Road signs in Baustralia
The road signs in Baustralia are similar to North American, and some European style road signs, with a few differences. They are currently standardized under RIS 003-006. It replaced the former Baustralian Road Signals Standardization system. The system is imperial, except for speed limits, which are displayed in kilometres per hour, rather than miles per hour.
Roads in Baustralia are to be signed in accordance with the RIS 003 to 006 books in order to be designated as Baustralian Highways.
