26. The expert from France introduced informal documents GRSP-78-36 and GRSP-78-37 amending working documents ECE/TRANS/WP.29/GRSP/2025/37 and GRSP/2025/38, which aim to correct inconsistencies regarding vehicles of category O. The expert from the Russian Federation asked why a distinction between Rechargeable Electrical Energy Storage Systems (REESS) and batteries used for recuperation only was needed in the regulatory text. The expert from the Kingdom of the Netherlands explained that it was a semantic matter, as by definition a REESS provides electric energy for electrical propulsion and therefore the term does not include batteries used for recuperation only. The experts from France and the Russian Federation worked together to produce a revision of the proposal that would avoid misinterpretations. GRSP adopted informal documents GRSP-78-36-Rev.2 and GRSP-78-37-Rev.2 (as reproduced in annex V) and requested the secretariat to submit them as proposals for supplement 06 to the 03 series of amendments, supplement 03 to the 04 series of amendments and supplement 1 to the 05 series of amendments to UN Regulation No. 100 to the June 2026 sessions of WP.29 and AC.1.

38. The expert from Germany gave a status update on the work of the GRSP Task Force on Automated Vehicles Regulation Screening (TF-AVRS) (informal document GRSP-77-41). Regarding the transport of children, he argued in favour of adding provisions explicitly preventing the transport of unsupervised children by Automated Driving Systems (ADSs). The expert from OICA recalled a resolution on the deployment of highly and fully automated vehicles in road traffic by the Global Forum for Road Traffic Safety (WP.1). On the question of whether to extend the scope of the UN Regulation dealing with crash testing or creating a separate one for category Y vehicles, the experts from Spain and the Netherlands argued in favour of the second option and the expert from Sweden suggested this item be discussed in the task force.

39. The expert from Germany informed GRSP that the task force had already prepared draft amendments to all UN Regulations identified as first priority (Nos. 11, 14, 16, 17, 21, 29, 94, 95, 100, 135, 137, 153, 173 and 174) and two of the UN Regulations identified as second priority (Nos. 127 and 145). The draft amendments are contained in informal documents GRSP-77-57, GRSP-77-58, GRSP-77-59, GRSP-77-60, GRSP-77-61, GRSP-77-62, GRSP-77-63, GRSP-77-64, GRSP-77-65, GRSP-77-66, GRSP-77-67, GRSP-77-68, GRSP-77-69, GRSP-77-70, GRSP-77-71, GRSP-77-72 and GRSP-77-73 . Amendments to UN GTRs are planned in a third step.
