Proposal to amend para. 5.3.2. to require notification of assessment methods and criteria including paras. 8.2. and 8.3., insert new paras. 8.2. and 8.3. establishing criteria for equipment installation without further assessment, and amend Annex 1 to require disclosure of equipment excluded from assessment pursuant to paras. 8.2. and 8.3. The amendments clarify that equipment with negligible intrinsic cyber security risk installed according to manufacturer specifications and not introducing cyber security risk, and standard non-automotive equipment connected solely for power supply with no increased cyber security risk, shall not invalidate approval of the original vehicle type under UN Regulation No. 155.
Proposal to insert a new sub-paragraph 5.6.1.1.4.1 to establish exemptions for Automatically Commanded Steering Function Category A functions designed for off-road low-speed vehicle recovery manoeuvres, and amend para. 5.6.1.2.7 to increase the specified maximum Remote-Control Parking operating range from 6 m to 15 m.
Proposal to amend UN R155 by inserting new para. 5.1.3.(e) establishing that the Certificate of Compliance for the Cyber Security Management System shall not be issued by a different Approval Authority than the one granting type approval, and amend UN R156 by inserting new para. 5.4. establishing that Approval Authorities shall not grant type approval if the Certificate of Compliance for the Software Update Management System has not been issued by the same Approval Authority granting type approval. Justification includes ensuring holistic cybersecurity assessment, clarifying reporting obligations under para. 7.2.2.2.(g), addressing unharmonized mutual recognition of management system certificates, maintaining consistency between regulations, and upholding the fundamental principle that approval authorities retain responsibility for all aspects of type approval.
Proposal to amend para. 2.14. to insert a footnote clarifying that the road surface friction coefficient of 1 for sufficient nominal Peak Braking Coefficient (PBC) is understood to be a minimum value. This document is based on working document GRVA/2026/21 as amended by informal document GRVA-25-36.
Proposal based on informal document GRVA-25-43 to amend Annex 4, para. 3.5.1. to require the manufacturer to demonstrate to the Type Approval Authority at least every three years that the safety management system continues to comply with requirements for software and hardware employed in the system. This amendment applies the same principle regarding Safety Management System compliance as specified in UN Regulation No. 171 on Driver Control Assistance Systems.
Proposal to establish a Guidance and Interpretation document supporting implementation of the proposed UN Global Technical Regulation and UN Regulation on Automated Driving Systems. The document, based on informal document GRVA-25-20 reviewed at GRVA’s twenty-fifth session, provides draft guidance as of the seventeenth GRVA Workshop on ADS (27 April–1 May 2026), with restructuring and refinement expected for submission to GRVA at its twenty-sixth session (14–18 September 2026), to facilitate interpretation of ADS requirements, provide evidence guidance, and harmonize application across manufacturers, authorities, and inspection bodies.
