Conditional registration

Conditional registration is available for vehicles in special circumstances eg. pastoral vehicles.

This allows you to:

  • drive on public roads under restrictions
  • compensate for the vehicle's non-compliance with safety on public roads.

All heavy vehicles under conditional registration must be:

  • identified with applicable conditions on their certificate of registration
  • carry a full statement of the conditions at all times when on a public road.

How to apply

To apply, fill in the VS47 Conditional registration form PDF (644.4 KB) and submit it when you register your heavy vehicle.


It's expected most heavy vehicles will have more than one condition listed below.


Vehicles who need operational limits or support including:

  • a pilot vehicle
  • an observer to meet field of view
  • a heavy un-braked trailer that may only be towed by a heavy vehicle.

This covers units used in special areas including:

  • remote areas (LO3)
  • construction zones
  • snowfields (LO1)
  • national parks (LO2).

Each jurisdiction would define the permitted or excluded areas and any unique locations.

Vehicles that should not have unrestricted ownership (fire tenders with heavy front axles) and should be reassessed before transfer to another owner.

Units that:

  • have over-dimensional length or width
  • need special visible treatment to alert other road users.

This may include mobile crane booms, lift forks and mulcher elevators that would otherwise be hazardous due to their poor visibility.

Machines where braking, steering and stability are of concern. One way of accepting these for road use is to apply speed limitations (engine governing). The onus for setting the safe operating speed limit would be on the vehicle manufacturer.

Speed limit must be specific to the nearest whole 10 eg. 50, 60 or 70 kilometres per hour.

This can apply to units where complying lighting is impractical for example:

  • special purpose machinery for road maintenance
  • over width cranes or mulching machines which could comply in every other aspect.
