About fatigue management

Driver fatigue or drowsy driving is a safety hazard for the road transport industry. The main causes of fatigue are not enough sleep, driving at night (when you should be asleep) and working or being awake for a long time.

National heavy vehicle driver fatigue laws apply to fatigue-regulated heavy vehicles. A fatigue-regulated heavy vehicle is:

  • a vehicle with a Gross Vehicle Mass (GVM) of over 12t
  • a combination when the total of the GVM is over 12t
  • buses with a GVM over 4.5t fitted to carry more than 12 adults (including the driver)
  • a truck, or a combination including a truck, with a GVM of over 12t with a machine or implement attached.

Some heavy vehicles are not classed as fatigue-regulated heavy vehicles. These include trams, motor vehicles modified to primarily operate as a machine or implement (plant such as agricultural machinery, bulldozers, tractors, etc.) and motorhomes specifically modified for residential purposes (not just built with a sleeper berth).

The laws cover all aspects of work and rest relating to heavy vehicles including:

  • work and rest hours
  • recording work and rest times
  • fatigue management exemptions
  • Chain of responsibility obligations.

At the heart of the laws for fatigue management is a primary duty - a driver must not drive a fatigue-regulated heavy vehicle on a road while impaired by fatigue.  Drivers may be impaired by fatigue even when complying with work and rest limits.

Fatigue management for farmers

The NHVR has produced a Fatigue management for farmers guidance sheet (PDF, 224KB) to address the most common questions from operators and industry bodies about the fatigue regulations that apply to farm operations under the Heavy Vehicle National Law.

Livestock Transport Fatigue Management Scheme

The NHVR commenced the Livestock Transport Fatigue Management Scheme on 1 July 2015, providing new opportunities for operators and drivers who become accredited with the NHVR.

Chain of responsibility

If you consign, pack, load or receive goods as part of your business, you could be held legally liable for breaches of road transport laws even though you do not drive a heavy vehicle. In addition, corporate entities, directors, partners and managers are accountable for the actions of people under their control. This is the ‘Chain of responsibility’ (COR).

Each person in the COR must take all reasonable steps to ensure that the driver of a fatigue-regulated heavy vehicle does not drive on a road while impaired by fatigue or breach road transport laws relating to fatigue. In addition to this, each person in the COR must take all reasonable steps to ensure a heavy vehicle driver can perform his or her duties without breaching road transport laws.
