Under Chain of Responsibility (CoR) law, liability for a mass, dimension or loading breach is never limited to the driver. The consignor, packer, loader, scheduler and operator can each be prosecuted if their part of the chain contributed to the breach — with penalties reaching into the millions, and enforcement tightening once the HVNL reform commences on 1 August 2026.
- The CoR “primary duty” covers every party in the supply chain, not just the person behind the wheel
- Real case: NHVR fined a Melbourne scrap metal company $180,000, plus its three directors up to $8,500 each, after 69 mass limit breaches over two years (July 2024)
- One intercepted vehicle in that case was loaded at 120.42% of its legal mass limit — a “severe risk breach”
- Category 1 (most serious) breaches carry base statutory penalties up to $300,000 (individual, plus up to 5 years’ imprisonment) and up to $3 million (corporation) — indexation lifts current amounts higher
- The amended HVNL commences 1 August 2026 with no grace period and a signalled tougher prosecution posture
- A Safety Management System becomes mandatory for HVA scheme operators under the reform, with wider adoption expected
- FMS delivers a non-accredited CoR Awareness course and the nationally accredited TLIF0009 course, both online, nationwide
Who exactly is liable when a load exceeds its mass limit?
CoR law runs on a “primary duty” — every party in a heavy vehicle transport task must eliminate or minimise public safety risks connected to their part of the job, so far as reasonably practicable. For a mass or loading breach, that duty is not confined to the driver or operator. It extends to whoever packed the goods, loaded the vehicle, consigned the freight or scheduled the job — because a mass breach is often the downstream result of a decision made before the truck left the facility.
What counts as a “loading” or “packing” breach under CoR?
Mass and loading breaches fall into a few recurring patterns: a vehicle loaded above its permitted gross or axle mass, freight loaded without proper mass distribution, and dimension breaches where a load exceeds permitted width, height or length. The HVNL uses a risk-based classification: a load at 120% or more of its prescribed mass limit is a “severe risk breach” — the most serious mass category NHVR applies when assessing enforcement action.
Which parties carry a specific duty, and what does failure look like?
| CoR party | Specific mass/loading duty | Example failure that triggers liability |
|---|---|---|
| Consignor | Must not direct a load known, or reasonably suspected, to exceed mass or dimension limits | Booking freight without verifying declared weight |
| Packer | Must pack goods so the load stays within mass limits and is safely contained | Under-declaring pallet weight or a dense load |
| Loader | Must load within mass limits, distributed properly across axle groups | Overloading one axle or loading heavy items forward of the group |
| Scheduler | Must not schedule a job that pressures an outcome that breaches limits | Booking partial loads into one run without checking cumulative mass |
| Operator | Must implement fleet-wide systems to manage mass and loading compliance | No weighbridge checks or mass-management system |
| Driver | Must not drive a vehicle known, or suspected, to breach mass limits | Departing after being told the load is over limit |
What penalties actually apply for mass and loading breaches?
Penalties escalate with breach severity. The figures below are the base statutory maximums set under the HVNL; annual indexation lifts the actual amounts higher.
| Offence category | Maximum penalty — individual | Maximum penalty — corporation |
|---|---|---|
| Category 1 (most serious / reckless conduct exposing a person to death or serious injury) | Up to $300,000 or up to 5 years’ imprisonment, or both | Up to $3 million |
| Category 2 (substantial risk to public safety) | Up to $150,000 | Up to $1.5 million |
| Category 3 (risk to public safety) | Up to $50,000 | Up to $500,000 |
These figures sit on top of prosecution costs and any operating restrictions, and apply to each party found in breach — a company and its directors can be fined separately for the same underlying breach, as the case below shows.
Has anyone actually been prosecuted for this?
Yes. In July 2024 the NHVR prosecuted a Melbourne scrap metal company after officers intercepted a heavy vehicle loaded at 120.42% of its prescribed mass limit. The investigation uncovered 69 mass limit breaches over two years, 24 of them severe risk breaches. The company pleaded guilty to a Category 1 offence — the most serious under the HVNL — with a conviction recorded and a $180,000 fine. Its three directors separately pleaded guilty to failing to exercise due diligence, fined $8,500, $7,000 and $7,000 respectively.
What changes on 1 August 2026, and why does it matter now?
The amended Heavy Vehicle National Law commences 1 August 2026, with no grace period — the most substantial CoR update since the HVNL began. NHVR has signalled a tougher prosecution posture for repeat or systemic non-compliance. A headline change: a documented, audited Safety Management System becomes mandatory for Higher Volume Access (HVA) scheme operators, with broader adoption encouraged industry-wide. For businesses managing mass and loading compliance informally, the reform date is a hard deadline, not a soft target.
Which FMS course covers this duty?
FMS delivers two CoR options online, nationwide: a non-accredited CoR Awareness course for a broad induction to primary duty obligations, and the nationally accredited TLIF0009 course for roles needing a recognised qualification.
Frequently asked questions
Who is liable if a truck is overloaded under Chain of Responsibility law?
Everyone whose actions or omissions could cause the breach — not just the driver. This includes the consignor, packer, loader, scheduler and operator.
Can a business be prosecuted even if the driver was the one who got weighed?
Yes. NHVR investigations routinely extend beyond the intercepted vehicle to the systems and procedures of every party in the chain. In the 2024 scrap metal case, the company and its three directors were all prosecuted, not just the driver.
What is a “severe risk breach” for mass?
A load at 120% or more of its prescribed mass limit — the most serious mass category under the HVNL’s risk-based breach framework.
What are the maximum penalties for a mass or loading breach?
Category 1 (most serious) breaches carry base statutory penalties of up to $300,000 for an individual (or up to 5 years’ imprisonment) and up to $3 million for a corporation. Category 2 and Category 3 breaches are lower but still substantial. Indexation lifts the actual current amounts higher.
What changes for CoR mass and loading duties from 1 August 2026?
The amended Heavy Vehicle National Law commences 1 August 2026 with no grace period. NHVR has signalled a more active prosecution posture, and Safety Management Systems become mandatory for Higher Volume Access scheme operators, with broader adoption expected.
Does a Safety Management System have to be accredited for every business?
Not automatically. A documented, audited Safety Management System is mandatory specifically for HVA scheme operators; other parties are still expected to have reasonable systems in place to meet their primary duty.
Is CoR training compulsory for loaders and schedulers?
The HVNL doesn’t mandate a specific course, but it does require reasonable steps and due diligence to prevent breaches — recognised CoR training is one of the clearest ways to demonstrate that.
Which FMS course covers mass and loading duties under CoR?
FMS delivers a non-accredited CoR Awareness course and the nationally accredited TLIF0009 course, both online and nationwide, covering the primary duty including mass, dimension and loading obligations.
