Overview
The information in this Operator’s Guide is intended to do two things:
- Explain how the South Australia Class 1 Low Loader Exemption Trial Notice 2025 (No.2) (the Notice) operates, to assist in complying with it. It is important to remember this Operator’s Guide is instructional only and it is the Notice that provides the exemption or authorisation. If there is a difference or misunderstanding between the Operator’s Guide and the Notice, the Notice has priority and must be followed. The only exceptions are the requirements or conditions set out in the ‘Network and Mapping’ section explained below.
- Provide additional information referred to in the network requirements of the Notice. This includes links to network maps and other information such as vehicle, travel and road conditions. Networks and their conditions published in the ‘Network and Mapping’ section of this Operator’s Guide are not general advice and must be treated as conditions of the Notice.
Please read the Notice and this Operator’s Guide together. To download or print this guide, use the print or PDF buttons on the top right of this page.
About the Notice
The Notice provides a Class 1 heavy vehicle combination consisting of a:
- prime mover towing a low loader dolly; or
- prime mover towing a low loader dolly and a low loader,
with exemptions from mass and dimension requirements under the Heavy Vehicle (Mass, Dimension and Loading) National Regulation (MDL).
To operate as an eligible vehicle under the Notice, a heavy vehicle combination must:
- be carrying or designed for the purpose of carrying a large indivisible item; and
- comply with the conditions of the Notice.
The Notice complements but operates separately from the National Class 1 Load Carrying Vehicle Dimension Exemption Notice 2025 (No.1)
and National Class 1 Load Carrying Vehicle Mass Exemption Notice 2025 (No.1). Operators should check these notices for access before considering applying for a permit.
For example, unladen vehicles are not eligible to operate under this Notice – but may operate under the National Class 1 Load Carrying Vehicle Dimension Exemption Notice 2025 (No.1)
Exemptions
These exemptions only apply to the extent to which conditions are granted.
Dimension exemptions
An eligible vehicle combination operating under the Notice is exempt from the following dimension requirements of Schedule 6 of MDL:
- section 3 - Length – combination or single vehicle
- section 5 – Length – rear overhang
- section 7 – Width
- section 8 – Height.
Mass exemptions
The Notice exempts eligible vehicles from the following mass requirements specified in Schedule 1 of the MDL:
- section 2 – Mass limits for a single vehicle or combination
- section 4 – Mass limits for a single axle or axle group
- section 5 – Mass limits in relating to axle spacing generally.
Additional or conditional mass limits allowed under this Notice must not exceed manufacturer mass limits as outlined in section 8 of the MDL.
The exemption only applies to combination mass and axle mass limits. If two or more mass limits are provided that impose different limits, the lower limits apply.
Note: Other mass and dimension limits in the MDL apply.

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.
Prior to commencing a journey a driver or operator of an eligible vehicle must check for any information about updates and any restrictions or limitations applying to the proposed route.
The driver or operator must, before commencing the relevant journey, identify any relevant road closures and road conditions or restrictions that may inhibit the movement of the eligible vehicle.
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.
Before operating an eligible vehicle over 4.6m high, operators should consult with SA Power Networks to ensure powerlines on the route will allow sufficient overhead clearance.
For more information, visit the Third party approvals page.
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.
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.
