The Informal Working Group on Advanced Emergency Braking System held its 2nd meeting on 18 June 2026. Australia had submitted documents GRVA/2026/21 and GRVA-25-36 proposing amendments to UN R152. For para. 2.14, the group agreed to insert a footnote stating “this value is understood to be a minimum value,” with a working document to be prepared for next GRVA. For para. 5.2.1.1, Australia withdrew its proposal to remove the 0.8s TTC warning condition after safety concerns were raised. CLEPA-OICA, UK and Australia will prepare a clarification proposal for next GRVA.
