ADS: Consolidated inputs for guidance and interpretation document
Reference Number: ADS-20-12/Rev.1

This document consolidates inputs from Officers of Principal Interest (OPI) on the Automated Driving Systems (ADS) Guidance and Interpretation Document and organizes content into regulatory text, guidance, comments, and examples to facilitate April-May 2026 Workshop discussions. The document provides interpretation of UN Global Technical Regulation and UN Regulation requirements on ADS, addressing safety performance of the Dynamic Driving Task in nominal, critical, and failure situations; interactions between ADS and users; post-deployment safety monitoring through Safety Performance Indicators; Safety Management System audit criteria; and simulation credibility frameworks for verification and validation, while emphasizing that guidance does not introduce new requirements and that the Regulations remain the sole authoritative texts under 1958 and 1998 Agreements.

Meeting Sessions: 20th ADS session (27 Apr-1 May)
