16. The experts from France and Germany, in their capacity of Co-chairs of the Informal Working Group (IWG) on a Quiet Road Transport Vehicles (QRTV) Regulation under 1958 Agreement, reported on the status of QRTV-related work (GRB-63-13). GRB noted that WP.29, at its March 2016 session, would consider a draft QRTV Regulation (ECE/TRANS/WP.29/2016/26). At its November 2015 session, WP.29 decided to extend the mandate IWG on QRTV Regulation with a view to addressing concerns raised by WBU (ECE/TRANS/WP.29/1118, paras. 24, 100-102), namely sound pressure levels, optional installation of the Acoustic Vehicle Alerting System (AVAS) pause switches and sound emissions when stationary. IWG on QRTV Regulation would also consider the possible extension of the scope of the QRTV regulation to vehicles of L categories.
17. To reflect the above new tasks, the experts from France and Germany proposed to update the Terms of Reference (ToR) of IWG on QRTV Regulation (GRB-63-14). GRB adopted the revised ToR, as reproduced in Annex VII.
