 Jenson Button, Adrian Sutil, Nico Rosberg, Scott Speed and Vitantonio Liuzzi did not take the restart as they all aquaplaned off the track at turn one on lap three, causing the red flag.The race restarted under safety car conditions, with an agreement that after one and a half minutes, any lapped cars would be allowed to overtake all the cars in front (including the safety car) and unlap themselves.The only lapped car was that of Lewis Hamilton, who unlapped himself and then pitted to change to dry tyres, a gamble which did not pay off due to the track still being too wet.
