Specified heavy vehicle. Defined in regulation 4(1) as a heavy vehicle that, immediately before the commencement day, was registered under the Vehicle and Traffic Act 1999 or a corresponding law. This concept is the gatekeeper for the exhaust outlet exemption. Only vehicles with that registration status qualify. A heavy vehicle first registered after commencement does not get the benefit, regardless of its physical configuration. The definition ties the exemption to the existing fleet, not to future vehicles.

Heavy Vehicle (Vehicle Standards). This is the national regulation made under the Heavy Vehicle National Law and applied in Tasmania by section 5 of the Heavy Vehicle National Law (Tasmania) Act 2013. Regulation 4 modifies its application by disapplying Division 16 of Part 6 of Schedule 2 to buses, and disapplying regulation 99(1) to specified heavy vehicles with front exhausts. The term is defined in regulation 4(1) and referenced in the operation of that regulation.

Heavy Vehicle (Mass, Dimension and Loading) Regulation. Defined in regulation 3 as the national regulation of that name applied in Tasmania by section 5 of the Act. It is referenced in the infringement notice schedule: three of its provisions (MDL 16(2), MDL 28 and MDL 34(2)) are prescribed as infringement notice offences. This regulation is not modified by the 2023 instrument, but is treated as part of the Tasmanian law via the Act.

Infringement notice offence. Regulation 6 provides that for the purposes of section 591 of the Heavy Vehicle National Law (Tasmania), a prescribed offence is an offence against a provision specified in column 2 of the table in Part 2 of Schedule 1. The schedule then lists about 130 separate offence provisions from three sources: the Heavy Vehicle National Law (Tasmania) itself, the Heavy Vehicle (Mass, Dimension and Loading) National Regulation (three offences), and the Heavy Vehicle (Fatigue Management) National Regulation (one offence). This converts these offences into infringement notice matters, which typically carry a fixed penalty rather than being prosecuted on indictment or summarily in court.

Aggregate axle load. Defined operationally by the weighing method in regulation 5. It is the sum of all axle loads on the vehicle. The regulation permits an authorised officer to determine it either by weighing all wheels on the vehicle on a weighbridge and then adding axle loads, or by using portable devices on outer wheels. The concept is central to mass enforcement: exceeding the aggregate axle load limit is an offence under the national law (HVNL 129(1), (2), (3)).

Horizontal plane divergence. Regulation 5(2) sets a 150 mm tolerance. If the wheels being weighed are not on the same horizontal plane (e.g., one side of a vehicle is on a slope), the reading still holds as the true load unless the divergence exceeds 150 mm. This limits the scope for a challenge based on uneven weighing site conditions.

Heavy vehicle operators and drivers in Tasmania. Any person who drives or operates a heavy vehicle on a Tasmanian road is subject to the full suite of duties under the Heavy Vehicle National Law and the national regulations, except where these regulations carve out exemptions. Drivers of buses benefit from the disapplication of Division 16 of Part 6 of Schedule 2 (vehicle standards for buses). Drivers of older tractors and other heavy vehicles with front exhausts that were registered before commencement need not comply with regulation 99(1) of the national vehicle standards regulation. That saves them the cost of modifying the exhaust system or retiring the vehicle.

Owners and operators of heavy vehicles registered before the commencement day. The definition of “specified heavy vehicle” is limited to those registered under the Vehicle and Traffic Act 1999 or a corresponding law immediately before the commencement day. This excludes any heavy vehicle first registered after that date, even if it has a front exhaust. The distinction creates a transitional economic benefit for existing fleet owners but imposes a permanent compliance cost on new entrants or fleet upgrades.

Authorised officers. Regulation 5 gives them a defined set of methods for determining loads. This reduces evidentiary challenges: the officer does not need to ensure all wheels are on a perfectly level surface (within 150 mm). It also permits the use of portable weighing devices, which are more flexible than needing to bring the vehicle to a weighbridge. However, the regulation does not grant any additional power beyond what is already in the national law; it merely specifies how those powers may be exercised in Tasmania.

Bus operators exclusively. The exemption in regulation 4(2) applies only to buses. It is not vehicle class specific beyond that: any bus operating in Tasmania is not required to comply with Division 16 of Part 6 of Schedule 2. The text does not define “bus”; that term is presumably given its ordinary meaning or as defined in the national regulation. This exemption could reduce compliance costs for public transport operators and private bus companies.

