Guidance request on restraint system with airbag submitted by Kingdom of the Netherlands. Question whether a restraint system approved according to UN R16 shall bear the word AIRBAG in the approval mark when an airbag is part of the restraint system. The Regulation seems not to require it. Discussion whether it is desirable and whether the Regulation must be updated. Proposal to amend the Regulation to include AIRBAG in the approval mark in case an airbag is part of a restraint system. Alternatively, it could be decided to leave the situation as is and see the addition of AIRBAG as optional.

This document raises concerns regarding identification of child restraint systems through type approval numbers. Multiple brand names are marketed under single type approval numbers, creating market confusion and hampering consumer choice. Products with identical type approval numbers but variations in plastic parts have been identified and failed frontal impact testing. Proposed measures include limiting brand names per type approval number to five maximum, adding manufacturer names to type approval labels, and establishing a publicly accessible database of type approval information.

IWG CLIV Phase 2 addresses development of a UN Regulation for buses and coaches. The 13th through 17th sessions, held between virtual and in-person meetings from March to May 2026, focused on drafting the bus UN Regulation, refining text on scope, definitions, visual signals, and transitional provisions. Feedback from GRE and GRSG identified scope clarity issues and potential amendments to UN R48. Formal submission of a UN Regulation for buses is anticipated at the 80th GRSP session, with feedback requested before 10 June 2026, and subsequent drafting of a UN Regulation for light vehicles is planned to commence in the second half of 2026.

This document presents generic images of various door handle designs, including door handles in door pockets, button type door handles, electric push buttons, electric touch type door handles, and flush buttons.

The document presents an update on the amendment of GTR No. 20 concerning new requirements on thermal propagation. CPs/sponsors agreed to delete para. 265, which was considered redundant in view of paras. 263 and 264. The amendment addresses flammability, toxicity, and corrosiveness of vented gas, with final endorsement by GRSP expected in June 2026 and adoption by WP.29 in November 2026.

Proposal to amend para. 9.(a) to clarify expansion of the protection scope of electrical and battery safety, including thermal propagation in cases of V2X, parking, and charging. The modification addresses new vehicle functionalities like V2X, defined in UN GTR No. 22, where traction batteries cover external power and energy demand. Additional requirements must be added, including isolation resistance requirements for coupling systems for charging the REESS, as defined in para. 5.1.1.2.4.4. of UN GTR No. 20.

Proposal to amend para. 2.1. to define “appropriate adaptor” as specified by the CHSS manufacturer and clarify container valve and end plug components, amend paras. 5.1.1., 5.1.2., 5.2., 9.2.1., 9.2.3.2. and Annex 3 para. 2.1. to specify that connections between supply lines for additional TPRDs and appropriate adaptors meet test requirements and are within scope, delete “hydraulic” in para. 9.2.1. to permit gas as test option, and amend Annex 3 para. 5.1. to remove reference to appropriate adaptors for fire testing.

Proposal to insert a new para. 5.1. requiring that features for design or aerodynamics in the head impact zone shall not impose an additional cause of danger to pedestrians and other vulnerable road users and shall not exhibit openings or contain materials that may increase the risk or seriousness of injury, and renumber paragraphs 5.1. to 5.2. as paragraphs 5.2. to 5.3. This aims to maintain pedestrian safety as requirements become mandatory for small-series vehicles according to Commission Delegated Regulation (EU) 2022/2236 from 7 January 2026, addressing hazards from openings in the head impact zone that may trap impacted heads or permit head intrusion and from bonnet materials like plastics that may deform or fracture, creating injury risks not currently addressed by UN R127’s component tests.

Australia proposes examining the case to bring UN R95 in line with Euro NCAP by establishing an ad-hoc group of interested experts to consider a more representative test barrier and dummy, allow flexibility to update Euro NCAP protocols, further consider alternative or additional equitable dummy choice and addition of a near-side rear occupant to UN R95, and examine more advanced barriers with improved dummy bio-fidelity and alternative injury assessment.

The Informal Working Group on Emergency Door Opening (IWG-EDO) will develop amendments to UN Regulations Nos. 11 and 21 and request authorization to amend UN GTR No. 1 and UN GTR No. 14, with a draft for submission to GRSP’s 80th session. In a second step, it will develop amendments for further post-crash extrication requirements for UN Regulations Nos. 94, 95, 135 and 137 and UN GTR No. 1 and 14, with a draft for submission to GRSP’s 82nd session. The group will be chaired by Germany with the Republic of Korea as Vice-Chair and OICA providing the Secretariat.

The IWG EqOP held its 16th meeting on May 18, 2026, with 40 online participants from Contracting Parties and Industry. The agenda and minutes of the 15th meeting were approved. Three Task Forces—Rear-end assessment, Virtual crash testing, and Frontal impact and restraint systems—are operational with meetings planned in June 2026. A preliminary report to GRSP 79th session was presented and revised. Upcoming meetings include TF3 on June 11, TF4 on June 25, and TF2 on June 29-30. Each Task Force is invited to structure identified topics by prioritizing them and assigning short, medium, and long-term horizons, and to map contributions within the Task Force.

