The session agenda includes discussion of the current draft UN Regulation for buses and coaches including homework feedback, feedback on the proposal in GRE from the South Korea delegate, preparation for the 1–5 June 2026 GRSP meeting, and any other business.

From 1 July 2013 all new School Buses in Australia must be fitted with a Child Safety Alarm system hardwired from the vehicle ignition circuit and powered from the vehicle battery. The system must activate after no more than five minutes of operation or immediately once the passenger door has been opened or closed, cannot be overridden by the operator, and can only be deactivated after the disabling switch is actioned. The disabling switch must be located inside the vehicle behind the rearmost passenger seats requiring the driver to walk to the rear to deactivate it. An audible alarm must sound when the engine ignition switch is turned off and the disabling switch has not been actioned, and must be audible from up to 10 metres distance.
