94. The expert from France updated GRVA on the development of their proposal in ECE/TRANS/WP29/GRVA/2022/14, aimed at requiring that concrete mixer truck be fitted with a vehicle stability function. He had discussed the proposal with the expert from OICA in order to identify which vehicle configuration would be relevant. The expert from OICA explained that vehicle manufactures do not produce concrete mixer trucks and that most of the concrete mixers were built on the basis of 8×4 or 8×4/4 chassis, and only very few were 8×2 vehicles. The expert from Switzerland identified that many concrete mixer trucks were vehicles of Category G, with significant roll over risk.
95. GRVA agreed to keep GRVA-13-23, GRVA-13-39 and GRVA-14-27 on electronic stability control on the agenda for its next session.

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.
