Variable speed limit signs are electronic signs that can change the speed limit based on road conditions.
They help keep everyone safe by adjusting the speed when needed, for example, if there is:
- a crash
- something blocking the road
- heavy traffic
- bad weather.
In Tasmania, variable speed limit signs are used on the Tasman Highway, from Liverpool Street in Hobart to the Cambridge Interchange, including the Tasman Bridge.
Tasmania also uses electronic school speed signs. These signs show lower speed limits during school times to keep children safe.
Each school sets its own times, so the speed zone hours may be different at each location.
