| UN R125: Proposal for a Supplement 5 to the original text, a Supplement 4 to the 01 series, a Supplement 4 to the 02 series, and a Supplement 1 to the 03 series of amendments |

Proposal to amend para. 5.1.1.3. to adjust the lower vertical datum point from 5 degrees to 4 degrees below the horizontal and update the corresponding figure in Annex 4, Figure 1. This harmonizes the location of the lower datum point with the angle of obstruction requirement in para. 5.1.3., resolving an inconsistency between the allowed area of obstruction and the mandated transparent area of the windscreen. |

| Towards a Global Harmonization for Automated Shuttles |
| Reference Number: GRVA-26-06 |
|
Document presents automated shuttles as vehicles designed for public transport with autonomy by design, typically featuring fewer than 10 seats and often limited to 50 km/h maximum speed. Shuttles are deployed globally but are incompatible with current UN vehicle categories: category M1 does not accommodate standing passengers and is incompatible with crashworthiness regulations, while M2/M3 Class A construction alignment is prevented by the fewer-than-10-seat threshold. Proposal calls for a workshop organized by the GRSG/GRVA task force on automated vehicle categories to engage stakeholders and confirm need for an international category or class, addressing administrative questions, alignment with M2/M3 regulations, seating capacity, dimensions, weight, speed limits, and bidirectionality options. |

| ESRI: Proposal of terms of reference for the task force on the Exchange of Scenario-Relevant Information |
| Reference Number: GRVA-26-05 |
|
Proposal to establish terms of reference and rules of procedure for the Task Force on Exchange of Scenario-Relevant Information. The TF on ESRI shall propose procedures to facilitate sharing of information under WP.29 that can support the use of traffic scenarios for assessment of vehicles, equipment, and parts performing the dynamic driving task, and shall develop proposals concerning information structuring, information exchange management, public availability of information, and application recommendations. The TF on ESRI shall not propose scenarios for use in regulations, propose a regulatory database or catalogue, propose requirements for scenario use in regulations, or develop regulatory provisions. The TF on ESRI shall aim to develop procedures facilitating continuous improvement of vehicle safety, exchanges among Contracting Parties, application of scenario-related provisions, and efficient procedures for information exchange. The TF on ESRI shall present outcomes within two years from approval of these terms of reference by GRVA. The TF on ESRI is a subsidiary body of GRVA, open to all WP.29 participants, managed by a chairperson or co-chairs from Contracting Parties. Meetings shall be held in public, either in person or online. Decisions shall be reached by consensus. |
