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.
