W16-4 Children Sign (WU2) are used to warn drivers to slow down and take care, as there is a likely presence of considerable numbers of pedestrians (less than 16 years of age). The WU2 Warning Sign consists of a CHILDREN symbol displayed on a standard PW diamond sign plate. Old Mostam code was PW-31.
For standard pedestrian warning, a W16-1 Pedestrian Sign (WU1) can be used instead. All WU Warning - Non Motorised signs should be made with VFL Fluorescent Lime/ Yellow reflective.
