UN IWG CLIV presented a draft UN R regulation proposal for buses at May UN GRSP session covering physical inspection system with no sensing required. Discussions on light vehicle regulation, paused since early 2026, can now resume. Light vehicles will have sensing related performance requirements. ISO CPD surrogates availability will be crucial to implement the regulation. UN IWG CLIV will hold a 4-day workshop from 08–11 September, likely at UTAC/France, focusing on light vehicles, welcoming ISO CPD expert participation and presentations on ISO CPD status and test tools.
