GRVA will continue to establish and maintain the United Nations regulatory framework for Automated Driving Systems, including UN R185 and GTR 26. GRVA will continue its work on cyber security, over-the-air software updates, and the Data Storage System for Automated Driving. GRVA will focus on implementation of ADS and development of provisions for the Exchange of Scenario-Relevant Information. GRVA will further elaborate requirements for Advanced Driver Assistance Systems, building on UN R79 and UN R171, and for Automated Emergency Braking Systems, building on UN R131 and UN R152.

Consolidated revision of the working document on guidance and interpretation document for GTR 26 and UN R185 on Automated Driving Systems (GRVA/2026/24). The document facilitates interpretation of ADS requirements when applied to particular ADS vehicles, provides guidance on evidence for requirements, and helps harmonize application across manufacturers and authorities. It addresses definitions, application for approval, approval procedures, ADS performance of the Dynamic Driving Task in nominal, critical, and failure situations, interactions between ADS and users, safety management systems, test environments, safety cases, and post-deployment safety monitoring.

Proposal to amend paragraph AI to introduce a link between existing text in Part A and new text in Part C regarding vehicle transformations, and insert new Part C providing guidance for the application of UN Regulation No. 155 to transformed vehicles. The proposal adds section 6 clarifying that the requirement for the Certificate of Compliance and type approval to be issued by the same Approval Authority applies only within the scope of the type approval granted to the manufacturer concerned, and does not restrict another manufacturer from obtaining a separate type approval and associated Certificate of Compliance from the responsible Approval Authority.

Proposal to amend GRVA/2026/34 proposing to amend para. 5.6.1.2.7. to modify the specified maximum RCP operating range from 6 m to 10 m, with provision to extend to a maximum of 15 m if direct line of sight between the remote-control device and the vehicle is ensured. The justification notes that RCP systems with extended ranges are already offered in large markets without regulatory limits, that radio wave-based ranging requires safety margins reducing effective usable range, and that increased range would reduce blind areas behind vehicles and allow drivers to better monitor surroundings while manoeuvring, reducing risks and increasing overall safety.

Proposal to amend Annex 8, paragraph 2.8. to establish performance-based requirements ensuring continuous trailer immobilisation during service brake pressure depletion. The amendment requires that when a trailer is uncoupled and the park brake control is released, braking forces from combined service and parking braking systems shall hold the laden trailer at any time when service brake energy reservoir reduces from 850 kPa to 0 kPa, and that adequate overlap between service brake and spring brake functions be ensured so no loss of holding capability occurs during pressure depletion.
