Afterwards, NASCAR took numerous safety measures to ensure nothing like this would happen again, including making the HANS device mandatory during races. A police investigation ensued after his death, with allegations that the seatbelt device failed. Kevin Harvick replaced Earnhardt in his upcoming races for the year.
Earnhardt's death is considered one of the biggest and most tragic catastrophe's in NASCAR history, and his death left a mark on NASCAR, as well as being a media hype. His fans still remember him and celebrate his career.
Earnhardt would never wear a Hans device, stating throughout his career that he felt like it restricted him and was uncomfortable. This would ultimately become the biggest mistake of his career, and his life. Had he wore the Hans device, which is a mechanism that secures the head and neck from moving too much or too fast during a major hit, he may still be alive today. Even though nothing ever came of the allegations of seatbelt failure, several people from the seatbelt company resigned.
