19. The representative of Germany proposed (GRVA-23-04) to reinstate in UN Regulation No. 157 on Automated Lane Keeping System (ALKS) the obligation for a granting Type-Approval Authority to inform each other Contracting Party (respectively the Type-Approval Authority) before issuing the Type-Approval for which the manufacturer has expressed the intention to introduce ALKS in that country and has therefore provided evidence of compliance with the relevant national traffic rules (according to Annex 1-Appendix 2). The delegations noted similar discussions under agenda item 4(a) and agreed to resume discussion on this issue at the January 2026 session.

20. The representative of China presented (GRVA-23-44) research findings from the Research Institute of Road Safety (RIRS) under the Ministry of Public Security on the application of testing methodology on traffic rule Compliance for ADS-equipped vehicles. The study identified key safety risks, such as inconsistent adherence to traffic regulations during ADS testing, and proposed a multi-pillar testing approach combining simulation, closed-field, and real-road testing to ensure comprehensive coverage of traffic rules. The methodology included scenario-based testing, the development of 398 evaluation criteria to verify compliance within the Operational Design Domain (ODD). These findings were being implemented in the ADS evaluation in the Level 3 pilot project and were expected to inform future standards for ADS traffic rule compliance.

The representative of the United States of America, Co-Chair of the IWG on the Safe Use of Automated Driving Systems in Traffic (SUAT) under the Global Forum for Road Traffic Safety (WP.1), invited the representative of China to present these activities to the informal group at one of the next sessions.
