1998: Variable Speed Limit Signs is introduced

This year is 25 years since Sydneysiders were introduced to variable speed signage signs. 

There were speed advisory signs on the F6 Motorway (now known as Princes Motorway) when it opened in 1975, but they were primarily used to alert drivers of hazardous road conditions and recommend that they slow down.

The variable speed limit signs, which are now standard on Sydney motorways, were introduced first on the M4 Motorway in 1998. Below is a newspaper advertisement that was used to educate drivers on the new signs.
