Dirt track racing is a form of motorsport that takes place on oval or circular tracks made of dirt or clay. These tracks can vary in size and shape, and the races often feature modified cars, sprint cars, or late models. The surface provides unique challenges, as drivers must adapt to changing conditions, such as moisture levels and track grip. Races typically involve multiple laps, with drivers competing for the fastest time and position. Popular in the United States, dirt track racing has a dedicated fan base and is often associated with local events and community gatherings. Notable series include the World of Outlaws and NASCAR's dirt events.
