British amateur driver Marcus Mahy is conscious in the wake of the accident that caused the Spa 24 Hours to be red-flagged shortly before one-third distance.
The Kessel Ferrari driver has been woken from a medically-induced coma, is reacting to stimulation and can move all of his limbs.
The 53-year-old will remain in the CHU hospital in Liege for an undisclosed period and is expected to undergo surgery on his neck in the coming days.
Mahy was airlifted to hospital after an incident on the exit of Stavelot Corner involving the Rinaldi Ferrari driven by Vadim Kogay.
The race had to be halted for the medical helicopter to land on the track.
