Chinese driver Guanyu Zhou said Formula One's halo head protection system saved him after his crushed car was wedged sideways between a tire wall and a metal fence at the British Grand Prix on Sunday.
The race was halted after the multi-car collision on the opening lap.
"I'm OK, all clear," Zhou said on Twitter after a trip to the medical center. "Halo saved me today. Thanks everyone for your kind messages."
