Dirt track racing is a form of motorsport held on clay or dirt surfaced oval race tracks often used for thoroughbred horse racing. Dirt track racing started in the United States before World War I and became widespread during the 1920s and 1930s using both automobiles and motorcycles. Two different types of race cars dominate — open wheel racers in the Northeast and West and stock cars in the Midwest and South. While open wheel race cars are purpose-built racing vehicles, stock cars can be either purpose-built race cars or street vehicles that have been modified to varying degrees. There are hundreds of local and regional racetracks throughout the nation. The sport is also popular in Australia, New Zealand, Canada, South Africa and the United Kingdom.
