8. The expert of IWG SLR proposed to correct a reference to UN Regulation No. 148 in UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2023/13). GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the March 2024 sessions of WP.29 and the Administrative Committee (AC.1) as draft Supplement 20 to the 06 series of amendments, draft Supplement 7 to the 07 series of amendments, draft Supplement 5 to the 08 series of amendments and part of the draft new 09 series of amendments to UN Regulation No. 48. GRE also adopted this proposal as draft Supplements to the 03, 04 and 05 series of amendments to UN Regulation No. 48 but decided to keep them as pending for the time being, in order to combine them with other amendment proposals to the same series of amendments.

18. GRE recalled that, at its previous session, it had adopted a new 09 series of amendments to UN Regulation No. 48 and had decided to submit the proposal to the March 2024 session of WP.29, in order to editorially confirm these proposals at the present session.

19. The expert of OICA proposed to extend until 2032 the transitional provisions for heavy commercial vehicles and trailers in the draft 09 series of amendments (ECE/TRANS/WP.29/GRE/2023/28). GRE was not in a position to support the proposal.

20. The expert of OICA also introduced improvements and clarifications for the new draft 09 series of amendments (GRE-89-18). Following an in-depth discussion, GRE adopted these proposals, as amended, and agreed to merge them with the new draft 09 series of amendments to UN Regulation No. 48.

21. Against this background, GRE noted and endorsed a consolidated text of the draft 09 series of amendments to UN Regulation No. 48 (GRE-89-02-Rev.3) which had been prepared by IWG SLR and compiled the following documents that had been adopted at the present and previous sessions of GRE: ECE/TRANS/WP.29/GRE/2020/08/Rev.3, Annex II to ECE/TRANS/WP.29/GRE/88, ECE/TRANS/WP.29/GRE/2023/13, ECE/TRANS/WP.29/GRE/2023/19, ECE/TRANS/WP.29/GRE/2023/20, GRE-88-16-Rev.3, GRE-88-18, GRE-88-24, GRE-88-27, GRE-89-04 and GRE-89-18. The proposal would be submitted for consideration and vote at the March 2024 sessions of WP.29 and AC.1.

39. GRE recalled that, at its present and previous sessions, it had adopted GRE-88-17 and ECE/TRANS/WP.29/GRE/2023/13 as a Supplement to the 03, 04 and 05 series of amendments to UN Regulation No. 48 but had decided to postpone the submission of these amendments to WP.29, in order to combine them with future amendment proposals to the same series of amendments.
