Speed limits


A vehicle's speed can affect the risk of a crash and the severity of injuries. 

The faster you drive the longer it takes your vehicle to stop. 

Exceeding the speed limit dramatically increases the risk of being involved in a crash. 

You must obey the road rules, take note of the speed limit and allow enough time to travel to your destination so you don't need to speed. 

Speed limit signs tell you the maximum speed you are allowed to drive in good conditions to keep you safe on the road. Where there is no posted speed limit sign, default speed limits apply.

The maximum speed limit of 130km/h applies on some sections of the Barkly, Stuart, Victoria and Arnhem Highways as indicated.

If you drive over the speed limit, you could face a traffic offence and penalties.

Drive at a speed to suit all of the following:

  • the traffic conditions
  • the type and conditions of the road
  • the weather conditions
  • the capabilities of your vehicle
  • your own driving ability.

Speed restrictions for your licence

Learner licence holders are restricted to a maximum speed of 80km/h unless accompanied by a licensed driving instructor. 

Provisional licence holders are restricted to a maximum speed of 100km/h.

Drivers of heavy vehicles such as buses of more than five tonnes gross vehicle mass (GVM) or other heavy vehicles of more than 12 tonnes GVM must not exceed 100km/h.

Vehicles travelling under permit conditions may also have a maximum speed limit imposed.
