What are the Fatigue Management Requirements under the Chain of Responsibility?

What are the Fatigue Management Requirements under the Chain of Responsibility?

Chain of Responsibility

Under the Heavy Vehicle National Law (HVNL) parties in the CoR and under the fatigue management laws - ”a driver must not drive a fatigue-regulated heavy vehicle on a road while impaired by fatigue or in breach of work and rest hour requirements.”

A fatigue-regulated heavy vehicle is:

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


Driver Fatigue

Fatigue is a major work health and safety hazard for truck drivers. The Heavy Vehicle Driver Fatigue reforms were introduced in September 2008. These reforms were carried over into the HVNL. The HVNL defines “fatigue” as when you feel:

  • sleepy;
  • physically or mentally tired, weary or drowsy;
  • exhausted and/or lacking in energy; or
  • acting in a way consistent with the above.


Work and Rest Hours

Drivers must comply with certain maximum work and minimum rest limits. Parties in the supply chain must do all that is reasonably practicable to prevent drivers from exceeding these limits. Work time refers to the time taken for:

  • All driving; and
  • Any other task related to the operation of a fatigue-regulated heavy vehicle.


Options for Managing Hours

Due to the wide nature of businesses and industries, there is “no one size fits all” for managing driver work and rest hours. Therefore, the HVNL sets out three options for managing hours that allow for increased flexibility without compromising safety.


The first option is Standard Hours. Standard hours are for drivers and operators not operating under a National Heavy Vehicle Accreditation Scheme (NHVAS) or an exemption. It prescribes the maximum work and minimum rest that can be performed safely without additional safety countermeasures.


Next is Basic Fatigue Management (BFM). BFM is where drivers and operators must be accredited under the NHVAS. This allows for more flexible work hours including up to 14 hours in a 24-hour period.


The third option is Advanced Fatigue Management (AFM). Under AFM drivers and operators must be accredited under the NHVAS. Rather than prescribed work and rest hours, AFM offers flexibility to propose it's own hours based on a risk-based approach to managing fatigue. This is primarily suited to line haul-type operations.


Record Keeping

Under the record-keeping requirements, a driver of a fatigue-regulated heavy vehicle must record their hours in a National Driver Work Diary when they are driving outside a 100km radius from their base under Standard Hours; or when operating under BFM, AFM or an exemption regardless of the distance. A driver is not legally required to use a Work Diary if they always do local work, that is driving only within a 100km radius of their base) under Standard Hours.


Managing Fatigue in your Business

The key elements of Managing Fatigue in your Business include:

  • Conducting a risk assessment of operations that may cause a driver to drive while impaired by fatigue or in breach of work and rest hour requirements.
  • Documenting fatigue management policies and procedures that outline the control measures.
  • Consulting with other parties on how they manage fatigue – for example, request a copy of their fatigue management risk assessment, policies and procedures.
  • Conducting regular contract reviews of the effectiveness of controls implemented by others in the supply chain.
  • Ensuring contracts and agreements do not contain incentives (for early pick-up or delivery) or penalties (for late delivery) that may cause or encourage the driver to drive whilst fatigued or breach their work and rest hours.
  • Ensuring Commercial arrangements include prescriptive requirements to comply with legal obligations.

By Dean Woods • October 13, 2026
Welcome to Take 5, Zenergy's weekly five-minute scan of what's moving in Australian workplace health and safety, workers compensation and people & culture — five items, one featured senior role, every source named. This week: a hard regulatory deadline lands on the calendar, Safe Work Month hits its stride, and Safe Work Australia publishes the clearest picture in years of who is actually exposed to harm at work. 1. New workplace exposure limits commence 1 December — including Australia's first diesel particulate limit The transition period for Safe Work Australia's updated workplace exposure limits (WELs) for airborne contaminants ends on 1 December 2026. The list introduces Australia's first national exposure limit for diesel particulate matter — 0.01 mg/m³, measured as respirable elemental carbon — alongside revised limits for a range of other contaminants. Regulators are telling duty holders to use the remaining weeks to review exposure monitoring, confirm controls are effective, and prioritise elimination and engineering controls over reliance on RPE. If your operations involve diesel plant in enclosed or poorly ventilated environments — distribution centres, tunnels, underground mining, workshops — this is the compliance item to table at your next leadership meeting. Safe Work Australia has published guidance and a transition toolkit, and state regulators including SafeWork SA have flagged the change, as has NOPSEMA for offshore operators. Sources: Safe Work Australia — Changes to Workplace Exposure Limits (safeworkaustralia.gov.au); SafeWork SA — Get ready for new Workplace Exposure Limits (safework.sa.gov.au); NOPSEMA — Diesel engine emissions: new workplace exposure limit takes effect December 2026 (nopsema.gov.au). 2. Dates ahead: Safe Work Month's “for health” week and World Mental Health Day National Safe Work Month is underway, with Safe Work Australia's 2026 theme “Safe work is for life” running week-by-week focuses: “for health” (week two, this week), “for the future” (week three) and “for all” (week four). World Mental Health Day falls on Saturday 10 October, inside Mental Health Month — a natural prompt to put psychological health on the toolbox agenda, not just the poster wall. Regulators are active too: SafeWork NSW opened the month with a compliance operation targeting the meat processing sector. Sources: Safe Work Australia — National Safe Work Month (safeworkaustralia.gov.au/national-safe-work-month); SafeWork NSW — news, 1 October 2026 (safework.nsw.gov.au). 3. People & culture: FWO recovers $453 million for workers in 2025–26 The Fair Work Ombudsman's 2025–26 results, released 14 September, show $453 million recovered for underpaid workers across the year, with Ombudsman Anna Booth urging employers to find “compliance common ground”. For employers, the signal hasn't changed: payroll governance, award classification and record-keeping sit alongside WHS as enterprise-level compliance risks — and the regulator's recovery capability keeps growing. Worth a standing item on the people & culture risk register, especially for businesses with large award-covered or labour-hire workforces. Source: Fair Work Ombudsman media release, 14 September 2026 (fairwork.gov.au/newsroom). 4. Job market pulse: national vacancies ease, HSE demand holds The ABS's August 2026 Job Vacancies figures (released 1 October) show 325,000 vacancies nationally — down 0.9% over the quarter and 1.3% over the year, and 31.2% below the May 2022 peak. Private sector vacancies fell 2.0% for the quarter while public sector vacancies rose 7.8%. Health care and social assistance remains the deepest vacancy pool at 54,300. Against that gently easing backdrop, safety hiring is holding its ground from WHS advisors in Melbourne manufacturing to safety leadership in Queensland logistics — a spread we read as steady, sector-broad demand for proven operators rather than a hiring spike. Sources: ABS — Job Vacancies, Australia, August 2026 (abs.gov.au); 5. Industry story of the week: 68% of workers likely exposed to at least one hazard Safe Work Australia's newly published Worker Exposure Survey finds 68% of Australian workers are likely exposed to at least one physical or chemical hazard at work, with 28.9% experiencing high-level exposure. Solar UV is the most common hazard (an estimated 4.87 million workers), silica exposure covers an estimated 2.04 million workers and is heavily concentrated in construction and mining, and apprentices and trainees are disproportionately exposed across heat, silica, lead and asbestos. Construction, agriculture and mining are the industries most likely to see multiple hazard exposure. It's the week's most important read for HSE leaders — and the subject of this week's Zenergy deep-dive, where we unpack what the numbers mean for exposure monitoring, young-worker supervision and the 1 December exposure limit deadline.
