Overview

The Heavy Vehicle National Law Multi-State Class 1 Load Carrying Vehicles Mass Exemption Notice 2016 Amendment Notice 2020 (No.1) was enacted to address discrepancies and make minor corrections to the South Australian Schedule of the Multi-State Class 1 Load Carrying Vehicles Mass Exemption Notice 2016. This amendment was necessitated to ensure consistency and accuracy in the regulatory framework governing heavy vehicle operations across multiple states. The Notice was made under the authority of section 119 and section 23 of Schedule 1 of the Heavy Vehicle National Law (HVNL), and it commenced on 3 January 2020. The primary objective of this amendment is to update the South Australian Schedule, replacing the previous version introduced in the 2019 amendment, while maintaining the core exemptions and conditions unchanged. This Notice will remain in effect until the underlying Multi-State Class 1 Load Carrying Vehicles Mass Exemption Notice 2016 expires, is cancelled, or otherwise amended.

Scope and Application

The Heavy Vehicle National Law Multi-State Class 1 Load Carrying Vehicles Mass Exemption Notice 2016 Amendment Notice 2020 (No. 1) amends the South Australia Schedule of the Multi-State Class 1 Load Carrying Vehicles Mass Exemption Notice 2016, primarily focusing on network references and minor corrections while maintaining the primary exemptions and conditions. This amendment is applicable to load carrying vehicles in South Australia that consist of a prime mover towing either a low loader with 3, 4, or 5 axles, or a tandem axle low loader dolly along with a low loader, provided the prime mover is fitted with a single steer axle and a dual-drive tandem axle group. The total mass of these eligible vehicles must not exceed 93.5 tonnes, with a permissible additional 0.5 tonnes for complying steer axle vehicles. Specific mass limits are set for the axle groups of low loaders and low loader dollies, as outlined in Tables 1 and 2, which detail the mass limits based on the axle spacing and ground contact width. Additionally, axle spacing conditions require a minimum distance of 6.0 metres between the rearmost axle of the prime mover or dolly and the foremost axle of the low loader. Vehicles are also subject to specific route limitations based on their dimensions and mass, as detailed in the amended Schedule. The amendment does not alter the fundamental structure of the exemption but ensures that the regulatory framework remains consistent with the requirements of the Heavy Vehicle National Law, as authorised under sections 119 and 23 of Schedule 1. This Notice commences on 3 January 2020 and remains in effect until the Multi-State Class 1 Load Carrying Vehicles Mass Exemption Notice 2016 expires, is cancelled, or otherwise amended.

Key Provisions

The Multi-State Class 1 Load Carrying Vehicles Mass Exemption Notice 2016 Amendment Notice 2020 (No.1) primarily replaces the South Australia Schedule, while maintaining the primary exemptions and conditions as previously established (Section 4). This amendment incorporates changes to network references and minor corrections, updating the South Australia Schedule to reflect these adjustments. The amendment is made under section 119 and section 23 of Schedule 1 of the Heavy Vehicle National Law (HVNL), and it came into effect on 3 January 2020 (Section 2 and 3). The obligations under this legislation require operators of eligible vehicles to ensure compliance with the specified mass limits, axle configurations, and route restrictions. For instance, eligible vehicles must not exceed a total mass of 93.5t, with additional allowances for certain vehicles (Section 4(1)). Furthermore, the vehicles must adhere to specific axle group mass limits, with detailed tables provided to determine allowable masses based on the axle configuration and ground contact width (Section 5). Operators must also ensure that the axle spacings and dimensions of their vehicles comply with the conditions specified, such as maintaining a minimum distance of 6.0m between certain axles (Section 6 and 7). Failure to comply with the provisions of this Notice can result in legal consequences. Although specific penalties are not outlined in the Notice, non-compliance with heavy vehicle regulations generally can result in fines and other penalties under the Heavy Vehicle National Law. Operators found to be in breach of the mass limits, axle configurations, or route conditions could face enforcement actions, including fines and potential disqualification from operating heavy vehicles. It is crucial for operators to adhere to these requirements to avoid any legal ramifications and ensure safe and compliant vehicle operations.
