One Minute Signal and Fifteen Second Signal

In Simple Terms

When the one-minute signal is given, teams must start their engines. By the fifteen-second signal, all team personnel must be completely off the grid. If any team member touches the car or its equipment after the fifteen-second signal, the driver must start the race from the pit lane instead of the grid, and will receive a drive-through penalty.

• Engines must be started after the one-minute signal
• All team personnel must leave the grid before the fifteen-second signal
• Touching the car or equipment after fifteen seconds results in a pit lane start
• A drive-through penalty is applied for any pit lane infractions related to this rule
