Overview

The National Heavy Vehicle Law South Australia Class 3 Truck and Dog Trailer (up to 23m long) Mass and Dimension Exemption Notice 2022 (No.1) was enacted to address the need for exemptions from specific mass and dimension requirements for certain class 3 truck and dog trailer combinations in South Australia, enabling them to access commodity routes within the state. This legislative instrument, issued under the authority of the Heavy Vehicle National Law, revokes and replaces previous exemption notices from 2017 and 2020. The exemption aims to facilitate the movement of these heavy vehicle combinations while ensuring compliance with certain conditions and specified information detailed in the South Australia Class 3 Truck and Dog (up to 23m long) Mass and Dimension Exemption Notice Operators Guide on the National Heavy Vehicle Regulator’s website. This Notice applies to heavy vehicle combinations with a single steer axle and a tandem drive axle group towing specific types of dog trailers, and it exempts them from certain mass and dimension requirements, provided they adhere to the prescribed mass and dimension limits outlined in the Notice. The policy objective of this Notice is to streamline the operation of eligible heavy vehicle combinations in South Australia by providing necessary exemptions from specific regulatory requirements, thereby enhancing the efficiency of goods transportation while maintaining safety and compliance standards. The Notice sets out clear mass and dimension limits for eligible vehicles and specifies the conditions under which these vehicles can operate, including compliance with road, travel, and vehicle conditions as stipulated in the Heavy Vehicle National Law. The exemption also allows for additional access to certain parts of the South Australia B-Double Commodity routes, subject to conditions outlined in the Operator’s Guide. This legislative measure is aimed at balancing the needs of the transport industry with the imperative to ensure road safety and infrastructure integrity.
