About this Document

What Is a Chain of Responsibility Declaration?

A Chain of Responsibility (CoR) Declaration is a formal document used within the Australian transport and logistics industry. It acts as a written record that a specific party in the supply chain understands their legal obligations under heavy vehicle safety laws. While you might hear it called a "Party in the Supply Chain Declaration" or an "Executive Officer’s Declaration," the purpose remains the same. It confirms that the person signing knows they have a duty to ensure safety so far as is reasonably practicable.

For a long time, only the driver of a heavy vehicle was held responsible for offences like speeding or overloading. Australian law has shifted significantly. The focus is now on everyone who influences the transport task. This includes the scheduler who sets tight deadlines, the packer who loads the truck, and the business owner who pays for the fuel.

The declaration is the mechanism used to prove that these parties are aware of their responsibilities. It is not filed with the government. Instead, it is a commercial document kept between businesses. It is often used during the onboarding of subcontractors, owner-drivers, or new staff members. In some cases, it serves as a tick-box on a Consignment Note Template, acting as a legal acknowledgement that the goods being moved are safe and legal.

When to Use This Document

You should use a CoR Declaration whenever you engage with a new party in the heavy vehicle transport chain. This is particularly important if your business operations involve vehicles with a Gross Vehicle Mass (GVM) of more than 4.5 tonnes.

Onboarding Contractors and Owner-Drivers

If you run a logistics company or a construction firm and you hire a subcontractor to move materials, you must ensure they understand the law. Asking them to sign a declaration before they start work protects your business. It shows that you have taken reasonable steps to ensure they are compliant.

Employing Drivers

When you employ a driver directly, they should sign a declaration as part of their employment contract. This acknowledges that they understand they cannot be forced to break the law to meet a deadline. It also reminds them that they must refuse unsafe work.

Consignors and Consignees

You do not have to be a transport company to need this document. If you are a manufacturer sending out pallets of goods (a Consignor) or a warehouse receiving them (a Consignee), you have a legal duty. You should use a declaration when setting up contracts with transport providers. It clarifies that your loading times or unload facilities will not force the driver to speed or drive while fatigued.

The 4.5 Tonne Threshold

Many tradespeople assume these laws do not apply to them because they drive a ute. However, if you tow a trailer, you must calculate the combined GVM. If your ute weighs three tonnes and your trailer carries two tonnes of building supplies, your combined mass is five tonnes. You are now operating a heavy vehicle under the law. If you hire a subcontractor with this setup, or if you are the subcontractor, you are subject to Chain of Responsibility laws and should use a declaration.

Key Sections and Required Elements

A robust CoR Declaration must be more than a generic "I promise to be safe" statement. To be legally defensible and practically useful, it needs specific elements that address the nuances of the Heavy Vehicle National Law (HVNL).

Identification of the Party and Role

Liability under CoR laws is based on influence. Therefore, the document must clearly state who the signatory is and what role they play. You should include fields for the business name, ABN, and the specific role in the chain.

Common roles include:

  • Consignor: The person sending the goods.
  • Consignee: The person receiving the goods.
  • Loader: The person responsible for packing the vehicle.
  • Scheduler: The person setting the pickup and delivery times.
  • Driver: The person operating the vehicle.

Using checkboxes for these roles helps clarify exactly where the signatory's responsibility begins and ends.

Acknowledgment of Primary Duty

The document must explicitly reference Section 26C of the Heavy Vehicle National Law (or the equivalent state act for WA and NT). It should contain a mandatory clause where the signatory acknowledges they have a primary duty to ensure the safety of their transport activities. This cannot be vague. It must state that they understand this duty cannot be delegated to someone else.

Influence and Risk Factors

This is the most critical section for limiting liability. The law recognises that a packer cannot control how fast a driver drives on the highway. However, the packer can control the weight and stability of the load.

