The 68th Indianapolis 500 was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday May 27, 1984. Rick Mears, who previously won in 1979, won his second Indy 500 driving for Penske. Contenders Tom Sneva and Mario Andretti dropped out of the race in the second half, leaving Mears alone two laps ahead of the field, and he cruised to the victory. Three months after the race, however, Mears would suffer severe leg injuries in a practice crash at Sanair.
