This document presents activities in China on a testing methodology for traffic rule compliance by ADS-equipped vehicles. The document addresses safety risks from inconsistent adherence to traffic regulations and proposes that ADS shall comply with traffic rules applicable to the dynamic driving task in the country of operation, applying the same rules as human drivers. It describes 12 core driving tasks categorized into safety, operation, and interaction clusters, 398 evaluation criteria, and 4 traffic elements. The methodology integrates virtual simulation, closed-site testing, and real-road testing to verify ADS compliance with traffic rules comprehensively within the operational design domain and in critical scenarios.

Proposal to amend para. 5.3.3.2. to correct a referencing error by replacing the reference to para. 5.1.4. with a reference to para. 5.3.1.1., which directly relates to mechanical parts of the steering transmission, thereby removing possible uncertainty or the need to liaise with the designated technical service or approval authority to confirm interpretation of the current text.

This document summarises the reviews conducted by the GR working parties on the fitness for ADS of UN Regulations and GTR for application to ADS vehicles. This document represents the current opinions of the experts at the time of submission, and the recommendations contained inside may evolve significantly during the next steps of the process of reviewing and amending Regulations.
