What Is Corporate Derivative Liability? | SAPOL vs Furler Family Trust Case Study

The case involved a Fleurieu Peninsula tourist company that operated small minibuses for sightseeing tours. The company did not initially understand that its minibuses were classified as heavy vehicles under the relevant legislation.

In May 2019, the South Australian State Government introduced increased penalties for heavy vehicles travelling on the South-Eastern Freeway. These penalties followed recommendations by the South Australian Coroner after horrific incidents in which out-of-control heavy vehicles had claimed innocent lives.

A company employee drove the minibus on the South-Eastern Freeway at 73 km/h, believing the vehicle fell under the 4.5-tonne threshold and could travel up to 90 km/h. The driver thought he was doing 17 km/h under the speed limit. In reality, the vehicle was classified as a heavy vehicle and was subject to a lower speed restriction.

After the offence was detected and an expiation notice was issued to the Furler Family Trust, the managing director confirmed the fine with the fines call centre. The fine was confirmed at $26,096 — substantially higher than it needed to be — simply because the business could not nominate the driver of the vehicle on the day of the offence.

Had the driver been nominated, the fine for the driver would normally have been $1,036 plus six demerit points and an automatic six-month licence disqualification for a first offence. Instead, because the business could not identify who was driving, the penalty fell on the company at the corporate rate — more than twenty-five times the individual amount.

The managing director, Mr Coull, said:

"My employee thought he was doing 17km under the speed limit, and he normally drives a slightly smaller bus that isn't subject to this new law. Of course, as a small family business owner, we value our employees and also feel in part responsible for not making sure he knew the new legislation."

This statement captures the core of derivative liability: the business failed to ensure its driver understood the legal classification of the vehicle and the applicable speed limits. The gap was not in the driver's intent — it was in the company's systems for communicating and verifying compliance.

In this case, the owners of the Fleurieu tourist company should have known about the risks within their organisation and allocated suitable budget and resources to prevent a driver speeding. The concept of corporate derivative liability places responsibility on executives and managers to ensure their business understands its obligations and actively manages compliance.

Key obligations for executives include:

• Knowing which vehicles in the fleet are classified as heavy vehicles under the HVNL
• Ensuring drivers are briefed on route-specific restrictions and changes to penalties
• Maintaining records that allow the business to identify who was driving a vehicle on a given day
• Allocating budget for training, systems, and compliance support proportional to the risk
• Not waiting for an incident or enforcement action to surface gaps

For a broader understanding of how these obligations fit within the wider Chain of Responsibility framework, the same principle applies across every party in the supply chain — not just drivers and operators.

A $26,096 fine is a serious amount for any business to absorb. In many cases, businesses that engage MAEZ are potentially facing court action as a result of a driver or operator within their supply chain. The cost of preventing these outcomes is far lower than the cost of the penalties themselves.

There are 341 Heavy Vehicle National Law penalties, which can exceed $100,000 for a business with a transport task or one that influences a transport task. MAEZ has helped dozens of businesses address risks found through gap analysis that would have exposed them to serious financial penalties — easily exceeding a fine of $26,000.

Training can be inexpensive and practical. MAEZ safety training has been rolled out to many businesses and hundreds of employees digitally, offering flexibility for staff to complete it in their own home or workplace. Chain of Responsibility training helps staff understand their obligations and reduce legal liability before an incident forces the issue.

MAEZ helps Australian businesses turn Chain of Responsibility, HVNL, WHS, transport safety, and chartered risk obligations into practical training, advisory, audit, and implementation pathways. For businesses that need to build or verify their compliance position, MAEZ offers:

• Identification of what is exposed before an auditor or regulator finds it
• Gap analysis to surface risks that could lead to serious financial penalties
• Chain of Responsibility training to help staff understand their obligations and reduce legal liability
• CoR consulting to review controls, evidence, and SMS gaps that matter most
• Practical implementation support to build Safety Management System controls around how the business actually runs

Where software is the right next step, CoRGuard supports the evidence workflow — covering records, reminders, diaries, audits, document control, inductions, corrective actions, and evidence review.

The Furler Family Trust case highlights several lessons that apply to any business with a transport task:

Know your vehicle classifications

A minibus can be a heavy vehicle under the HVNL even if it does not look like a traditional truck. Businesses must verify the GVM of every vehicle in their fleet and understand which legislative thresholds apply.

Maintain driver identification records

The fine in this case ballooned because the business could not nominate the driver. Robust roster, logbook, and diary systems allow a business to identify who was driving on any given day — and reduce penalty exposure accordingly.

Brief staff on route-specific rules

Speed limits and penalty regimes can change by road and by jurisdiction. Drivers need to be told when new restrictions apply to routes they use regularly.

Invest in training before enforcement arrives

Chain of Responsibility training for executives and managers helps leaders understand their personal exposure and build the systems that prevent breaches. The cost of training is a fraction of even a single HVNL penalty.
