Chain of Responsibility Offences:
What Everyone Involved with Heavy Vehicles Needs to Know
The trucking industry is the backbone of Australia’s economy, moving goods across the country every day. However, with that responsibility comes a strict set of regulations that truck drivers, companies, and everyone involved in the supply chain must follow. One of the most significant frameworks regulating this industry is the Chain of Responsibility (CoR) laws.
These laws don’t just affect drivers—they hold everyone in the transport chain accountable for ensuring that road safety and compliance rules are followed. Whether you’re a driver, owner, operator, scheduler, or loader, you could face serious penalties if these rules are breached. This article will break down what Chain of Responsibility offences are, what to do if you’re investigated or charged, and how Big Rig Law is here to help you navigate these regulations.

What Are Chain of Responsibility (CoR) Laws?
Chain of Responsibility (CoR) laws are a set of regulations under the Heavy Vehicle National Law (HVNL) designed to ensure that every party involved in the transport process takes responsibility for the safety of heavy vehicle operations.
Everyone involved with heavy vehicles — from the trucking company employing the driver, to the business dispatching or receiving goods—bears responsibility for the safety of the vehicle, the driver, and the load throughout the journey; this is their Primary Duty. Heavy vehicle drivers are not considered a party in the Chain of Responsibility (CoR) however, the HVNL imposes various other obligations that they and other employees in the heavy vehicle industry must adhere to.
- Employers and Operators: Ensuring vehicles are maintained and safe to operate.
- Schedulers: Making sure drivers have enough time to complete trips safely without breaching fatigue management rules.
- Loaders: Making sure loads are within the legal weight limits and properly restrained.
- Consignors and Consignees: Ensuring that goods are ready and transported in a compliant manner.
Common Chain of Responsibility Offences
The legal standard for compliance with the Primary Duty is whether a party has done everything reasonably practicable . The NHVR defines reasonably practicable as “how much trouble and expense you should go to so as to eliminate or minimise a risk, judged on what an ordinary, reasonable person would think was reasonable in the circumstance”.
CoR offences under the Heavy Vehicle National Law (HVNL) are taken very seriously so all parties in the supply chain must be aware of their role in the chain. Here are some CoR offences as they relate to employers:
1. Overloading
- Primary Duty: Employers have a primary duty to ensure, so far as is reasonably practicable, the safety of their transport activities. This includes ensuring that vehicles are not overloaded.
- Executive Due Diligence: Executives must exercise due diligence to ensure that their business complies with its primary duty. This means implementing systems and processes to prevent overloading and regularly checking that these measures are effective.
- Penalties: Overloading offences can result in significant penalties, including fines and court-imposed penalties. The penalties are calculated based on the total overladen amount, and they increase with each percent the overload exceeds the allowable weight.
- Reasonable Steps Defence: Employers can defend against overloading offences by demonstrating that they took all reasonable steps to prevent the contravention. This includes accurate weight measurements, using weighbridges, and implementing strict load management procedures.
- Enforcement: Enforcement officers can issue infringement notices for minor breaches, which can be paid or contested in court. For more serious breaches, a Court Attendance Notice may be issued, requiring the person to appear before a magistrate.
2. Fatigue Management
- Primary Duty: Employers have a primary duty to ensure, so far as is reasonably practicable, the safety of their transport activities. This includes managing driver fatigue to prevent accidents caused by tired drivers.
- Executive Due Diligence: Executives must exercise due diligence to ensure that their business complies with its primary duty. This means implementing systems and processes to manage driver fatigue effectively.
- Driver Responsibilities: While drivers are not considered parties in the CoR, they have specific duties under the HVNL to comply with work and rest hour requirements. Companies must support drivers in meeting these requirements.
- Risk Management: Employers must identify and manage risks associated with driver fatigue. This includes implementing fatigue management policies, providing training to drivers, and monitoring compliance with work and rest hour requirements.
- Penalties: Failure to manage driver fatigue can result in significant penalties, including fines and court-imposed penalties. Employers must take all reasonable steps to prevent driver fatigue to avoid these penalties.
- Reasonably Practicable: Employers can defend against CoR allegations by demonstrating that they did everything "reasonable practicable" to comply with their CoR obligations.
3. Vehicle Maintenance
- Regular Inspections: Employers must conduct regular inspections and maintenance of their vehicles to ensure they are in safe working condition.
- Compliance with Standards: Vehicles must comply with all relevant standards and regulations, including those related to brakes, tires, lights, and other safety features.
- Record Keeping: Employers must keep detailed records of all maintenance activities, including inspections, repairs, and servicing.
- Addressing Defects: Any identified defects must be promptly addressed and rectified to ensure the vehicle remains safe to operate.
- Driver Training: Employers should provide adequate training to drivers on vehicle maintenance and the importance of reporting any issues.
4. Load Restraint
Employers must ensure that loads are properly secured to prevent hazards on the road. Load restraint is a critical aspect of the CoR under the HVNL. Proper load restraint ensures that loads are securely fastened to prevent shifting or falling during transport, which can cause accidents and hazards on the road.
