51. The representative of Japan, on behalf of the co-Chair of the IWG on IWVTA, reported on the work progress made in the subgroup for the 1958 Agreement and the subgroup for Regulation No. 0 (WP.29-167-09). He reported that the subgroup for the 1958 Agreement still had to further review the general guideline document, and had considered some editorial issues and clarified the difference between revision and version. He also reported that the subgroup on Regulation 0 had agreed on almost all issues, except for the definition of vehicle type. He informed WP.29 that the subgroup had agreed to conduct a pre-testing of UN Regulation No. 0. He presented a document with questions and answers (WP.29-167-10), which aimed at promoting the understanding of UN Regulation No. 0 and IWVTA among existing and potential Contracting Parties to the 1958 Agreement. He sought the consent of WP.29 to extend the mandate of the IWG on IWVTA by fifteen months, until June 2017 (WP.29-167-11). The World Forum endorsed the extended terms of reference and rules of procedures, and agreed to extend the mandate.
