About the Notice

The Notice provides a Class 3 heavy vehicle that is a rigid truck, a prime mover towing a semitrailer, or a B-double an exemption from the rear overhang prescribed limits of the MDL. The exemption permits the attachment of a forklift mount to the back of the heavy vehicle and facilitates freight delivery by allowing eligible vehicles to operate in excess of the MDL requirements, which limits the rear overhang to either 3.7 meters or 60% of the vehicle's wheelbase, whichever is less.

Forklifts are essential for loading and unloading but may not be available at all delivery sites. This exemption allows for the legal transport of a forklift on the back of the vehicle or trailer, a practice commonly referred to as piggyback forklift or truck-mounted forklift transport.

Exemptions

These exemptions only apply to the extent to which conditions are granted.

Dimension requirements

Eligible vehicles are exempt from the following dimension requirements of Schedule 6 of the MDL:

section 5 – Length—rear overhang.

Note: Other mass and dimension limits in the MDL apply.

Definitions

The following are terms used in the Notice or conditions of operation. Unless otherwise stated, words and expressions used in this Notice have the same meaning as defined in the HVNL.

Term	Definition
ADR	Australian Design Rules.
Class 3	A heavy is a Class 3 heavy vehicle if: it, together with its load, does not comply with a prescribed mass requirement or prescribed dimension requirement applying to it; and it is not a Class 1 Heavy vehicle.
Forklift mount	A mechanism that carries a forklift and is fixed to the rear of an eligible vehicle under the Notice so that the forklift and forklift mount extend beyond the body of the vehicle.
General access	Access to all roads in participating jurisdictions, except as restricted by the 'Specified road manager network requirements' in the Guide.
HVNL	Heavy Vehicle National Law.
MDL	Heavy Vehicle (Mass, Dimension and Loading) National Regulation.
Rear of the vehicle	For a rigid truck: the rear of the truck. For a combination consisting of a prime mover towing a semitrailer or a B-double: the rear of the last trailer in the combination.
Rear overhang	For the purposes of this Notice and Guide the rear overhang of the vehicle is the distance between the rear of the vehicle including forklift and/or forklift mount and the rear overhang line of the vehicle.
Rear overhang line	For a vehicle with an axle group at the rear comprising only one axle, a (vertical) line running along the centre-line of the axle. For a vehicle with an axle group at the rear comprising two axles, one of which is fitted with twice the number of tyres as the other, the rear overhang line is a line running parallel to the axles that is— closer to the axle carrying the greater number of tyres than it is to the other axle; and located at one-third of the distance between the two axles. For a vehicle with an axle group at the rear that is not an axle group mentioned in (1) or (2), the rear overhang line is a line running parallel to the axles down the centre of the axle group. For the purposes of applying subsection (1), (2) or (3) to a vehicle, if an axle group includes at least one steerable axle, that axle is to be disregarded unless— the group comprises only one axle and that axle is a steerable axle; or all the axles in the group are steerable axles
VS Regulation	Heavy Vehicle (Vehicle Standards) National Regulation.

Forklift mounts and forklift special conditions

Number plates

Operators of heavy vehicles with forklifts attached to the rear of the vehicle or trailer in a combination need to be aware of State and Territory laws about the visibility and positioning of number plates on their vehicles.

If the forklift obstructs the view of your vehicle’s number plate

If you have an accessory number plate and the laws of your jurisdiction allow you to display one, you must:

display the accessory number plate to the rear of the forklift. The plate must be fitted according to the laws of your jurisdiction. If the forklift has its own number plate, it should be covered to avoid confusion with the accessory number plate.

If you do not have an accessory number plate or the laws of your jurisdiction do not allow you to display one, you must:

relocate the number plate of the truck or trailer to the rear of the forklift. If the forklift has its own number plate, it should be covered to avoid confusion with the truck or trailer number plate. The plate must be fitted according to the laws of your jurisdiction.

Note: In some jurisdictions, an accessory number plate is also known as an auxiliary number plate. Please contact your State or Territory registration authority to find out what type of registration plate must be affixed to the back of the forklift when carrying the forklift on the forklift mount.”

For specific requirements about number plate rules in the participating state and territory, please visit:

External projections

Operators are required to comply with Australian Design Rule 92/00 (External Projections). Australian Design Rule 92/00 mandates that vehicles must not be equipped with any exterior object or fitting which, because it is pointed or has a sharp edge, is likely to increase the risk of bodily injury to any person. Accordingly, operators are reminded to ensure that the mounting of the forklift does not create sharp edges or dangerous protrusions in breach of Australian Design Rule 92/00.

Rear lighting and markers

The mounting of the forklift should not obstruct the visibility of any mandatory lighting, reflectors or marker plates. Where this occurs:

repeater lights and reflectors must be installed in compliance with Part 6, Schedule 2 of the Heavy Vehicle (Vehicle Standards) National Regulation; and
rear marker plates installed according to Vehicle Standards Bulletin 12.

Warning flag and light requirements

Operating during the day – warning flag

When operating during the day an eligible vehicle must have a brightly coloured red, red and yellow or yellow flag at least 300mm by 300mm fixed to the extreme back of the load.

Operating during the night – warning light

When operating during the night an eligible vehicle must have a light showing a clear red light to the back, visible at a distance of at least 200m, is fixed to the extreme back of the load.

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.

Third party approvals

A third party is an entity with which consultation is required by either State or Commonwealth law, as a condition of operation or access.

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 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).

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

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.

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.
