12. On behalf of the Chair of IWG on Quiet Road Transport Vehicle UN GTR (QRTV UN GTR), the expert of the United States of America informed GRB about the outcome of a meeting in Baltimore, United States of America, on 30 and 31 May 2018. She pointed out that the objective of the session was to provide a detailed comparison between UN Regulation No. 138 on QRTV, the Federal Motor Vehicle Safety Standard (FMVSS) on Minimum Sound Requirements for Hybrid and Electric Vehicles, as well as of other regional (the European Union) or national (Canada, Japan, the Republic of Korea) regulations in this area. She indicated that the full comparison report would be presented to the November 2018 session of WP.29 with a request to provide guidance on further direction of work. GRB took note of this information and mandated the Chair to request WP.29 and/or AC.3 to extend the mandate of QRTV UN GTR until December 2019.
