Explanation of a “first set” of guidelines prepared by the WP.29 secretariat concerning the submission and adoption of modifications to UN Regulations, especially taking into consideration the pending Revision 3 to the 1958 Agreement which envisions, among other things, the acceptance to multiple “versions” of each regulation. This document covers: amendments resulting from draft Revision 3; publication of new series of amendments; long transitional provisions; versions of UN Regulations; use of cross-references; amendment commencement dates; consolidation of amendments to once per year; and use of “compilations” of modifications.

Proposal to amend the draft agreement to address situations where a Contracting Party disagrees with an adopted amendment and ceases to apply a given UN Regulation. The proposal seeks to clarify that the Contracting Party would still be obligated to accept type approvals based on the previous versions of the regulation (i.e., approvals based on versions of the regulation that the CP had been accepting before the amendment) for one year following its notification to cease application of the regulation.
