The Daytona 500 is an annual American stock car race sanctioned by the National Association for Stock Car Auto Racing (NASCAR) and held every February at the Daytona International Speedway in Daytona Beach, Florida.^[1][2] It was first held in 1959 after NASCAR founder Bill France Sr. wanted to take the sanctioning body away from the Daytona Beach and Road Course and onto a permanent racing facility to allow NASCAR races to continue being held in Daytona Beach.^[3][4] The event is the premier and final race of the three-week Speedweeks series of races and has been the first points-paying round of the NASCAR Cup Series since 1982.^[2][3] It usually covers 200 laps over a total distance of 500 mi (800 km),^[1] but accidents and other incidents have meant that the race has been extended through the use of overtime rules on several occasions.^[5] Each winning driver is presented with a replica of the Harley J. Earl Trophy in Victory Lane,^[6] a large sum of money,^[2] a championship ring as well as a black leather jacket,^[7] and their car is put on display in race-winning condition in the Motorsports Hall of Fame of America museum adjacent to the track for 12 months until the following year's Daytona 500.^[8][9]
