On 1 August 2026 the Heavy Vehicle National Law changed more than it has in over a decade. There is no grace period. The National Heavy Vehicle Regulator has been clear about that, which means you were expected to be compliant from day one, not from whenever your next audit rolls around.
If you drive a truck, run a yard, do the scheduling, or sign off on a load anywhere in the Hills District or Western Sydney, this affects you. Below is what actually changed, in plain English, and what I would be doing about it this month.
What Changed on 1 August
The Heavy Vehicle National Law Amendment Act 2025 passed the Queensland Parliament in November last year and commenced on 1 August. Because the HVNL is a national law adopted in NSW, the changes apply here automatically.
There are four areas worth knowing about.
- A new duty not to drive while unfit – The old duty was about fatigue and nothing else. The new one is about fitness to drive generally, so it takes in illness, injury, medication, mental health, drugs and alcohol. It also applies to every heavy vehicle over 4.5 tonnes, not just the fatigue regulated vehicles over 12 tonnes.
- A new accreditation framework – The National Heavy Vehicle Accreditation Scheme has been replaced. There are now two tiers, a baseline accreditation for all accredited operators and an alternative pathway for those wanting concessions.
- BFM and AFM are gone – Basic Fatigue Management and Advanced Fatigue Management have been folded into a single alternative compliance hours standard. If your operation runs on BFM or AFM concessions, you need to know how the new standard applies to you.
- Work diaries and record keeping – Record keeping requirements have been simplified and the written diaries have been updated. Electronic work diaries have been changed to match.
Mass, dimension and loading provisions were also revised. The proposed increase to the general height limit did not make it into this commencement and has been left for a later amendment, so do not plan around it.
The Unfit to Drive Duty Is the Big One
Of everything in the package, this is the change I expect to see in court first.
Fatigue was always the focus. A driver had to avoid driving a fatigue regulated vehicle while impaired by fatigue, and the whole compliance apparatus, work diaries, rest breaks, counting time, was built around that. It was a reasonably contained obligation and everybody knew where the edges were.
The new duty is much wider. It asks whether the driver is fit to drive at all. A driver on strong pain medication after a back injury may be inside every fatigue limit and still be caught. So may a driver working through the flu, or one dealing with a genuine mental health issue.
And it does not stop at the driver. Employers, prime contractors, operators and schedulers all have to make sure their business practices are not pressuring drivers to drive while unfit. If your run times only work when a driver pushes through something they should not push through, that is now your problem as well as theirs.
The other half of it is that drivers are legally backed to stop. A driver who says they are not fit to go is exercising a right, not making an excuse, and an operator who treats it as the latter is exposed.
If you are running a fleet out of Arndell Park, Eastern Creek or anywhere along the M7, this is the change to sit down with your schedulers about.
Penalties Have Moved Twice
Be careful with any figure you read online at the moment, including on other law firms’ websites.
Penalties were indexed on 1 July 2026, as they are every year. Then the amended offence provisions took effect on 1 August with their own penalty amounts built in. Around 50 penalties went up, some of them roughly doubling, and around 21 went down, mostly administrative ones.
The practical result is that almost every heavy vehicle penalty table published before August is now wrong, and the ones published before July were wrong already.
The current schedule is on the NHVR website and it is the only figure I would rely on. When a notice comes in, read the schedule alongside it, and check the risk category before you check the dollar amount. Most of the money in these matters sits in the category, not the base penalty.
Chain of Responsibility, and Why Your Paperwork Matters More Now
Chain of responsibility is not new. What has shifted is how much weight sits on being able to prove your systems actually work.
A safety management system that lives in a folder and does not match what happens in the yard has always been a weak position. It is now a much weaker one. Auditors are looking at whether the system is present, whether it is suitable, whether it is operating, and whether it is effective. A policy that ticks the first box and fails the other three is not going to help you.
What that looks like in practice:
- Scheduling records – Can you show the run was capable of being done lawfully, at the times you set, on the route you set?
