National Class 3 Rear Overhang Dimension Exemption Notice 2026 (No.1)

Overview

The National Class 3 Rear Overhang Dimension Exemption Notice 2026 (No. 1), enacted by the National Heavy Vehicle Regulator, addresses the regulatory challenges posed by the transportation of heavy vehicles equipped with forklift mounts, which extend beyond the rear of the vehicle. This notice, made under the Heavy Vehicle National Law (HVNL), specifically amends and replaces the National Class 3 Rear Overhang Dimension Exemption Notice 2024 (No. 2). It provides exemptions from certain mass and dimension requirements for eligible class 3 heavy vehicles, including rigid trucks, prime movers towing semitrailers, and B-doubles, to facilitate smoother operations and compliance with road safety standards. The policy objective is to ensure that these vehicles can operate safely within specified parameters while mitigating potential risks associated with extended rear overhangs. The notice specifies maximum dimensions and conditions for vehicle length, warning signals, and permissible operating routes to maintain safety and regulatory compliance across participating jurisdictions.

Scope and Application

The National Class 3 Rear Overhang Dimension Exemption Notice 2026 (No.1) applies to heavy vehicles classified as Class 3, specifically those with a forklift mount attached to the rear, irrespective of whether a forklift is currently being carried. This notice encompasses rigid trucks, prime movers towing semitrailers, and B-doubles, and it is effective across all participating jurisdictions. The notice is designed to exempt eligible vehicles from certain dimension requirements stipulated in the Heavy Vehicle (Mass Dimension and Loading) National Regulation, subject to the conditions outlined in the notice. These conditions include specific dimensional limits, minimum length requirements for rigid trucks and semitrailers, and maximum length restrictions for B-doubles in different jurisdictions. The notice also mandates warning signals for day and night operations and specifies areas or routes where eligible vehicles can operate, while still requiring compliance with additional conditions set by the Specified Road Manager Network Requirements. This notice revokes and replaces the National Class 3 Rear Overhang Dimension Exemption Notice 2024 (No.2) and is made under the authority provided by the Heavy Vehicle National Law.

Key Provisions

The main operative sections of the National Class 3 Rear Overhang Dimension Exemption Notice 2026 (No.1) (the "Notice") are found in sections 2 to 10. Section 2 outlines the purpose of the Notice, which is to provide an exemption from certain dimension requirements for class 3 heavy vehicles with a forklift mount attached to the rear. Section 3 states that the Notice revokes and replaces the National Class 3 Rear Overhang Dimension Exemption Notice 2024 (No.2). Section 4 identifies the authorising provisions under the Heavy Vehicle National Law (HVNL), specifically sections 117 and 23 of Schedule 1, which grant the Regulator the power to exempt a category of class 1 or 3 heavy vehicles from compliance with mass or dimension requirements and to amend or repeal an instrument, respectively. Section 5 sets the commencement and expiry dates of the Notice, effective from 23 March 2026 until 9 February 2029. Section 6 provides definitions relevant to the Notice, including "forklift mount" and "rear of the vehicle". Section 7 specifies the application of the Notice to eligible vehicles, which are class 3 heavy vehicles with a forklift mount attached to the rear, regardless of whether a forklift is carried at any given time. Section 8 provides the exemption from prescribed dimension requirements, specifically the rear overhang length, subject to the conditional dimension limits provided in section 9. Section 9 outlines the dimensional limits and conditions for eligible vehicles, including maximum length, minimum length, warning signals, and stated areas or routes. Section 10 specifies that eligible vehicles must comply with any conditions or restrictions applied to a stated area or route in the Specified Road Manager Network Requirements in the Guide. The Notice imposes several obligations and requirements on the parties or entities it governs. Firstly, eligible vehicles must comply with the dimensional limits and conditions outlined in sections 9 and 10 of the Notice. This includes ensuring that the vehicle does not exceed the maximum length specified in Table 1 of section 9, that the minimum length requirements are met, and that warning signals are displayed when operating during the day or night. Secondly, eligible vehicles must comply with any conditions or restrictions applied to a stated area or route in the Specified Road Manager Network Requirements in the Guide. This includes complying with road conditions, travel conditions, and vehicle conditions as prescribed for the area or route. Thirdly, eligible vehicles must adhere to any other relevant legislation or regulations that apply to the operation of heavy vehicles in participating jurisdictions. Breach of the provisions of the Notice may result in civil or criminal consequences, including offences and penalties. Section 119(1)(a) of the HVNL provides that an eligible vehicle operating in contravention of the Notice is guilty of an offence and liable to a penalty. The maximum penalty for an individual is 50 penalty units, and for a body corporate is 250 penalty units. In addition, an eligible vehicle that is involved in an accident or incident may be subject to investigation and enforcement action by the National Heavy Vehicle Regulator or relevant authorities in participating jurisdictions. Failure to comply with the Notice may also result in the revocation of the exemption, which would require the eligible vehicle to comply with the full dimension requirements under Schedule 6 of the Heavy Vehicle (Mass Dimension and Loading) National Regulation.
