Five Minute Signal Wheels and Blankets

In Simple Terms

When the 5-minute signal is given before the race start, all cars must have their wheels properly attached. Teams must also unplug their tire blankets (heating devices) at this point and cannot plug them back in unless the start is delayed or cancelled.

• All cars on the grid and in the pit lane fast lane must have wheels fitted when the 5-minute signal appears
• Tire blankets must be disconnected from power at the 5-minute signal
• Tire blankets cannot be reconnected unless there is a delayed or aborted start
• This rule ensures cars are race-ready and prevents last-minute technical adjustments
