Proposal to require automatic deactivation of AEBS upon activation of an ADS feature and automatic reactivation upon deactivation of an ADS feature.

Proposal to amend the scope to specify that UN R157 would not apply to an ALKS approved as an ADS feature under the forthcoming regulation on Automated Driving Systems.

Proposal to amend ECE/TRANS/WP.29/GRPE/2025/18

Proposal to align the real-driving emissions provisions with the requirements of Euro 7 and to introduce a “levels” concept. An informal document amending this proposal is under development.

Proposal aims to make extendible trailers conform to all lateral protection requirements for trailers regardless of length, in order to remove the safety risk to vulnerable road users when the trailer is in the fully extended position. This is achieved by the removal of section 13.1.1. and 16.1.1 that specify some exemptions to requirements when the trailer is extended.

Proposal to clarify the obligations of the manufacturer to provide information on the location and safe use of emergency exits and fire extinguishers per para. 7.19. of Annex 3.

Proposal to introduce provisions on thermal propagation as a result of a single cell thermal runaway.

Proposal to resolve issues with accepting the approval of M₂, M₃ and N₂ vehicles to R152.

Proposal to cleanse the document with regard to reference to system-initiated manoeuvres to avoid misinterpretation.

Proposal to resolve inconsistency between information required on the communication form of R90 compared to other UN Regulations.

Proposal to ensure that vehicles exhibiting functionality meeting the definition of ACSF-B2 or -E are required to comply with the 01 series of R171 (or later). The 01 series added the necessary technical requirements to ensure the safety of features that allow ‘hands-free’ operation or perform system-initiated manoeuvres.

Proposal to align the wording on “initiation of the powertrain” with MR2.

Proposal to align the text with MR2 for initiation of the power train

Proposals to improve the text related to terminology across propulsion types (e.g., use of term “powertrain”) pursuant to similar improvements agreed via documents WP.20/2025/87 and 90.

Proposals to resolve issues with accepting the approval of M₂, M₃ and N₂ vehicles to Regulation No. 152.

Proposal to ensure that vehicles exhibiting functionality meeting the definition of ACSF-B2 or -E are required to comply with the correct series of R171.

Proposal improve consistency in the bedding/burnishing procedure and to align the Communication Form with that of other UN Regulations.

Proposal to align UN R130 with the harmonised wording approved by WP.29 with regard to conditions for automatic reinstatement of a system at the “initiation of each engine start/run cycle”.

Proposals to resolve issues with accepting the approval of M₂, M₃ and N₂ vehicles to Regulation No. 152.

Proposal to address two gaps identified in the requirements of UNR 155 regarding:

1. Software development and
2. Vehicle with an ADS Feature of Type 2 where vehicle operation is overseen by an organisation responsible for operating the vehicle or fleet of vehicles.

Draft proposal to align the Regulation with the latest regional requirements (e.g., Euro 7) as submitted to GRPE (Informal document GRPE-92-09e).

Proposal to create a new Informal Working Group on harmonized technical regulatory frameworks for Electric Vehicles (EV) / Hydrogen Fuel Cell Vehicles (HFCV) retrofit systems.

Proposal to establish an informal working group to perform a literature review of existing available standards, research, best practice and horizontal regulations relating to the use of artificial intelligence, develop a best practice guidance document for the use and operationalization of artificial intelligence such as machine learning in automotive safety systems, report back to WP.29 with a recommendation for publication of the guidance, and consider the need for further work. Manufacturers present vehicles developed with artificial intelligence features performing safety critical functions. Approval authorities and their technical services lack a frame of reference for auditing such development processes. Horizontal artificial intelligence regulations being developed regionally may not suit automotive sector needs.
