Dirt track racing is a form of motorsport where specially designed cars race on oval tracks made of dirt or clay. The surface provides unique challenges, as it can change during a race due to weather and tire wear. This type of racing is popular in many regions, especially in the United States, where it attracts both amateur and professional drivers. Races can feature various classes of vehicles, including modified cars, late models, and sprint cars. Events are often held on weekends, drawing large crowds who enjoy the excitement of high-speed competition and the skill required to navigate the slippery surface.
