Why fitness-to-drive forms won't protect your transport business
A declaration is not a control
A signed fitness-to-drive form records a driver's claim that they are fit to drive — it does not verify it. Under the Heavy Vehicle National Law, every party in the Chain of Responsibility must take all reasonably practicable steps to ensure safety. A form alone does not discharge that duty and may even demonstrate awareness of a risk without any real control over it.
If a crash occurs and drugs or alcohol are found in the driver's system, the investigation does not stop with the driver. The employer, the loader, and their employers may all be investigated for criminal offences, including allowing an unfit person to drive a heavy vehicle.
The HVNL defines a heavy vehicle as one with a Gross Vehicle Mass of 4.5 tonnes or more, whether or not it is laden. The same zero-tolerance drug and alcohol standard that applies to provisional (P plate) drivers applies to every heavy vehicle driver. For more on how duties extend across the supply chain, see About Chain of Responsibility.
Three deaths in three days: the reality of heavy vehicle crashes
Early in a new financial year, three people had already died in heavy vehicle related crashes within three days. Others were taken to hospital with injuries. One incident stood out: a truck driver refused an oral fluid sample at the scene of a crash and will now face court as a result.
Every accident is a tragedy. People are affected, injured, or worse. But everyone in the supply chain may share responsibility for any of those trucks involved in these crashes.
There is nothing like the present to ensure an accident doesn't happen on your watch, without warning. Accidents are unexpected, and they can haunt you for the rest of your life. The question is whether your safety system is actually working before that moment arrives.
What the law requires of heavy vehicle drivers after a crash
Legislation requires that any driver of a heavy vehicle must not drive under the influence of drugs or alcohol. That means an alcohol reading of zero — the same standard expected of a provisional driver.
After an incident occurs, the driver must submit a fluid sample to test for drugs and/or alcohol. Refusing that sample is itself an offence.
If drugs or alcohol are found in the driver's system, the investigation does not stop with the driver. The driver's employer, and potentially the person who loaded the vehicle and their employer, may also be investigated for criminal offences. Those offences may include allowing a person affected by drugs and/or alcohol to drive a heavy vehicle.
Under the HVNL, when a court decides whether a driver of a fatigue-regulated heavy vehicle was fatigued, it may consider what is commonly understood as being fatigued, the causes and signs of fatigue, any relevant body of fatigue knowledge, and any other prescribed matter. A driver is impaired by fatigue if their ability to drive safely is affected.
Why a signed fitness-to-drive form is not enough
A declaration does not verify fitness — it records a claim
Many operators say to themselves, "We're fine, we have our drivers sign a fitness-to-drive form." This is not good enough, and it will not save you from a potential prosecution.
Whoever came up with the fitness-to-drive declaration had great intentions, but a form cannot stop someone from declaring they are okay when they are not. It does not verify fitness; it records a claim of fitness.
If you find yourself sitting in front of a prosecuting barrister asking, "How do you ensure that someone who was unfit to drive was fit to fill in a fitness-to-drive declaration?" — then you have not yet thought through your ability to ensure a duty of care for the people who work for you, or those who carry your goods.
The deeper risk
There is a school of thought that relying on a declaration form could actually land you in deeper water, because it may demonstrate awareness of the risk without demonstrating any real control over it. A regulator may ask: you knew the risk existed, you had the driver sign a form, but what did you actually do to manage it?
Everyone in the chain is liable — even if you don't pay the driver
Everyone in the chain is liable, even if you do not pay the driver's wages directly. It is not acceptable to move your obligations on through a declaration form for someone else to fill in, nor to contract your responsibility out to another entity.
The duty stays with you. This is the core of Chain of Responsibility under the HVNL: each party in the supply chain must take all reasonably practicable steps to ensure safety. A piece of paper signed by a driver does not discharge that duty.
If you influence a transport task — as a consignor, consignee, loader, scheduler, manager, or contractor — the obligation to ensure the driver is fit to drive sits with you too. Practical Chain of Responsibility consulting can help you identify what that obligation means for your specific role.
How MAEZ helps you turn obligations into practical controls
MAEZ helps Australian transport and supply-chain businesses turn Chain of Responsibility, HVNL, WHS, transport safety, and chartered risk obligations into practical training, advisory, audit, and implementation pathways.
We help you identify the gaps before an auditor or regulator does, build Safety Management System controls around how your transport business actually runs, and prove those controls with structured evidence.
Training
Chain of Responsibility training is delivered through our dedicated training platform, giving operators, managers, and executives a practical understanding of duties and controls.
Software where needed
Where software is the right next step, CoRGuard supports the evidence workflow — records, reminders, diaries, audits, maintenance, inductions, corrective actions, and evidence reporting.
If you want a practical review of the controls, evidence, training, and SMS gaps that matter most to your operation, contact MAEZ today.

Frequently asked questions
Questions people ask about this topic
Does a signed fitness-to-drive form protect my business from Chain of Responsibility prosecution?
No. A fitness-to-drive form records a driver's claim of fitness — it does not verify it. Under the HVNL, every party in the chain must take all reasonably practicable steps to ensure safety, and a signed declaration alone does not discharge that duty.
What happens if a heavy vehicle driver refuses a drug or alcohol test after a crash?
Refusing an oral fluid sample after an incident is itself an offence, and the driver will face court. The investigation may also extend to the driver's employer, the loader, and their employers for offences such as allowing an unfit person to drive a heavy vehicle.
Am I liable under Chain of Responsibility if I don't directly employ the driver?
Yes. Everyone who influences a transport task — consignors, consignees, loaders, schedulers, managers, and contractors — shares the duty to ensure the driver is fit to drive. You cannot contract out of or delegate this responsibility through a declaration form.
What is the alcohol limit for heavy vehicle drivers in Australia?
Heavy vehicle drivers must maintain a zero alcohol reading — the same standard that applies to provisional (P plate) drivers. A heavy vehicle is defined as one with a Gross Vehicle Mass of 4.5 tonnes or more.
How does MAEZ help transport businesses manage fitness-to-drive and CoR obligations?
MAEZ identifies gaps in your Chain of Responsibility and Safety Management System before a regulator does, builds practical controls around how your business actually runs, and provides structured evidence through training, advisory, audit, and CoRGuard software where needed.
