The 98th EVE IWG session held virtually on July 15, 2026, adopted the agenda and discussed Phase 4 priorities for UN GTR 22, including Minimum Performance Requirements, State of Certified Range, conditioning cycles, and mutual recognition. Japan proposed sharing Part C verification results with all Contracting Parties. The IWG reviewed UN GTR 21 and UN GTR 25 status, covering MPRs, energy throughput, virtual distance verification, and battery replacement provisions. OICA will present their MPR position at EVE 100 and share Part C verification results at EVE 99. Japan will consult on hosting 2027 meetings targeting the week of February 15th.
Work-in-progress draft regulation to address the safety of children left in light vehicles, with changes to amend definitions of ‘Child’ or ‘Children’ to refer to individuals generally considered to be between 0 and 6 years old, replace “frequency” with “repetition rate” in warning requirements, and clarify system deactivation, warning delay, and internal visible warning procedures. The proposed regulation would cover vehicles of categories M1 and N1 with mass not exceeding 3,500 kg equipped with indirect sensing or direct sensing systems to detect children left unattended in vehicles.
The 21st IWG CLIV Session agenda for 8–11 September 2026 at UTAC Autodrome de Linas-Montlhry, France, focuses four meeting days on light vehicles. Drafting work with demonstrations occurs throughout the week. Day 1 includes introduction, official welcome, agenda adoption, progress summary, group photo, drafting regulatory text for LVs, research presentation on hot cars, and vehicle demonstration. Days 2–4 comprise drafting sessions for UNR for LVs, presentations including ISO WG on surrogate progression and vehicle demonstration, with closing remarks each day. The meeting ends 17:00 on Friday 11 September 2026.
The GRE Informal Working Group on Simplification of UN Lighting and Light-Signalling Regulations held its 73rd session in Brussels on 9-11 July 2025. SLR approved reports from the 70th and 71st sessions. The Homework Team R-150 will prepare an updated version of SLR-73-09 including a decision tree and justification for submission to GRE-93 or GRE-94. SLR experts will study the GTB draft proposal in SLR-73-04 (superseded by SLR-73-04/Rev.1) to simplify paragraphs 6.×.4. and 6.×.5. in Reg. 48. SLR-73-07/Rev.1 reflects the latest baseline document for Reg. 48 with agreed modifications. IMMA introduced baseline documents for Reg. 53 and Reg. 74 reflecting simplified definitions. CEMA will prepare a baseline document for Reg. 86. GTB will prepare an updated proposal for a CAD-based method to determine apparent surface for SLR-74. A special SLR session on apparent surface may be held on 10 September 2025 if equipment is available. Discussion continues on harmonisation of requirements, improving direction indicator visibility, and technological neutrality for light sources. The 74th SLR meeting is scheduled for 10-12 September 2025 in Brussels.
The 74th SLR meeting (Brussels, 10–12 September 2025) reviewed baseline documents for Regulations 48, 53, 74, and 86, with participants improving draft texts on simplified paragraph structures and definitions. Key topics included correction of errors in Regulation 150 (formal proposal for GRE-94 April 2026), apparent surface simplification with support for Alternative A and luminance method consideration, improved visibility of daytime running lights (OICA drafting proposal for December session), and harmonisation of requirements regarding prohibited if not allowed (seeking GRE feedback). Technological neutrality for light sources was deferred to informal discussions. The 75th meeting is scheduled for 10–12 December 2025 in Brussels.
The GRE Informal Working Group on Simplification of UN Lighting and Light-Signalling Regulations held its 75th session in Brussels, 10–12 December 2025. SLR reviewed and improved revised baseline documents for Regulations 48, 53, 74, and 86, reflected in SLR-75-10/Rev.1, SLR-75-16/Rev.1, SLR-75-17, and SLR-75-21 respectively. SLR endorsed corrections to Regulation 150-01 in SLR-75-02/Rev.1 and simplified paragraphs 6.×.4. and 6.×.5. in Regulation 48 per SLR-75-05/Rev.1 (superseded by SLR-75-05/Rev.2), with continued discussion at SLR-76. SLR tasked GTB to complete work on apparent surface definition and CAD method. SLR agreed the 76th meeting will be held 4–6 February 2026 in Brussels.
