Across Australia, regulators continue to emphasise that safe heavy vehicle movement depends on planning decisions made well before a driver turns a key. One area drawing sharper attention is route selection. For many operators, route choice has traditionally been treated as a dispatch or customer-service decision. Under the HVNL, that view is too narrow.
A route can create foreseeable risks involving mass limits, bridge and structure restrictions, approved access conditions, school zones, steep descents, urban clearways, restricted delivery windows and unsuitable rest opportunities. If a business sets a delivery task that effectively channels a driver toward a non-compliant or unsafe route, the legal exposure does not sit with the driver alone. Consignors, schedulers, operators and executives can all be part of the Chain of Responsibility if their decisions, directions or commercial settings contribute to the breach.
This matters because route-related risk often sits in the gap between systems. Access permits may be managed in one area, customer booking times in another, and fatigue planning somewhere else again. When those controls are not joined up, drivers can be left to solve impossible combinations on the road. A route that looks efficient on a map can become non-compliant once vehicle configuration, load characteristics, curfews, local council limits and rest break requirements are considered together.
Operators should review whether route selection is a controlled process rather than an informal habit. That means keeping current route restrictions and approved access pathways in one place, linking them to vehicle classes and load types, and making sure schedulers cannot assign a task without checking the relevant conditions. It also means having a clear escalation process where a customer delivery slot is incompatible with lawful access or safe transit.
Practical controls include pre-approved route libraries, exception approval for changed routes, local-area hazard notes, bridge and dimension alerts, and post-trip reporting when a driver encounters an unworkable route condition. If subcontractors are used, the principal contractor should still be satisfied that route instructions are lawful and realistic. Simply assuming another party will manage it is weak assurance.
This is also an executive issue. Route planning affects speed pressure, fatigue exposure, maintenance stress and load security. If management reports only show on-time delivery, not route exceptions and access conflicts, leaders may miss a growing compliance problem until it appears in an incident or roadside intervention.
The strongest operators now treat route selection as evidence of due diligence under the HVNL. They can explain who approves routes, how changes are communicated, how local restrictions are verified and what happens when commercial expectations clash with legal limits. That is exactly the kind of discipline regulators expect to see.
If your route planning still depends on local knowledge, spreadsheets and workarounds, it may be time to lift control maturity. COR’s safety management platform helps operators embed route-related CoR controls, record decisions and maintain clear evidence that planning obligations are being actively managed.