- Training records – Not that training exists, but that this driver did it, on this date, and what was covered.
- Fitness for duty processes – Pre-start checks, a clear position on medication and illness reporting, and somewhere for a driver to raise a problem without it costing them work.
- Maintenance and pre-trip records – Dated, kept, and matching the vehicles you actually ran.
“We trust our drivers to make the right call” was never a compliance system. It is now a sentence that will be read back to you.
Which Version of the Law Applies?
This is the question I have been getting most, and it is a fair one.
The amended provisions do not apply retrospectively. What matters is the date of the conduct, not the date the notice landed in your letterbox. Notices are still being issued now for things that happened in June and July, and those matters fall to be dealt with under the law as it stood on the day.
When a whole regime changes at once, that gets missed. It is worth checking that the offence charged and the penalty being sought actually match the law that applied at the time, because if they do not, that is the end of it before anyone argues about the facts.
What I Would Be Doing This Month
If you are an operator:
- Audit your own safety management system before someone does it for you. Whatever gaps you find, you would rather find them than have them found.
- Work out where you sit under the new accreditation framework, particularly if you were running under BFM or AFM.
- Brief your schedulers on the unfit to drive duty. They are the ones most likely to create the exposure and least likely to have heard about it.
- Check your written and electronic work diaries are the current versions.
If you are a driver:
- Do not assume the hours you were running last month are the hours you are running now, especially under an accreditation.
- Keep filling in the diary as you go, not from memory at the end of a shift. Counting time is unforgiving and a diary written from memory becomes the evidence against you.
- If you are not fit to drive, say so. That is now expressly your right and it is a much better conversation than the one after an incident.
Frequently Asked Questions – HVNL Changes 2026
Does this apply to me if my truck is under 12 tonnes?
Some of it does. The HVNL applies to vehicles over 4.5 tonnes, and the new unfit to drive duty applies across that whole group. Work diary obligations still attach to fatigue regulated vehicles, principally those over 12 tonnes and certain buses, so a smaller vehicle can be caught by the fitness duty without being caught by the diary requirements.
Is there a transition period?
No. The NHVR has confirmed there is no grace period, so the amended law applied from 1 August. That is unusual for a change of this size and it caught a number of operators out.
I got a notice for something that happened in July. Which law applies?
The law as it stood when the conduct occurred. The amendments are not retrospective. If you have a notice that straddles the commencement date, it is worth having the offence and the penalty checked against the correct version before you pay anything.
Can my employer be charged for something I did?
Yes, and so can the scheduler, the consignor and the loader. Every party who could have exercised control or influence over the transport task can be liable for the same breach, and a party can be prosecuted whether or not anything actually went wrong.
Should I just pay the infringement?
Not before someone checks the risk category. Mass, dimension, loading and fatigue breaches are graded minor, substantial, severe or critical, and the category drives the penalty by a large multiple. Getting the category wrong at the roadside is common and it is often worth more than any argument about the facts. Paying accepts the category.
Does the NHVR only deal with these matters by prosecution?
No. There is a formal warning, improvement notice and enforceable undertaking pathway as well. An accepted undertaking commits the business to specified safety improvements and avoids a conviction. It is not available for everything and it needs a serious proposal rather than a promise to do better, but where the failure is real and you are willing to fix it properly, it is worth raising early rather than after a plea.
Getting Advice
A change this size, with no grace period, is going to produce a wave of intercepts and investigations over the next few months. If you have been stopped, issued with a notice, or contacted by the regulator asking for records, take advice before you produce anything or say anything. What happens in the first fortnight tends to shape the whole matter.
We act for drivers, owner drivers and operators across New South Wales, and we appear in the Local Courts these matters are heard in, including Blacktown, Penrith, Parramatta and Windsor. Whether you are based in Bella Vista, Rouse Hill, Arndell Park, Eastern Creek or further west, we can look at the notice, check the category, and tell you honestly whether it is worth fighting.
