Proposal to establish uniform provisions concerning the approval of M₂ and M₃ special purpose vehicles designed specifically for the carriage of children to assist in the prevention of children being left inside. The regulation applies to vehicles of categories M₂ and M₃, class B and III. Vehicles shall be equipped with a physical inspection system that engages when the vehicle master control switch is turned off and generates an external visual and audible warning if not disarmed within 3 minutes for buses or coaches not exceeding 22 passenger seats, or within 5 minutes for those exceeding 22 passenger seats. The physical inspection system shall not influence the bus or coach’s performance or safe operation, and failure of the system shall not affect safe operation of the vehicle.

Excerpts from session reports
GRSP | Session 79 | 1-5 Jun

11. The expert from Australia presented the status report of the IWG on Children Left in Vehicles (IWG-CLIV) (informal document GRSP-79-26), including meetings held by the IWG, proposals discussed at other GRs and future work. He also presented informal document GRSP-79-27 with a first draft of a new UN Regulation on CLIV for buses (M2 and M3 vehicles). GRSP discussed several topics including the incorporation of data submitted by the United States of America into the work of the IWG on a new UN GTR, prevention of false alarms, differences by country in procedures of embarking and disembarking school buses, intersection with ADS and the potential for deactivation of the CLIV features when buses were not used to transport children. The expert from Australia requested GRSP experts to send him any additional feedback before 10 June 2026 so that the group could incorporate it and submit a working document to the December 2026 session of GRSP.
