How the HVNL Fatigue Reforms Will Impact Heavy Vehicle Operators

29 May Blog

The Australian transport industry is preparing for one of the biggest fatigue-management changes in years, with the amended Heavy Vehicle National Law (HVNL) expected to commence in July 2026.

The reforms aim to improve road safety while also giving operators more flexibility in how fatigue risks are managed across different transport operations.

For fleet owners, operations managers, schedulers and drivers, these changes won’t just affect paperwork, they’ll influence rostering, compliance systems, driver welfare, Chain of Responsibility obligations and daily operations.

Here’s what the changes mean for industry.

A Bigger Focus on “Fitness to Drive”

One of the most significant changes under the amended HVNL is the introduction of the new Unfit to Drive duty.

Previously, fatigue was the primary focus. Under the reforms, the law will now recognise that a driver’s ability to operate safely can also be affected by:

• Illness
• Injury
• Mental health
• Alcohol
• Other drugs
• General physical fitness

Importantly, this duty applies to all heavy vehicle drivers operating vehicles over 4.5 tonnes, not just fatigue-regulated drivers.

This means operators will need to think more broadly about driver wellbeing and fitness, rather than simply managing work and rest hours.

Chain of Responsibility Obligations Will Expand

The reforms also place additional responsibility on parties within the Chain of Responsibility (CoR).

Under the amended HVNL, businesses must ensure their practices do not:

• Cause
• Encourage
• Pressure
• Incentivise

a driver to operate while fatigued or otherwise unfit to drive.

This could impact:

• Delivery scheduling
• Loading time expectations
• Driver rostering
• Shift allocation
• KPI structures
• Contractor management

For operators, this reinforces the importance of building realistic schedules and maintaining open communication with drivers about fatigue and health concerns.

Written Work Diary Changes Are Coming

The Written Work Diary (WWD) is also being updated to align with the new HVNL framework.

The NHVR says the updated diary will simplify some record-keeping requirements while incorporating the new fatigue terminology and compliance arrangements.

Key changes include:

• Drivers can record hours under the new Alternative Compliance Hours (ACH) arrangements
• Some fields become optional, including:
  • Day of the week
  • Standard Hours notation
  • Work and rest hour totals
• Terminology updates reflecting the amended HVNL

The updated diaries will be introduced gradually, meaning drivers can continue using existing diaries until completed.

This phased rollout should help reduce disruption during the transition period.

Electronic Work Diaries Will Continue Evolving

The NHVR is also working with Transport Certification Australia (TCA) on further improvements to Electronic Work Diaries (EWDs).

These updates are expected to begin rolling out from mid-2026 and are likely to support:

• Improved compliance monitoring
• Simpler fatigue tracking
• Better integration with business systems
• Reduced administrative burden

For operators already using EWDs, the reforms may create opportunities to streamline fatigue compliance processes even further.

Fatigue Accreditation Is Moving Toward Greater Flexibility

Another major shift is the move away from the traditional Basic Fatigue Management (BFM) and Advanced Fatigue Management (AFM) structure.

Under the new Heavy Vehicle Accreditation (HVA) scheme, operators will move toward a more flexible, performance-based system called:

Alternative Compliance Accreditation for Fatigue

This model is designed to better suit the wide variety of freight operations across Australia.

Instead of a rigid one-size-fits-all structure, operators will be able to access:

• Approved templated Tables of Hours
• Existing BFM-style arrangements
• Common AFM-equivalent arrangements
• Bespoke fatigue-management arrangements

Operators seeking customised arrangements will still need to demonstrate that any increased fatigue risks are being effectively managed.

For many fleets, this could provide greater operational flexibility while still maintaining strong safety outcomes.

What Operators Should Be Doing Now

Although the reforms are not expected to commence until July 2026, operators should begin preparing now.

Key areas to review include:

Fatigue policies and procedures

Ensure policies consider broader driver fitness factors, not just work and rest hours.

Scheduling and delivery expectations

Review whether current schedules could unintentionally pressure drivers.

Driver communication

Encourage early reporting of fatigue, illness or fitness concerns.

Training

Prepare operations staff, schedulers and managers for the expanded CoR obligations.

Technology systems

Assess whether current Electronic Work Diary or fatigue-management systems will support the new framework.

The Industry Is Moving Toward Smarter Fatigue Management

The amended HVNL reforms signal a broader shift in how fatigue and driver wellbeing are managed across the heavy vehicle industry.

Rather than focusing purely on hours and paperwork, the reforms aim to encourage a more practical, risk-based approach that balances:

• Safety
• Operational flexibility
• Driver wellbeing
• Real-world transport demands

For operators who proactively prepare, the changes may create opportunities to improve both compliance and operational efficiency moving forward.
