The amended HVNL commenced on 1 August 2026, introducing reforms to accreditation, Safety Management Systems, audits, work diaries, fitness to drive, and mass, dimension and loading rules. Operators should confirm their compliance frameworks reflect the new requirements.
The amended Heavy Vehicle National Law commenced on 1 August 2026, marking the most significant reform to heavy vehicle regulation in Australia in more than a decade. The changes touch nearly every part of an operator’s compliance obligations — from how accreditation works to what a Safety Management System must contain — and every business in the heavy vehicle supply chain should now be confirming that its frameworks reflect the new requirements.
A new approach to accreditation
The amended law replaces the previous NHVAS module structure with a reformed accreditation scheme built around a single, outcomes-focused framework. Accreditation is now assessed against the National Audit Standard for Heavy Vehicle Accreditation, and operators seeking or renewing accreditation must demonstrate that their systems genuinely manage safety risks — not merely that paperwork exists. Existing accredited operators are subject to transitional arrangements, but should not assume their current documentation will carry over unchanged.
Safety Management Systems take centre stage
For the first time, the law formally recognises Safety Management Systems through the Safety Management System Standard 2026. An SMS that meets the Standard provides a structured way for parties in the chain of responsibility to demonstrate they are meeting their primary duty under section 26C. Executives should note that due diligence obligations under section 26D remain personal and non-delegable — an SMS supports due diligence, it does not replace it.
Work diaries, fitness to drive, and MDL reforms
The amendments also modernise work diary requirements, clarify obligations around driver fitness to drive, and restructure the mass, dimension and loading (MDL) provisions. Several prescriptive requirements have been replaced with risk-based duties, which gives operators more flexibility but also demands that they can evidence how risks are being managed. Enforcement agencies have indicated that education will be the initial focus, but the new penalty framework is in force from day one.
What operators should do now
Operators should map their current policies, procedures and training against the amended law, prioritising accreditation documentation, SMS content, and driver management processes. Gaps identified now can be closed before regulator attention shifts from education to enforcement. ALCS can assist with gap analysis, SMS development and audit preparation aligned to the new standards.
