NHVR work diary checks and fatigue enforcement: what transport operators must prove under the HVNL

What are NHVR fatigue enforcement work diary checks?

NHVR fatigue enforcement work diary checks are roadside and audit-based inspections in which authorised officers examine a driver's National Driver Work Diary (also known as a log book) to verify that work and rest hours comply with the Heavy Vehicle National Law (HVNL). The work diary is the primary evidentiary document that a driver has operated within permitted fatigue limits—standard hours, Basic Fatigue Management (BFM), or Advanced Fatigue Management (AFM). Operators must be able to produce supporting records that corroborate diary entries, including rosters, schedules, dispatch records, and telematics data, because enforcement extends beyond the driver to every party in the Chain of Responsibility.

The NHVR and state road enforcement agencies conduct these checks at roadside inspection sites, during targeted operations, and as part of broader compliance audits. If a work diary contains false entries, missing information, or evidence of breach, the operator and other CoR parties may face investigation, infringement notices, or prosecution.

Key takeaways

• The HVNL requires drivers of fatigue-regulated heavy vehicles operating 100 km or more from their base to carry and complete a work diary recording all work and rest times, with operators legally obligated to ensure driver compliance.
• Work diary checks are not just a driver obligation—employers, prime contractors, operators, and schedulers all share responsibility under HVNL section 264 to ensure drivers comply with work and rest requirements.
• Record keepers (typically the operator) must retain work diary records and related documentation for the period specified in the national regulations, and must be able to produce them during an NHVR audit or investigation.
• False or misleading work diary entries constitute offences under the HVNL, and extended liability provisions mean parties beyond the driver can be charged.
• CoRGuard supports fatigue compliance by centralising driver diary check records, corrective actions, and audit-ready evidence in a single system, so operators can demonstrate active compliance management.

What the HVNL Chapter 6 requires for fatigue management

The HVNL dedicates Chapter 6 entirely to vehicle operations and driver fatigue. This chapter establishes the legal framework for managing fatigue across all parties in the transport supply chain. The main purpose of Chapter 6 is to manage the safety risks associated with driver fatigue by imposing duties on drivers, employers, prime contractors, operators, schedulers, and consignors.

The principle of shared responsibility for fatigue

Under HVNL section 26A, the principle of shared responsibility applies to fatigue management. This means that every party whose actions influence a driver's fatigue—consignors, consignees, packers, loaders, operators, schedulers, and drivers—has a role in ensuring compliance. No single party can deflect responsibility by claiming fatigue management is solely the driver's problem.

Primary duty under the HVNL

HVNL section 26C establishes the primary duty: each party in the Chain of Responsibility must ensure, so far as is reasonably practicable, the safety of heavy vehicle transport activities. For fatigue, this means operators must take reasonable steps to ensure that scheduling, dispatch, and route planning do not cause or encourage drivers to exceed work hour limits or skip minimum rest periods.

Executive officer duty

HVNL section 26D imposes a separate duty on executives of legal entities (directors and senior managers). Executives must exercise due diligence to ensure the entity complplies with its primary duty. For fatigue management, this means executives must actively verify that the business has systems to monitor work diary compliance, manage rosters within legal limits, and address breaches promptly.

When must a driver carry a work diary?

Under HVNL section 293, a driver of a fatigue-regulated heavy vehicle must carry a work diary if they are operating under standard hours and travelling 100 km or more from their base. The NHVR's record-keeping requirements also extend this to drivers who have completed work of 100 km or more from their base within the preceding 28 days, meaning the obligation is ongoing rather than triggered only on the day of a long-distance trip.

Drivers operating under BFM or AFM accreditation must also maintain work diaries as evidence of compliance with their accredited fatigue management plan. The work diary must be carried at all times while driving a fatigue-regulated heavy vehicle and must be produced to an authorised officer on request.

What information must be recorded in a work diary?

HVNL sections 294 through 299 set out the information requirements for work diary entries. The national regulations prescribe the specific fields that must be completed, and the HVNL reinforces that information must be recorded immediately after starting work.