The agenda includes a workshop with two sessions addressing whether UNR17 dynamic testing should be mandatory and updates on ongoing research including CNCAP, Euro NCAP, EvaRID, BioRID, parametric study, and SET, discussion of a potential in-real-life workshop in October at BASt, and determination of the next meeting date.

The Working Party on Passive Safety discussed a proposal to delete transitional provisions 15.1.2. and 15.1.3. from UN R22 on the basis that they contradicted article 12.4. of revision 3 of the 1958 Agreement. GRSP concluded that in case of contradiction between the provisions of Revision 3 of the 1958 Agreement and those of UN R22, the provisions of the 1958 Agreement should prevail. This interpretation matter is being brought to the attention of WP.29 because it may affect other UN Regulations with similar provisions under the purview of other subsidiary working parties. GRSP requested guidance on the correct interpretation of transitional provisions 15.1.2. and 15.1.3.

The agenda includes a wrap up of EDO discussion during the 79th session of GRSP, authorization to amend GTR 1 and 14, transformation of the task force into an IWG, submission of working documents on amendments to UN R11 including Korea proposal about intuitiveness images and German proposal about amendments to UN R100, any other homework of 5th EDO meeting, amendments to UN R21, reflection on comments during 79th session of GRSP, remaining homework for 6th EDO meeting in Paris, and next meetings.

Homework item #15 on definition of emergency events was reviewed. The Task Force differentiated between life events and emergency events, with only the latter within scope. Discussion addressed whether UN R100’s event definition might be too restrictive and whether auto door lock functions and triggers require further definition. Para. 6.4.3 wording to enter or depart the vehicle even after a power loss was noted as addressing concerns. The trigger in UN R100 should be used; other triggers may be considered based on proposals. A proposal concerning UN R100 will be uploaded to the Wiki. Amendments to GTR 1 are expected for submission to GRSP in December, with the Republic of Korea, United States of America, and Canada to provide a first draft for the September meeting. Authorization request and Terms of Reference will be submitted to WP.29 at its November session. Participants are requested to provide comments on informal documents and suggested solutions for identified issues.

The 17th session of the Children Left in Vehicles informal working group met online on 28 May 2026 to finalise the draft UN Regulation for buses and coaches for presentation at the 79th GRSP session in June. The group agreed to retain the title and scope structure, remove Automated Driving System from definitions, retain Vehicle Master Control Switch wording, include Special Purpose Vehicles, remove the first sentence of paragraph 5.1, replace SOS Morse code signalling requirements with existing hazard warning lights combined with the horn, remove optional requirements from paragraph 5.4.4.6, remove Figure 2 and paragraphs 6.3.7 to 6.4.2, remove Section 11 Transitional Provisions, and remove Annex 2.

The agenda includes feedback from the June GRSP session on the submitted draft UN Regulation, next progression of work for light vehicle drafting and consideration of a September face-to-face meeting.

UN IWG CLIV presented a draft UN R regulation proposal for buses at May UN GRSP session covering physical inspection system with no sensing required. Discussions on light vehicle regulation, paused since early 2026, can now resume. Light vehicles will have sensing related performance requirements. ISO CPD surrogates availability will be crucial to implement the regulation. UN IWG CLIV will hold a 4-day workshop from 08–11 September, likely at UTAC/France, focusing on light vehicles, welcoming ISO CPD expert participation and presentations on ISO CPD status and test tools.

The 18th session of the Children Left in Vehicles Informal Working Group convened online on 25 June 2026. Feedback from GRSP on the draft UN Regulation for buses and coaches was positive, with a 10 July submission deadline for further comments. Australia will circulate a preliminary draft UN Regulation for light vehicles to Vice-Chairs before the September face-to-face meeting in Paris. The bus UN Regulation will initially include only Physical Inspection Systems, while light vehicle discussions will address indirect, indirect-plus, or direct sensing systems. A trilateral meeting between Australia, the United States, and Canada made constructive progress on Global Technical Regulation development, with potential for a November WP.29 vote.

A new UN Regulation is being drafted for N₁vehicles of category Y (vehicles equipped with an automated driving system, not capable of manual driving exceeding 6 km/h, and not designed to carry occupants). The draft incorporates crash safety requirements from UN R94, UN R95, UN R137, and UN R153. Draft version 5 adds provisions for simplified approval procedures for previously approved vehicles, references UN R137 for vehicles between 2,500 and 3,500 kg, and clarifies B pillar references. Open issues include confirming non-applicability of lateral collision partial tests and clarifying which simplified procedures are permitted.

Minutes of the 26th meeting of GRSP TF on AVRS held on Tuesday 22nd of May 2026 online. The agenda and previous minutes were approved. Status reports were received from other groups, with a closing meeting on ADS fitness expected in June. GRSP reviewed consistency of ADS fitness work and UN Regulation 137 sensor updates. EC presented updates on UN Regulation N₁Y and UN Regulation 127 pedestrian protection. OICA raised discussion on frontal test procedures in Annex 3 referencing UN Regulation No. 94 for vehicles with maximum mass not exceeding 2,500 kg and UN Regulation No. 137 for vehicles with maximum mass exceeding 2,500 kg and not exceeding 3,500 kg. No comments were received on passive safety requirements for ADS steering systems. Future meetings are scheduled for 1–5 June, 1st July, 4th September, 5th October, 27th November, 1st December, and 7–11 December.
