Proposal to introduce provisions for approving single vehicles involved in modular vehicle combinations, e.g. towing trailers, “road trains”.

64. The expert from OICA presented, on behalf of the Chair of the IWG on Modular Vehicle Combinations (MVC), GRVA-05-43, introducing GRVA-05-03 with amendment proposal to UN Regulation No. 13, aimed at allowing the approval of Modular Vehicle Combination with regards to braking. He also presented ways forward for the IWG.

65. GRVA agreed with the proposed ways forward (option 1 noted in the document: “on the basis of an adhoc group meeting of the IWG hosted by the industry”) and encouraged the delegations to send comments to the IWG on (i) GRVA-05-03-Rev.1 and also on (ii) referring to a newer version of the ISO standard in UN Regulation No. 13 (ISO 11992-2:2014).

66. GRVA requested the secretariat to distribute GRVA-05-03-Rev.1 with an official symbol at its September 2020 session, unless a revised document would be submitted by the group.
