About Chain of Responsibility

Chain of Responsibility (CoR) is a legal framework under Australia's Heavy Vehicle National Law (HVNL) that extends safety duty beyond drivers and operators to every party who influences a heavy vehicle transport task — including consignors, loaders, schedulers, and executives. Each party must take all reasonable steps to ensure the transport task is performed safely.

Under the HVNL, responsibility is shared. If your business decisions affect how a heavy vehicle is operated — scheduling, loading, consigning, dispatching, or managing — you hold a duty alongside the driver and operator. The framework covers speed management, fatigue, mass, dimension, load restraint, and vehicle standards.

The six defined parties in the Chain of Responsibility are: consignors, consignees, packing entities, loading entities, drivers, and operators. The principle of shared responsibility means that no single party can avoid accountability simply because they are not behind the wheel. Regulators can investigate and take enforcement action against any party whose conduct or omissions contributed to a breach.

MAEZ helps operators and related parties understand who holds a duty, what each duty requires, and where evidence of reasonable steps should be maintained to demonstrate that safety obligations have been met. MAEZ serves businesses in Sydney, Melbourne, Brisbane, and throughout Australia.

Under the HVNL, duty holders include any party across the supply chain whose decisions influence a heavy vehicle transport task. The law is deliberately broad—influence, not job title, determines accountability.

Duty holders can include operators, employers, prime contractors, schedulers, consignors, consignees, loading managers, loaders, unloaders, packers, and executives.

If commercial decisions, scheduling pressure, loading practices, or contracting arrangements affect how a heavy vehicle is used on the road, CoR obligations may apply. Each role carries different control expectations and evidence requirements.

The HVNL establishes a shared responsibility model. Duty holders must take all reasonably practicable steps to prevent breaches relating to speed, fatigue, mass, loading, dimension, and vehicle standards.

In practice, this means:

• Not requesting, directing, or entering into contracts that would cause or encourage a breach
• Implementing systems that identify and manage transport safety risks
• Keeping records that demonstrate reasonable steps were taken
• Reviewing controls to confirm they are working, not just sitting on a shelf

Executive officers of a legal entity also carry a personal due-diligence duty. They must actively ensure the business has appropriate systems and must know whether those systems are actually functioning.

MAEZ helps Australian transport and supply-chain businesses turn broad HVNL obligations into practical, role-based compliance. We focus on the gaps that matter most before an auditor or regulator finds them.

Our approach covers:

• Find — Identify what is exposed across CoR, HVNL, WHS, NHVAS, training, and SMS frameworks
• Fix — Build Safety Management System controls around how the transport business actually runs
• Prove — Use structured records, reminders, audits, and evidence workflows where software is needed

Where the business needs a Safety Management System platform, CoRGuard supports records, fatigue and driver diary checks, maintenance, audits, document control, inductions, corrective actions, and evidence reporting. MAEZ defines the risk, obligations, and implementation pathway; CoRGuard provides the structured evidence workflow.

For training, MAEZ provides the advisory and risk pathway, while Chain of Responsibility courses are delivered through cortraining.com.au.

CoR is relevant to anyone who influences a heavy vehicle transport task — not just drivers and fleet managers. This includes:

• Owner-operators and transport managers
• Executives and company directors with personal due-diligence duties
• Consignors and consignees whose freight demands affect scheduling and loading
• Loaders, unloaders, and packers who control mass, dimension, and restraint
• Schedulers and prime contractors who set time pressures

If your role touches the transport supply chain, understanding your CoR obligations is essential. For role-specific guidance, explore Chain of Responsibility Training for Executives and Managers or contact MAEZ for a practical compliance review.
