12. GRSG resumed consideration of the new UN Regulation No.  on reverse warning, with reference to UN Regulation No. 158 as the requirements for the pause switch. However, a proposal was yet to be provided by GRSG on this subject. GRSG also recalled that it was agreed to submit a proposal (GRSG-123-31) to IWG VRU-Proxi, for a possible amendment of paragraph 184.108.40.206. which would amend draft Supplement 2 to the original version of UN Regulation No. 158, that had been submitted for consideration and vote at the November 2022 sessions of AC.1 and WP.29 (ECE/TRANS/WP.29/2022/123). The expert from Japan informed GRSG that proposal had not yet been provided by IWG VRU-Proxi. Therefore, GRSG considered GRSG-124-29, tabled by the experts from France and Japan, proposing to remove the amendment of paragraph 220.127.116.11. since the opportunity for temporary obstruction without any countermeasure preserving safety was not acceptable. While awaiting a further proposal from the IWG, GRSG adopted GRSG-124-29. The secretariat was requested to submit ECE/TRANS/WP.29/2022/123 as amended by GRSG-124-29 (ECE/TRANS/WP.29/2022/123/Rev.1), deleting the proposed amendment to paragraph 18.104.22.168., for consideration and vote at the November 2022 sessions of WP.29 and AC.1. In the meantime, GRSG expected to consider at its March 2023 session, a new proposal of amendments to paragraph 22.214.171.124., revised by IWG VRU-Proxi.
