Register an imported heavy vehicle

To register an imported heavy vehicle in the Northern Territory (NT) you need:

  • vehicle import approval issued by the Australian Government
  • steering conversion modifications (if required)
  • engineering certification if required
  • an NT roadworthy inspection.

Read the below on what else you may need for a specific heavy vehicle.


Vehicles over 4.5 tonnes GVM must be right-hand drive except for special purpose vehicles and Armed Forces vehicles.

If the vehicle is built on a conventional truck chassis, it will be classed as a truck. If the vehicle has more than nine seating positions, including the driver's seat, it is classed as a bus.

Vehicles imported under this category must have an Australian Identification Plate fitted via the 'Letter of Compliance Scheme', 'RAW Scheme' or 'Low Volume Approval Scheme'.

Trucks with a GVM up to 12 tonnes and buses with up to 12 seating positions must comply with the ADRs applicable to the vehicle’s date of original manufacture.

Trucks over 12 tonnes GVM and buses with more than 12 seating positions must comply with the ADRs applicable to the vehicle’s date of importation.

Special purpose vehicles are designed and built for purposes other than the transport of goods or people – eg purpose-built cranes.

Special purpose vehicles over 4.5 tonnes GVM may be registered in the NT in right-hand or left-hand drive configuration.

While the NT may accept these vehicles in a left-hand drive configuration, they may not be accepted for registration or operation in another state or territory.

For special purpose vehicles in the left-hand drive configuration, left-hand drive signage requirements will apply.

This sign is to be displayed on the rear of the vehicle with words of a font size of at least 75mm high and in colour contrast with the background of the words.

This agreement allows temporary importation of vehicles owned by overseas military personnel for personal use during their tour of duty.

Vehicles entering the NT under this agreement are not exempt from NT registration requirements.

NT registration requirements include, but are not limited to, the following:

  • the vehicle must comply with the roadworthy requirements of the home (overseas) jurisdiction in which the vehicle was most recently registered  - verification evidence may be requested
  • the vehicle must comply with the roadworthy condition as outlined in the NT inspection manual for heavy vehicles PDF (3.7 MB).

These vehicles are not required to be converted to right-hand drive.
