Proposal to delete this footnote 2 from the regulation
22. The expert from EC proposed to delete a footnote in UN Regulation No. 138 stating that, at this stage, only acoustic measures should be developed in order to overcome the concern of reduced audible signals from electrified vehicles and that alternative, non-acoustic measures, should only be developed later by the respective Working Parties (GRs) (GRBP-80-13). According to her, other GRs should be requested to develop such alternative measures as soon as possible, given the serious public health concerns due to vehicle noise. The Chair replied that he would convey this request to WP.29 and that, for the time being, deleting of the footnote seemed to be premature.
