Proposal to establish a new UN Regulation for vehicles of category N₁ regarding protection of fuel system integrity, protection against electrical shock, and vehicle crash compatibility in frontal, rear-end, and lateral collisions. The Regulation integrates provisions from UN R94, UN R95, UN R137, and UN R153. For frontal impact, vehicles not exceeding 2,500 kg follow UN R94; vehicles exceeding 2,500 kg but not exceeding 3,500 kg follow UN R137. Lateral impact provisions derive from UN R95, excluding the side pole impact test. Rear-end impact provisions derive from UN R153 without modification. Specifications address fuel leakage limits, hydrogen storage system integrity, electrical shock protection from rechargeable energy storage systems, and energy absorption to prevent aggressive vehicle behavior in collisions.
