Overview

The South Australian Class 3 Road Friendly Suspension Mass Exemption Notice 2022 (No.1) was enacted to address the need for flexibility in mass limits for certain heavy vehicles in South Australia. This Notice was introduced to provide exemptions from certain mass requirements set out in the Heavy Vehicle (Mass Dimension and Loading) National Regulation, specifically allowing certain heavy vehicles to operate at higher axle masses when fitted with certified Road Friendly Suspension. The Notice was created under the Heavy Vehicle National Law (HVNL) and specifically under section 117, which grants the Regulator the power to exempt categories of class 1 or 3 heavy vehicles. This legislative instrument was issued by the National Heavy Vehicle Regulator and came into effect on 25 July 2022, expiring on 9 February 2024. The policy objective behind this Notice is to enhance operational efficiency and flexibility for eligible heavy vehicles in South Australia, while ensuring road safety through the requirement of Road Friendly Suspension for certain axle configurations.

Scope and Application

The South Australian Class 3 Road Friendly Suspension Mass Exemption Notice 2022 (No.1) applies to certain heavy vehicles and combinations that are eligible vehicles, specifically rigid trucks, prime movers towing semitrailers, buses with specific axle configurations, B-doubles, and type 1 and type 2 road trains, within the jurisdiction of South Australia. This Notice provides exemptions from certain mass requirements specified in Schedule 1 of the Heavy Vehicle (Mass Dimension and Loading) National Regulation, allowing these vehicles to operate at higher axle masses under specified conditions. Notably, the Notice excludes heavy vehicle combinations that have tri-axle drive groups or quad axle groups from the scope of the exemptions. The Notice also stipulates that eligible vehicles must comply with specific conditions regarding axle mass limits, areas and routes of operation, mass management accreditation for certain tri-axle groups, and the requirement for road-friendly suspension for axles operating at certain limits. The Notice revokes and replaces the South Australia Class 3 (Application of Higher Mass Limits) Mass Exemption Notice 2020 (No.1), effectively updating the regulatory framework for eligible vehicles in South Australia while maintaining functional equivalence.

Key Provisions

The South Australian Class 3 Road Friendly Suspension Mass Exemption Notice 2022 (No.1) (the "Notice") provides exemptions from certain mass requirements for specified heavy vehicles and combinations that are fitted with certified Road Friendly Suspension (section 8). The Notice applies to eligible vehicles, which include rigid trucks, prime movers towing a semitrailer, buses with certain axle configurations, B-doubles, and type 1 and type 2 Road Trains, but excludes vehicles with a tri-axle drive group or a quad axle group (section 7). These eligible vehicles may operate at higher axle masses and can operate on specific networks within South Australia, as detailed in Table 3 of the Notice (section 10). The Notice imposes several conditions on eligible vehicles. For example, it sets specific mass limits for different axle configurations, allowing additional mass up to certain limits, provided the vehicle adheres to the conditional axle masses outlined in section 9 (section 9). Furthermore, eligible vehicles must comply with road, travel, and vehicle conditions as stipulated in sections 160, 161, and 162 of the Heavy Vehicle National Law (HVNL) respectively when operating on designated networks (section 10). Operators of eligible vehicles with a tri-axle group exceeding 20.0t must hold Mass Management Accreditation (section 11). Additionally, any axle operating under the exemptions provided in Table 1 of section 9 and exceeding General Mass Limits must be fitted with road friendly suspension (section 12). Failure to comply with the provisions of this Notice can result in various consequences. While the Notice does not explicitly outline specific penalties, breaches of the HVNL, which governs the operation of heavy vehicles, can lead to offences and penalties. For instance, operating a heavy vehicle in a manner that contravenes the HVNL can result in fines and potential imprisonment. The exact penalties depend on the severity of the breach and the specific provisions of the HVNL that are contravened. Furthermore, non-compliance may also lead to the revocation of any authorisations or accreditations held by the operator, thereby affecting their ability to operate heavy vehicles within South Australia.
