If you operate a heavy vehicle in NSW, understanding your fatigue obligations under the Heavy Vehicle National Law (HVNL) isn’t optional — it’s a legal requirement. Heavy vehicle fatigue is one of the leading causes of serious crashes on NSW roads, and the NHVR enforces fatigue rules strictly across all registered operators.
This guide explains what the NHVR fatigue rules mean for heavy vehicle operators in NSW, what compliance looks like in practice, and how proper fatigue management training protects your licence, your drivers, and your business.
What Is the Heavy Vehicle National Law (HVNL)?
The Heavy Vehicle National Law (HVNL) is the framework that governs heavy vehicle safety across all participating Australian states and territories, including NSW. Under the HVNL, heavy vehicles are defined as those with a gross vehicle mass (GVM) of more than 4.5 tonnes.
Fatigue rules under the HVNL apply to both drivers and operators. Operators have a primary duty to ensure their systems, schedules, and practices do not cause or contribute to driver fatigue. This is separate from — and in addition to — the driver’s own obligations.
The Three Fatigue Management Categories
NSW heavy vehicle operators must comply with one of three fatigue management options under the NHVR framework:
- Standard Hours — the default, no accreditation required. Prescribes maximum work and minimum rest hours.
- Basic Fatigue Management (BFM) — requires NHVR accreditation and BFM-trained drivers and supervisors. Allows more flexible work/rest patterns.
- Advanced Fatigue Management (AFM) — highest flexibility, requires scientific fatigue risk assessment and NHVR approval.
Most NSW operators start with Standard Hours. If your business runs long-haul routes or irregular schedules, BFM accreditation is worth investigating. Kells Safety Centre delivers BFM training in Wetherill Park and Wollongong.
Standard Hours: What Operators Need to Know
Under Standard Hours, the NHVL sets the following maximum limits for solo drivers of heavy vehicles:
| Period | Max Work Hours | Min Rest Required |
|---|---|---|
| In any 24-hour period | 12 hours work | 7 hours continuous rest |
| In any 7-day period | 72 hours work | 24 hours continuous rest |
| In any 14-day period | 144 hours work | 2 x 24-hour rest periods |
These are hard limits. Operators who schedule drivers beyond these hours — even indirectly through commercial pressure — can be held liable under Chain of Responsibility laws.
Operator Obligations Under Chain of Responsibility
Under Chain of Responsibility (CoR), heavy vehicle operators are legally accountable for ensuring their drivers are not fatigued. This means operators must:
- Not set schedules or timeframes that require drivers to exceed fatigue limits
- Not offer incentives (financial or otherwise) that encourage speeding or fatigue law breaches
- Maintain work diary records for all drivers operating under HVNL
- Conduct regular fatigue risk assessments where BFM/AFM applies
- Ensure supervisors and schedulers understand their fatigue obligations
The NHVR and NSW Police conduct roadside checks and operator audits. Fatigue-related CoR breaches can result in substantial fines and, in serious cases, criminal prosecution.
Work Diaries: What Operators Must Keep
Drivers of vehicles over 12 tonnes GVM must keep a work diary (unless exempt). As an operator, you are required to:
- Supply drivers with approved work diary books
- Retain completed diary records for a minimum of 3 years
- Make records available for NHVR inspection on request
- Cross-check driver records against your own scheduling records
Electronic work diaries (EWDs) are an approved alternative and are increasingly used by larger NSW fleet operators.
BFM Accreditation for Operators
If your operation would benefit from more flexible work/rest schedules, Basic Fatigue Management (BFM) accreditation through the NHVR is the next step. BFM requires:
- All drivers to hold a current BFM certificate
- At least one supervisor trained in BFM fatigue management
- NHVR accreditation for your business
- Fatigue risk management policies and procedures
Kells Safety Centre (RTO 91528) delivers the BFM course at Wetherill Park and Wollongong. Upon completion, drivers receive a statement of attainment that satisfies the NHVR’s BFM training requirement.
Frequently Asked Questions
Do I need NHVR accreditation as a heavy vehicle operator in NSW?
Not necessarily. Standard Hours applies to all heavy vehicle operators by default and doesn’t require NHVR accreditation. You only need NHVR accreditation if you want to operate under BFM or AFM, which allow more flexible work/rest schedules than Standard Hours.
What happens if my drivers exceed Standard Hours?
Exceeding Standard Hours is a breach of the HVNL. The driver faces infringement notices, and as the operator you can face Chain of Responsibility penalties — including substantial fines if your scheduling contributed to the breach. Serious or repeat breaches can result in court proceedings.
How long do I need to keep work diary records?
Under the HVNL, operators must retain work diary records for a minimum of 3 years. Records must be available for inspection by NHVR or authorised officers on request.
Can schedulers and dispatchers be held liable for fatigue breaches?
Yes. Under Chain of Responsibility, schedulers and dispatchers who set routes or timeframes that require fatigue law breaches can be held personally liable — not just the operator entity. This is why fatigue awareness training for scheduling staff is increasingly important.
Where can I get BFM training for my drivers in NSW?
Kells Safety Centre (RTO 91528) delivers BFM training at Wetherill Park (Western Sydney) and Wollongong. Courses are run regularly and include the statement of attainment required for NHVR BFM accreditation. View all available course dates.

Practical Compliance Steps for NSW Operators
For most heavy vehicle operators in NSW, fatigue compliance comes down to five practical areas:
- Scheduling review: Audit your current run times against Standard Hours limits. Any run that regularly requires drivers to exceed 12 hours of work in 24 hours is a compliance risk.
- Work diary supply: Ensure every driver over 12 tonnes GVM has a current work diary and understands how to complete it correctly. Incorrect or missing entries attract infringement notices at roadside checks.
- Supervisor training: Schedulers and operations managers should understand their CoR obligations. If a scheduler sets an unrealistic run, they can be held personally liable under HVNL.
- BFM consideration: If your operation regularly pushes against Standard Hour limits, BFM accreditation may provide the flexibility you need while remaining fully compliant with NHVR rules.
- Record retention: Maintain all work diary records for a minimum of 3 years. Make records accessible to NHVR inspectors on request.

Frequently Asked Questions
Does every heavy vehicle operator need NHVR accreditation?
No. Standard Hours applies by default — no accreditation required. You only need NHVR accreditation if you choose to operate under BFM or AFM, which allow more flexible work and rest patterns than Standard Hours.
What is the maximum work time under Standard Hours for solo drivers?
Under Standard Hours, solo heavy vehicle drivers can work a maximum of 12 hours in any 24-hour period, with a minimum of 7 hours continuous rest. In any 7-day period, the maximum is 72 hours work with at least 24 hours continuous rest required.
