Proposal to transfer provisions for electrical safety of trolleybuses from UN Regulation No. 107 (M2 and M3 vehicles) to UN Regulation No. 100 (Electric Power Trained Vehicles). This proposal seeks to clarify the scope of the two Regulations with regard to the electrical safety of trolleybuses.

Proposal to amend the transitional provisions in order to explicitly confirm that approvals granted prior to the respective supplements to the 01 and 02 series of amendments and the establishment of the new guidelines on UN Regulation procedures (documents WP.29/2017/107 including Corrigendum 1 and Addendum 1) will continue to be accepted. This amendment thus confirms the understanding that the new procedures apply only to new approvals and do not affect previous approvals.
