NHVR Fatigue Categories Explained: Standard Hours, BFM and AFM

The NHVR’s fatigue management framework is not a single rule — it’s a tiered system of three distinct categories, each with different work and rest hour allowances, different training requirements, and different levels of flexibility for drivers and operators.

If you drive a heavy vehicle in NSW or manage drivers, understanding the difference between Standard Hours, Basic Fatigue Management (BFM), and Advanced Fatigue Management (AFM) is essential — getting it wrong means a breach of national law.

The Three NHVR Fatigue Categories

Under the Heavy Vehicle National Law (HVNL), all heavy vehicle drivers must operate under one of three NHVR-recognised fatigue management options. Each is designed for a different level of operational flexibility and comes with different obligations.

Category 1 — Standard Hours

Standard Hours is the default category. No accreditation or special training is required — it applies to all heavy vehicle drivers unless they have elected to operate under BFM or AFM.

What Standard Hours allows:

• Maximum 12 hours work in any 24-hour period
• Minimum 7 hours stationary rest in any 24-hour period
• Maximum 72 hours work in any week
• Minimum 24 hours stationary rest in any week

Standard Hours is suitable for drivers on regular metropolitan routes and those not working extended or overnight shifts. It offers the least operational flexibility but requires no additional training beyond basic licensing.

Category 2 — Basic Fatigue Management (BFM)

BFM is the most widely used fatigue category in Australian long-haul and regional transport. It allows more working hours than Standard Hours — in exchange for completing accredited BFM training and operating under a documented fatigue management system.

What BFM allows:

• Maximum 14 hours work in any 24-hour period
• Minimum 7 hours stationary rest in any 24-hour period
• Maximum 84 hours work in any week
• Minimum 24 hours stationary rest in any week

BFM requirements:

• Driver must complete an NHVR-approved BFM course (TLIIF0005)
• Operator must be accredited under the NHVR’s BFM accreditation scheme
• Driver must maintain a compliant work diary
• Schedulers with CoR obligations should complete Schedulers Fatigue Management training (TLIIF0006)

BFM is the right choice for most operators who need extended operating windows beyond Standard Hours — without the complexity and cost of a full AFM system.

Category 3 — Advanced Fatigue Management (AFM)

Advanced Fatigue Management is the most flexible — and most demanding — fatigue management option. AFM allows operators to design custom work and rest schedules based on scientific fatigue modelling, subject to NHVR approval.

What AFM allows:

AFM does not have fixed hour limits like Standard Hours or BFM. Instead, operators develop a customised fatigue risk management plan — approved by the NHVR — that uses scientifically-validated scheduling to manage driver fatigue. This can allow longer working windows than BFM in specific circumstances.

AFM requirements:

• Operator must apply for and obtain AFM accreditation from the NHVR
• A fatigue risk management plan (FRMP) must be developed and approved
• All drivers and schedulers must complete relevant training
• Ongoing monitoring, auditing, and record-keeping obligations apply

AFM is typically suited to large transport operators with specialist logistics needs — mining operations, long-haul cattle transport, or routes where Standard Hours and BFM schedules are operationally unworkable. It is not commonly used by small or medium operators due to its compliance overhead.

Which Category Is Right for You?

The right fatigue category depends on your operational profile:

• Short-haul, metropolitan routes under 12 hours/day: Standard Hours is sufficient — no additional training required.
• Long-haul, regional, or overnight runs requiring up to 14 hours work: BFM is the practical choice — accredited training, clear hour limits, widely accepted.
• Complex, multi-leg operations that BFM can’t accommodate: AFM may be appropriate — but requires significant investment in accreditation and compliance infrastructure.

Most NSW transport operators work within Standard Hours or BFM. If you’re not sure which applies to your operation, contact the NHVR or speak with Kells Safety Centre for training advice.

Work Diary Requirements Across Categories

All heavy vehicle drivers in NSW must maintain a work diary — regardless of which fatigue category they operate under. The diary records work time, rest time, and location, and must be produced on request during a roadside inspection.

Under BFM and AFM, additional recording requirements apply, and the diary format must comply with NHVR specifications. Errors or omissions in a work diary are a compliance breach — even if actual hours were within legal limits.

Frequently Asked Questions

Can a driver switch between Standard Hours and BFM?

Yes, but the driver must be BFM-trained and the operator must hold BFM accreditation to use BFM hours. Switching between categories within the same work period has specific rules — refer to the NHVR’s fatigue management guidelines or your BFM training for the exact requirements.

Does every driver in a BFM operation need to complete BFM training?

Yes. Every driver operating under BFM hours must hold an NHVR-recognised BFM qualification — the TLIIF0005 unit of competency. Schedulers should also complete TLIIF0006 Schedulers Fatigue Management training.

What is the penalty for exceeding Standard Hours or BFM hours in NSW?

Penalties include infringement notices, fines, and potential prosecution depending on the severity of the breach. Serious or repeat breaches can result in licence suspension. Chain of Responsibility liability extends to employers and schedulers.

How long is BFM training and where can I do it in NSW?

The BFM course (TLIIF0005) is a 1-day course available at Kells Safety Centre. It is also available as an online course for self-paced completion. See the BFM course page for current dates and fees.

Is AFM available to any operator or only large companies?

AFM accreditation is open to any operator but involves significant administrative, training, and compliance obligations. In practice, it is most suitable for large operators with specialist scheduling needs.

What Happens If a Driver Exceeds Their Category Hours?

Exceeding the work and rest hour limits for your fatigue management category is a breach of the Heavy Vehicle National Law (HVNL). Consequences include:

• Infringement notices issued at roadside inspections — fines apply to both the driver and the operator
• Chain of Responsibility liability — if a scheduler or operator contributed to the breach, they can be held personally accountable
• Vehicle detention — NHVR officers can detain a vehicle if a driver is found to be fatigued
• Loss of BFM/AFM accreditation — repeated breaches can result in accreditation being suspended or revoked by the NHVR

For complete regulatory detail on fatigue enforcement, refer to the NHVR fatigue management compliance guidance. If your operation is approaching the Standard Hours limits regularly, it is worth considering whether BFM accreditation would provide the flexibility you need.
