Excerpts from session reports related to this document
GRE | Session 91 | 22-25 Oct 2024

21. The expert from GTB tabled proposals which introduced reversing projections. These proposals were submitted in a package with the corresponding amendments to UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2024/20, GRE-91-05). During an in-depth discussion, experts made numerous comments on the proposals. The expert from the United Kingdom did not see the need for reversing projections in the presence of reversing lamps. Based on the GRE feedback, the expert from GTB issued GRE-91-25 in which he summarized the comments received and previewed revised proposals that would be submitted to the next session. GRE invited all experts to check GRE-91-25 and provide any additional comments to GTB before 15 November 2024, with the aim to prepare a new working document for the next session.
