Overview

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

Explain how the South Australian Class 3 Road Friendly Suspension 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.

Mass conditions

Maximum axle mass limits provided by the Notice

The maximum axle mass limits of the Notice are listed in column 5 of Table 3.

To be eligible to operate at the maximum axle mass limit, the axle group listed in column 2 must be eligible for the GML axle mass limit shown in Column 3.

**Table 3:** Increased axle and axle group mass limits
Column 1	Column 2	Column 3	Column 4	Column 5
Axles	Axle group/tyres	General Mass Limits (GML) (t)	Additional axle spacing mass (t)	Maximum axle mass limit (t)
	Single drive axles on buses - dual tyres	9.0t	1.0t	10.0t
	6-tyred tandem-axle groups	13.0t	1.0t	14.0t
	8-tyred tandem-axle group - dual tyres	16.5t	0.5t	17.0t
	Tri-axle group - dual tyres	15.0t	2.5t	22.5t
An axle group not listed in Table 3 must operate at GML applying to that axle group. For example, a combination fitted with a quad-axle group must operate at GML on that quad-axle. Other eligible axle groups in the combination may operate at the maximum axle mass limits in column 5.

Restricted axle groups

The following axle groups are restricted in the Notice:

Tri-axle drive axle groups (drive axle groups with more than two axles)
Quad-axle groups.

Note: A combination fitted with a quad-axle group may operate at GML on that quad-axle group, while other eligible axle groups in the combination operate at the maximum axle mass limits in column 5 of Table 3.

Certified Road-Friendly Suspension (RFS)

Single axles or axle groups loaded at the increased mass limit must be fitted with a certified RFS system. RFS reduces the impact of laden axles on road pavements and most bridge structures.

Any axle or axle group not loaded to mass limits greater than GML does not need to be fitted with an RFS system.

A single axle or axle group must qualify for the stated GML and be fitted with the certified RFS before increasing to the stated increased mass limit in Table 3.

For additional information refer to Vehicle Standards Bulletin (VSB) 11 - Certification of Road-friendly Suspensions.

Mass Management Accreditation

An eligible vehicle fitted with a tri-axle group (other than a drive group) operating at increased mass limits as shown in Table 3(on those axles) must be accredited under the Mass Management Module of the National Heavy Vehicle Accreditation Scheme (NHVAS),

For more information on Mass Management Accreditation, refer to the Mass Management Accreditation Guide (PDF, 3.5MB).

General Mass Limits (GML)

Any axle or axle group of the eligible vehicle or combination that is not specified in Table 3 and is not a restricted axle group must not exceed the GML for that axle group.

General mass requirements apply mass limits for the following:

those specified by the vehicle manufacturer
individual axles and axle groups
individual components (vehicles and trailers)
the combination, including as determined by axle spacing requirements

You can find a summary of mass requirements on our mass, dimensions and loading page.

Dimension conditions

An eligible vehicle includes a vehicle designed to carry vehicles or livestock up to 4.6m in height.

Exemptions - Click to expand

This notice exempts eligible vehicles from prescribed mass requirements in Schedule 1 of the MDL Regulation. The notice is written in a way to provide similar exemptions and mass authorisations applying to HML Declarations but under a class 3 notice.

The following exemptions from Schedule 1 of the MDL Regulation apply to the extent (maximum total combination and axle mass) provided by the Notice.

Section 2 - Mass limits for a single vehicle or combination

This section relates to the maximum total combined mass of a vehicle or combination.

For example, a complying steer axle vehicle that is neither a B-double nor a road train may exceed the maximum total combination limit of 43t up to a maximum of 46t, is complying with the conditions of the Notice.

Section 4 - Mass limits for a single axle or axle group

This section relates to the maximum axle mass specified in Table 3 - Increased axle and axle group mass limits.

For example, a tri-axle group eligible for 20.0t GML may operate up to a maximum of 22.5t on that axle group when complying with the conditions of the Notice.

Section 5 - Mass limits in relation to axle spacing table 2, 3 and 4

This section relates to the maximum mass limit of an axle or combination provided under

Table 2 Axle spacing mass limits general table
Table 3 Axle spacing mass limit B-double table
Table 4 Axle spacing mass limits road train table

For example, a prime mover with a twinsteer axle group towing a tri-axle semitrailer may exceed the maximum total axle mass limit of 46.5t up to a maximum of 49.5t provided the combination complies with Notice conditions. The increased total mass must only be added to an eligible axle group, this does not include a steer axle mass increase.

Other conditions and additional information

Complying with the Heavy Vehicle National Law

The operator of a heavy vehicle must ensure their vehicle complies with the Australian Design Rules and the HVNL. Using or permitting another person to use a defective heavy vehicle, or a heavy vehicle with unapproved modifications, on the road is an offence.

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

For more information, see the Compliance and Enforcement Bulletins at www.nhvr.gov.au/ce-bulletins.

Chain of Responsibility (CoR)

Under the HVNL CoR laws, everyone in the transport supply chain must take positive steps to prevent any breach of the mass, dimension and loading provisions.

For more information on your CoR obligations, see www.nhvr.gov.au/cor

Requirement to carry the Notice

Drivers do not need to carry a copy of the Notice.
