Working Party on General Safety | Session 123 | 28 Mar-1 Apr 2022
Geneva
Agenda Item 4. (c)
UN Regulation No. 158 (Reversing motion)

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.

21. The expert from Japan, on behalf of the Task Force on Reverse Warning Sound issues of the Working Party on Noise and Tyres (GRBP), introduced the status report (GRSG-123-13) of the Task Force on the draft new UN Regulation on reversing alarm, adopted by GRBP at its seventy-fifth session. He explained that the proposed draft of the new UN Regulation referred to UN Regulation No. 158 on the requirements for the pause switch. The expert from OICA remarked that inconsistent cross references to UN Regulation No. 10 should be resolved in UN Regulations Nos. 158, 161 and 162. The expert from OICA also proposed that the reference to UN Regulation No.158 mentioning the version of the UN Regulation, would be as a static reference. He suggested, in reference to slide 6 of GRSG-123-13 that:

“…, device(s) for means of rear visibility or detection as described in UN Regulation No. 158 in its original version, paragraph 1.3., allowing the driver to check the hazard area behind the vehicle, including when towing vehicle(s) of category O,…”.

The expert from the Netherlands agreed with this issue, since UN Regulation No. 158 refers to compliance with the technical requirements and transitional provisions of UN Regulation No. 10, 05 series of amendments. The expert from OICA stated that the above-mentioned device would need to equip even trailers (vehicle category O). GRSG agreed to resume consideration of this issue at its October 2022 session.
