Road signs in Australia

In 1999, the National Transport Commission (NTC), created the first set of Rules of the Road for Australia.

[2] In 1964, Australia adopted a variation of the American Manual on Uniform Traffic Control Devices (MUTCD) road sign design, which is a modified version of the 1954 revised version of the 1948 American edition of the MUTCD.

[3][4] The Australian adopted version had differences from the American version that it used red "give way" signs instead of yellow "yield" signs, "no entry" instead of "do not enter", round pedestrian crossing road signs (a carryover from the early days), the adoption of some road signage designs from the United Kingdom, and the use of imperial system of units (miles and yards) as in the UK as opposed to the customary system of units (miles and feet) in the US.

The year of 1974 saw important changes in Australia's road sign design practices.

A major change expressed Australia's preference for a transition to adoption of symbols on signs in lieu of words, inspired by the Vienna Convention on Road Signs and Signals, and transition to adoption of kilometres and metres in lieu of miles and yards.

Road users must obey all instructions on prohibitory signs or risk getting a fine and points deducted from their licence.
