The Informal Working Group on Automated Driving Systems identified topics for future consideration organized into four lists: items not addressed in original versions of the GTR/UNR; existing items requiring amendment or improvement; items relating to operational implementation; and other items. List 1 includes remote assistance, ODD description taxonomy, external human-machine interface provisions, and connectivity considerations. List 2 includes ADS to ADAS transitions, Data Storage Systems for Automated Driving, ADS deactivation, in-service monitoring and reporting, and safety case requirements. List 3 addresses interpretation document improvements, mutual recognition provisions review, system updates and thresholds, and practical implementation of in-service monitoring. List 4 includes text streamlining to remove duplication and improve clarity.

Since January 2026, the group accepted proposals ADS-20-15, ADS-20-16, and ADS-20-48/Rev.1 for minor amendments. Working documents WP.29/2026/139 and WP.29/2026/137 were submitted for WP.29’s 199th session. Two informal documents (ADS-20-59 and ADS-20-60) will amend these working documents. GRVA seeks a three-year mandate extension for the informal group to address identified future work items beyond June 2026.

The document addresses on-board authentication and authorization in connected vehicles, a complex area involving multiple stakeholders, use cases, implementations, and standards. The core challenge is distinguishing legitimate remote interactions from misuse, manipulation, and integrity loss. Discussions have occurred since 2023 across GRVA, CS/OTA, and WP.29. FIA seeks feedback on establishing the topic and will develop a scoping document and demonstrator based on select use cases including accident investigation, law enforcement, emergency response, energy monitoring, battery tracking, parts replacement, and ITS-related safety. Contracting parties are invited to submit comments and use cases by 15 June 2026 for consideration at the November WP.29 session.

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.

Proposal to insert new para. 3.1.1. and 3.1.2. requiring manufacturers to provide information to approval authorities prior to application and upon extension of type approval; insert new para. 3.2.2. requiring manufacturers to provide summaries of safety definitions, driver safety levels, traffic rules assessment, and testing for each territory where ALKS can be active; and insert new paras. 4.6. to 4.6.6. establishing procedures for approvals covering multiple territories, including notification of receiving approval authorities at least 30 days before approval, review periods, and dispute resolution under the 1958 Agreement. OICA and CLEPA do not support mandatory pre-announcement but would support sharing Safe Operation documentation and lists of compliant territories during the approval process.

This document is a draft Guidance and Interpretation Document (GID) for UN Global Technical Regulation and UN Regulation on Automated Driving Systems, based on GRVA/2026/3 as amended by GRVA-24-29 and WP.29-198-09. The GID provides explanatory text, guidance, and examples to support implementation of ADS requirements without introducing new obligations. It covers scope, definitions, application for approval, approval procedures, ADS performance requirements in nominal, critical, and failure situations, interactions between ADS and users, safety management systems, test environments including simulation credibility frameworks, safety case requirements, post-deployment safety monitoring with reportable occurrences, and compliance assessment procedures. The document clarifies terminology including operational states of ADS features, critical occurrences, driving situations, and mitigated risk conditions, and provides detailed guidance on ODD definition, safety case structure, confirmatory testing approaches, and in-service reporting templates with threshold definitions for critical occurrences.

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.
