54. The representative from OICA introduced GRPE-82-28 presenting differences in definitions between the latest amendment to UN GTR No. 15 and M.R.2. He further outlined different options to solve the issues raised: (a) delete M.R.2 if not maintained; (b) automatically update M.R2 when updating UN Regulations; (c) review and correct inconsistencies on a regular basis; (d) expand to other vehicle categories.

55. The representative from Germany supported the continuous development and maintenance of M.R.2. The Chair recalled M.R.2 was a key issue for the former Chair and he agreed that M.R.2 needed to be kept up-to-date. The representative from EC reminded a decision from the seventy seventh session of GRPE which was left incomplete (ECE/TRANS/WP.29/GRPE/77, para. 55.)

56. GRPE requested the secretariat to submit GRPE-82-28 as a working document including a draft proposal to amend M.R.2 during the next session of GRPE in June 2021.
