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.
This document is a draft Guidance and Interpretation Document (GID) for UN Global Technical Regulation and UN Regulation on Automated Driving Systems, based on GRVA/2026/3 as amended by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.
Consolidated document with all changes GTR and UN Regulation as of 13 April 2023.
