 | | Officiallyincorporated on February 21, its purpose was to organize and promote thesport of stock car racing on sanctioned high-speed oval circuitsand a few road courses. |
 | | While most tracks are ovals, others are tri-ovals, quad-ovals, triangular, or ovals with unequal ends.Courses also differ in degree of banking on the curves, with differences in degree of banking and course length contributing todifferent top speeds on various courses. |
 | | Asa safety measure to reduce speeds at the two fastest tracks (Daytona International Speedway and Talladega), restrictor plates must be added to carburetors torestrict airflow and, therefore, power. |
