Fellow driver David Purley, who witnessed Williamson's impact, almost immediately pulled his car over on the opposite side of the track, then ran across the live racetrack to assist him. Williamson was heard shouting to Purley to get him out of the car as Purley tried in vain to turn the car upright. There appeared to have been ample time to right the car and pull Williamson out, but as desperately as he tried, Purley was unable to do it by himself, and the marshals, who were not wearing flame retardant overalls, were unable to help due to the intense heat.
Race control assumed that it was Purley's car that had crashed and that the driver had escaped unharmed. Many drivers who saw Purley waving them down to stop later claimed that they assumed Purley to be trying to put a fire out from his own car, having safely exited it, and thus did not know that a second driver had been involved. As a result, the race continued at full pace while Purley desperately tried to save the life of Williamson.
