1940

Wilbur Shaw was the first driver to win two consecutive 500s. It was his third win in a four-year span, and the year in the middle he came in second.

Though Shaw's accomplishment was impressive, the race itself was unspectacular. Because of a drizzling rain the final 125 miles were run under yellow so Shaw cruised to an unchallenged victory, with Rex Mays second and Mauri Rose third.

This turned out to be Shaw's final 500 victory, but he would have another important role to play in the Speedway's history a few years later.

Although race day was free of death, earlier in the month driver George Bailey was fatally burned.
