Road signs are a major part of road safety in Australia, and are designed to be quick to read and easy to understand.

The majority of road signs can be categorised into three main groups: regulatory, warning and information. Here in Australia, we also have specific animal road signs.

Refresh your knowledge of Australia’s road signs and understand the meaning to keep you safe on the road.

Regulatory signs

These types of road signs control traffic and must be adhered to while driving. They are almost always red and/or black on a white background.

Here is a list of regulatory signs:

Speed signs – these signs warn drivers of the maximum speed you can drive

School Zone – you must not go faster than 40km/h between the times stated

Stop – you must stop and give way to all traffic

Give way – you must slow down and prepare to stop

Parking signs – you must not park in the designated area

Roundabout – you must be prepared to give way when approaching a roundabout

No left turn – you must not turn left. This sign can also be displayed without words.

Keep left – you must keep left

No entry – you must not enter

Two way – the road is two lanes

One way – the road is one way to the left

Transit lane (T3) –transit lane limited to vehicles with three or more occupants between specified times and days.

Warning signs

These road signs will alert you to any possible dangers ahead. They are usually yellow with black symbols or letters and (mostly) diamond in shape. There are two types of warning signs: permanent and temporary.

Permanent warning signs

These road signs will make you aware of any upcoming road conditions. This can indicate the presence of people, animals, or a hidden change in the road. They are usually placed at the start of an area of caution.

DIP – unexpected or hidden dip in the road

Winding road – sometimes this road sign will have a recommended speed limit written underneath the symbol

Steep downhill slope ahead – take care when braking

T-intersection – prepare to slow down, stop, and give way

Temporary warning signs

These road signs alert drivers of any temporary road hazards. This may include roadworks, road accidents, fallen trees or floods. They are always placed at the start of an area where extra caution is needed.

Road works

Left lane closed

Temporary warning triangle – alerting an incident ahead (accident or road blockage)

Information signs

These road signs supply you with information that you’ll need for a road trip like distances, state highway numbers and road conditions. These signs are normally a rectangle shape and vary in size and colour.

Speed ahead – alerts you of change in speed ahead and encourages you to start slowing down

Guides and route markers – tells you where to exit highways and freeways. Route markers steer drivers onto major routes (popular road trips etc.)

Low clearance – indicates height available under a bridge or other obstacle

Dual carriageway – road becomes a dual carriageway

Vehicle-mounted signs

These special signs are reserved for large road trains that are supported by pilot vehicles. These heavy vehicles usually carry very large loads on public roads and rely on special signage to signal to driver’s that they should slow down until it’s safe enough to drive at a normal speed.

Australian animal road signs

These road signs will alert you to any animal that you may encounter on Australian roads. Australia has a large amount of animals that can cause an accident while on the road. Similar to warning signs, animal road signs are usually yellow with black letters and symbols.

Here is a list of animal road signs:








Stock crossing


Special road signs by state

Road signs and their rules can vary in different Australian states so it’s important to follow the rules according to the state you’re currently in.


In Victoria you can make a “hook turn” at an intersection when you see a “Right Turn from Left Only” sign. Drivers are also permitted from making a U-turn at traffic lights unless there’s a sign prohibiting it.

In Queensland you must be in the left lane while driving through an intersection at a “Through Traffic Keep Left” sign.

In Western Australia keep an eye out for any signs indicating “Roundabout Directional Lanes”. These signs identify when you can use multiple lanes at a roundabout and what direction you can turn in according to the lane you’re driving in.
