Overview

The Queensland Class 3 Heavy Unloaded Trailer and Converter Dolly Dimension Exemption Notice 2019 (No.1) was enacted to address the need for flexibility in the regulation of heavy vehicle dimensions in Queensland. This notice, made under section 117 of the Heavy Vehicle National Law, exempts certain class 3 heavy vehicles from specific dimension requirements set out in the Heavy Vehicle (Mass, Dimension and Loading) National Regulation 2013. The exemption applies to semitrailers towed behind road train rated prime movers in Queensland, allowing these vehicles to bypass the prescribed height dimension requirement. This flexibility is intended to support the efficient operation of heavy vehicles in Queensland while maintaining safety standards. The notice, which commenced on 10 February 2019 and expires on 9 February 2024, includes conditions to ensure that the exempted vehicles are operated safely, including requirements for warning flags and lights when travelling at night.

Scope and Application

The Queensland Class 3 Heavy Unloaded Trailer and Converter Dolly Dimension Exemption Notice 2019 (No.1) applies to combinations of road trains in Queensland, specifically exempting them from certain dimensional requirements outlined in the Heavy Vehicle (Mass, Dimension and Loading) National Regulation 2013. This exemption applies to road trains with a prime mover towing at least one semitrailer and up to two unloaded trailers and two converter dollies, provided the prime mover is road train rated. The notice is applicable only within the state of Queensland, and it does not extend to other states or territories. The exemption includes specific conditions, such as the maximum allowable height of 4.6 metres, the necessity of securing the drawbar of a dolly to a loaded trailer, and the requirement of attaching a warning flag and, if travelling at night, a rear-facing delineator and a warning light. The notice specifies that Type 1 and Type 2 road trains can use designated routes and areas, details of which are available on the Transport and Main Roads website. The notice operates under the authority of the Heavy Vehicle National Law and is set to expire on 9 February 2024 unless further action is taken.

Key Provisions

The Queensland Class 3 Heavy Unloaded Trailer and Converter Dolly Dimension Exemption Notice 2019 (No. 1) outlines specific exemptions and conditions for the operation of certain heavy vehicles in Queensland. The Notice exempts class 3 heavy vehicles that are semitrailers towed behind road train rated prime movers from the prescribed height dimension requirement set out in section 8(d) of Schedule 6 of the Heavy Vehicle (Mass, Dimension and Loading) National Regulation 2013 (National Regulation) (sections 8 and 10). This exemption applies only to vehicles that meet the criteria of being part of a combination consisting of a road train rated prime mover towing at least one semitrailer, and up to two unloaded trailers, and up to two converter dollies carried on a trailer (section 9). The Notice imposes several obligations on the parties governed by it. Primarily, it mandates that the drawbar of any dolly being carried must be secured to a trailer loaded above it to minimise rear overhang (section 13). Additionally, a warning flag must be attached to the extreme end of the dolly drawbar, and if travelling at night, a rear-facing delineator must also be attached to the extreme end of the dolly drawbar, along with a warning light attached to the rear of the vehicle in the combination which has contact with the road (sections 14 and 15). The Notice also specifies the maximum height at which these vehicles may operate, which is 4.6 metres (section 12). Furthermore, it permits these vehicles to use specific routes and areas outlined in Appendices 1 of the Notice (section 16 and 17). Any breaches of the provisions outlined in this Notice could result in various consequences. While the Notice does not explicitly detail the specific offences, penalties, or consequences for breach, it is reasonable to infer that violations could lead to enforcement actions under the broader regulatory framework of the Heavy Vehicle National Law, as this Notice operates within that legal structure. Under the National Regulation, penalties for breaches of vehicle dimension requirements can include substantial fines and potential criminal charges, depending on the severity and intent of the breach. The specific penalties can vary, but they are designed to ensure compliance with national safety and regulatory standards.
