Agricultural vehicles and equipment

Under the Heavy Vehicle National Law an agricultural vehicle is defined as an agricultural machine or agricultural implement.

An agricultural vehicle is considered a Class 1 restricted access heavy vehicle if it, together with its load, does not comply with a prescribed mass or prescribed dimension requirement.

Examples of an agricultural vehicle include harvesters, tractors, augers and conveyors.


A Class 1 agricultural vehicle will not require a permit to operate provided the movement of the vehicle complies with all of the requirements and travel conditions outlined in a Notice or Ministerial Order.

If a Class 1 agricultural vehicle does not comply with the mass or dimension limits set out in a Notice or Ministerial Order, an operator must obtain an access permit.

There are multiple access arrangements for different classes of vehicle; generally the bigger and/or heavier the vehicle, the greater the safety risk and the more restricted the access. This is outlined in the Agricultural vehicles – Access in NSW fact sheet.

Since 25 February 2014 the following permit application process is in operation in NSW:
