Due to extremely heavy rain, multiple cars had crashed and were stopped on the side of the track. On lap 144 race leader Richards, whose Nissan was barely driveable due to an earlier crash, slid off the race track and came to rest behind another stopped car. He was overtaken by several cars including Ford driver Dick Johnson who became the new race leader. The race was stopped soon after on lap 145. Normally the race results would have been wound back to the last completed lap, lap 144, and made Johnson the winner. However, due to the large number of crashed and stopped cars the race was wound back an additional lap to allow more cars to place; this made Richards the race winner.
