Sebastian Vettel, Kimi Raikkonen and Max Verstappen will all be investigated following a crash at the start of the Singapore GP which wiped out the front-row.
As the field barreled down to Turn 1 on the wet track, Vettel moved to the left to cover his position, but sandwiched Verstappen into a fast moving Raikkonen.
The Red Bull clipped the Ferrari which was pitched into the side of Vettel.
The German managed to keep going and make his through Turn 1, but eventually spun further down the road, while Raikkonen and Verstappen were out on the spot.
The incident, in which Fernando Alonso was collateral damage after a brilliant start, brought out the Safety Car.
The FIA stewards announced that the startline incident was under investigation, with a ruling expected after the race.
