Chain of Responsibility (CoR)
Chain of responsibility (CoR) is an Australian heavy vehicle law concept that extends safety accountability across the whole transport supply chain. Everyone who influences how a heavy vehicle is loaded, scheduled, and driven shares a duty to ensure safety, not just the driver.
Chain of responsibility (CoR) is a principle in Australia’s Heavy Vehicle National Law that makes every party who influences a transport task legally accountable for safety, not only the driver. Parties such as operators, schedulers, consignors, consignees, loaders, and packers each have a duty to ensure, so far as is reasonably practicable, the safety of their transport activities. It applies to risks like fatigue, speed, mass, dimension, and load restraint.
Why it matters
CoR recognises that unsafe outcomes on the road often originate off the road, in tight delivery schedules, overloading, or pressure on drivers. By placing duties across the supply chain, it prevents responsibility from resting solely with drivers. Businesses that consign, receive, load, or schedule freight need systems and records to demonstrate they have taken reasonable steps to manage transport safety risks.
How MapTrack helps
MapTrack helps transport-related businesses meet CoR duties by keeping vehicle inspection, maintenance, and compliance records that show heavy vehicles and equipment are roadworthy and that reasonable safety steps have been documented.

Frequently asked questions
Who is covered by chain of responsibility?
CoR covers parties in the heavy vehicle transport chain who can influence safety, including the operator, prime contractor, employer, scheduler, consignor and consignee, packer, loader and unloader, and loading manager. A single business can hold more than one of these roles. The driver remains responsible too, but CoR ensures off-road decision-makers share accountability for transport safety.
What risks does chain of responsibility apply to?
CoR applies to the safety risks associated with heavy vehicle transport, including driver fatigue, speed compliance, vehicle mass and dimension limits, and securing and restraining loads. Each party must take reasonable steps within its control to manage these risks, for example by setting realistic schedules, not overloading vehicles, and ensuring loads are properly restrained before transport.

Fatigue Management
Fatigue management is the practice of controlling the risk that tired drivers pose to road safety. For fatigue-regulated heavy vehicles in Australia, it involves complying with work and rest hour limits, keeping accurate records such as a work diary, planning realistic schedules, and recognising the signs of fatigue. It is part of the chain of responsibility, so the duty extends beyond drivers to operators and schedulers.
National Heavy Vehicle Regulator (NHVR)
The National Heavy Vehicle Regulator (NHVR) is the Australian body responsible for administering the Heavy Vehicle National Law (HVNL), which applies to heavy vehicles over 4.5 tonnes gross vehicle mass in participating states and territories. The NHVR oversees areas such as vehicle safety and standards, fatigue management, mass and dimension limits, accreditation schemes, and access permits for restricted routes.
Fleet Management
Fleet management is the administration of an organisation’s vehicles and mobile plant, including acquisition, maintenance, fuel management, driver compliance, GPS tracking, and disposal. It covers light vehicles, heavy vehicles, trailers, mobile plant, and any other registered or unregistered mobile assets. Modern fleet management relies on telematics, GPS tracking, and software platforms to optimise operations and reduce costs.
Pre-Start Inspection
A pre-start inspection is a systematic check performed on plant, equipment, or vehicles before each use or shift to identify defects, damage, or unsafe conditions. It typically follows a standardised checklist covering safety-critical items such as brakes, steering, lights, tyres, guards, fluid levels, and warning devices. Pre-start inspections are a legal requirement under workplace health and safety regulations in Australia and are similarly required in other jurisdictions, including OSHA equipment inspection requirements in the United States and PUWER requirements in the United Kingdom.
Compliance Management
Compliance management in asset-intensive industries is the systematic process of ensuring that equipment, operations, and personnel meet all applicable regulatory, safety, environmental, and contractual requirements. It encompasses tracking inspection due dates, certifications, licences, safety checks, environmental obligations, and industry-specific standards. Compliance management requires both proactive scheduling and thorough record-keeping.
