20. The Chair informed GRB about the proposal of the technical sponsors of IWG on Quiet Road Transport Vehicles (QRTV) for GTR to develop a draft UN Regulation on QRTV under the 1958 Agreement in parallel to a draft GTR on QRTV (ECE/TRANS/WP.29/1110, para. 100). GRB agreed with this proposal and decided, subject to WP.29 consent, to establish an IWG to develop a UN Regulation on QRTV under the 1958 Agreement and adopted the Terms of Reference (ToR) (GRB-60-11-Rev.1), as reproduced in Annex VI to this report. The new IWG should work in close cooperation with IWG QRTV for GTR, with the aim to draft the above mentioned UN Regulation based on audible alerts for the safety of vulnerable road users. GRB agreed that the scope of a new UN Regulation would initially cover electric and hybrid electric vehicles of categories M and N. In a second phase, the scope may be extended.
