Proposal to provide guidance for interpretation of “Type of REESS” (Rechargeable Electrical Energy Storage System) as defined in UN R100 para. 2.48. The document establishes that differences in REESS should be evaluated from the perspective of substantial impact on safety performance. It describes key elements for assessing impact on safety within each essential aspect: manufacturer responsibility, cell chemistry/capacity/physical dimensions, cell number/connection/support, casing construction/materials/dimensions, and ancillary devices. The guidance provides examples of changes not causing or potentially causing significant differences, including production location changes, multi-sourcing of cells, and process improvements.

The CLIV IWG held its 16th online session on 23 April 2026. The group discussed amending the SOS Morse code definition to clarify it as a continuous sequence of three dots, three dashes, and three dots. Delegates agreed the scope for M₂ and M₃ category vehicles requires clearer definition to exclude camper vans and caravans and limit application to vehicles designed or equipped primarily for child carriage. Homework tasks include reviewing UN Regulation definitions for vehicle master control switches, proposing wording for operational isolation of physical inspection systems, and researching paragraph 5.4.4.6.2. The September in-person meeting location remains under consideration, with Paris confirmed as a possible option pending final decision by end of July.

The 5th Emergency Door Opening Task Force meeting was held 21–23 April 2026 in Seoul. The meeting minutes of the 4th EDO meeting were adopted without amendment. A report concerning the TF EDO work programme was delivered to WP.29 AC.2 and AC.3 during the 198th session of WP.29, with informal endorsement to transform the Task Force into an Informal Working Group. Discussions addressed amendments to UN Regulation No. 11 and No. 21, including test procedures for power loss, interior and exterior door opening, intuitiveness, and backup systems. Documents EDO-05-03, EDO-05-04, EDO-05-05, EDO-05-07, EDO-05-08, EDO-05-09, and EDO-05-12 were reviewed. Multiple homework items were assigned for completion before the 6th EDO meeting scheduled for 1–3 September 2026 in Paris.

Proposal to insert new paragraphs 0.2. and 0.2.1. to clarify the assessment procedure for door opening and permit the use of an external vehicle lift to return a vehicle to its wheels following the side impact test for workshop health and safety compliance, and insert new para. 5.3.3.1.1. to specify that if necessary the vehicle shall be put back on its wheels and paragraphs 5.3.3. and 5.3.3.1. shall apply once in this condition.

Italy opposes GRSP-79-05 proposal to delete paragraphs 15.1.2 and 15.1.3 of transitional provisions, which would permit production and marketing of helmets to the earlier 05 series of amendments to UN R22. Italy argues restoring approval for UN R22.05 helmets would set technical requirements back 26 years, disrupt markets with obsolete products, penalize companies investing in UN R22.06 adaptation, and frustrate safety improvements. No appreciable price difference exists between UN R22.05 and UN R22.06 helmets, negating cost justification.

The Equitable Occupant Protection informal working group pursues equitable and enhanced protection of diverse populations through robust, inclusive regulatory solutions addressing rear-end impact soft tissue neck injuries and frontal impact restraint systems. The group extends assessment towards brain injuries, soft tissue neck injuries, and lower extremity injuries with high frequency and risk of permanent medical impairment. Four task forces focus on rear impact seat assessment, virtual crash testing, frontal impact and restraint system requirements, and assessment of currently not considered injury types. Workshops are scheduled for June 29-30 on rear impact assessment, September 7 in Munich on virtual crash testing, and November 4-6 in Tokyo on frontal impact.

Proposal to insert a new paragraph 0.4. explaining that the second level warning of safety-belt reminders is intended to warn if one safety-belt is unfastened during normal driving conditions as specified in paragraph 5.2.4.1., and that other safety warnings may alert the driver to check overall safety of occupants and stop the vehicle, with the second level warning discontinued per paragraphs 5.2.4.3.(a) to (c)©, and amend paragraph 5.2.4.3. to add a new subparagraph (d) allowing discontinuation of the audible signal when other audible safety warnings are triggered in circumstances of imminent danger where the vehicle has to be stopped.

