- Enforceable. The number is a maximum for good conditions.

- 3 questions ask about this sign
What to do when you see it
- Keep to 110 km/h or less, and treat that as a maximum in good conditions rather than a target.
- Leave a bigger gap than feels necessary, since at this speed you cover more than 30 m every second.
- Rest before you are tired, because a 110 zone usually means a long rural drive rather than a short one.
Where you see it
On divided rural highways and long motorway sections, mostly outside the capital cities.
Across the states and territories
One hundred and ten is the highest limit posted in most of Australia. The Northern Territory is the exception, since it posts higher limits on some highway sections than any other jurisdiction, so a driver crossing the border in either direction should read the signs rather than carrying a habit across. Learner and provisional caps set by each jurisdiction can also apply below the posted number.
