Since the 24th session of GRVA, the Workshops on Automated Driving Systems held four sessions, with meetings in Shanghai and Bangkok. Administrative requirements for the draft UNR/GTR ADS require no further discussion. Task 3 developed interpretations and guidance for implementation, consolidated in a draft Guidance and Interpretation Document presented as informal document GRVA-25-20, with remaining items for refinement at a July Brussels hybrid joint IWG/WS session. The GID will be made available in English, French, and Russian, with the IWG ADS maintaining it. Formal adoption is projected for November WP.29 following September GRVA discussion.

This Guidance and Interpretation Document (GID), based on GRVA/2026/3 as amended by GRVA-24-29 and WP.29-198-09, supports implementation of proposed UN Global Technical Regulation and UN Regulation on Automated Driving Systems. The GID, structured in table format with regulatory text and explanatory guidance with examples, facilitates interpretation of ADS requirements when applying them to particular vehicles or vehicle types. The document addresses ADS safety, system descriptions, operational design domains, performance in nominal, critical, and failure situations, interactions between ADS and users, manufacturer safety management systems, test environments including simulation credibility frameworks, safety cases, post-deployment safety monitoring, and compliance assessments including confirmatory testing. Materials will be restructured and refined for submission to GRVA’s September 2026 session.

Proposal to amend para. 137 to describe the seventeenth workshop organized in Bangkok, Thailand, together with the twentieth session of the IWG on ADS, where participants reviewed updates to the GID document sections prepared by the OPIs, resulting in a revised version of the GID document considered mature enough for presentation at the twenty-fifth GRVA session, with agreement that remaining open items should be finalized at the July 2026 workshop in Brussels, Belgium, and several minor amendments to the draft GTR/UN-R text derived from the Bangkok meeting discussions modified the text of the draft GTR/UN-R.
