Australian road signage are something we see every day but likely don’t know what constitutes a regulatory road sign versus an information sign.

Whether you’re on a back road in the middle of nowhere or a major metropolitan freeway, road signage is an integral part of keeping Australian roads safe.

While many governing laws and regulations can differ across states and territories, Australian road signage is administered by national guidelines, meaning there are very few differences between road signs in Australia.

While it can be easy to simply lump all road signs in Australia into one category, there are differences in how signs are managed and used depending on their purpose.

In this blog we will investigate the meanings of the main types of Australian road signs – the regulatory, guide and information, roadworks, warning, and hazard marker signs.

Regulatory Signs

Regulatory signs are the most common traffic signs you will see and are used to improve safety of road users. They indicate what you can and cannot do on the road and must be followed, otherwise you may incur a fine.

They are easy to recognise as they are usually combinations of white, black, red, yellow, and green. A good rule of thumb is that if you can receive a fine for not following the road sign’s instructions, it’s probably a regulatory sign!

The most common regulatory road signs you will come across include:

Give Way Signs

Give way signs are used at intersections, roundabouts, and cross walks to signify to simply ‘give way’ to foot traffic, drivers or even animals.

Stop Signs

Stop signs are generally used at intersections where it is harder for drivers to see oncoming traffic, which is why they are required to completely stop rather than give way. Drivers are required to come to a complete stop at or before the intersection, check for oncoming traffic or pedestrians and then continue when safe to do so.

Parking Signs

Parking signs explain whether a car can park in a certain position, how long for, if a ticket is required, whether it’s a clearway, a no stopping zone or a loading zone. Parking signs generally contain more detail and information that other road signs.

Other types of regulatory signs include ‘Pedestrian Crossing’, ‘Keep Left’, ‘No Entry’, ‘One Way’, ‘No U Turn’ and ‘Start Freeway’ signs, as are the ‘Slow’ and ‘Stop’ signs held by traffic controllers in road work areas.

Guide and Information Signs

Information signs are recognised by their green, white and black colours and provide helpful details that may assist road users. They will generally inform drivers of what’s coming up ahead. Guide and information signs are like parking signs as they may contain more text rather than symbols.

Examples of information road signs include:

Signs on Freeway

For example, to reduce speed, or if they are going the wrong way, i.e. entering the freeway from the wrong side. Signalling that the driver is approaching the end of freeway is also a common information sign used on freeways.

Route Markers

A route marker is a road sign that provides drivers information on the route they are travelling, approaching, or exiting from. Some common examples are numbers that identify how far away you are from connecting towns and cities.

Warning Signs

Warning signs are easily recognisable thanks to their diamond shape, fluorescent background and black symbols or text.

Some road warning signs may be red, such as ‘prepare to stop’ signs, or a bright green colour, such as a warning for pedestrians or children that may be in the area.

Warning signs use diagrams and symbols to alert you of potential hazards or dangers up ahead – for example, a black cross means a crossroad is ahead, or a black T means the road ahead is ending.

They will also signal curves or sharp turns ahead, giving you the opportunity to appropriately adjust your driving in a timely manner.

In Australia, road warning signs are also used to inform drivers of animals that may be in the area, such kangaroos, koalas or wombats, which are known to wander onto the road and can cause significant damage to cars if struck while driving.

Hazard Marker Signs

Hazard markers are signs used to signify when approaching an obstacle or driving past a hazard on the road. These road signs are easy to spot with their black and white colours and abstract patterns.

Some common examples of these types of road signs are left and right markers (used at curves or roundabouts), island markers, end of road markers (used at T-junctions) and narrow markers.

Roadwork Signs

Roadwork signage is temporary but must still be obeyed – this means that even if you know the road like the back of your hand, you should always be vigilant in looking out for signs.

When you see the ‘Roadwork Ahead’ sign, that is your cue to reduce your speed limit and look for further instructional road signs, as well as to look for any potential hazards.

You must follow signals from any traffic controller that is present, as well as give way to all workers on the site.
Roadworks often mean you will need to slow down, generally to 40 km h or 60 km h, depending on where the roadworks is taking place. The speed limit on these roadwork signs are enforceable – meaning if you fail to follow them, you can be fined.

Accompanying signage can also alert you to hazards such as loose stones, road or lane closures, upcoming temporary traffic lights and a lack of road markings, so it’s important to be aware of what signs are around you in roadworks!

Some common roadwork signs used to improve safety on roads include: Stop/Slow Traffic Bat and Class 1 Barrier Frame.

What font is used on Australian road signs?

The first set of rules for Australian road signs were made by the National Transport Commission in 1999. Part of these rules state that by standard road signs must use the AS1744 series fonts, based on the USA’s Highway Gothic typeface.

What colours are used on regulatory signs?

Regulatory signs are usually red and/or black with a white background. However, they can also be yellow or orange (general warning), green (permitted traffic or direction) and fluorescent green or yellow (pedestrian crossing or school zone).

What is the purpose of road signs?

The purpose of road signs is to:

  • Keep roads safe
  • Regulate and control the actions of road users
  • Guide and warn traffic of upcoming hazards or roadworks
  • Improve traffic flow
