A flying start gone wrong for Ralf Schumacher

When the green lights are illuminated, the cars will begin the formation lap with the pole position driver leading. When the leading car returns to the grid all the cars must take up their grid positions, the pit exit lights will turn red and no cars may enter the track from the pit lane. Once the last car has taken up its grid position, the five red lights will be switched on one by one at one second intervals. The start will be signalled by the red lights being extinguished.
