National Class 3 Road Train Prime Mover Mass and Dimension Exemption Notice 2022 Operator's Guide

The National Class 3 Road Train Prime Mover Mass and Dimension Exemption Notice 2022 (No.1) has been developed to provide road train prime movers with mass and dimension exemptions when operating within eligible combinations in the Notice. The Notice provides length exemption to eligible combinations under the Notice. It also provides flexibility for operators of road train prime movers to continue their travel when decoupling from a road train combination and to access networks when not operating as a road train.

The Notice provides 2 key access improvements for road train prime movers and eligible combinations:

Steer mass limits - Access for a road train prime mover to operate with a road train steer mass limit when operating in specific combinations
Longer combinations - Longer total combination lengths, including the 20m prime mover and semitrailer, 27m B-double, and 26m prime mover semitrailer and unladen converter dolly. The Notice's length exemption must be due to the road train prime mover length and is subject to conditions of operation and approved network conditions.

Note: The increase in combination lengths described in the Notice is to accommodate the additional length of road train prime movers. The Notice does not provide any increase to trailer dimension limits. The road train steer mass limit does not apply to a twin steer vehicle. Twin steer can operate under the Notice except in South Australia; however, it must comply with prescriptive axle mass limits for twinsteers under the HVNL in all other states.

Overview

The information in this Operator’s Guide is intended to do two things:

Explain how the National Class 3 Road Train Prime Mover Dimension and Mass Exemption 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 alternative combinations for operators of road train prime movers while still operating at road train steer mass limits. It was developed in consultation with industry groups, state road agencies and local government.

The Notice will provide operators greater flexibility in managing their fleets by:

Avoiding operators' need to use a separate, smaller prime mover to haul trailers after decoupling a road train combination – i.e. one prime mover can be used for the entire trip instead of two.
Allowing the use of bonneted prime movers;
Increasing the use of standardised trailer sets instead of shorter trailers to accommodate the length of the prime mover;
Facilitating a more productive decoupling process;
Future-proofing investment in prime movers with larger sleeping cabs to improve driver comfort and better manage fatigue.

Exemptions

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

Mass requirements

An eligible vehicle operating under the Notice is exempt from the following mass requirements of Schedule 1 of the Heavy Vehicle (Mass, Dimension and Loading) National Regulation MDL:

section 2(1)(a)(iv) and (vi) - mass limits for single vehicles
section 4, in conjunction with Table 1 of Part 2 - steer axles
section 5(2), in conjunction with Table 3 of Part 2 - axle spacing for B-Doubles

The exemption in this section only applies to the extent of the conditional mass set out in sections 10, 11 and 15, and when other relevant conditions in the Notice are met.

Dimension requirements

An eligible vehicle operating under the Notice is exempt from the following dimension requirements of Schedule 6 of the MDL:

section 3(1) – length
section 8(1)(d) – height

The exemption for height only applies to an eligible vehicle that includes a component designed and built to carry vehicles or livestock.

The exemption in this section only applies to the extent of the conditional dimensions set out in section 13, 14 and 15, and when other relevant conditions in the Notice are met.

Note: For more information on prescribed dimensions, see National heavy vehicle general dimension requirements.

Note: For more information about 4.6m high vehicles, see Operating a 4.6m high heavy vehicle as a specified semitrailer and under other notices (PDF, 321KB).

Trailer length limits

The Notice does not provide an exemption for trailer length. All trailers must comply with the same prescribed trailer dimension limits that apply to the compliant combinations (e.g. the semitrailer length limits in the MDL Regulation shown in Figure 2).

Semi-trailer measurement

Figure 2 - Diagram of a semitrailer measurement

Note: A semitrailer that exceeds the above trailer length limits is not eligible to operate under this Notice (e.g. a refrigerated semitrailer with a distance of over 12.3m when measured from the front articulation point to the semitrailer's rear).

Maximum length of a B-double under this Notice

A B-double may be up to 27m long if:

the distance from the front articulation point of the most forward semitrailer to the rear of the B-double is not more than 20.6m (see Figure 3)
the prime mover is fitted with a front underrun protective device complying with Regulation No. 93 made under the UNECE Agreement or ADR 84 – Front Underrun Impact Protection

the prime mover was manufactured after 31 December 2005 and is fitted with a cab complying with Regulation No. 29 made under the UNECE Agreement
the prime mover does not have an area carrying, or built to carry, goods, other than for a deck permitted under subsection (3A) of the MDL Regulation:
- "(3A) A prime mover in a B-double carrying, or designed to carry, vehicles may have a deck fitted over the top of the prime mover that is carrying, or built to carry, a vehicle".

