National Harmonisation Program 

The NHVR has established the National Harmonisation Program (NHP) to improve heavy vehicle regulation consistency. The key objectives of this program are to minimise the compliance burden on the heavy vehicle transport industry, reducing duplication and inconsistencies across state and territory borders. The initial work program includes the development of the following four priority national notices and associated networks:

  • Higher Mass Limits (HML) Declaration
  • Class 2 B-double Notice
  • Class 2 Road Train Notice
  • Class 1 Agricultural Vehicle and Combination Notice.

National HML Declaration

Our goal is to develop a National HML Declaration to authorise the operation of HML vehicles. The National HML Declaration aims to replace transitional arrangements for HML operations in several states and to enact the standard conditions for HML as per the Heavy Vehicle (Mass, Dimension and Loading) National Regulation.

The relevant notices for HML operation can be found here.

National Class 2 B-double Notice

This project consists of a comprehensive review and redesign of the existing National Class 2 Heavy Vehicle B-double Authorisation (Notice) 2014 aimed at improving the consistency of B-double access and vehicle conditions nationally. This project will also integrate existing state based B-double transitional notices into the new national notice.

The relevant notices for B-double operation can be found  here.

National Class 2 Road Train Notice

Our objective is to conduct a comprehensive review and redesign of the existing National Class 2 Heavy Vehicle Road Train Authorisation (Notice) 2015. We aim to create a nationally harmonised notice by producing standard definitions and categorisation of road train configurations and improve the overall consistency of access and vehicle conditions.

The relevant notices for road train operation can be found here.

National Class 1 Agricultural Vehicle and Combination Notice

Our aim is to develop a National Class 1 Agricultural Vehicle and Combination Notice to authorise the operation of agricultural vehicles and combinations. This national notice will replace transitional arrangements for agricultural operations in several states and will harmonise the dimension limits and access conditions.

The relevant notices for agricultural vehicle and combination operation can be found here.

Next steps

The NHVR will be consulting with key industry associations, local government, state and territory road transport authorities throughout the duration of these projects. In particular, engagement with road managers will be instrumental in developing networks supporting the four national notices.

The priority notices project timelines are as follows:
