A HANS device (Head and Neck Support device) is a type of head restraint, a safety device in motorsports. Head restraints are mandatory when competing with most major motorsports sanctioning bodies. They reduce the likelihood of head or neck injuries, including the often fatal basilar skull fracture, in the event of a crash. There are many such devices on the market today, but the HANS is the original and the most common.
Even after Earnhardt’s death, use of the HANS device or similar products was resisted. The following weekend, Mark Martin said at Rockingham, “I would not wear one for anything. I’ll just keep my fingers crossed and take my chances”. Following an extensive investigation into Earnhardt’s death that ended in August 2001, NASCAR did not make any immediate changes regarding use of HANS. Then on October 4, 2001, in an Automobile Racing Club of America (ARCA) race being held in conjunction with the fall NASCAR racing weekend at the Charlotte Motor Speedway, Blaise Alexander was killed in a two-car incident while battling for the lead in the final laps of the race. Coincidentally, the other driver racing for Alexander for the lead was Dale Earnhardt’s oldest son Kerry Earnhardt. The younger Earnhardt’s car flipped on its roof after Alexander went into the wall, but he was in the lead when the race was halted with four laps to go. Due to carnage of the accident, the race was never restarted, so Earnhardt was declared the winner. NASCAR mandated use of the HANS device in its top three series on October 17, 2001.