Note: This is the same requirement for 26m B-doubles under the MDL Regulation (see Figure 4 below).

Dimension requirements 27m B Double

Figure 3 - Dimension requirements for a 27m B-double

Dimension requirements 26m B Double

Figure 4 - Dimension requirements for a 26m B-double

Tri-tri B-doubles

A tri-tri B-double is a B-double with tri-axle groups on both trailers. Tri-tri B-doubles must conform to the X-Y rule in the MDL Regulation.

In Queensland, a tri-tri B-double combination used on the B-double network must comply with B-doubles' axle configuration in the MDL Regulation (Schedule 6 Part 2 section 10) and have a minimum X and Y value. See Queensland specific conditions for more details.

If you are using a standard B-double trailer set in a participating state or territory other than Queensland, the X-Y measurements under this Notice are the same and will not change with a road train prime mover.

The X-Y Rule means if distance X is greater than distance Y, the difference between these distances must not be more than 1m. If distance Y is greater than distance X, the difference between these distances must not be more than 1.3m (MDL Regulation Schedule 6 Part 2 section 10) (see Figure 5).

National mass requirements - Click to expand

The following mass conditions apply nationally to an eligible vehicle or combination, unless a specific state condition provides a more restrictive condition. Please note the state-specific conditions on this page.

What are road train steer mass limits?

Road train steer axle mass limits are those that prime movers can operate at when forming part of a road train (see Table 5).

This Notice allows road train prime movers to operate at road train steer mass limits when used in any smaller (non-road train) eligible combinations under the Notice.

Table 5 - Steer mass limits of a road train prime mover

Steer axle	Mass Limit
With tyres of section width at less than 295mm, unless a complying steer vehicle	6.0t
With tyres of section width at least 295mm	6.5t
With tyres of section width at least 375mm	7.1t

Notice specific mass requirements

Under the Notice, an eligible road train prime mover can operate at the prescribed road train steer mass limits when decoupled from a road train configuration. All other prescriptive axle mass limits apply. The road train steer mass limits are shown in Table 5.

The Notice provides access for eligible combinations at the following mass limits:

General Mass Limits (GML)
1. One-tonne mass exception
Concessional Mass Limits (CML) and
Higher Mass Limits (HML), excluding Victoria

Volumetric loading is not permitted under this Notice. Mass limits for livestock carriers are restricted to prescriptive mass limits (GML, CML or HML) if operating under this Notice.

A prime mover that is eligible for road train steer mass limits shown in Table 5, applies the additional mass as an increase to the total combination mass limit.

For example, a prime mover and triaxle semitrailer combination under GML is eligible for 42.5t. Under the Notice, the same combination using a road train prime mover has an increased GML total combination up to 43.6t. The increase in mass must be due to the steer axle mass of a maximum of 7.1t and is subject to Notice conditions.

Note: In some cases, this is an increase of 1.1t, or 0.6t for a complying steer. The road train steer mass limit does not apply to a twin steer vehicle. Twin steer can operate under the Notice (other than South Australia); however, it must comply with prescriptive axle group and total mass limits for twinsteer combinations under the HVNL.

1. General Mass Limits

GML applies to all heavy vehicles and is the stated allowable mass for a heavy vehicle axle group, unless the vehicle is operating under an accreditation or an exemption under HVNL.

General mass requirements include mass limits for the following:

those specified by the vehicle manufacturer
individual axles and axle groups (see Table 6)
individual components (vehicles and trailers)
the combination, including as determined by axle spacing requirements (including tri-tri B-double axle spacing rules).

