Stock car racing is a popular activity. Although spectators are seldom injured, drivers at short asphalt tracks often sustain minor injuries. The neck and the knee are the most commonly injured areas. Rigid safety requirements are essential and help to prevent serious injuries. Severe injuries occur on an average of once a year, but no fatalities have been recorded at one short track that has been studied for a six-year period.
