AS 1742.1-1991

Specifies the basic colour and shape codings for the various classifications of traffic signs. The signs are illustrated in their respective colours in separate sections for regulatory, warning, guide and temporary signs and for hazard markers. The overall dimensions for the various sizes for each sign are given together with the numbers of other Standards in the AS 1742 series to which reference is required for the application of each sign in relation to a particular traffic situation.

This Standard covers the signs used for controlling vehicular and pedestrian traffic on the road. It defines the sign classifications, specifies the numbering system used and sets out the basic design of signs in terms of colour and shape codings. It provides an illustrated index of all signs and sign types which have a standard sign number, and includes sign sizes and reference to other Standards in this series which cover usage of each sign.NOTES:1 Traffic signals and pavement markings for general purposes are described in AS 1742.2. Where special pavement markings are specified, e.g. for bus lanes, these are given in the Standard which relates to that particular traffic situation.2 Detailed specifications for the design and manufacture of signs are given in AS 1743.
