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.

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 para. 1.4. to clarify that recording requirements depend on availability of the trigger or data element itself, amend para. 5.3.1.2. to permit the EDR to write last stop trigger data in volatile memory only, accommodating at least five most recent stops to be overwritten on a first-in first-out basis until any other trigger occurs or the vehicle master control switch is deactivated, and amend paras. 2.5., 2.48. and 2.49. for clarity and consistency with UN Regulation No. 160.

Proposal to:

• Amend para. 1.4. to clarify recording obligations for data elements when sensors lack design capability to meet format requirements,
• Amend para. 2.20. to define engine throttle as driver-requested acceleration torque demand,
• Amend para. 2.73. to define trigger activated,
• Amend para. 5.4.3. to clarify crash test requirements and specify data retrievability after impacts of severity levels set by UN Regulations Nos. 94, 95 or 137,
• Insert new paras. 12.12. through 12.17. establishing transitional provisions with dates from entry into force through 1 September 2035,
• Amend Annex 4 Table 1 to add data elements including occupant size classification, vulnerable road user secondary safety system warning indicator status, and advanced driver distraction warning time since warning issued, with modified recording intervals, sample rates, and ranges for existing data elements.

Proposal to introduce a unified Position Code (X-Y) for all seating positions, add seven new mandatory data elements for driver operation and seat-track position to Annex 4 Table 1, and harmonize ADAS status enumerations into one unified set eliminating fragmented and inconsistent wording across system entries.

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 para. 5.1.3., insert new paras. 5.1.5. and 5.1.5.1. requiring the Approval Authority to refuse type approval unless the Certificate of Compliance for the Cyber Security Management System is issued by the same Approval Authority granting vehicle type approval, while permitting referencing of certificates from other Approval Authorities under specific conditions with documented agreements and clarified responsibilities, and insert new paras. 5.4. and 5.4.1. with equivalent requirements for the Software Update Management System Certificate of Compliance.
