Fatigue Offences for Truck Drivers in Australia:

What You Need to Know

Managing fatigue is a serious matter for truck drivers, and the rules changed on 1 August 2026 when the amended Heavy Vehicle National Law came into force. Long hours and demanding schedules make fatigue one of the biggest safety risks on our roads, and the new law backs that up with much tougher penalties for driving while fatigued and for dishonest work diary entries. At the same time, some of the paperwork traps that used to catch honest drivers have been removed or downgraded.

At Big Rig Law, we understand the pressures that come with long distance driving. If you have been pulled over or charged with a fatigue offence, whether under the old rules or the new ones, we are here to help you through the legal process and get the best outcome we can.

What Are Fatigue Offences?

A fatigue offence happens when a driver breaches the HVNL fatigue requirements. Standard work and rest hours have not changed under the amended law, so the familiar limits on how long you can work and how much rest you must take still apply. What has changed is the framework around them. The old BFM and AFM accreditation modules are being replaced by Alternative Compliance Accreditation for Fatigue, with drivers operating on Alternative Compliance Hours (ACH) within approved outer limits. If you hold BFM or AFM accreditation you can keep operating under it until it expires. The long-standing duty not to drive while fatigued now carries a much higher maximum penalty, and it is joined by a separate new duty not to drive while unfit to drive, which covers illness, injury, medication effects and psychological distress. The key aspects of the fatigue management rules include:

Maximum driving hours: Drivers can only work a set number of hours in a day. For example, under standard hours, you can drive for up to 12 hours in a 24-hour period, with specific rest breaks required. Remember, 24-hour periods arent counted from 12.00am to 11:59pm: they commence from the end of any major rest break AND can overlap with another 24-hour period.
Rest breaks: Drivers must take regular rest breaks, and the length of these breaks depends on the hours they are operating under and how many hours they’ve been driving. For example, on standard hours, after 5 hours and 15 minutes of work, you’re required to take a minimum of a 15-minute break.
Work diary: Every driver travelling more than 100kms from base must keep an accurate log of their driving hours and rest breaks, to be presented if requested by an officer. From 1 August 2026 some entries became optional, including marking the day of the week, recording total work and rest hours at the end of a shift and ticking the Standard hours box. The duty to record your actual work and rest times accurately has not changed.

If you’re found to have breached these rules, whether by driving too long without a break or failing to record your hours correctly, you can be charged with a fatigue or work-diary offence.

Why Do Fatigue Offences Happen?

Fatigue offences are often unintentional and can happen to even the most experienced drivers. The transition to the new accreditation scheme adds another layer, because drivers moving from BFM or AFM to ACH need to record the right details in the right place. Some common reasons why drivers get caught up in fatigue offences include:

Mistakes in the work diary: Fatigue management laws are complicated, and it’s easy to make mistakes when recording hours. Even a small error in your diary can result in a fine.
Pressure to meet deadlines: Many drivers are under significant pressure to deliver goods on time, which can sometimes lead to pushing the limits of the law.
Misunderstanding the rules: The fatigue management laws differ slightly across states and territories, and it can be difficult to keep track of the exact rules when crossing borders.
Confusion over 24-hour periods: This is a common issue for truckies with a large number of prosecutions boiling down to not understanding how 24-hour periods operate. Pages 21 to 28 of the National Driver Work Diary explains how to count time and provides helpful examples.
Long hours without rest: It’s not always easy to find a suitable place to stop for a rest, particularly in remote areas. This can lead to drivers unintentionally breaching their required rest times.

At Big Rig Law, we understand these challenges. If you’ve been accused of a fatigue offence, we can help you build a strong defence, and where possible, work to reduce the penalties you’re facing.

What to Do If You’re Pulled Over for a Fatigue Offence

Being pulled over and accused of a fatigue offence can be a stressful experience, but it’s important to stay calm and follow the correct steps. Here’s a protocol to follow if you find yourself in this situation:

1. Stay Calm and Cooperate

When you’re pulled over, the best thing you can do is remain calm and polite with the enforcement officer. Show them your work diary and any other documents they request. Being cooperative helps the situation from escalating unnecessarily.

2. Check the Work Diary Carefully

If the officer flags an issue with your work diary, take the time to check it carefully. Remember that some entries that used to be mandatory are now optional, and an officer working from habit may flag something that is no longer an offence. If there is a discrepancy in your hours or rest breaks, ask the officer to explain exactly where the issue lies.

3. Avoid Admitting Fault

While it’s important to be polite and cooperative, it’s equally important not to admit fault at the roadside. Even if there’s a mistake in your work diary or rest breaks, it’s best to let the legal process play out. You can acknowledge the situation without agreeing that you’ve done something wrong.

4. Document Everything

If you believe the fatigue offence charge is unfair or there’s been a misunderstanding, start documenting the situation immediately. Take photos of your work diary, the location, and any other relevant details. This can help if you decide to dispute the fine later on.

5. Contact Big Rig Law

Penalties for Fatigue Offences

The amended law rebalanced fatigue penalties from 1 August 2026. Broadly, deliberate and dangerous conduct now attracts much higher maximums, while minor slips attract lower ones. Penalties are indexed each year, so the exact figures move, and serious breaches can also mean demerit points and prosecution rather than an infringement notice. Here is where the key penalties now stand:

Driving while fatigued: The duty to avoid driving while fatigued has jumped from a maximum penalty of $8,000 to $26,610.
Driving while unfit: A new and separate duty to avoid driving while unfit to drive also carries a maximum penalty of $26,610. Unfitness covers illness, injury, medication effects and psychological distress, not just tiredness.
False or misleading work diary entries: Roughly doubled, from about $13,310 to $26,610.
Minor fatigue breaches (solo driver, standard hours): Reduced, with the maximum penalty now $3,980 and the infringement amount $398.
Failing to record information after starting work: Reduced from a maximum of $8,000 to $5,300, with the infringement amount down from $800 to $530.

At Big Rig Law, we specialise in defending drivers against fatigue offences and can help reduce fines and penalties, particularly if the breach was unintentional or the work diary error was minor.

Can You Dispute a Fatigue Offence?

Yes, fatigue offences can be disputed, particularly where the breach was minor, the diary was misread, or there was a valid reason for the error such as no safe place to stop. With the recent rule changes there is also real scope to challenge charges based on requirements that no longer exist or have changed. Big Rig Law has extensive experience defending truck drivers against fatigue charges. We will review your case, check the enforcement process for errors and work to have your fine reduced or the matter dismissed altogether.
