Article C9.8.3
Gear Selection and Change Initiation
Chapter: C9
In Simple Terms
While the car is moving, drivers cannot change what the lowest gear available is. Each gear change must be deliberately selected by the driver and happens right away, unless the engine's over-rev protection system blocks it. The delay time between gear change attempts must stay consistent throughout the race.
- Minimum selectable gear cannot be changed while the car is in motion
- Each gear change requires a separate, intentional driver input
- Gear changes engage immediately unless over-rev protection prevents it
- De-bounce time (delay between gear change inputs) must remain fixed and consistent
Official FIA Text
Minimum selectable gear must remain fixed while car is moving. Each gear change must be separately initiated by driver and engaged immediately unless over-rev protection rejects request. De-bounce time must be fixed.
