In a motorsports race, the pole position is usually the best and "statistically the most advantageous" starting position on the track. The pole position is usually earned by the driver with the best qualifying times in the trials before the race. The number-one qualifying driver is also referred to as the pole-sitter. The pole position, pole sitter, starts the race "at the front of the starting grid. This provides the driver in the pole position the privilege of starting ahead of all the other drivers".

The 1946 AAA Championship Car season was the first season of American Championship car racing following World War II. After four years without racing in the United States, the AAA Contest Board was initially concerned about having enough races, enough entrants, and suitable equipment, for a 1946 season. Even the Indianapolis 500 was in doubt, as the Indianapolis Motor Speedway was neglected during the war. Track owner Eddie Rickenbacker sold the track to Tony Hulman in November 1945, by which point it had fallen into a terrible state of disrepair. As the season progressed, it proved to be a success, and marked a successful return of the National Championship. Hulman's swift and herculean effort to renovate Indianapolis allowed for the 1946 Indianapolis 500 to be run as scheduled on May 30, and it was won by George Robson.
