Still felt heavily throughout the NASCAR community, the death of Dale Earnhardt occurred on February 18th, 2001 during the Daytona 500 in the 4th turn of the Daytona International Speedway. The race was on its final lap when Sterling Marlin connected with Earnhardt, sending him straight into a wall. Earnhardt’s estimated speed at the time of impact was between 155 to 160 miles or 249 to 257 kilometers per hour. At the Halifax Medical Center, the driver was pronounced dead after sustaining blunt force trauma to his head and a basilar skull fracture. In the wake of his death, investigations led to advanced safety improvements and mandated regulations, such as requiring the use of the head and neck support device, which Earnhardt had refused to wear.
