Proposal to amend UN R150-01 addressing three main issues. First, since the GRE-adopted proposal to delete the unique identifier (GRE-92-18) was not part of the March 2026 WP.29 submission, the regulation text requires amendment in the interim, though this may become unnecessary if merged with GRE-92-18. Second, the approval marking approach is aligned with UN R148 by including one example in the body text and referencing other arrangements in Annex 10, allowing deletion of the Table 1 reference and redundant ratio explanations from Figure A10-I. Third, the outdated requirement for function symbols to be placed diametrically opposite the approval number — inherited from UN R3 and R7 but already removed in UN R148 — is deleted from Annex 10, along with a clarifying amendment to the note below Figure A10-I to prevent inconsistent interpretations among technical services. Further details can be found in informal document GRE-94-11.
