Start Sequence

The start sequence is the procedure by which a grand prix is started. Once the grid has formed following the formation lap, and the medical car is in position at the back of the grid, the race director, from a control box looking out over the grid, initiates the sequence.

Five red lights above the start line are illuminated one by one and then after a random pause, they are extinguished, signalling the start of the race.

The random pause can be between 1 and five seconds and is to ensure the drivers don’t try to anticipate the start.
