Earnhardt died at 49 from injuries incurred during a last-lap accident in the 2001 Daytona 500.

His death led to safety advancements in cars and equipment that have helped prevent any losses of life from occuring in the NASCAR Cup Series in the years since.

Known to fans and foes alike as The Intimidator, the Kannapolis, N.C., native raced through 27 years in the top series, racking up 76 wins and a record-tying seven season championships, which all took place before the knockout playoff-type format was put in place.

His son, Dale Jr., marked the occasion by retweeting a previous tribute where he called his father "the biggest badass whoever drove a racecar."
