Overview

The South Australian Class 3 Road Friendly Suspension Mass Exemption Notice 2022 (No. 2) was enacted to provide exemptions for certain heavy vehicles and combinations fitted with certified Road Friendly Suspension from the mass requirements outlined in the Heavy Vehicle (Mass Dimension and Loading) National Regulation (MDL Regulation). This Notice was introduced to allow these vehicles to operate at higher axle masses, thereby enhancing the efficiency and flexibility of freight operations within South Australia. The Notice was made under the Heavy Vehicle National Law (HVNL), specifically under section 117, which grants the Regulator’s power to exempt certain categories of heavy vehicles. It applies to eligible vehicles such as rigid trucks, prime movers towing semitrailers, buses, B-doubles, type 1 and type 2 Road Trains, and BA triple type 1 or type 2 road trains, but excludes vehicles with tri-axle or quad axle groups. This Notice revokes and replaces the previous South Australian Class 3 Road Friendly Suspension Mass Exemption Notice 2022 (No. 1), with the primary change being the removal of references to Higher Mass Limits while maintaining functionally identical provisions. The Notice commenced on 16 December 2022 and will expire on 9 February 2024. It outlines specific conditions for axle mass limits and areas and routes where eligible vehicles can operate, ensuring compliance with road and travel conditions as well as vehicle conditions under the HVNL. Additionally, it mandates Mass Management Accreditation for operators of eligible vehicles with tri-axle groups exceeding 20.0t and requires that axles operating at specified limits must be fitted with road-friendly suspension. This regulation aims to improve the safety and efficiency of heavy vehicle operations within South Australia by providing tailored mass exemptions for certain road-friendly suspension-equipped vehicles.

Scope and Application

The South Australian Class 3 Road Friendly Suspension Mass Exemption Notice 2022 (No.2) applies to specific heavy vehicles and combinations within South Australia that are equipped with certified Road Friendly Suspension. These include rigid trucks, prime movers towing semitrailers, buses with a single drive axle or a six-tyre tandem axle group at the rear, B-doubles, Type 1 and Type 2 Road Trains, and BA triple type 1 or type 2 road trains. Notably, the Notice excludes heavy vehicle combinations with tri-axle or quad axle groups. The Notice operates under the Heavy Vehicle National Law (HVNL) and exempts these eligible vehicles from certain mass requirements as specified in the Heavy Vehicle (Mass Dimension and Loading) National Regulation (MDL Regulation). The exemption applies to specific mass limits for single vehicles or combinations, single axles or axle groups, and mass limits related to axle spacing, but only to the extent provided under the conditional axle masses set out in the Notice. Eligible vehicles must also comply with conditions regarding axle mass limits, areas and routes of operation, mass management accreditation, and the requirement for road friendly suspension for axles operating at certain limits. The Notice commenced on 16 December 2022 and will expire on 9 February 2024.

Key Provisions

The primary sections of the South Australian Class 3 Road Friendly Suspension Mass Exemption Notice 2022 (No.2) (the Notice) establish exemptions from certain mass requirements for specific heavy vehicles fitted with certified road friendly suspension. This Notice, which commences on 16 December 2022 and expires on 9 February 2024, applies to eligible vehicles such as rigid trucks, prime movers towing semitrailers, buses with specific axle configurations, B-doubles, and certain road trains, excluding those with tri-axle or quad axle groups (sections 2, 3, 4, 7). The Notice exempts eligible vehicles from prescribed mass requirements set out in the Heavy Vehicle (Mass Dimension and Loading) National Regulation (section 8). The eligible vehicles can operate with increased mass limits, subject to specific conditions, such as additional mass limits for axles and configurations (section 9), and compliance with road conditions, travel conditions, and vehicle conditions when operating on specified networks (section 10). The Notice imposes several obligations on the parties governed by it. Operators of eligible vehicles must ensure their vehicles meet the specified configurations and comply with the conditions set out in the Notice, including obtaining Mass Management Accreditation for tri-axle groups exceeding 20.0t (section 11). Additionally, any axle operating at the exempted mass limits must be fitted with road friendly suspension (section 12). The Notice also requires eligible vehicles to adhere to the road, travel, and vehicle conditions stipulated in the Heavy Vehicle National Law when operating on the specified networks (section 10(3)). Breach of any provisions under this Notice may lead to civil or criminal consequences. However, the Notice itself does not specify any particular offences, penalties, or consequences for non-compliance. Any violations of the conditions or requirements would likely be subject to the general provisions of the Heavy Vehicle National Law and associated regulations, which could include fines and other penalties. The exact penalties would depend on the specific breach and the applicable laws at the time of the offence.
