Helmet Position

Chapter: C12

In Simple Terms

The driver's helmet must be positioned within a specific zone when sitting normally in the car—the back of the helmet needs to fall between two measurement points (50-125mm from a reference line), and it must sit below an imaginary line connecting the roll structure points. This ensures the helmet is properly positioned for maximum safety protection.

  • Helmet back must be positioned between X coordinate -50 and -125mm when driver is seated normally
  • Helmet must sit below a line drawn from the front fixing axis of the Secondary Roll Structure to a point 75mm below the highest point of the principal roll structure
  • Driver must be facing forwards during this measurement check
  • This positioning ensures optimal protection in the cockpit safety structure
Official FIA Text

The driver's helmet must lie below a line drawn between the front fixing axis of the Secondary Roll Structure and a point 75mm vertically below the highest point of the principal roll structure.