The declaration should include a matrix or a list of safety factors. The signatory must identify which risks they influence. These typically include:

  • Mass: Ensuring the vehicle is not overloaded.
  • Dimension: Ensuring the load does not overhang or exceed height limits.
  • Loading: Ensuring the load is restrained and won't shift.
  • Fatigue: Ensuring rosters allow for adequate rest breaks.
  • Speed: Ensuring schedules do not require speeding to meet deadlines.

Due Diligence Statement

For corporations and their executives, the law requires a demonstration of "due diligence." The declaration should ask the signatory to confirm they have taken active steps to prevent breaches. This is a checklist of actions, rather than just promises. It might ask the signatory to confirm they:

  • Have adequate resources to eliminate or minimise risks.
  • Have processes for receiving and considering information regarding incidents.
  • Have implemented compliant Induction Checklist Templates for staff.

Non-Delegable Duty Clause

The document must state that the duties under the HVNL are non-delegable. If a clause tries to say, "The subcontractor assumes all liability for safety," it is likely void. You cannot contract out of your safety responsibilities. The declaration should affirm that each party retains responsibility for their own influence over the transport task.

How to Write a Chain of Responsibility Declaration (Step by Step)

Drafting this document does not require you to be a lawyer, but you do need to follow a logical process to ensure it holds up if audited by the National Heavy Vehicle Regulator (NHVR).

Step 1: Identify the Applicable Law

First, determine which legislation applies to your operation. If you are operating in NSW, QLD, SA, TAS, VIC, ACT, or the NT, you will reference the Heavy Vehicle National Law (HVNL). If your operations are solely in Western Australia or the Northern Territory, you must reference the Road Traffic Act 1974 (WA) or the Traffic Act 1987 (NT). While the laws are similar, citing the correct act is essential for accuracy.

Step 2: Define the Parties Involved

Create a header section for the details of the declarant. This includes their full name, business name, ABN, and contact details. You should also include a field for the "Principal" or the entity requesting the declaration. This establishes the commercial relationship.

Step 3: List the Roles

Create a clear section where the signatory selects their role. Do not assume they are just a "driver." A scheduler has different risks than a loader. Be specific. You can use a dropdown menu or checkboxes in a digital document format.

Step 4: Draft the Acknowledgment Clauses

Write the core legal text. Use plain English. For example: "I acknowledge that I have a duty under the Heavy Vehicle National Law to ensure, so far as is reasonably practicable, the safety of my transport activities."

Follow this with the non-delegable statement: "I understand that I cannot transfer this duty to another party by contract or agreement."

Step 5: Create the Risk Matrix

Instead of a long block of text, use a table. List the safety hazards (Mass, Dimension, Loading, Fatigue, Speed, Maintenance) in the first column. In the second column, ask the signatory to tick "Yes" or "No" regarding whether they influence this hazard. In the third column, ask them to briefly describe the controls they have in place.

For example:

  • Hazard: Loading.
  • Do you influence this? Yes.
  • Controls: We use load restraints certified to the Load Restraint Guide 2018 and weigh every pallet before loading.

Step 6: Include the Executive Officer Section

If the signatory is a company director or CEO, add a specific section for "Executive Officer Due Diligence." This requires them to confirm they are actively monitoring the company's compliance. This is crucial because executive officers can be held personally liable for company failures.

Step 7: Add a Signature and Date Field

Finally, ensure there is a space for a physical or digital signature and the date. The date is vital because it proves the declaration was signed before the transport task began, not after an incident occurred.

Common Mistakes to Avoid

Many businesses treat the CoR Declaration as a tick-and-flick exercise. This approach can create more risk than it solves. Here are common pitfalls to avoid.

Using a "One Size Fits All" Template

Don't use the exact same document for a forklift driver as you do for a logistics manager. Their responsibilities are different. If a scheduler signs a declaration that focuses entirely on vehicle maintenance, they haven't actually declared their specific risks regarding fatigue and scheduling. Customise the document to the role.

