Road repair crews often work on roads to keep them in good condition. This means you'll sometimes come across heavy vehicles, machinery and workers on the road, which you must be careful around. The road surface itself can also be dangerous when under repair, as it may be uneven or have new seal, loose gravel or mud.

When you see a roadworks sign, always slow down and be ready to stop.

Obey the signs

If there are roadworks on the road ahead, it'll always be clearly signposted. Slow down and read the signs. They'll prepare you for the particular hazards you're about to face.

Here are 2 of the signs commonly used to indicate roadworks.

Roadworks ahead

Flooding ahead

Because it can be dangerous to ride through roadworks or on new seal, temporary speed limit signs are often posted. You must ride at or below the speed shown on the temporary speed limit sign.


Crashes can happen when road users ignore roadworks warning signs and temporary speed limits. Take these warnings seriously. You don’t know what’s ahead, so slow down and take care.

Obey any directions given

Road repair crews may sometimes need to stop traffic. They may use temporary traffic signals or hand-held stop/go signs to do this. Follow all directions given to you, otherwise, you could be involved in a serious crash.

Stop before reaching the sign

You may move forward carefully

Detour signs

When a road is closed or being maintained, you may see detour signs showing you an alternative way around the road block.

You should follow the direction signs and expect to see them when approaching and leaving intersections. Take note of the shape and colour of the symbol on detour signage as one detour may pass through another.

Lane change signs

When roads or lanes are being maintained a truck with message board on it, called an attenuator, is often used. It directs traffic to an open lane in advance of roadworks. Slow down and follow the arrow.
