Proposal to amend UN R153 to account for vehicles of category X and Y equipped with an Automated Driving System. The Regulation, originally drafted for vehicles with driver and manual driving controls, is extended to vehicles without driver and without manual driving controls inside the vehicle. Provisions related to driver and manual driving controls shall not apply if not already covered by this amendment. In manual driving mode, no special provisions apply. In a mode where an ADS feature is active, relevant ADS requirements apply.
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.
42. GRSP noted that at its November 2025 session, WP.29 reaffirmed its objective to adopt all documents related to the review of existing UN Regulations related to Automated Driving Systems (ADS) at its June 2026 session and invited the Chairs of the Working Parties to consider various strategies to ensure timely preparation of the required documents. This corresponded to option 1 in informal document WP.29-197-25 and would require all proposals under this agenda item to be adopted by GRSP on this session.
43. Following a general update by the expert from Germany on the first day of the meeting, the GRSP Task Force on Automated Vehicles Regulation Screening (TF-AVRS) continued work on the margins of the meeting to refine the proposals and submitted a number of informal documents to amend the proposals in working documents under this agenda item. GRSP adopted the following proposals :
