Mandatory speed limit signs:
- are white signs with a red circle around the speed number
- show the maximum legal speed for that section of road
- aren’t target speeds — you can drive slower if needed
- must be obeyed by law. If you go over the limit, you can be fined.
This includes:
- regular road speed signs
- temporary signs for roadworks, lane closures, or special events.
Advisory speed signs:
- are yellow signs with black writing
- suggest a safe speed for certain conditions, like sharp bends or steep descents
- are not enforceable by law but following them helps keep you safe.
Enforcement
Tasmania Police enforce mandatory speed limits. If you don’t follow them, you may receive a fine or other penalties.
