Proposal to clarify guidance on reporting maintenance and repair issues by deleting “Such an occurrence is expected to be reported in case of” and inserting “Examples of maintenance or repair issues could include”, adding “safety-critical” before “software”, adding “potential” before “safety”, deleting “implications” and inserting “consequences, or”, deleting “Fitted hardware not compliant to safety performance specifications” and inserting “Not following the repair instructions given by the manufacturer.”

This document proposes guidance on reporting cyber security issues affecting autonomous driving systems safety. The proposal modifies the description of reportable cyber security incidents to replace “Safety-relevant ECU compromised” with “Any cybersecurity threat identified to safety relevant ECU, or” and deletes “ADS control channel manipulated.” The text also clarifies that reporting must align with UN R155 where this Regulation is applied, replacing the reference to “CSMS procedure where R155 is applied.”

Proposal to introduce guidance on reporting the average feature engagement time. The average engagement time is a statistical measure of how long an ADS feature stays engaged per activation, computed as cumulative time divided by number of activations. The average is expected to be computed in an aggregated manner over the whole fleet of vehicles having the same ADS feature, representing the average duration between activations and deactivations of a feature.

Proposal to amend the guidance on reporting safety-relevant communication issues by deleting “Such an occurrence could be reported in case of” and replacing it with “Examples of communication issues could include”, deleting “The remote interaction is unavailable” and replacing it with “Interruption of remote interaction,”, replacing “Information” with “Communication”, adding “the” before “safety threshold”, and adding “(if indicated in the safety case)” after “safety threshold”, and replacing the period after “unavailable” with “, or”.

Proposal to add animals and children to examples of safety-relevant objects in para. 6.1.2.8. The revision inserts “Animals and children (in or adjacent to the roadway, under the vehicle carriage, etc)” into the illustrative and non-exhaustive list of safety-relevant objects. The proposal removes ambiguity for manufacturers developing safety cases and ensures consistent treatment across ADS requirements, making explicit that animals and children are safety-relevant objects even though they cannot be expected to respond predictably based on vehicle signals, traffic rules, or common conventions.

Proposal to add animals and other road users as examples of entities an ADS may encounter in driving situations and test scenarios. The revised text adds “animals, or other road users” to the illustrative example in para. 2.33 and para. 2.34, and replaces “pedestrians” with “these entities” in the corresponding sentence about scenario design. This ensures scenario design used to demonstrate ADS competency explicitly accounts for animal encounters alongside pedestrians and other road users.

Proposal to remove brackets from the ODD paragraph in section 7.3.1.3. The proposal removes square brackets that were included as a result of the ADS-20-46/Rev.3 discussion. The bracketed text addresses scenarios where a new area falls within existing ODD bounds, where deployment in that area might not require ODD modification, and where modifications to the area of operation would not require ODD modification provided conditions and environment in new areas of operation have been considered, but where operation in an area with different traffic laws or behaviour than those for which the ADS’s ability to comply has been demonstrated would require an amendment to the safety case.

Proposal to clarify guidance on reporting of system failures that compromise DDT performance by amending the description of reportable system failures, including modifying language regarding loss of redundancy or reduction in capabilities of ADS features to perform the entire DDT, replacing “failure in an actuator used by the ADS” with “hardware failure that compromises the capability of an ADS feature to perform the entire DDT,” and retaining the existing provision regarding degradation in computational capability.

Proposal to clarify para. 6.1.3.3.2. to specify that the requirement provides an exception for instances where there is a need to move the ADS vehicle before the operational state of its ADS can be verified, remove reference to fallback user since the requirement explicitly refers to ADSF-2, replace “Hand-over to fallback user” with “Allow an appropriate ADS user to take over control”, and clarify that the road safety agent may be permitted to drive the ADS vehicle manually.

Proposal to add an interpretation of the term “other road user” in para. 2.21. of Definitions. The proposal defines “other road user” (ORU) as any entity making use of publicly accessible road infrastructure, covering users making intentional use of roadways with knowledge of traffic rules and other sentient entities that might be found in vehicle paths but cannot be expected to respond predictably based on vehicle signals or traffic rules, such as children and animals. The safety case would address both classes of ORU with appropriate adaptation to account for lower predictability of child and animal behaviours where relevant to the ODD of an ADS feature. The proposal was withdrawn for reconsideration during the further development of GTR 26 and UN Regulation 185.

Proposal to simplify text on AV screening in the GID Introduction section. The revised text condenses the explanation that AV screening amendments to WP.29 Regulations are outside the scope of the GID. The original lengthy paragraph explained WP.29’s screening process, task forces, and technical requirements for systems such as braking, steering, and lighting. The revised text concisely states that WP.29 has updated its regulations concerning aspects of the DDT to enable their application to ADS vehicles, and these AV-related amendments are outside the scope of this document.

Proposal to specify GTR number 26 and UN Regulation number 185 to the Introductory Text.

Proposal to replace “all entirely” with “solely” in the Introduction.

