Standing Start Lights Sequence
Article 48.12
Standing Start Lights Sequence
Chapter: Chapter IV - The Race
In Simple Terms
F1 uses a five-light system for starts. After the formation lap, cars line up on the grid and the pit exit closes. Five red lights come on one at a time (one second apart), then all go out simultaneously - that's the start signal. This system prevents jump starts and ensures fair races.
- Formation lap led by pole position car
- Pit exit closes when cars take grid positions
- Five red lights illuminate one second apart
- Start signal: all red lights go out at once
Official FIA Text
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.
