190th WP.29 session (19-22 Jun 2023)

4.8.1. | Proposal for the 13 series of amendments to UN Regulation No. 13 (heavy vehicle braking)

15th GRVA session (23-27 Jan 2023)

8. (a) | Electronic Stability Control

107. The expert from France introduced ECE/TRANS/WP.29/GRVA/2023/2, a proposal to mandate the fitment of an electronic stability function on N₃ concrete mixer trucks with four axles. He highlighted that, given the difficulty to refer to “concrete mixers” in the Regulation, the current proposal was to refer to and include all vehicles with four axles and two power driven rear axles in the scope of the mandatory installation of electronic stability function.

108. GRVA adopted ECE/TRANS/WP.29/GRVA/2023/2, as amended by GRVA-15-56 as draft proposal for the 13 series of amendments to UN Regulation No. 13 (heavy vehicle braking) and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote in June 2023.
