CLEPA supports the general approach in the current draft UN R for children left in vehicles regulation. Systems shall detect presence of children through a technology neutral approach based on performance requirements. Door-logic based systems have known weaknesses and are insufficient as standalone solutions. Systems shall appropriately address situations where children are unknowingly or knowingly left in vehicles, with suitable test cases covering real-life relevant situations and child restraint system installations. CLEPA proposes replacing references to in-direct plus or direct sensing systems with sensing system throughout the regulation.

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.
