Fatigue Management for Truck Drivers: HVNL Obligations and Chain of Responsibility
Australian truck drivers must comply with fatigue work and rest rules under the Heavy Vehicle National Law. This guide explains Standard Hours, BFM, AFM, Chain of Responsibility obligations, and how Truck Me's built-in logbook helps drivers and operators meet their compliance requirements.
The HVNL fatigue management framework
The Heavy Vehicle National Law (HVNL) requires drivers of regulated heavy vehicles over 4.5 tonnes GVM to manage their fatigue and record their work and rest hours. The law applies across Queensland, New South Wales, Victoria, South Australia, Tasmania, and the ACT. Western Australia and the Northern Territory have their own fatigue legislation.
There are three work and rest options under the HVNL. Standard Hours is the default and applies to all drivers who are not enrolled in an accredited fatigue management scheme. It sets fixed maximum work windows and minimum rest periods, designed to ensure drivers get adequate sleep before and during long trips. Basic Fatigue Management (BFM) and Advanced Fatigue Management (AFM) allow more flexible scheduling in exchange for NHVR accreditation and additional record-keeping obligations.
The purpose of the framework is not just administrative: driver fatigue is a primary cause of serious heavy vehicle crashes in Australia. The HVNL treats fatigue as a safety matter and structures penalties accordingly, with higher penalties for higher-risk breaches and enforcement extending to every party whose conduct contributes to a driver operating while fatigued.
Standard Hours, BFM, and AFM: what each requires
Standard Hours
Maximum 12 hours work in any 24-hour period. At least 7 consecutive hours of rest in every 24 hours. No more than 72 hours of work in any 7-day period. Drivers must carry a logbook recording work start and end times, rest locations, and rest durations. Standard Hours logbooks can be paper or digital. This option applies to the majority of Australian heavy vehicle drivers.
Basic Fatigue Management (BFM)
Allows more flexible work and rest windows than Standard Hours. Requires the operator to hold NHVR accreditation under the National Heavy Vehicle Accreditation Scheme (NHVAS). Drivers on BFM must use an approved Electronic Work Diary (EWD) in most jurisdictions. BFM is suited to long-haul operations where Standard Hours schedules are operationally difficult but the operator has the systems to support a fatigue management plan.
Advanced Fatigue Management (AFM)
Allows operators to design a custom fatigue management system based on scientific fatigue modelling. Requires NHVR accreditation and approval of the specific fatigue management plan. AFM is used by larger fleet operators running complex schedules that cannot be accommodated under Standard Hours or BFM. It carries the greatest flexibility and the greatest documentation burden. An approved EWD is required.
Chain of Responsibility: who is liable for fatigue?
Chain of Responsibility (CoR) is the legal mechanism that extends fatigue compliance obligations beyond the driver to every party in the supply chain whose conduct can cause or encourage a fatigue breach. Businesses that do not operate vehicles are not exempt.
Operators
Must not schedule or roster drivers in ways that make it impossible to comply with work and rest requirements. Tight schedules that can only be met by skipping rest breaks create operator liability regardless of who is driving.
Schedulers
Anyone who plans route times, delivery windows, or driver rosters has a CoR obligation. A scheduler who builds run times that require fatigue law breaches shares liability for those breaches.
Consignors
Businesses that book or direct freight movements can be liable if their booking terms, delivery deadlines, or payment structures pressure drivers to breach fatigue rules to meet the job.
Consignees
Receivers who demand delivery at a time or in a way that can only be achieved by a fatigued driver share liability for the breach. Booking windows that leave no room for legal rest are a CoR risk.
Drivers
Drivers have a direct obligation to comply with their work and rest option. An operator instruction to push through does not remove driver liability under the HVNL.
Loading managers
Delays at the loader that push a driver into breach of their rest window can attract loading manager liability. Detention time that forces rest law breaches is a recognised CoR risk.
Practical CoR implication
A consignor who sends a booking with a delivery deadline that cannot physically be met without the driver skipping a mandatory rest break has committed a CoR fatigue offence. The NHVR has prosecuted supply chain parties who were not present in the vehicle at the time of the breach. CoR compliance requires businesses to actively audit the downstream effects of their scheduling and booking practices.
