52. The expert from OICA introduced documents GRSG-122-10 and GRSG-122-15, proposal for Supplement 3 to the 03 series of amendments of UN Regulation No. 34 and Proposal to amend document ECE/TRANS/WP.29/GRSG/2021/19 which is a Proposal for a new 04 series of amendments of UN Regulation No. 34.

53. The expert from France recalled that para. 9.3. of UN Regulation No. 34 is not yet transposed in the UN Regulation No. 153. He therefore suggested joint activity on this proposal with GRSP to ensure alignment between the GTRs and UN Regulations. The Expert from the Russian Federation suggested a postponement of the revision of the documents GRSG-122-10 and GRSG-122-15 because the Russian Federation currently does not apply UN Regulation No. 153 and will need time to review these documents.

54. Following a detailed technical discussion from the experts from France, the Russian Federation, The European Commission and OICA with regarding the paragraph that is yet to be transposed in the UN Regulation No. 153, GRSG suggested document GRSG-122-10 be converted into an official document for reconsideration in the 123rd session of GRSG in March 2022. GRSG also suggested current document ECE/TRANS/WP.29/GRSG/2021/19 be reviewed and submitted for reconsideration at the 123rd session of GRSG as official document ECE/TRANS/WP.29/GRSG/2021/19/Rev.1.
