Frequently Asked Questions
The National Heavy Vehicle Regulator (NHVR) is Australia’s regulator for heavy vehicles.
Established in 2013 as a statutory authority it administers one set of laws – the ‘Heavy Vehicle National Law (HVNL) which apply in all Australian states and territories except the Northern Territory and Western Australia.
Changes to the Heavy Vehicle Nation Law and Regulations commenced on 1 August 2026 and relate to the new act.
What is a safety management system?
A Safety Management System (SMS) for an operator of a heavy vehicle is the operator’s group of policies, systems, and procedures relating to the safety of its transport activities and the driving of heavy vehicles. The SMS must identify public risks associated with those activities and driving, assess the identified public risks, and specify the controls to manage and mitigate the identified public risks. For heavy vehicle accreditation, the SMS must comply with the SMS Standard, by addressing the requirements of the SMS Standard.
Is an SMS Mandatory?
It depends. Under the Heavy Vehicle National Law (HVNL) it’s not mandatory to have an SMS however, from July 2026, an operator seeking heavy vehicle accreditation must establish and implement an SMS that complies with the SMS Standard. However, implementing an SMS helps to demonstrate how your business is managing risk and ensuring the safety of its transport activities and that you are exercising appropriate due diligence to ensure your business complies with the safety duty.
Why Should I Have an SMS?
Outside of being mandatory for heavy vehicle accreditation, an effective SMS helps reduce incidents and injuries by identifying and controlling risks before they cause harm. It improves compliance and demonstrates due diligence, supports safer and more consistent operations, and helps identify new and emerging risks as the business changes. By involving workers and learning from incidents and near misses, an SMS strengthens safety culture, reduces costs from breakdowns and crashes, and supports continual improvement in everyday operations.
Other key benefits of implementing an SMS include:
- Assisting you to meet your safety responsibilities under the HVNL
- Providing you with a means to manage risk and enhance safe practices
- Assisting your business to allocate limited resources to the most critical areas that have an impact on safety
- Helping your business become a preferred supplier to customers
- Providing a framework to make informed safety decisions and increase efficiencies
- Reducing costs by proactively identifying risks before they result in repair costs, downtime, insurance claims, incidents, major accidents, and unreliable service delivery.
Do Small Businesses Need an SMS?
Yes. The size and complexity of the SMS should match the size and risk profile of the business, but every operation needs a systematic approach to safety.
Who is Responsible for the SMS?
Everyone has a role, but leadership is critical. Any person, by whatever name called (manager, director tc.), who exercises control or influence over the management or direction of a transport activity is responsible for ensuring the system is implemented and working in practice.
Do Drivers and Workers Need to be Involved?
Yes. Drivers and workers are closest to the day to day risks, so they play a critical role in identifying hazards, reporting issues, and suggesting practical controls. Their involvement helps ensure procedures reflect real
working conditions and are actually followed. An SMS that is designed or managed without worker input will quickly become ineffective, because it won’t match how work is really done