Table 6 - Mass limits of the Notice

Axle group/tyres	Axle/vehicle requirements	Tyre section width	Mass limit (t) - GML	Mass limit (t) - CML	Mass limit (t) - HML
Steer axle	Default limit	n/a	6.0	6.0	6.0
	Complying steer axle	Suitability rated	6.5	6.5	6.5
	Road train steer axle	295–375 mm	6.5	6.5	6.5
	Road train steer axle	At least 375 mm	7.1	7.1	7.1

Single axle	Single tyres	Less than 375mm	6.0	6.0	6.0
	Single tyres	375–450mm	6.7		6.7
	Single tyres	At least 450mm	7.0	7.0	7.0

	Single tyres on one axle and dual tyres on the other axle	n/a	13.0	13.5	14.0
	Dual tyres on all axles	n/a	16.5	17.0	17.0

Tri-axle group	Single tyres on all axles	Single tyres less than 375mm	15.0	15.5	15.0
	Combination of single and dual tyres	Single tyres less than 375mm	15.0	15.5	15.0
	Single tyres on all axles	At least 375 mm	20.0	21.0	22.5
	Combination of single and dual tyres	Single tyres at least 375 mm	20.0	21.0	22.5
	Dual tyres on all axles	n/a	20.0	21.0	22.5

Quad-axle	Single tyres on all axles	Less than 375mm	15.0	15.0	15.0
	Single tyres on all axles	At least 375mm	20.0	20.0	20.0
	Dual tyres on all axles	n/a	20.0	20.0	20.0

1a. One-tonne mass exception

Eligible combinations with a tri-axle group operating under this notice at GML can apply the one-tonne tri-axle mass exception (1TMTA).

1TMTA allows increased mass on tri-axle groups so that they may be loaded up to 1t above the standard tri-axle group 20t GML. Any additional mass loaded onto each tri-axle group is offset onto another non-steer axle or axle groups.

The 1TMTA does not permit any increase to a vehicle’s maximum (total) mass but gives more flexibility in how mass may be distributed across axle groups.

For more information, see 1-Tonne Tri-axle Mass Transfer Allowance.

2. Concessional Mass Limits

CML allows operators enrolled in the Mass Management Module of the National Heavy Vehicle Accreditation Scheme (NHVAS) to use mass limits above the national GML. When operating at CML under the Notice, NHVAS accredited can use the Notice's steer mass limit and the mass concession applied under CML.

The steer mass limit provided by the Notice is considered to be a part of a combination's total Gross Combination Mass (GCM) when operating at GML.

This means that, when operating at CML, the combination can apply:

the steer axle mass increase (up to 7.1t) as per the Notice; and
the increased mass limit applicable when operating under CML.

The following examples demonstrate the maximum axle and total mass limits for the combination when operating at GML and CML. Note: The 7.1t steer mass limit and converter dolly in the examples are not affected by the increase of CML.

The steer mass limits under the Notice do not apply where the concessional mass limit is provided under a separate Class 3 notice or permit (e.g. the Queensland Class 3 Heavy Vehicle Additional Concessional Mass Limits Exemption Notice 2024 (No.1)). Operators must comply with the conditions of the applicable notice or permit, including the steer mass limits.

For more information about the NHVAS, visit Concessional Mass Limits.

3. Higher Mass Limits

This Notice operates in conjunction with the HML Authorities Notice listed in Table 7.

This Notice does not provide HML access in Victoria. Access may be considered by permit.

The steer mass limit provided by the Notice is considered to be a part of a combination's total GML when operating at GML.

This means that, when operating at HML, the combination can apply:

The steer axle mass increased (7.1t) as per the Notice; and
The increased mass limit applicable when operating under HML.

The following examples demonstrate the maximum axle and total mass limits for the combination when operating at GML and HML. Note: The 7.1t steer mass limit and converter dolly in the examples are not affected by the increase of HML

Queensland - special conditions - Click to expand

In Queensland, the following conditions apply.

An eligible vehicle operating under this notice in Queensland, must take the most direct route between:

the place at which the vehicle decouples or reconfigures the prime mover and trailers that compose the combination in a such a way that it becomes an eligible vehicle; and
the place where the eligible vehicle’s journey begins or ends.

A minimum of 5m wheelbase is required for a prime mover regardless of the combination when operating with road train steer mass limits,

Example of CML application for prime mover

Figure 15 - Example of QLD prime move wheelbase

In addition to the wheelbase requirement, an eligible B-double combination operating with road train steer mass limits on the approved B-double network must comply with the following.

Tri-tri B-double combinations must comply with (A) and have a minimum X and Y values in table 9.
Axle spacing mass limits – the eligible vehicle must comply with the masses in Table 3 of Part 2 of Schedule 1 of the MDL regulation, including mass limits in the extended table in Appendix 1.