Assuming the Document Absolves Liability

The biggest mistake is thinking that having a signed declaration means you are off the hook. The declaration is evidence of your awareness, not a shield. If you sign a declaration saying you will manage fatigue but then roster a driver for 14 hours straight without a break, the document will be used as evidence that you knew you were breaking the law.

Ignoring the Combined GVM

Tradespeople often get caught out here. They might sign a declaration for a truck but ignore their ute and trailer setup. Remember, if the combined GVM is over 4.5 tonnes, CoR applies. Ensure your declaration covers all vehicles used in your business operations that meet this threshold.

Failing to Update the Document

Laws and business operations change. If you update your Safety Policy Template or change your software systems, your declaration should reflect that. Using a declaration from five years ago that references old legislation or outdated procedures is not useful.

Vagueness

Avoid statements like "I will do my best to be safe." The law requires you to take "reasonable steps." The declaration should reflect this standard of care. It must be specific enough to show you have identified the actual risks in your supply chain.

Legal Considerations (AU)

Chain of Responsibility is a strict liability scheme in many respects. This means the prosecution does not always need to prove intent, only that a breach occurred. Understanding the legal framework is essential for all Australian business owners.

Heavy Vehicle National Law (HVNL)

The HVNL applies in most Australian states. Section 26C is the cornerstone. It imposes a primary duty on anyone in the supply chain to ensure the safety of transport activities. This is a broad, overarching duty. It means if you pressure a driver to meet an unrealistic deadline, and that driver speeds to meet it, you are liable.

Reasonable Steps Defence

The law provides a defence if you can prove you took "reasonable steps" to prevent the breach. Your CoR Declaration is a key piece of evidence in this defence. However, the declaration must be backed by action. If your declaration says you have training procedures in place, but you have no records of training ever occurring, the defence will fail.

Executive Officer Liability

Under Section 26D of the HVNL, executive officers of a corporation can be held personally liable for the company's breaches. This is similar to the personal liability directors face under the Corporations Act 2001 for insolvent trading. If you are a director or a "person who makes, or participates in making, decisions" that affect the whole or a substantial part of the business, you must exercise due diligence. You must acquire knowledge, understand the hazards, and ensure the company has resources to comply. An Executive Officer’s Declaration is your record of this commitment.

Western Australia and the Northern Territory

These jurisdictions have their own laws. The Road Traffic Act 1974 (WA) and the Traffic Act 1987 (NT) contain CoR provisions that mirror the national law. However, if your work crosses borders, which is common, the National Heavy Vehicle Regulator (NHVR) has jurisdiction. In these cases, it is best practice to reference the HVNL as the primary standard, as it covers interstate travel.

Work Health and Safety (WHS) Acts

CoR laws sit alongside WHS laws. The Model Work Health and Safety Act (adopted in most states) requires businesses to manage risks. A heavy vehicle incident is often a WHS incident. Your CoR Declaration should align with your broader WHS management system. Inconsistencies between the two can lead to confusion during an investigation by Safe Work or the NHVR.

Frequently Asked Questions (preview)

Do I need a lawyer to write a CoR Declaration? No, you do not need a lawyer. The NHVR provides templates and guides that are legally sound. However, you should ensure the document is tailored to your specific business activities.

Is this document required for every single job? Not necessarily. Once a subcontractor has signed a declaration at the start of a contract, it usually covers them for the duration of that agreement. However, you may need them to sign a new one if their role changes or if the laws change. For consignment notes, a declaration is often part of every single delivery transaction.

What happens if I refuse to sign? If you are a subcontractor and a principal asks you to sign a CoR Declaration, refusing may impact your ability to win the work. Principals ask for this document to protect their own liability. If you refuse to acknowledge your legal duties, they are unlikely to engage you.

Does this apply to owner-drivers? Yes. If you are an owner-driver, you are often the loader, scheduler, and driver all in one. You still need a declaration to show your clients that you understand your obligations.

How long should I keep these records? You should keep CoR Declarations for at least seven years. This is consistent with record-keeping requirements for tax and employment law. If an accident occurs years later, investigators will look for this historical data.
