Oval track racing

Oval track racing is a form of closed-circuit automobile racing that is contested on an oval-shaped track. An oval track differs from a road course in that the layout resembles an oval with turns in only one direction, almost universally left (counter-clockwise orientation). Oval tracks are dedicated motorsport circuits, used predominantly in North America. They often have banked turns and some, despite the name, are not precisely oval, and can have unique variances in shape.

Oval track racing is the predominant form of auto racing in the United States. According to the 2013 National Speedway Directory, the total number of oval tracks, drag strips and road courses in the United States is 1,262, with 901 of those being oval tracks and 683 of those being dirt tracks. Major forms of oval track racing include stock car racing, open-wheel racing, sprint car racing, modified car racing, midget car racing and dirt track motorcycles.

Among the most famous oval tracks in North America are the Indianapolis Motor Speedway and Daytona International Speedway. Notable ovals in other countries include Rafaela in Argentina, Motegi in Japan, Lausitzring in Germany, the Calder Park Thunderdome in Australia, Brooklands and Rockingham in the United Kingdom, Monza in Italy, and Montlhéry in France.
