KATRI reported on the 131st GRSG session. OICA raised concern that the scope of the draft regulation is not clear, noting that vehicles of categories M₂ or M₃ class B and III designed or equipped primarily for the carriage of children equals all of M₂ or M₃ vehicles since there is always a possibility of carrying children, and stated it is now checking TF STBC documents. CIVD stated that vehicles used for camping need to be exempted from scope, noting this is reasonable but questioning how. Denso asked whether warning method of visual and audible is different between buses and light vehicles, noting this is done, and stated it seems possible to add new regulation number in UN R48.
