What is the Heavy Vehicle Industry Master Code?
Short answer
The 2026 Master Code is a registered industry code providing authoritative guidance on heavy-vehicle hazards, risks, risk assessment and risk controls.
Plain English
The Master Code helps Chain of Responsibility parties and executives understand practical ways of managing safety risks under the HVNL. It does not replace the law or create a separate set of legal obligations.
What this means operationally
Businesses can use the Code when reviewing transport risks, procedures, safety systems, contracts, training and controls. Its contents can also become relevant if a court considers what a duty holder knew or ought to have known about a risk or control.
Who it applies to
Chain of Responsibility parties, executives and businesses whose activities influence heavy-vehicle transport safety.
Example
A consignor reviewing scheduling risks could use the Master Code to identify recognised hazards and possible controls when assessing its transport arrangements.
Exceptions and traps
The Code is guidance, not a substitute for the HVNL and not a compliance checklist guaranteeing that a duty has been satisfied.
What changed
The revised 2026 Master Code replaced the earlier 2018 version and moved from a role-based structure toward an activity-based, risk-focused structure.
Previous rule
2018 Master Code.
Legal foundation
Heavy Vehicle National Law s 632A; registered industry code framework

Frequently asked questions
Does the Master Code create new legal obligations?
No. It provides guidance and does not replace the HVNL.
Can the Master Code be used in court?
Yes. A registered code can have evidentiary relevance to what parties and executives know or ought to know about hazards, risks and controls.
Do I have to follow every recommendation in the Master Code?
The Code is not a compliance checklist. Duty holders still need to identify and manage the risks relevant to their own transport activities.
