We were established in 2013 as a statutory authority to administer one set of laws – the Heavy Vehicle National Law (HVNL) – which applies in all Australia's states and territories except the Northern Territory and Western Australia.

In the six states and territories where the HVNL applies, there are more than:

• 114,000 registered prime movers
• 1 million registered heavy vehicle units (including mobile cranes, trailers and agricultural vehicles)
• 269,000 registered operators
• 495 road managers.

Our vision is to have a safe, efficient and productive heavy vehicle industry serving the needs of Australia. We aim to achieve this by working collaboratively with industry, governments and partner agencies to:

• provide leadership and drive sustainable improvement to safety, productivity and efficiency outcomes across the heavy vehicle transport sector and the Australian economy
• minimise the compliance burden, while ensuring the objects of the HVNL are achieved and duty holders meet their obligations 
• reduce duplication of, and inconsistencies in, heavy vehicle regulation across state and territory borders.

Some state road transport authorities and other government agencies deliver various frontline services on our behalf. See National Services Transition for more information.
