Proposal to establish UN Regulation on Category Y vehicle crash safety covering frontal, rear-end, and lateral collision protection. The regulation specifies requirements for fuel system integrity, electrical shock protection, and crash compatibility for vehicles without occupants. Requirements address liquid fuel leakage limits, hydrogen storage system integrity, rechargeable energy storage system protection, and electrical safety post-impact. Testing procedures reference existing UN Regulations 94, 95, 137, and 153. Approval processes, conformity procedures, and technical specifications are detailed, including test methods for frontal, lateral, and rear-end impacts with measurement requirements and alternative procedure provisions.
