Excerpts from session reports
GRSP | Session 78 | 1-4 Dec 2025

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.
