| Y-category crash protection: Draft proposal for a new UN Regulation |
| Reference Number: GRSP-TF-AVRS-25-02/Rev.1 |
|
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. |

| New general safety regulation for vehicles of category Y |
| Reference Number: GRSP-TF-AVRS-25-04/Rev.1 |
|
A new general safety regulation for vehicles of category Y, which are not designed to carry occupants, adds provisions requiring repetition of tests described in Annex 3 and Annex 4 when modifications affect the general form of vehicle structure or increase mass by more than eight per cent. For modifications affecting only interior fittings or mass increases not exceeding eight per cent, a simplified test in accordance with UN R94 in its 05 series of amendments or a partial test shall be carried out. The regulation incorporates requirements from UN R94, UN R95, UN R137, and UN R153, and proposes exempting vehicles with maximum design speed not exceeding 50 and 56 km/h from impact test procedures while requiring compliance with post-impact requirements. |

| GRSP AV Screening: Minutes of the 25th (April 2026) session |
| Reference Number: GRSP-TF-AVRS-25-07 |
|
The 25th session of the GRSP Task Force on Automated Vehicles Regulatory Screening (AVRS) was held online on 28 April 2026. The Task Force discussed regulatory frameworks for Y-category vehicles, including mass compatibility and crash test exceptions, and reviewed UN Regulation 127 on pedestrian protection for Y-category vehicles. The Task Force also addressed UN Regulation 12 feedback and identified minor mistakes in three proposals: ECE/TRANS/WP.29/2026/63, ECE/TRANS/WP.29/2026/65, and ECE/TRANS/WP.29/2026/71, which require corrections before submission to WP.29. |
