Updated proposal as of 18 March 2026.
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.
Proposal to clarify application of UN R139 to vehicle submitted for approval under the regulation (i.e., equipped with a brake assist system).
Proposal to clarify the scope of UN R140 to vehicles submitted for approval under the Regulation (i.e., vehicles equipped with ESC).
