Frequently Asked Questions
- What’s the difference between a regulatory sign and a warning sign?
- Regulatory signs, such as Stop, Give Way, speed limit, No Entry and No Parking, set legal requirements you must obey. Warning signs, which are usually yellow diamonds like the roundabout, traffic-signals-ahead and slippery-road signs, alert you to a hazard or change in the road ahead so you have time to react. This guide explains both, sign by sign.
- What does a yellow diamond road sign mean?
- A yellow diamond sign is a warning sign: it tells you something is coming up on the road ahead, usually before you can see it yourself, so you can slow down and get ready. Examples on this page include the traffic-signals-ahead sign, the roundabout sign and the slippery-road sign. Unlike a regulatory sign, a warning sign does not by itself set a legal speed or command.
- Do road signs mean the same thing in every Australian state?
- The common regulatory and warning signs work the same way across the country, which is why this guide explains them for Australia as a whole. Even so, the underlying rules and pass requirements are set by each state and territory road authority and can change, so confirm the current details with the official source for your state, such as Transport for NSW, VicRoads or Queensland Transport.
