This Standard specifies the design and construction requirements for standard road signs provided for in AS 1742.1.
NOTE- Authorities responsible for the erection of signs are not encouraged to develop signs for their own use However, there will be instances where no suitable standard sign exists 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 their possible inclusion in the relevant Standards in due course It is most important that the proliferation of signs with differing designs of legend, symbol, etc, essentially for the same purpose, is minimized
