Starting the F1 race

All the preparation � the development back at the factory, the testing, the practices, the qualifying, the debriefs � lead up to the moment of the start. A famous Australian driver once said, �when the flag drops, the bullshit stops�. There is no longer a starting flag but the basic premise still holds good.
The start procedure is as follows:

1. Start minus 30 minutes and the cars can be driven from the pit lane to their grid positions.
2. Start minus 15 minutes, the pit lane exit is closed and any car that has not yet left the pit lane will have to begin its race from there after the field has gone by on the first racing lap. This is not a good start to your race!
3. Start minus five minutes: the grid is cleared of all personnel (except the drivers of course!).
4. A green light signals the beginning of the warm up (or formation) lap. Any car slow away can only regain its grid position if it hasn�t been passed by every other car. Otherwise, it must start from the back of the grid. Other than passing slow-moving cars with an obvious problem, or regaining a grid position lost due to a slow start, drivers cannot overtake on the warm up lap.
5. At the end of the warm-up lap the cars take up their grid positions. When the last car is in place, a race official walks on to the back of the grid, signals the race starter with a flag, and leaves the grid once more. The race starter then initiates the starting light procedure.
6. A series of five lights on the start line gantry (a bridge-like framework set high over the track) come on in sequence. When the fifth light comes on, the race can start anytime between 0.2 and three seconds afterwards (the gap is pre-programmed by the starter before the race but kept secret).

And they�re off! The race is on the moment the lights go out.
