56. The expert from CLCCR introduced ECE/TRANS/WP.29/GRSG/2022/17 to amend the consolidated Resolution on the Construction of Vehicles (R.E.3) by clarifying the definition of a trailer/semi-trailer in case one or more trailer axles may be driven by a propulsion type integrated into the trailer (e.g. electric engine) in combination with the motor vehicle. The expert from United Kingdom remarked on an inconsistency in the text of the proposal between the contribution to the propelling forces of the vehicle combination at all speeds and the speed limit of 15 km/h. The expert from the Netherlands added that amending R.E.3. and Special Resolution No. 1 (S.R.1) would be just a first step because a number of UN Regulations also need amendment (e.g. UN Regulations Nos. 13, 55 and 100) to allow for the introduction of such semi-trailers and full-trailers.

57. Finally, GRSG agreed to resume discussion on this subject at its October 2022 session on the basis of a revised proposal superseding ECE/TRANS/WP.29/GRSG/2022/17.
