Overview

The Heavy Vehicle National Law National Class 3 Rear Overhang Dimension Exemption Notice 2024 (No. 2) was enacted to address the specific operational needs of heavy vehicles equipped with a forklift mount attached to the rear, thereby creating an exemption from certain rear overhang dimension requirements for these vehicles. This notice was issued under the authority of the Heavy Vehicle National Law, specifically sections 117 and 23 of Schedule 1, which grant the Regulator the power to exempt certain classes of heavy vehicles from compliance with mass or dimension requirements and to amend or repeal related instruments. The notice revokes and replaces the previous National Class 3 Rear Overhang Dimension Exemption Notice 2024 (No. 1) and commences on 21 February 2024, expiring on 9 February 2029. The primary objective of this notice is to facilitate the safe operation of heavy vehicles with forklift mounts by providing specific dimensional exemptions while ensuring road safety through prescribed conditions and warnings. The notice applies to class 3 heavy vehicles, including rigid trucks, prime movers towing semi-trailers, and B-doubles, provided they meet certain dimensional and operational requirements. Eligible vehicles are exempt from rear overhang dimension requirements but must adhere to specified maximum dimensions and minimum lengths, and they must display appropriate warning signals. The notice also outlines permissible routes and areas for operation, subject to compliance with additional conditions and restrictions. This regulatory approach aims to balance operational flexibility for certain heavy vehicles with the imperative of maintaining road safety standards.

Scope and Application

The Heavy Vehicle National Law National Class 3 Rear Overhang Dimension Exemption Notice 2024 (No.2) applies to certain class 3 heavy vehicles that have a forklift mount attached to the rear, irrespective of whether a forklift is carried at any given time. This notice specifically pertains to rigid trucks, prime movers towing semi-trailers, and B-doubles. It is designed to exempt these vehicles from certain dimensional requirements, provided they meet specific conditions outlined in the notice. The notice applies across all participating jurisdictions and is effective from 21 February 2024 until 9 February 2029. It establishes exemptions from rear overhang dimension requirements, subject to dimensional limits and other conditions such as minimum vehicle length, warning signal requirements, and operational routes. Vehicles that meet these conditions are deemed eligible and benefit from the dimensional exemptions while complying with other specified conditions and restrictions, ensuring safe and compliant operation on Australian roads.

Key Provisions

The National Class 3 Rear Overhang Dimension Exemption Notice 2024 (No.2) is a regulatory notice that governs the exemption of certain heavy vehicles from specific dimension requirements, as outlined in Schedule 6 of the Heavy Vehicle (Mass Dimension and Loading) National Regulation (section 7).

The eligible vehicles include rigid trucks, prime movers towing semi-trailers, and B-doubles (section 7). The exemption applies in all participating jurisdictions and is effective from 21 February 2024 until 9 February 2029. Under this notice, eligible vehicles are exempt from the rear overhang length dimension requirements, provided they adhere to the specific conditional dimension limits specified in section 9 (section 8). These vehicles must not exceed a maximum rear overhang length of 4.0 metres (section 9). Additionally, for rigid trucks and prime movers towing semi-trailers, the minimum length of the vehicle or the last trailer must be at least 9.5 metres, excluding the forklift or forklift mount (section 10). For B-doubles, the maximum lengths are 19.0 metres in jurisdictions other than Tasmania and 21.0 metres in Tasmania (section 11).