Proposal to delete the final sentence of the Introductory Text of the GID, which states “Nonetheless, the amendments to these other regulations, including those that enable performance of the DDT, are outside the scope of the ADS regulations and of this document.” The deletion removes redundant language already conveyed in the preceding text that modifications of other regulations related to ADS are outside the scope of this document.

Proposal to clarify in the introductory text that the document does not limit requirements or introduce new requirements, update the reference to WP.29 adoption of the Regulations under the 1958 and 1998 Agreements, and add explanation that interpretation examples are not exhaustive, definitive, or compulsory and that each safety case must be tailored to the characteristics of the automated driving system, its features, their operational design domain, and assessed on its own merits.

Proposal to delete text from the draft Introduction section of the Guidance and Interpretation Document on ADS Regulation. The formal submission to GRVA produced in June was based on the Workshop information document that contained additional explanations on the status of work. These contents are not appropriate for the final version of the Guidance and Interpretation Document.

Proposal to add a bullet citing Automated Vehicle Safety Consortium (AVSC) Best Practice for ADS Remote Assistance Use Case (Nov. 27, 2023), available at https://avsc.sae-itc.com/publication/avsc-04-2023, which provides detailed explanation of different discrete functions underneath the broader remote operations heading, divided into interactions with vehicles or a fleet of vehicles and interactions with humans, with each then divided into more specific types of functions.

Proposal to delete the interpretation in para. 7.2.1.9.1. The Testing sub-group decided not to provide additional guidance regarding approaches for criticality. The topic is already covered in the Guidelines and Recommendations for ADS Safety (WP.29/2024/39). Several options were proposed but none achieved consensus, and potential compromise solutions did not provide a worthwhile addition on top of existing guidance already available in WP.29/2024/39.

The proposal revises para. 7.2.1.4.1. to replace the original text on personnel competencies with revised text that focuses on demonstrating confidence in personnel competence to support appropriate use of simulation results rather than prescribing specific qualifications, role profiles, or individual assessment criteria. Documentation may be supported through organisational or system-level arrangements including defining responsibilities, identifying knowledge and skills needed, providing training and supervision, maintaining records of experience and qualifications, and providing evidence of accreditations and management systems.

Proposal to modify the explanation on performance issues constituting an unreasonable risk to safety by specifying that this occurrence should be understood as deviations, degradations, or performance limitations shown by an ADS feature that affect its ability to perform the DDT within the declared ODD, triggered by events that present an unreasonable risk to safety and/or are beyond expected variability or acceptable degradation, replace “may” with “might” in references to discrete failures and risk existence, replace “Violation of” with “Non-compliance with respect to the”, delete references to identified reduction in safety margins and exceeding overall hazard exposure thresholds, replace “the rate of hazardous event occurrences” with “hazardous event exposure:”, and replace “suggests” with “could suggest”.

Proposal to add examples to the guidance on reporting noncompliance with DDT performance requirements under para. 6, specifying that failures include systematic or repeated deviations from DDT performance requirements defined under para. 6, non-compliance with respect to DDT performance requirements and requirements on interactions between the ADS and its user or other requirements under para. 6, and deviation from Remote Interaction/Intervention as described in the Safety case, with a note that some examples can reveal unreasonable risk to safety requiring only a single report noting this aspect.

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.

The UN IWG on Cyber Security and OTA held its 38th session 29 June–1 July 2026 in London with remote participation. The group adopted the provisional agenda and minutes from the 37th session. Three items from the IWG were presented at the May GRVA meeting: multistage vehicle documents to become working documents for September; RXWIN documents with elements in square brackets to be resolved; and SUMs document returned for further discussion. For R155, the group agreed to forward multistage amendment proposals as working documents to September GRVA. The UK proposal on STU and component approval for R155 was discussed extensively; the UK will draft a proposal for components only. The UK proposal on remote operation for ADS requires further development. The group will review ADS GTR cyber and software provisions. RXWIN proposal documents were adapted; R155 was removed and R89 and R156 sections amended; reviewers may address concerns by 31 July 2026. Germany’s proposal requiring the same Type-Approval Authority for CSMS and vehicle type approval was discussed; a dedicated meeting will be scheduled. The UK proposal on approvals for out-of-scope vehicle types was introduced. Draft Terms of Reference were revised and will be forwarded to GRVA for September approval. The next meeting is scheduled for 3 September 2026, 12:00–15:00 CET.

GRVA reviewed the advance copy of ECE/TRANS/WP.29/2026/137 circulated in April 2026 and proposed modifications integrated in the final version in June 2026. The amendments replace [ADS], [This Regulation], [XXX], and [number of this Regulation] with [185]; amend Contents, paragraph references, and numbered paragraphs; add periods and remove brackets; renumber paragraphs 1.4.11.5, 1.4.11.5.1., and 1.4.11.5.2. as 1.4.12., 1.4.12.1., and 1.4.12.2.; replace square brackets with parentheses and examples in tables; and amend fallback requirements and data recording specifications.

Proposal to establish uniform provisions for the approval of motor vehicles with regard to their Automated Driving Systems, covering vehicles of categories M₁–M₃, N₁–N₃, L₆ and L₇.
