Road racing can be of two types: in the first, car or motorcycle races are run on specially built, closed circuit courses in the second, public roads are temporarily closed off for the purpose of conducting a race. Notable examples of this include the Monaco Grand Prix which is conducted on the city streets of the small principality, the Mille Miglia, the Targa Florio,and the Isle of Man. The Tourist Trophy, probably the most famous motorcycle race of its type, takes place over the Snaefell mountain course, as well as the Northwest 200 in Ireland. Today, some small portion of these automobile race tracks are called temporary street courses.

Of the former, closed circuit type, purpose-built race tracks are used that, due to their irregular shapes and many turns and curves, resemble true road courses. Due to safety and insurance concerns, this style of racing has largely supplanted true road racing, particularly in Europe

 

Road racing is also occasionally conducted using the infield and oval portions of tracks, such as the 24 Hours of Daytona. Road racing has become a featured part of many racing video games.


Global road courses:-

Global road-racing series such as Formula One car racing and MotoGP motorcycle racing are almost always conducted on dedicated race tracks—with only a few exceptions. Several of these tracks are world-renowned, such as the circuits at Le Mans, Imola, and Silverstone.

Recent expansion of these international series has resulted in dedicated tracks being built in Qatar in the Middle East, Sepang in Malaysia, and Shanghai in China.
