Heavy Vehicle National Law

The Heavy Vehicle National Law (HVNL) regulates the use of heavy vehicles that have a gross vehicle mass of more than 4.5 tonnes. It applies nationally, except for Western Australia and the Northern Territory. 

In all jurisdictions where the HVNL applies, legislation is in place that adopts the HVNL as a law of that jurisdiction.

The NTC manages maintenance and improvement of regulatory improvements to the HVNL. The National Heavy Vehicle Regulator (NHVR) administers and enforces it. 


Where does the HVNL apply?

It’s currently in force in:

  • Queensland
  • New South Wales
  • Australian Capital Territory
  • Victoria 
  • Tasmania
  • South Australia. 

Legislative provisions are in place that modify some parts of the law in some states and territories. To access these modifications please visit the relevant state and territory legislation websites where the HVNL applies. 


The HVNL is the result of a collaborative process led by the NTC. It involved industry and government to develop a nationally-consistent approach to heavy vehicle legislation and regulation based on model laws developed by the NTC.

The HVNL and its regulations commenced on 10 February 2014.

The HVNL as passed by the Queensland Parliament is adopted for implementation by the other participating states and territories in their parliaments.
