Rearward Intrusion Laminate Reference Surface (RS-INTSN-LAM-RWD)

In Simple Terms

This regulation defines a specific reference surface inside the car's cockpit area that protects the driver in a rear-impact crash. It's an invisible 3D shape created by extending two profile lines across the width of the car, and the car's structure must meet safety requirements relative to this surface.

• Defines a safety reference surface for rear-impact protection in the driver's cockpit
• Created by extending two profile lines across the full width of the car (500mm in the Y direction)
• Used to ensure the car's structural design meets crash safety standards
• Part of the broader interlocking safety regulations that protect drivers