Key information required includes:

• Driver name and licence number
• Date and start time of each work period
• Odometer readings at the start and end of each work period
• Registration number of the vehicle
• Work and rest time entries in the correct format
• Two-up driver details where applicable (under section 299)

Section 298 specifically addresses the requirement to record odometer readings, making it an offence to fail to record this information. Odometer readings are critical because they allow enforcement officers to cross-reference diary entries against vehicle telematics and GPS data to verify accuracy.

What happens during an NHVR work diary check?

During an NHVR fatigue enforcement check—whether at a roadside inspection site or as part of a targeted compliance operation—an authorised officer will examine the driver's work diary alongside other documents. The officer typically checks:

• Whether the work diary is being carried when required
• Whether entries are complete, legible, and made in the correct format
• Whether work and rest hours comply with the applicable standard, BFM, or AFM limits
• Whether odometer readings are consistent with distances travelled
• Whether there are gaps, alterations, or signs of false entries
• The driver's licence and any BFM/AFM accreditation card

Officers may also cross-reference diary entries against telematics data, fuel card records, toll data, and weighbridge records. Discrepancies between the work diary and these independent data sources can trigger further investigation into the operator's scheduling and dispatch practices.

What is the operator's duty to ensure driver compliance?

HVNL section 264 places a direct obligation on employers, prime contractors, operators, and schedulers to ensure driver compliance with fatigue requirements. This is one of the most critical provisions for transport operators because it means that a driver's fatigue breach can also be the operator's breach.

Operationally, this duty requires operators to:

• Plan schedules and rosters that allow drivers to complete trips within legal work hour limits
• Provide sufficient time for mandatory rest breaks
• Verify that drivers are completing work diaries accurately and on time
• Monitor for patterns of non-compliance (e.g., repeated minor breaches, consistent late entries)
• Take corrective action when breaches are identified
• Maintain records that demonstrate active oversight of driver fatigue management

A operator who schedules a trip that is physically impossible to complete within standard hours has breached section 264 regardless of whether the driver actually exceeded the limit. The scheduling itself is the offence.

What are the record keeper obligations under the HVNL?

HVNL section 321 requires record keepers to maintain specific records relating to driver work and rest hours. In most operations, the operator is the record keeper. The records must be retained for the period specified in the national regulations and must be available for inspection by the NHVR or an authorised officer.

Section 322 sets out general requirements about drivers giving information to record keepers, including the requirement for drivers to submit work diary pages to the record keeper at regular intervals. Section 323 addresses what happens when a driver changes record keeper—the previous record keeper must transfer relevant records to the new record keeper.

For operators, the practical implication is that you must have a system to:

• Collect work diary pages from drivers on a regular cycle
• Store work diary records securely and retrievably
• Cross-check diary entries against scheduling and dispatch records
• Identify discrepancies and investigate them
• Produce records quickly during an audit or investigation

For more on building audit-ready evidence systems, see our guide on audit-ready compliance evidence for transport operators.

What are the offences for false or misleading work diary entries?

HVNL section 325 creates offences for false or misleading entries in work records, including work diaries. This provision applies to both drivers who make false entries and to any person who causes, induces, or permits a false entry to be made.

The offence is significant because it extends liability beyond the driver. If a scheduler pressures a driver to falsify a work diary entry to hide a breach—by altering rest times, omitting work periods, or backdating entries—the scheduler and the operator can both be charged.

Section 336 prohibits tampering with an approved electronic recording system, and section 336A requires reporting of tampering or suspected tampering with an electronic work diary. These provisions underscore that integrity of fatigue records is a fundamental compliance obligation.

How do fatigue breaches categorise under the HVNL?

HVNL section 222 defines categories of breaches for fatigue-related offences. Fatigue breaches are categorised based on severity, with higher categories attracting greater penalties. The categories reflect the level of risk created by the breach:

• Minor breaches involve small exceedances of work time or reductions in rest time that do not create an immediate safety risk but indicate a compliance failure.
• Substantial breaches involve more significant exceedances that elevate fatigue risk.
• Severe breaches involve major exceedances or complete disregard of fatigue requirements, creating serious safety risk.

