Minutes of the 51st Session of Informal Group on IWVTA held June 17, 2026. Proposed UN R0/09 series of amendments (IWVTA-51-03-rev.1) will be submitted to the 199th WP.29 session. Proposed amendments to General Guidelines on transitional provisions separating V.9. and V.9.bis from transitional provisions for XX series and making them independent as P.1. and P.2. applicable to all series will be submitted to WP.29 at its June session. OICA will look for concrete examples of transitional provisions. NL/RDW will submit a proposal on scheme and procedure for adding an attribute in DETA to indicate the latest series of amendments of approvals by the next session.

Provisional agenda for the 52nd session of the IWVTA Informal Group scheduled for November 12, 2026 in Paris. The session will address election of a new Chair, adoption of the agenda and 51st session report, highlights from the 199th WP.29 session, amendments to UN R0 series, contradiction between transitional provisions in UN R22 and Revision 3 of the 1958 Agreement, proposed amendments to Guidelines on Transitional Provisions, IWVTA awareness and promotion, extension of mandates, and DETA scheme implementation.

GRSP sought WP.29 guidance on an apparent contradiction between transitional provisions 15.1.2. and 15.1.3. in the 06 series of amendments to UN R22 (helmets) and article 12.4 of Revision 3 of the 1958 Agreement. WP.29 agreed that the provisions of the 1958 Agreement should prevail over those of specific UN Regulations and that these transitional provisions are invalid, even though the 06 series entered into force on 3 January 2021 after Revision 3 of the 1958 Agreement entered into force on 14 September 2017. Article 12.4 applies to all UN Regulations regardless of date of issuance and preserves each Contracting Party’s freedom to choose whether to accept type approvals issued pursuant to earlier versions.

Document outlining the 1st DETA/IWVTA Workshop held on 17 June 2026 in Flensburg, Germany. The workshop covered presentations on what DETA and IWVTA are, industry and government expectations, and issuance and acceptance of IWVTA certificates in the EU. Survey responses from 15 participants, including from Southeast Asian countries, indicated needs for more explanation on DETA access rights, onboarding processes for new Contracting Parties, and clearer guidance on how IWVTA can be modified to suit individual markets. Suggestions included developing supporting materials and guidelines on IWVTA application procedures and organizing a second workshop in Japan or Asia.

Discussion of R.E.3. revision 8 adopted by WP.29 in November 2025, which allows vehicle manufacturers to apply for new approvals for software versions on registered vehicles. The Netherlands raised concerns about compatibility with type approval principles, the 1958 Agreement, and EU law, citing issues with traceability, multiple approvals for one type, approval requirements for non-production vehicles, and product marking. The document proposes distinguishing between ‘live’ approvals for new vehicles using normal type approval procedures and ‘legacy’ approvals for in-service vehicles using an updated revision concept, with updates to Schedule 3 of the 1958 Agreement and R.E.3. revision 9.
