31. The expert from Germany proposed to indicate in the communication form in Annex 1 of UN Regulation No. 149 if headlamps may be able to produce driver assistance projection according to UN Regulation No. 48 (GRE-88-09). GRE adopted this proposal and requested the secretariat to submit it for consideration and vote at the November 2023 sessions of WP.29 and AC.1 as part of draft Supplement 2 to the 01 series of amendments to UN Regulation No. 149.

24. The expert from GTB introduced a proposal that allows a road projection pattern for predicted trajectory (ECE/TRANS/WP.29/GRE/2023/7). The expert from France proposed modifying the speed limit, in conjunction with ECE/TRANS/WP.29/GRE/2023/8 (see the next paragraph). The expert from Japan sought a proof that this pattern would not negatively affect other road users. The Chair invited GTB to liaise with Japan on this matter.

25. The expert from GTB proposed amendments that extend the possibility to project driver assistance symbols and patterns to the passing-beam headlamps of adaptive front-lighting systems (AFS). These amendments were accompanied by a corresponding amendment to UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2023/8 and GRE-88-25-Rev.1). GRE adopted the proposals, as laid down in GRE-88-25-Rev.1, and requested the secretariat to submit them for consideration and vote at the November 2023 sessions of WP.29 and AC.1 as draft Supplement 2 to the 01 series of amendments to UN Regulation No. 149, part of draft Supplement 19 to the 06 series of amendments, part of draft Supplement 6 to the 07 series of amendments and part of draft Supplement 4 to the 08 series of amendments to UN Regulation No. 48.

31. The expert from Germany proposed to indicate in the communication form in Annex 1 of UN Regulation No. 149 if headlamps may be able to produce driver assistance projection according to UN Regulation No. 48 (GRE-88-09). GRE adopted this proposal and requested the secretariat to submit it for consideration and vote at the November 2023 sessions of WP.29 and AC.1 as part of draft Supplement 2 to the 01 series of amendments to UN Regulation No. 149.

21. The expert from GTB tabled a proposal for amendments to UN Regulations Nos. 48 and 149 that extended the possibility of projecting driver assistance symbols and patterns to passing-beam headlamps of adaptive front-lighting systems (AFS) (ECE/TRANS/WP.29/GRE/2022/21, as amended by GRE-87-30). GRE agreed to modify the beginning of paragraph 5.35.3. to read “Neither flashing nor transforming of …”. In view of some comments and reservations about the possible distraction of other road users in urban traffic, GRE agreed to revert to this proposal at the next session, based on a revised document to be prepared by the authors.
