17. The expert from the Task Force on Autonomous Vehicle Signalling Requirements (TF AVSR) reported on their activities to adapt UN Regulation No. 48 to the introduction of automated vehicles (GRE-89-19) and presented revised amendment proposals (ECE/TRANS/WP.29/GRE/2023/9/Rev.1 and GRE-89-14). GRE thanked TF AVSR for their efforts which were ahead of related activities in other WP.29 GRs. GRE noted that amending UN Regulation No. 48 would require a set of new definitions and vehicle (sub)categories which should first be harmonized among various GRs and adopted at the WP.29 level. GRE requested TF AVSR to continue liaising with other GRs with the aim to prepare updated amendment proposals for the next session of GRE.
