33. The expert from the United Kingdom of Great Britain and Northern Ireland presented GRVA-14-42 on behalf of the Special Interest Group on UN Regulation No. 157 (ALKS). He recalled recent achievements and informed that the 01 series of amendments to UN Regulation No. 157 was expected to enter into force within the next six months. He explained that the group worked on clarifications to the DSSAD requirements in ECE/TRANS/WP.29/GRVA/2022/16, which was proposed to be adopted as Supplement 1 to the 01 series of amendments to UN Regulation No. 157. He reported on discussions within the group concerning the drafting of an interpretation document, the improvement of the information document, and the review of the restriction of regular lane change to Category M1 and N1. He suggested that GRVA discuss these future actions.

34. The expert from OICA suggested that the group should work on an interpretation document, only if there was an identified need and stated that deciding on such a work item was premature. The expert from France suggested that, if any provision in the regulation required clarifications, then this should first be achieved by a supplement to that regulation. The expert from the Netherlands agreed with France and added that experience should be gathered first before engaging in such activities. The expert from Japan supported the views of OICA.

35. The expert from Germany stated that, from the perspective of a Technical Service, similar practices to those of the Technical Services Group (TSG) under the Working Party on Passive Safety (GRSP) could be envisaged. GRVA expressed words of cautions to not create a parallel universe in the regulatory world and agreed that any potential lack of clarity should be addressed via a supplement.

36. The expert from the United Kingdom of Great Britain and Northern Ireland introduced ECE/TRANS/WP.29/GRVA/2022/16 (as amended by GRVA-14-43), developed with the guidance of the leadership of the IWG on EDR/DSSAD and aimed at resolving open questions related to the data element recording by DSSAD in UN Regulation No. 157.

37. GRVA adopted ECE/TRANS/WP.29/GRVA/2022/16, as amended by GRVA-14-43 and requested the secretariat to submit it, as a supplement to the 01 series of amendments to UN Regulation No. 157, to WP.29 and AC.1 for consideration and vote at their March 2023 sessions.
