Road access for agricultural vehicles

You do not require a Class 1 agricultural vehicle permit, as long as moving the vehicle complies with all 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, you must apply for an access permit from the National Heavy Vehicle Regulator.

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 (PDF, 233.56 KB).
