16. The expert from Japan proposed clarifications (ECE/TRANS/WP.29/GRBP/2024/20 and GRBP-80-33) which were based on the considerations of the former Task Force on Quiet Road Transport Vehicles (TF QRTV). GRBP adopted the proposal and requested the secretariat to submit them for consideration and vote at the March 2025 sessions of WP.29 and AC.1 as Supplement 1 to the 02 series of amendments to UN Regulation No. 138.
