Should GRBP adopt the amendments proposals to the 04 series of amendments in ECE/TRANS/WP.29/GRBP/2025/13, they will be combined with the amendment proposal to the same series of amendments that was adopted at the previous session (ECE/TRANS/WP.29/GRBP/2024/23 as amended by GRBP-80-11).
GRBP will wish to continue the discussion on the complexity and possible splitting of UN Regulation No. 117 and will be informed about considerations of the Group of Interested Experts established for that purpose.
