You can get an exemption by applying for an oversize or overmass permit.
Permits will generally have conditions of operation on the vehicle – eg: route restrictions.
In the NT you need a permit for all of the following:
- a special purpose vehicle that, by construction, exceeds the legal mass and/or dimension limits – eg: cranes, drill rigs, plant-type vehicles
- low loaders and load platforms that are specially designed for the carriage of a large indivisible item or are carrying a large indivisible item
- vehicles and combinations that transport indivisible loads
- agricultural machines, agricultural implements or agricultural combinations.
You can also apply or renew to be an oversize load pilot or escort operator.