The category of breach affects not only the penalty but also how the NHVR prioritises enforcement action. Severe breaches are more likely to trigger investigation into the operator's systems and other CoR parties.

How does extended liability work for fatigue offences?

The HVNL's extended liability provisions mean that parties other than the driver can be held liable for fatigue offences. If a driver commits a fatigue breach, the NHVR can investigate whether the operator, scheduler, consignor, or other party contributed to or failed to prevent the breach.

Extended liability is grounded in the shared responsibility principle (section 26A) and the primary duty (section 26C). If an operator cannot demonstrate that it took reasonable steps to prevent the breach—through scheduling systems, driver training, work diary monitoring, and corrective action—it may face prosecution alongside or instead of the driver.

For related enforcement signals, see our article on fatigue and driver diary checks: what recent NHVR enforcement signals mean for operators.

What records should operators retain to prove fatigue compliance?

To demonstrate fatigue compliance during an NHVR audit or investigation, operators should retain a comprehensive evidence set that goes beyond the work diary itself. The following records are critical:

• Work diary pages submitted by each driver, filed chronologically
• Rosters and schedules showing planned work and rest times for each driver
• Dispatch records including trip assignments, delivery times, and route details
• Telematics data including GPS tracking, speed, and vehicle movement records
• Driver communication records including messages about delays, rest breaks, and schedule changes
• Training records showing drivers have been trained in fatigue management and work diary completion
• Corrective action records demonstrating that identified breaches were investigated and addressed
• Fatigue management system documentation (for BFM/AFM accredited operators)

The ability to produce these records quickly and in an organised format is essential. An operator who cannot produce corroborating records when asked is in a significantly weaker position than one who can demonstrate systematic oversight.

For guidance on managing corrective actions and risk registers that support fatigue compliance, see our article on corrective actions and risk registers in transport compliance.

How does CoRGuard support fatigue compliance evidence?

CoRGuard is a Chain of Responsibility compliance software platform that helps transport operators manage fatigue compliance evidence through structured workflows. While the Electronic Work Diary is not yet live as a product feature, CoRGuard's current fatigue and driver diary check capabilities support operators in the following ways:

Centralised diary check records

CoRGuard allows operators to log driver work diary checks—whether conducted internally as part of routine oversight or following an NHVR roadside inspection. Each check record can capture the driver, date, diary period reviewed, any discrepancies identified, and corrective actions assigned. This creates an auditable trail that the operator is actively monitoring diary compliance.

Corrective action management

When a work diary check identifies a breach or discrepancy, CoRGuard's corrective action workflow ensures that the issue is documented, assigned, tracked, and closed out. This evidence of active remediation is critical for demonstrating that the operator is meeting its primary duty under section 26C.

Audit-ready evidence centralisation

Rather than scattering work diary records, schedules, and corrective actions across spreadsheets, email folders, and physical files, CoRGuard centralises fatigue compliance evidence in a single system. When the NHVR requests records, the operator can produce a structured, timestamped evidence set rather than scrambling to assemble documents.

Risk register integration

Fatigue-related risks—such as recurring breaches by a particular driver, routes that consistently pressure drivers to exceed hours, or patterns of late diary submissions—can be logged in CoRGuard's risk register. This supports the executive due diligence obligation under section 26D by providing visibility of systemic issues and tracking mitigation actions.

For operators preparing for the HVNL 2026 reform and compliance software transition, establishing these evidence workflows now builds the foundation for meeting the enhanced obligations that will take effect from 1 August 2026.

What should operators do next to prepare for fatigue enforcement?

Operators should take the following practical steps to strengthen fatigue compliance and evidence readiness:

1. Audit your current work diary collection process. Confirm that all drivers are submitting diary pages on the required cycle and that pages are being stored retrievably. Identify any gaps in your collection process.

