Master switch location and marking

In Simple Terms

Every F1 car must have a red emergency cut-off switch on the dashboard that lets the driver instantly shut down the engine, fuel pumps, and rear lights in case of emergency. The switch must be clearly marked with a distinctive red spark symbol inside a blue triangle with white edges so it's easy to find in a crisis.

• Driver must be able to cut off ignition, fuel pumps, and rear lights with a single switch
• Switch must be located on the dashboard for quick access
• Switch must be spark-proof to prevent electrical hazards
• Switch must be marked with a red spark in a white-edged blue triangle for clear identification
