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. It is important to be aware of the signs of fatigue.

Electronic work diaries

The NHVR has released the draft EWD Policy Framework and Standards for public consultation. We expect to commence assessment and approvals of EWDs as a voluntary alternative to the written work diary in early 2018. Find out more...

Training in fatigue risk management

From 1 July 2018, new fatigue units of competency will come into effect. Any RTO intending to provide these new units for NHVAS purposes must first be approved by the NHVR. Find out more...

Fatigue-regulated heavy vehicles

National heavy vehicle driver fatigue laws apply to fatigue-regulated heavy vehicles, which are:

  • 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.

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

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.

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).

Signs of fatigue

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. It is important to spot the signs of fatigue and take a break.

Your body

  • A lack of alertness
  • Inability to concentrate
  • Making more mistakes than usual
  • Drowsiness, falling asleep or micro-sleeps
  • Difficulty keeping your eyes open
  • Not feeling refreshed after a sleep
  • Excessive head nodding or yawning
  • Blurred vision
  • Mood changes
  • Changes to personal health or fitness

Your vehicle

  • Near miss or incident
  • Not keeping in a single lane
  • Not maintaining a constant speed
  • Overshooting a sign or line
  • Poor gear changes

Work diary

Most drivers of a fatigue-regulated heavy vehicle are required by law to create a record of time spent working (including driving time) and resting on a daily basis. The HVNL names the circumstances where the National Driver Work Diary must be used as the method to create this record.

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.

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.

See the Chain of Responsiblity for more information.
