On roads where there’s a speed limit sign, you must not drive faster than that speed limit.
On roads where there’s no speed limit sign, you must not drive faster than the default speed limit:
- 50km/h in ‘built-up areas’ – areas with street lights and buildings next to the road less than 100m apart
- 100 km/h for all other roads.
You must not drive faster than the maximum speed allowed by your driver licence, even when a speed limit sign is higher.
|Driver licence||Maximum speed|
Heavy vehicles over 4.5 tonnes (GVM).
This includes LR, MR, HR, HC, MC licence classes.
Radar detectors and jammers
It’s illegal to have a radar detector or jammer in your vehicle.
A radar detector or jammer is anything that detects, interferes with or reduces the effectiveness of speed-measuring devices.
Penalties for speeding include:
- demerit points (including double demerit points)
- loss of licence
- taking away your vehicle or number plates.
The penalty increases the more you’re over the speed limit, and if you speed in school zones.
Learner and provisional P1 drivers will go over their demerit point limit for any speeding offence and their licence will be suspended.
See Speeding penalties.
Speed limit signs
Speed limit signs show you the maximum speed you can drive in good conditions. Slow down in poor conditions.
Regulatory speed signs
You must not drive faster than 50km/h. Regulatory speed limit signs have a white background with the speed limit in a red circle. You must not drive faster than the speed limit shown on the sign.
Variable speed limit signs
These are electronic signs placed in tunnels and on motorways and bridges where the speed limit changes based on the road conditions. You must not go faster than the speed limit shown on the sign.
Local traffic areas
A local traffic area is an area of local streets with a speed limit of 40km/h.
The lower speed limit means greater safety for all road users and more peace and quiet for people living in the area.
High pedestrian activity areas
High pedestrian activity areas have a speed limit of 30km/h or 40km/h.
This lower speed limit improves safety in areas with high levels of pedestrian activity, such as busy central business district zones and small suburban shopping strips.
A shared zone is where pedestrians, bicycles and other vehicles can share the road safely.
Shared zones have a speed limit of 10km/h. You must not drive faster than this speed limit. You must also give way to any pedestrian in a shared zone. This includes slowing down and stopping, if necessary, to avoid them.
A school zone is the area around a school between a ‘School zone’ sign and an ‘End school zone’ sign.
You must not drive faster than the speed limit in a school zone on school days during the times shown on the sign. School days are published by the NSW Department of Education.
Every school has at least one set of flashing lights, which operate during school zones times. ‘Dragon’s teeth’ are also painted on the road to make school zones more visible.