This document presents VDA 812-001 (05/2026), a recommendation for qualification of pyrotechnics and inflators for automotive restraint applications. The recommendation combines a Propellant Information Package and inflator ageing procedures. Propellant must demonstrate robustness against thermal stimulus of 107°C for 408h or 90°C for 1000h and moisture stimulus, with mechanical stability, density, and burn rate criteria assessed before and after ageing cycles. Inflator evaluation addresses structural safety, functional safety, effluents, performance characterization, and environmental simulation, including high temperature oven testing, accelerated heat ageing, and sequential environmental testing to ensure suitability for restraint systems.

The document also proposes guidance on REESS type definition.

This document reports on online meeting in April 2025 that discussed the Safe System approach, Vision Zero principle, cost-benefit considerations, seat belt use, impact energy, bus front deformation, and scope of Regulations No. 93 and No. 29. A Norwegian Safety Investigation Authority report examined 55 head-on collisions involving buses from 2012–2025, finding that full-frontal collisions often had survivable outcomes, while corner-to-corner collisions frequently resulted in fatal accidents. The investigation identified that current front protection is inadequate in low-overlap collisions. The task force will work on terms of reference and scope, invite more contracting parties, and organize an in-person meeting in Norway.

Proposal to establish uniform provisions concerning the approval of M₂ and M₃ vehicles to assist in the prevention of children being left inside. This regulation applies to vehicles of categories M₂ and M₃ class B and III designed or equipped primarily for the carriage of children, or special purpose vehicles of categories M₂ and M₃ class B and III designed specifically for the carriage of children. Vehicles shall be equipped with a physical inspection system which satisfies the requirements, including that the system shall be engaged when the vehicle master control switch is turned off and shall generate an external visual and audible warning if not disarmed within three minutes for buses not exceeding 22 passenger seats, or within five minutes for buses exceeding 22 passenger seats. The audible warning shall be greater than 60 dB(A).

TF-H2 also recommended clarifications to UN-R 134/03 regarding ‘appropriate adaptor’ definition and changes to related paragraphs, with informal document due December 2026.

IWG CLIV Phase 2 addresses development of UN Regulations for buses and coaches and light vehicles. The 13th through 17th sessions, held virtually and in-person in Seoul from March to June 2026, focused on drafting a bus UN Regulation and refining text on scope, definitions, visual signals, and transitional provisions. Feedback from GRE and GRSG indicated further amendments needed, particularly regarding scope clarity and vehicle exemptions. Formal submission of the bus UN Regulation is anticipated at the 80th GRSP session, with feedback requested by 10 June 2026.

Proposal to establish requirements for vehicles of categories M₂ and M₃ class B and III designed or equipped primarily for the carriage of children:

• Requiring physical inspection systems to assist in the prevention of children being left inside the vehicle after journey completion,
• specifying that such systems shall be engaged when the vehicle master control switch is turned off,
• shall generate external visual and audible warnings within 3 minutes for vehicles not exceeding 22 passenger seats or within 5 minutes for vehicles exceeding 22 passenger seats if not disarmed via an inspection confirmation device located behind the rearmost passenger seat,
• that external warnings shall consist of type approved direction indicator lamps flashing at the same frequency for at least 15 seconds with intervals of no greater than 30 seconds repeating in cycles of no less than 10 minutes and audible warnings greater than 60dB(A) following the same timing,
• and establishing test procedures, conformity of production requirements, approval procedures, modification and extension provisions, and notification procedures to the United Nations secretariat.

Emergency Door Opening Task Force reports transformation to Informal Working Group based on GRSP-79-18. Amendments to UN R11 require doors providing direct occupant access equipped with intuitively accessible exterior and interior latch release controls and door handles. Power-assisted systems must remain functional for 60 minutes after power loss via secondary mechanical means, backup power, or fail-safe systems. New test procedures verify door operability following emergency power loss events from interior and exterior. Amendments to UN R21 require electric front side windows to function for at least 2 minutes during vehicle submergence, with test procedures specified in new annexes.

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.

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.

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.
