As Charlotte Motor Speedway celebrates 50 years of racing, fans will determine the greatest racing moment in the speedway's history by logging onto to vote for their favorite Charlotte Motor Speedway memory.

The top moments in Charlotte Motor Speedway history have been narrowed down to 32 and condensed into short video clips that fans can view prior to making their choice. The online selection process pairs those memorable video clips in a bracket-style voting system with new video matchups revealed each week. The moment that receives the most votes in each bracket pairing will advance to the next round until only the top vote-getter remains.

"For five decades Charlotte Motor Speedway has produced the most memorable moments in motorsports," said Marcus Smith, president and general manager of Charlotte Motor Speedway.

"The fans have helped us make history and it's only fitting that the fans choose the greatest on-track moment ever at LMS. I know they'll have some fun watching the brackets pair down different drivers and moments against each other from different eras."

The greatest racing moment in Charlotte Motor Speedway history as selected by the fans will be announced during the week leading up to the 25th running of the NASCAR Sprint All-Star Race on May 16.
