Chain of Responsibility (CoR) is the part of the Heavy Vehicle National Law (HVNL) that makes every business influencing a heavy vehicle’s transport activities responsible for safety, not just the driver.
Chain of Responsibility (CoR) Compliance: Turning Heavy Vehicle Checks into Evidence
Under CoR, the question after an incident or audit is rarely “did you have a checklist?” It is “what did you do about what the checklist found?” Operators, schedulers, consignors, loaders and executives all share responsibility for heavy vehicle safety, and each needs to show the steps they took were reasonable.
DIGI CLIP is an Australian-built mobile checklist and inspection platform designed to help transport and logistics businesses capture that evidence in the field: pre-starts, load checks and fault reports on a phone or tablet, with defects moved into the Action Log where they are assigned, resolved and verified.

What changed in 2026
2026 has been a big year for heavy vehicle regulation. Two changes matter most for CoR parties:
- The 2026 Master Code (January 2026). The NHVR released an updated registered industry code of practice, replacing the 2018 Master Code. It gives practical guidance on identifying and controlling risks across transport activities. See the NHVR 2026 Master Code.
- The amended HVNL (1 August 2026). The NHVR describes this as the most significant overhaul of heavy vehicle regulation since the law was introduced, shifting towards proactive risk management and shared responsibility. Changes include the new Heavy Vehicle Accreditation (HVA) scheme replacing NHVAS, and a Safety Management System Standard. See NHVR – HVNL reform implementation.
For most businesses the practical message is the same: regulators expect you to know your risks, have controls in place, and hold records that show those controls working day to day.
Who is in the chain
The NHVR lists the parties in the Chain of Responsibility as the following. A single business can hold several of these roles at once.
| CoR party | Typical example | Evidence that can help |
|---|---|---|
| Employer of a heavy vehicle driver | Transport company | Pre-start records, fitness-for-duty declarations, training records |
| Prime contractor of a self-employed driver | Business engaging owner-drivers | Contractor inductions, vehicle condition checks |
| Operator | Business controlling the vehicle’s use | Pre-starts, defect reports and verified repairs |
| Scheduler | Dispatcher or transport planner | Documented schedule reviews and risk checks |
| Consignor and consignee | Manufacturer, retailer or receiver | Site safety and loading dock inspections |
| Packer | Warehouse packing goods | Packing and labelling checks |
| Loading manager, loader and unloader | Distribution centre or yard team | Load restraint, mass and loading checklists with photos |
Drivers have their own duties under the HVNL but are not a CoR party unless they also perform one of these roles. Source: NHVR – Chain of Responsibility.
The primary duty and executive due diligence
Every CoR party has a primary duty to keep its transport activities safe, so far as is reasonably practicable. “Reasonably practicable” means weighing the likelihood and severity of harm against what can reasonably be done about it, so the right controls depend on your operation.
Executives, such as directors and senior managers, have a separate due diligence duty. In practice that means staying informed about transport safety, understanding the risks, making sure resources and processes are in place, and checking those processes are actually used. The NHVR’s regulatory advice on the primary duty explains both duties in detail.
A completed checklist shows a task happened. It doesn’t show what happened next.

What CoR evidence looks like in practice
Auditors and investigators look for a system that works, not paperwork that exists. The table below shows common CoR risk areas and the kind of records DIGI CLIP is designed to capture.
| Risk area | Example check | What DIGI CLIP records |
|---|---|---|
| Vehicle standards and maintenance | Daily heavy vehicle pre-start | Time-stamped answers, photos of defects, the driver and vehicle, and the linked Action Log item |
| Mass, dimension and loading | Load restraint and loading checklist | Photos of the secured load, checker sign-off and any issues raised |
| Fatigue and fitness for duty | Fitness-for-duty declaration before a shift | Driver declaration and signature, with a flag if the answer needs follow-up |
| Sites and loading docks | Loading dock or yard safety inspection | Hazards found, who was assigned to fix them and when they were closed out |
| Executive oversight | Monthly review of open and overdue actions | Dashboards, overdue escalation emails and PDF or Excel exports for management reporting |
DIGI CLIP is not an electronic work diary and does not replace your fatigue, accreditation or maintenance systems. It is designed to sit alongside them as the place where checks are completed and every defect is tracked to close-out.
How to set up CoR checks in DIGI CLIP
- Map your roles and risks: list which CoR roles your business holds and the transport activities that carry the most risk.
- Choose or build your forms: start from a heavy vehicle pre-start, load restraint or site inspection template and adjust it to your fleet.
- Make “No” answers count: require a comment and photo when an item fails, so every defect is recorded clearly at the vehicle.
- Send defects to the Action Log: configure failed items to create actions with an owner and due date, and overdue escalation by email.
- Verify close-out: use one-step or two-step close-out (implemented, then closed out) so fixes are checked, not just ticked off.
- Review and report: use dashboards and exports to show managers and executives what was found, what was fixed and what is still open.
Example scenario: from a missed defect to a verified fix
This is an illustrative scenario showing how DIGI CLIP is designed to work. It is not a specific customer case study.
A regional carrier runs a mixed fleet of prime movers and rigid trucks. Pre-starts are done on paper, and when a driver notes a worn trailer brake hose, the sheet sits in the depot office until the end of the week. Nobody can later show when it was reported or when it was fixed.
With DIGI CLIP configured for their fleet:
- Find it: the driver answers “No” on the brake hose item, adds a photo and a comment, and submits from the cab.
- Fix it: the defect creates an action in the Action Log, assigned to the workshop with a due date. If it goes overdue, the manager gets an email.
- Prove it: the workshop records the repair and a supervisor verifies close-out, linked back to the original pre-start.
If an auditor asks what happened to that defect, the answer is one search away.

Frequently asked questions
What is Chain of Responsibility (CoR)?
Chain of Responsibility is part of the Heavy Vehicle National Law. It makes every business that influences a heavy vehicle’s transport activities, such as operators, schedulers, consignors, packers and loaders, responsible for safety, not just the driver.
What is the primary duty under CoR?
Each CoR party has a primary duty to keep its transport activities safe, so far as is reasonably practicable. What is reasonably practicable depends on the risks in your operation and what can reasonably be done to control them.
What changed with the HVNL in 2026?
The NHVR released the 2026 Master Code in January 2026, and the amended Heavy Vehicle National Law commenced on 1 August 2026. The reforms focus on proactive risk management and include the new Heavy Vehicle Accreditation scheme. Check the NHVR website for the details that apply to your business.
Can DIGI CLIP make my business CoR compliant?
No software can do that on its own. DIGI CLIP is designed to help you complete checks consistently, capture evidence and track defects through to verified close-out, which can support the systems and records your CoR obligations call for.
Is DIGI CLIP an electronic work diary?
No. DIGI CLIP is a mobile checklist and inspection platform. It can capture fitness-for-duty declarations as part of a pre-start, but it does not replace an approved work diary or fatigue management system.
How long should CoR records be kept?
Record-keeping periods depend on the type of record and your own obligations. Many businesses keep inspection and maintenance records for several years. DIGI CLIP stores submitted forms in the cloud with search by form, person, date range and keyword.
Conclusion: make CoR evidence part of the everyday
CoR rewards businesses that can show their safety systems working, not just written down. When pre-starts, load checks and site inspections feed straight into assigned, verified actions, the evidence builds itself as the work gets done: defect found, fix assigned, close-out verified.