How Truck Me supports Standard Hours compliance
Truck Me's built-in logbook records the information Standard Hours drivers need, integrated into the normal trip workflow so nothing extra has to be remembered.
Trip start and end time recording
Truck Me prompts you at the start and end of every trip to record work hours. Under Standard Hours, this covers the core logbook requirement with minimal effort.
Rest break reminders
A popup alert warns you when a rest break is due based on your recorded work time. Set your fatigue option in your driver profile and Truck Me calculates the window for you.
Trip log export for audits
Export your logbook to PDF or CSV directly from the app. PDF format is readable by roadside inspectors on screen. CSV format suits operators and fleet compliance teams.
Rest break logging with GPS
On the full tracking tier, tap once to start a rest break. Truck Me records start time, end time, and GPS location automatically, with no manual entry required.
Fatigue option aware
Set your work and rest option, Standard Hours, BFM, or AFM, in your driver profile. The logbook records the correct fields for your chosen scheme.
Integrated with routing
Logbook recording starts when you begin navigation and ends when you arrive. No separate app, no separate login. Fatigue management built into the trip workflow.
Frequently asked questions
What are Standard Hours for truck drivers?
Standard Hours is the default fatigue work and rest option under the Heavy Vehicle National Law. It sets fixed maximum work windows and minimum rest periods. The core rule is a maximum of 12 hours work in any 24-hour period, with at least 7 consecutive hours of rest. Over any 7-day period, drivers must not work more than 72 hours. Standard Hours applies to all regulated heavy vehicle drivers who are not enrolled in Basic Fatigue Management or Advanced Fatigue Management.
What is Chain of Responsibility for fatigue?
Chain of Responsibility (CoR) is the legal principle under the HVNL that extends fatigue compliance obligations beyond the driver to every party in the supply chain whose conduct can cause or encourage a fatigue breach. This includes operators, schedulers, consignors, and consignees. If a booking deadline requires a driver to skip a mandatory rest break, the party who set that deadline can be prosecuted alongside, or instead of, the driver.
What is the difference between BFM and Standard Hours?
Basic Fatigue Management (BFM) allows more flexible work and rest scheduling than Standard Hours in exchange for an accredited fatigue management plan under the National Heavy Vehicle Accreditation Scheme. BFM can permit longer individual work periods and different rest configurations, but requires additional record-keeping and NHVR accreditation. Advanced Fatigue Management (AFM) goes further, allowing operators to design a custom fatigue management system subject to NHVR approval. Both BFM and AFM require an Electronic Work Diary in most jurisdictions.
Does Truck Me replace a paper logbook?
Truck Me's logbook feature records the information required under the HVNL. Under Australian law, electronic logbooks are permitted provided they capture all required fields. Truck Me's full tracking tier records work start and end times, rest break locations and durations, and GPS trip data. However, the legal acceptability of a digital logbook can depend on your specific fatigue option and jurisdiction. Check the current NHVR guidance for your situation and confirm with your operator before switching from a paper logbook.
What are the penalties for fatigue offences under the NHVR?
Penalties are tiered by risk level. A substantial risk fatigue offence, where a driver is too fatigued to drive safely, can result in fines of several thousand dollars and court referral. Critical risk offences, involving severely impaired drivers, can result in the highest penalties under the HVNL plus potential prohibition from driving. CoR parties including operators and schedulers face their own penalty tier and can be prosecuted even if the driver is not. The NHVR can also suspend or cancel permits and accreditations following serious fatigue breaches.
What is an Electronic Work Diary?
An Electronic Work Diary (EWD) is a device or app approved by the NHVR for recording work and rest under BFM and AFM. An EWD must meet specific technical standards set by the NHVR. Not every digital logbook qualifies as an NHVR-approved EWD. Truck Me's logbook is designed for Standard Hours record-keeping. Drivers on BFM or AFM should confirm whether their EWD requirement is met by an NHVR-approved device, which may differ from a general logbook app.
