Proposal to consolidate speed and distance requirements under the requirement to adapt driving behaviour to conditions.

Proposal to clarify that ADS Off means the ADS is prevented from performing any activity, and ADS On means the ADS has been requested to perform activity, either an ADS feature is performing the DDT or the system is in ADS Standby, to distinguish ADS Off from ADS Standby and be consistent with off mode definition in UN R171.

Proposal to amend Figure 1 in para. 4.2.2.2.3 to add an (ADS feature) Available box within the ADS Standby box. The (ADS feature) Available state shows that no ADS feature is performing the DDT, however the ADS may be performing some other activity such as determining whether the vehicle is in the ODD. The figure depicts ADS Off, ADS Standby, ADS Feature (A) Active, ADS Feature (B) Active states with transitions for Activation, Deactivation, Switching On, and Switching Off.

The change request seeks to amend the road-safety agent Instructions explanation to indicate that examples regarding road safety agent instructions to the ADS vehicle are territory-based. The revision adds the phrase “which depending on the country of operation” to both the list of example instructions and the statement regarding communication methods, clarifying that instructions from road safety agents vary from country to country.

This change request proposes to amend the explanatory text for para. 6.1.2.11. (UNR)/4.1.2.11. (GTR) by modifying the phrase “the ADS is always responsible for detecting them” to “the ADS is always responsible for detecting and responding to them” and by deleting two “remote intervention” examples of non-ADS strategies. The rationale states that the ADS is responsible for both detection and response to instructions from road safety agents, and that remote intervention examples should be avoided at the current stage as this topic is already under discussion in Phase Two.

Proposal to amend para. 6.1.2.5 (UNR)/4.1.2.5 (GTR) to clarify that the ADS is always responsible for detecting and responding to priority vehicles, and to delete the examples of non-ADS strategies involving remote intervention.

The revised text adds ISO 21448, GB/T 34590 Road vehicles-Functional safety, and GB/T 43267 Road vehicles – Safety of the intended functionality to the original reference standards ISO 26262-2/8:2028 and ISO 9001 2015. GB/T 34590 is an important reference for functional safety in China and ISO 21448 and GB/T 43267 are important references for SOTIF.

Proposal to correct a paragraph number error in para. 5.3.2.15 of the GTR and para. 7.3.2.15 of the UNR by renumbering them as 5.3.2.14 and 7.3.2.14 respectively. The safety concept shall describe the manufacturer’s approach to scenario selection to cover the reasonably foreseeable situations and conditions that the ADS will encounter including how the following aspects are covered, aligned with WP.29/2026/139 (GTR) and WP.29/2026/137 (UNR).

Proposal to delete example “collision” under “Failure to meet the ADS requirements under paragraph 6 of this Regulation” in Annex 1 (GTR) and 3 (UNR) List of reportable occurrences by reporting type. The rationale states that not all collisions involving ADS vehicles constitute failure to meet ADS requirements, as some collisions are not caused by ADS or the ADS vehicle, and some collisions are not avoidable, such as suddenly appearing obstructing road users.
