The Eighteenth GRVA Workshop on ADS will be held on 1 June 2026 from 12:30–14:30 Geneva time online via MS Teams. The workshop will adopt the provisional agenda and minutes of the 16th GRVA workshop on ADS. Participants will receive briefing on highlights from the informal part of the 25th GRVA held in Montreal from 18–22 May 2026. The workshop will review the timeline for delivering the Guidance and Interpretation Document as an informal document at the 200th WP.29 session and as an official document for consideration at the March 2027 session. OPIs will inform participants on their development activities for the guidance and interpretation document.

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.
