Stock car racing is a form of automobile racing found mainly in the United States, Canada, New Zealand, Great Britain and Brazil. Traditionally, races are run on oval tracks measuring approximately ¼ mile to 2.66 miles (about 400 meters to 4.2 kilometres) in length, but are also raced on road courses[citation needed]. The National Association for Stock Car Auto Racing(NASCAR) is the world's largest governing body for stock car racing, and itsSprint Cup Series (named for its sponsor, Sprint Nextel Corporation) is the de facto premier series of stock car racing. Top level races are 200 to 600 miles (320-1000 km) in length. Average speeds in the top classes are usually within 70-80% of comparable levels of open wheel racing at the same tracks. Some stock cars may reach speeds of in excess of 200 mph (320 km/h) at tracks such as Indianapolis Motor Speedway and Lowe's Motor Speedway. For safety, devices such as restrictor plates may be used at Daytona International Speedway and Talladega Superspeedway that limit top speeds to approximately 187 mph (301 km/h).
