12. GRSG resumed consideration of the new UN Regulation No. [165] 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 16.1.3.1. 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 16.1.3.1. 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 16.1.3.1., 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 16.1.3.1., revised by IWG VRU-Proxi.

19. The expert from Japan on behalf of IWG on VRU-Proxi introduced GRSG-123-15-Rev.1, superseding ECE/TRANS/WP.29/GRSG/2022/10 to clarify the type-approval testing process. The expert from the United Kingdom argued that in paragraph 16.1.3.1., the current terminology “permanent” would potentially relieve the responsibility of drivers in case of an accident involving vulnerable road users. The experts from the Netherlands and the United Kingdom agreed. Therefore, GRSG discussed GRSG-123-31, to provide two alternative texts, among others, to paragraph 16.1.3.1. and also to avoid subjectivity of the term “obstruction” as proposed by the expert from France (second alternative sentence in square brackets). The expert from EC endorsed the sentence proposed by the expert from France. The expert from Japan proposed to further discuss the proposal within IWG.

20. GRSG adopted ECE/TRANS/WP.29/GRSG/2022/10 as amended by annex IV to the report (GRSG-123-15-Rev.1). The secretariat was requested to submit the proposal as draft Supplement 2 to the original version of UN Regulation No. 158 (Reversing motion) to WP.29 and AC.1 for consideration and vote at their November 2022 sessions. Moreover, GRSG agreed to submit GRSG-123-31 to IWG VRU-Proxi, for a possible amendment of paragraph 16.1.3.1. that would amend the draft Supplement 2 to the original version of UN Regulation No. 158. Consideration would eventually be at its October 2022 session.
