History

Historical Context

On February 18 2001, Dale Earnhardt died from a basilar skull fracture on the final lap of the Daytona 500 at Daytona International Speedway. The tragedy, seen by millions, spurred NASCAR to mandate HANS head-and-neck restraints in October 2001, install SAFER barriers, and develop the Car of Tomorrow, reshaping safety across its three national series. He was 49.
