The race

The race begins with a warm-up lap, after which the cars assemble on the starting grid in the order they qualified. This lap is often referred to as the formation lap, as the cars lap in formation with no overtaking (although a driver who makes a mistake may regain lost ground provided he has not fallen to the back of the field). The warm-up lap allows drivers to check the condition of the track and their car, gives the tyres a chance to get some heat in them to get some much-needed traction, and gives the pit crews time to clear themselves and their equipment from the grid.

Once all the cars have formed on the grid, a light system above the track indicates the start of the race: five red lights are illuminated at intervals of one second; they are all then extinguished simultaneously after an unspecified time (typically less than 3 seconds) to signal the start of the race. The start procedure may be abandoned if a driver stalls on the grid, signalled by raising his arm. If this happens the procedure restarts: a new formation lap begins with the offending car removed from the grid. The race may also be restarted in the event of a serious accident or dangerous conditions, with the original start voided. The race may be started from behind the Safety Car if officials feel a racing start would be excessively dangerous, such as extremely heavy rainfall. There is no formation lap when races start behind the Safety Car.

Under normal circumstances the winner of the race is the first driver to cross the finish line having completed a set number of laps, which added together should give a distance of approximately 305 km (190 mi) (260 km (160 mi) for. Race officials may end the race early (putting out a red flag) due to unsafe conditions such as extreme rainfall, and it must finish within two hours, although races are only likely to last this long in the case of extreme weather. Drivers may overtake one another for position over the course of the race and are 'Classified' in the order they finished the race. If a leader comes across a back marker (slower car) who has completed fewer laps, the back marker is shown a blue flag  telling him he is obliged to allow the leader to overtake him. The slower car is said to be 'lapped' and, once the leader finishes the race, is classified as finishing the race 'one lap down'. A driver can be lapped numerous times, by any car in front of him. A driver who fails to finish a race, through mechanical problems, accident, or any other reason is said to have retired from the race and is 'Not Classified' in the results. However, if driver has completed more than 90% of the race distance, he will be classified.

When required, the (above, driven by  will lead the field around) the circuit at reduced speed, until race officials deem the race safe to continue.

Throughout the race drivers may make  to change tyres and repair damage (until the 2010 season they could also refuel). Different teams and drivers employ different pit stop strategies in order to maximise their car's potential. Two tyre compounds, with different durability and adhesion characteristics, are available to drivers. Over the course of a race, drivers must use both. One compound will have a performance advantage over the other, and choosing when to use which compound is a key tactical decision to make. The softer of the available tyres are marked with a green stripe on the sidewall to help spectators to understand the strategies. Under wet conditions drivers may switch to one of two specialised wet weather tyres with additional grooves (one "intermediate", for mild wet conditions, such as after recent rain, one "full wet", for racing in or immediately after rain). If rain tyres are used, drivers are no longer obliged to use both types of dry tyres. A driver must make at least one stop to use both tyre compounds; up to three stops are typically made, although further stops may be necessary to fix damage or if weather conditions change.
