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.
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 Task 3 developed interpretations and guidance for implementation, consolidated in a draft Guidance and Interpretation Document presented as informal document GRVA-25-20, with remaining items for refinement at a July Brussels hybrid joint IWG/WS session.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.
The Task Force on Vehicular Communications held a hybrid meeting on 23 January 2026, with presentations from Japan, CAICT China, and Car-to-Car Communications Consortium covering communications approaches to improve protection of vulnerable road users. The 14th VCTF meeting is scheduled for Wednesday 11 June 13:00–16:00 CET to discuss tests and ideas for improving VRU protection through communications. The Future Networked Car Symposium will be held in hybrid format on 9 July 2026 at Palexpo Geneva, jointly organised by UNECE and ITU, with the WP.29 related session in the morning of Thursday 9 July.
The AI IWG held four meetings between January and April 2026, with future meetings scheduled for June 2026. Co-Chairs are from the UK, Japan, and the U.S.; Co-Secretaries represent IEEE, CITA, and SAE. WP.29 approved an updated Terms of Reference in March 2026. The IWG has compiled literature on regulated automotive safety systems using AI (AI-08-03), created draft documents on Terms & Definitions (AI-06-03), use cases (AI-07-03), and guiding questions (AI-08-07). An initial consolidated draft document (AI-09-06) addresses what AI is and how it is used in the automotive sector, what benefits and risks it presents, and emergent practices for AI use and risk management. Initial outputs will be reported to WP.29 at the June 2026 meeting.
The workshop on scenarios discussed scenario-related information-sharing procedures and exchange, including to facilitate implementation of regulations using scenario-based assessments, develop administrative procedures to gather scenario-related information from CPs and NGOs, identify useful information to share, and clarify scenario use needs. At the same time, the workshop explicitly excluded activities such as creating a scenario catalogue and/or database, developing regulatory scenarios, and developing methodologies to create and derive scenarios for regulatory purposes. The group discussed whether scenarios work should operate as a dedicated working group under GRVA or as part of an existing group, considering resource constraints and the importance of supporting WP.29 activities like ADS and ADAS regulations.
Proposal to establish an informal working group on Exchange of scenario-relevant information (ESRI) as a subsidiary body of GRVA to develop procedures facilitating the sharing of DDT-relevant building blocks and knowledge from performance analyses and incident investigations, to structure such information to support scenario development and use, to propose means for managing and publicly sharing information in accordance with WP.29 procedures, and to provide recommendations for application and management, with outcomes to be presented within two years from approval to form the IWG by GRVA.
Proposal to amend para. 5.6.1.2.7. to increase the maximum RCP operating range from 6 m to 15 m. UN R79 currently limits the maximum RCP operating range to 6 m, resulting in effective usable range of 2 or 3 m due to radio wave-based ranging inaccuracy. A 15-meter range would enhance RCP function usefulness and safety, reducing driver movement and blind areas. RCP systems with extended ranges have been used in large markets without identified safety threats. The amendment is proposed as a supplement to the 03 and 04 series of amendments to UN R79.
