Road racing
In North America, road racing is motor racing held on a paved closed circuit with both left and right turns. Road racing is therefore distinct from both off-road racing and oval track racing; the latter is common in North America and involves turning in only one direction (usually left, counter-clockwise). Road racing may be on purpose-built race tracks (called road courses) or on temporary circuits, such as closed-off airport runways and public roads, typically street circuits. A "roval" is a road course incorporating parts of an oval track and its infield, such as is used for the 24 Hours of Daytona at Daytona International Speedway.
