Quick answer
Chain of Responsibility (CoR) means safety on the road is a shared duty across the whole supply chain, not the driver’s alone. For transport operators, it means you must manage the risks your activities create — fatigue, speed, mass, dimension, loading, and vehicle maintenance — so far as is reasonably practicable, and be able to show how.
What CoR is
CoR sits within the Heavy Vehicle National Law, administered by the NHVR in participating states and territories. It holds every party who influences a transport task accountable for safety outcomes.
The primary duty
Ensure the safety of your transport activities so far as is reasonably practicable. That means proactively identifying risks and putting controls in place — not just reacting after something goes wrong.
Key risk areas for operators
- Fatigue — realistic schedules and rest compliance
- Speed — no pressure or incentives that encourage speeding
- Mass, dimension and loading — correct, secure, legal loads
- Vehicle standards — maintenance and roadworthiness
How to stay compliant
Document your CoR policies, assess your risks, build practical controls into scheduling and loading, keep records, and train your people so the duty is understood across the business.
