During the first of the Twin 125 qualifying races for the Daytona 500, former Indy 500 driver Bruce Jacobi lost control at the exit of Turn 2 and flipped his Chevrolet upon entering the grass infield, eventually coming to a stop near the inside dirt bank. It is speculated that his roll cage failed during the crash. Jacobi suffered extensive head injuries and was in a coma for almost four years before passing away at Methodist Hospital in Indianapolis.
