Proposal to amend the General Guidelines for United Nations regulatory procedures and transitional provisions in UN Regulations based on WP.29/2024/76, to move transitional provisions applicable to all series of amendments to the beginning of transitional provisions sections, retitle successive series provisions as “Transitional provisions for the XX Series” and “Transitional provisions for the XX+1 Series”, add footnote reference 6 to para. V.3, and correct terminology from “previous” to “preceding” in footnotes 4–6 for consistency.

The Informal Working Group on International Whole Vehicle Type Approval assists WP.29 in harmonizing vehicle regulations under the 1958 Agreement. It clarifies issues related to UN Regulation No.0 and General Guidelines on Transitional provisions, upgrades UN Regulations applicable to IWVTA annually, and submits amendment proposals to WP.29 each November. Short to mid-term objectives include proposing user-friendly U-IWVTA and packaged L-IWVTA by end of 2029. Long-term objectives involve submitting proposals for full IWVTA covering all necessary UN Regulations. The group operates under WP.29 supervision, is open to 1958 Agreement Contracting Parties and NGOs, and makes decisions by consensus.
