Register your heavy vehicle in the NT
Conditional registration is available for vehicles in special circumstances - eg: pastoral vehicles.
Conditional registration allows you to:
- drive on public roads under restrictions
- or compensate for the vehicle's non-compliance with safety on public roads.
The National Heavy Registration Scheme requires conditionally registered heavy vehicles to be identified as such on their certificate of registration by listing the applicable codes.
All conditionally registered heavy vehicles are required to carry a full statement of the conditions at all times when on a public road.
It is expected that most heavy vehicles will have a number of conditions.
The conditions are listed below.
How to apply
To apply for conditional registration you must fill in the conditional registration form and submit it to your nearest MVR office.
GO - general operation
Some vehicles require operational limits or support – eg: a pilot vehicle, or an observer to satisfy field of view, or a heavy un-braked trailer that may only be towed satisfactorily by a heavy vehicle.
LO - location of use limitation
This covers units that need to be used in special areas including remote areas (LO3), construction zones, snowfields (LO1) and national parks (LO2). Each jurisdiction would define the permitted or excluded areas and any unique location related requirements.
OL - ownership limitations
Some special vehicles, by their nature (fire tenders with heavy front axles) should not be available for unrestricted ownership and should be reassessed before possible transfer to another owner.
SL - signs and light
Units which are over-dimensional, particularly for length and/or width, need special visible treatment to alert other road users. Special delineation is typically required for mobile crane booms, lift forks and mulcher elevators that would otherwise be hazardous due to their poor visibility.
SP - speed limitation
For some machines, ranging from large construction equipment to three wheeled motorcycles, 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 maximum safe operating speed would be on the vehicle manufacturer. Speed limitation requirements are to be specified down to the nearest whole ten – eg: 50, 60 or 70km/h.
TR - time of day restrictions
This can apply to units where complying lighting is impractical, for example special purpose machinery for road maintenance, or over width cranes or mulching machines which could comply in every other aspect.
