Other conditions and additional information

Assessing routes

Before an eligible vehicle is driven along any route, its driver and operator must be satisfied that the route has been assessed and that the vehicle can be driven along it without:

• disrupting telecommunication, electricity, rail, gas, water or sewage services; or
• damaging a road (including a bridge), structure, rail crossing or tree.

Part of this process is assessing the Map and reading this Guide before travel to identify any restrictions or conditions that may affect travel. In some cases, approval is required from third parties or entities when a vehicle exceeds certain mass or dimension limits.

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.

Warning signs

Eligible combinations longer than 22m but not longer than 30m must display a long vehicle warning sign at the vehicle's rear (as shown in Figure 1).

Eligible combinations longer than 30m must display a road train warning sign at the front and rear of the combination (as shown in Figure 2).

Warning sign requirements are described in the NHVR's Vehicle Standards Guide (VSG-19).

Complying with the HVNL

Unless otherwise exempted by the Notice or this Operator's Guide, operators must ensure their vehicle or combination complies with the:

• Australian Design Rules (ADRs); and,
• Heavy Vehicle National Law (HVNL); and,
• Heavy Vehicle (Mass, Dimension and Loading) National Regulation (MDL); and,
• Heavy Vehicle (Vehicle Standards) National Regulation (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.
