About limits
Speed limits
Excessive speed is one of the biggest killers on our roads. On average, 170 people die every year in New Zealand in speed-related crashes.
Remember, the faster you go, the more likely you are to be killed or seriously injured if you crash.
Safe speed guidelines
You can ride at any speed under or equal to the limit, provided:
- your speed is safe for the traffic conditions (for example, slow down if you are on a busy road, or if there are pedestrians or cyclists around)
- your speed is safe for the road conditions (for example, slow down if the road is winding, bumpy, narrow, wet or icy)
- your speed is safe for the weather conditions (for example, slow down if it is raining, windy or foggy)
- you can stop suddenly behind a vehicle that you’re following – if a vehicle ahead of you stops suddenly and you run into the back of it, you will be legally responsible
- you can stop in half the length of clear road you can see in front of you on a road with no centre line or lanes (for example, a narrow country road where vehicles may meet head-on)
- you can stop in the length of clear lane you can see in front of you on a road with a centre line or lanes.
Slow drivers
If you are travelling slower than the speed limit and there are vehicles following you, you must:
- keep as close to the left side of the road as possible
- pull over as soon as it is safe to let following vehicles pass.
Don’t speed up on straight stretches of road to prevent following vehicles from passing you.

Compulsory speed signs
A speed limit is the maximum legal speed that you can travel on the road under good conditions.
Signs showing the speed limit are displayed beside the road. These signs usually have a red border, which means that the sign is compulsory.
You may ride slower than the speed limit shown, but you must be considerate towards any vehicles behind you.
You must ride slower than the limit if:
- conditions make the speed limit shown unsafe.
Some examples of speed signs are shown below.
The maximum speed you can travel is 50km/h
The maximum speed you can travel is 70km/h
A temporary speed limit of 30km/h applies.
Temporary speed-limit signs are usually put up
when there is work being done on or near the road
Important
Speed limit changes take effect at the sign post.
Before reaching the speed-limit sign make sure you:
- reduce your speed, if the sign indicates a lower speed
- do not increase your speed until you pass the sign, if the sign indicates a higher speed.
Open road speed limits
The signs below mean that the maximum speed that you can travel at is 100km/h.
Maximum speed 100km/h
When following other vehicles, remember that some vehicles have lower speed limits and you may have to adjust your speed.
Some vehicles have a lower maximum speed limit, such as light vehicles towing trailers.
Important
If a driver exceeds a permanent posted speed limit by more than 40km/h, there is an automatic 28-day licence suspension.
If a driver exceeds a temporary speed limit by more than 50km/h, there is an automatic 28-day licence suspension.
Other signs that mean you must adjust your speed

Note: you may also see ‘Kura’, the Māori word for school, on a bus.
Curve warning signs
The signs below warn you that you are coming up to a tight curve or bend in the road. The number recommends a safe and comfortable speed to ride at around the curve – in this example the recommended speed is 35km/h. The arrows show which direction the curve goes.