2. Implement routine internal diary checks. Do not wait for an NHVR inspection to discover discrepancies. Schedule regular internal reviews of driver work diaries against schedules, dispatch records, and telematics data.

3. Document your scheduling controls. Ensure that your scheduling system demonstrably accounts for legal work and rest limits. Keep records of how schedules are built and reviewed for fatigue compliance.

4. Train drivers and schedulers. Confirm that all drivers understand work diary completion requirements and that schedulers understand their section 264 duty to ensure driver compliance. Retain training records.

5. Establish a corrective action process. When a fatigue breach is identified—whether internally or through an NHVR check—ensure there is a documented process for investigating, recording, and remediating the issue.

6. Centralise your evidence. Use a compliance management system like CoRGuard to bring diary checks, corrective actions, training records, and risk registers into a single, auditable platform. Contact our team to discuss how CoRGuard can support your fatigue compliance workflows.

Frequently asked questions

Who is legally responsible for work diary accuracy under the HVNL?

Under the HVNL, both the driver and the operator share responsibility for work diary accuracy. The driver must complete the diary accurately and immediately under sections 294–299. The operator, as record keeper under section 321, must collect and retain diary records. Under section 264, employers, prime contractors, operators, and schedulers must ensure driver compliance with fatigue requirements. Extended liability provisions mean that if the operator's scheduling or dispatch practices contributed to a breach, the operator can be charged alongside or instead of the driver.

How long must operators retain work diary records?

Work diary records must be retained for the period specified in the Heavy Vehicle (Fatigue Management) National Regulation. Operators should confirm the current retention period with the NHVR or their legal advisor, as retention obligations apply to both the driver's copy and the record keeper's copy. Failure to produce records during an audit or investigation can constitute a separate offence.

What happens if a work diary has missing or incorrect entries?

Missing or incorrect entries in a work diary can constitute an offence under the HVNL. Depending on the nature and severity of the omission, it may be categorised as a minor, substantial, or severe breach under section 222. If the entry is false or misleading, section 325 applies. The NHVR may issue an infringement notice, require corrective action, or initiate prosecution. Operators should have a process for identifying and addressing diary errors promptly through internal checks and corrective action workflows.

Can an operator be prosecuted for a driver's fatigue breach?

Yes. Under HVNL section 264, employers, prime contractors, operators, and schedulers have a duty to ensure driver compliance with work and rest requirements. If the operator's scheduling, dispatch, or oversight practices contributed to the breach, the operator can be prosecuted. The primary duty under section 26C and the shared responsibility principle under section 26A also support extended liability. Operators can defend themselves by demonstrating they took all reasonable steps to prevent the breach.

What is the difference between a written work diary and an electronic work diary?

A written work diary is a physical log book that drivers complete by hand, issued under HVNL section 340. An electronic work diary (EWD) is an NHVR-approved electronic recording system that automatically or semi-automatically records work and rest times. The HVNL contemplates EWDs in sections 314 and related provisions, including rules about tampering and malfunction reporting. CoRGuard's Electronic Work Diary feature is not yet live; current fatigue compliance workflows focus on written diary checks and operator evidence management.

What should an operator do if the NHVR requests work diary records during an investigation?

Operators should produce the requested records promptly and in an organised format. This includes the driver's work diary pages, associated scheduling and dispatch records, telematics data, training records, and any corrective action documentation related to the period under investigation. Having a centralised compliance management system like CoRGuard ensures that records can be assembled quickly and comprehensively, demonstrating active compliance management to the NHVR.

How does CoRGuard help operators manage fatigue compliance evidence?

CoRGuard supports fatigue compliance by centralising driver work diary check records, corrective actions, training records, and risk registers in a single platform. Operators can log diary checks, assign corrective actions for identified breaches, track resolution, and produce audit-ready evidence packages. While CoRGuard does not eliminate liability or guarantee compliance, it provides the structured workflows and evidence trails that operators need to demonstrate they are meeting their HVNL duties. Operators can learn more by reviewing the features page or contacting the CoRGuard team.
