Other conditions and additional information

Third party approvals

Gazette notices, permits and some jurisdictional laws may require third parties and other entities to provide permission for a vehicle to travel if it exceeds certain mass or dimension limits.

Operators must secure all approvals from third parties such as electricity/utility companies, rail authorities and other third parties as part of their heavy vehicle operations.

For more information, visit the Third party approvals page.

Complying with the HVNL

Unless otherwise exempted by the Notice or this Operator's Guide, operators must ensure their vehicle or combination complies with ADRs, HVNL, MDL and VS Regulation.

Using or permitting another person to use a defective heavy vehicle or a heavy vehicle with unapproved modifications on a road may be an offence.

Failure to comply may result in the driver and/or operator being liable for an offence. Penalties can include infringement notices or prosecution.

Chain of Responsibility (CoR)

Under the HVNL, every party in the Chain of Responsibility (CoR) has a positive duty to ensure the safety of their activities in relation to a heavy vehicle. This duty, known as the “primary duty”, applies to the scheduling, loading and consigning of a vehicle, as well as to its operation on a road.

Safety is broader than the safety of drivers and other road users. It also includes protection of road infrastructure, preventing damage to other vehicles or property, and minimising environmental harm. Substantial penalties may be imposed upon parties who breach this obligation and upon their executives.

For more information on your CoR obligations visit Chain of Responsibility on the NHVR website.

Our Regulatory Advice offers guidance, tips and tools for managing a range of heavy vehicle safety risks.

Loading requirements

To meet the loading requirements, the heavy vehicle must be loaded:

• in a way that load placement does not make the heavy vehicle unsafe or unstable
• in a way that the load is not likely to fall or be dislodged from the vehicle
• using an appropriate system to restrain the load.

Visit the NHVR loading page for more information on load requirements.
