| Children left in vehicles: Draft UN Regulation for approval of light vehicles |
| Reference Number: CLIV-20-02 |
|
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. |

| Simplification of Lighting Regulations: Report of the 73rd (July 2025) session |
| Reference Number: SLR-73-13 |
|
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 SLR experts will study the GTB draft proposal in SLR-73-04 (superseded by SLR-73-04/Rev.1) to simplify paragraphs 6.×.4.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. |
