Hamilton brake-testing him. However, TV replays and car data showed that Hamilton had not applied his brakes at any point during the first collision. The race stewards put the incident under investigation. Racing resumed on lap 20 with Felipe Massa moving up to third and pressurizing Vettel, but within a few corners, the Force Indias of Esteban Ocon and Sergio Pérez collided and left debris on the track. The collision gave Ocon a puncture and dropped him to the back of the field. Pérez lost his front wing, and suffered damage to the front left wishbone which forced him to retire after making his way to the pit lane. Räikkönen, who was following the two Force Indias closely, got a puncture as a result of debris from the crash, and after the broken tire caused damage to the floor of his car as well as his rear wing, he too was pushed to his garage to retire. A third safety car was then deployed almost immediately, and after Fernando Alonso complained over the radio about the amount of debris, the race was red-flagged on lap 22 so that marshals could clear the track. During the red-flag period, which lasted over 20 minutes, teams worked on
