19. The expert from France presented informal document GRSP-78-13-Rev.1, which merged ECE/TRANS/WP.29/GRSP/2025/27 and ECE/TRANS/WP.29/GRSP/2025/44 by France and OICA, respectively. The resulting proposal aims to correct and clarify the text of the regulation, and to modify the current wording which creates misunderstandings and a non-harmonized application of the regulation by technical services. GRSP adopted informal document GRSP-78-13-Rev.1 (as reproduced in annex IV) and requested the secretariat to submit it as proposals for supplement 1 to the 10 series of amendments, supplement 2 to the 11 series of amendments and supplement 1 to the 12 series of amendments to UN Regulation No. 17 to the June 2026 sessions of WP.29 and the Administrative Committee of the 1958 Agreement (AC.1).

42. GRSP noted that at its November 2025 session, WP.29 reaffirmed its objective to adopt all documents related to the review of existing UN Regulations related to Automated Driving Systems (ADS) at its June 2026 session and invited the Chairs of the Working Parties to consider various strategies to ensure timely preparation of the required documents. This corresponded to option 1 in informal document WP.29-197-25 and would require all proposals under this agenda item to be adopted by GRSP on this session.

43. Following a general update by the expert from Germany on the first day of the meeting, the GRSP Task Force on Automated Vehicles Regulation Screening (TF-AVRS) continued work on the margins of the meeting to refine the proposals and submitted a number of informal documents to amend the proposals in working documents under this agenda item.
