This Standard specifies graphics, layout and size requirements together with an abridged materials and manufacturing specification for the manufacture of the standard road signs provided for in AS 1742.

NOTE: Authorities responsible for the provision of signs are not encouraged to develop signs for their own use. However, there will be instances where there is no suitable standard sign. In such cases, the relevant State road authority should be contacted to determine whether such a sign is already in use. If a new sign is to be developed, it should comply with the design requirements specified in this Standard for the particular sign classification. If it is considered that the sign could also be required by other authorities, Standards Australia should be advised so that, during the course of its regular review of road signs, it can take all new developments into account with a view to possible inclusion in the relevant Standards. It is most important that the proliferation of signs with differing designs of legend, symbol or background, essentially for the same purpose, is minimized.
