The national championship was sanctioned by the Contest Board of the American Automobile Association (AAA). The AAA first sanctioned automobile motorsports events in 1902. At first it used the rules of the Automobile Club of America (ACA), but it formed its own rules in 1903. It introduced the first track season championship for racing cars in 1905. Barney Oldfield was the first champion. No official season championship was recognized from 1906 to 1915, however, many races were held. Official records regard 1916 as the next contested championship season. Years later, retroactive titles were named back to 1902. These "post factum" seasons (1902–1904, 1906–1915, and 1917–1919) are considered unofficial and revisionist history by accredited historians.
