Lasting legacy: Earnhardt's death saved lives, forced change

NASCAR mandated the use of head-and-neck restraints in late 2001. Drivers had resisted using the U-shaped neck restraint made of carbon fiber because they found it cumbersome and restrictive. They became required equipment after 25-year-old Blaise Alexander was killed in a crash at Charlotte Motor Speedway some eight months after Earnhardt's death.(AP Photo/Chris O'Meara, File)

Childress, now 75, often wonders what NASCAR would look like had Earnhardt survived. Childress was far more than Earnhardt's car owner. The two were hunting and fishing buddies, business associates and close friends. (AP Photo/Harold Hinson, File)

On the cusp of a national popularity explosion, NASCAR never stopped after the deaths of Adam Petty, Kenny Irwin Jr. and Tony Roper. But losing Earnhardt forced the stock car series to confront safety issues it had been slow to even acknowledge, let alone address. The dramatic upgrades have saved multiple lives — NASCAR has not suffered a racing death in its three national series since — and are the hallmark of Earnhardt's legacy.

NASCAR fans and fellow competitors feared the worst for Newman, but the 2008 Daytona 500 winner walked out of the hospital 48 hours later holding hands with his girls. He is a symbol of how far the sport has come since NASCAR's darkest day 20 years ago, when seven-time champion Dale Earnhardt was killed in the final turn of the 500. (AP Photo/Chris O'Meara, File)