Entities subjected to infringement notices. The schedule lists a large range of offences that may be enforced by infringement notice rather than prosecution. This affects all heavy vehicle operators, drivers, consignors, packers, and anyone else who can commit an offence under HVNL. The effect is to increase the likelihood of enforcement for minor breaches: a fixed penalty is more likely to be issued than a court summons. It also reduces the burden on the court system but increases the state’s capacity to collect fines.

The Department of State Growth. The regulations are administered by that department. It is responsible for notifying the making in the Gazette (regulation 2) and for any future amendments or rescission.

Duty to comply with national vehicle standards. The national regulation applies in Tasmania. Operators must ensure their heavy vehicles meet the standards unless an exemption under regulation 4 applies. For buses, Division 16 of Part 6 of Schedule 2 does not apply. For specified heavy vehicles with front exhausts, regulation 99(1) does not apply. All other vehicle standards provisions remain in force.

Right to an exemption from specific standards. If an operator operates a bus, or a specified heavy vehicle with a front exhaust that meets the description in regulation 4(3)(a) or (4)(b), they have a right not to comply with the respective provision. This is not a waiver but a legally binding modification of the national regulation. An authorised officer cannot issue an infringement notice or prosecute for non‑compliance with those provisions.

Duty to comply with mass, dimension and loading limits. The infringement notice schedule lists many mass, dimension and loading offences: HVNL 96(1) (exceeding mass limit), 102(1) (exceeding dimension limit), 109(2) (exceeding load restraint requirement), and many others. These are enforced by infringement notice. The duty remains substantive; the method of enforcement is simplified.

Right to a prescribed method of load determination. If an authorised officer weighs a vehicle, the officer must use one of the methods in regulation 5(1). If the officer uses a method not listed, the determination may be invalid. The 150 mm tolerance also protects the driver: if the divergence is under that threshold, the reading stands, but if it exceeds it, the reading is not conclusive (the regulation says the load “is” the determined load only if divergence does not exceed 150 mm). This creates a potential defence if the vehicle was on a significantly uneven surface.

Right to contest an infringement notice. The regulations do not remove the right to elect to have the matter heard in court. An infringement notice is an alternative to prosecution; the recipient can choose not to pay and contest the alleged offence. However, if they do nothing, they risk enforcement action, additional penalties, and potential licence sanctions.

Duty to comply with fatigue management obligations. Subdivision 4 of the schedule lists numerous fatigue management offences (HVNL 250, 251, 254, 256, 258, 260, 263, and many more). These cover driving hours, record‑keeping, and rest requirements. All are infringement notice offences. This exposes drivers and operators to fixed penalties for breaches that might previously have required court proceedings.

Duty to maintain accreditation. Subdivision 5 lists offences relating to accreditation under the national law: failure to have accreditation, false statements, failure to notify changes. These are also infringement notice offences. Accreditation is voluntary in some contexts but mandatory for certain activities like operating under a fatigue management exemption.

The regulations themselves do not set penalty amounts. They delegate that to the Heavy Vehicle National Law and the national regulations, which prescribe maximum penalties for each offence. However, regulation 6 and Schedule 1 define which offences can be enforced by infringement notice instead of prosecution. This has significant practical consequences: infringement notices typically attract a fixed penalty (often lower than the maximum court penalty) but are easier and cheaper for the state to issue. The schedule covers a very broad range of offences: from standard safety breaches (HVNL 60(1) - wearing a seatbelt) through to major mass offences (HVNL 129 - exceeding mass limits) and fatigue offences (HVNL 250 - driving while fatigued). The effect is that virtually all common heavy vehicle offences in Tasmania are now infringement notice matters.

For example, HVNL 60(1) concerns the driver wearing an approved seatbelt; HVNL 79(2) relates to faulty brakes; HVNL 81-83 cover lights and reflectors; HVNL 85-86 deal with vehicle condition and maintenance; HVNL 87A is about vehicle noise; HVNL 89-90 cover safe loading and insecure loads; HVNL 92(2) relates to directing or allowing an unsafe vehicle to be driven. All these are caught. The performance‑based standards offences (HVNL 25A) - operating a vehicle not complying with a PBS approval, or operating without an accreditation - are also included. The mass/dimension/loading list is extensive, including HVNL 129 (exceeding mass limit), HVNL 130 (exceeding axle load), HVNL 131 (exceeding tyre load), HVNL 132-134 (various dimension violations), and HVNL 137 (overloading through incorrect load distribution). Fatigue management offences cover virtually the entire regulatory framework: driving hours, record keeping, false entries (HVNL 287-288, 293, 296-299, 301-303, 305-310, 312, 319, 319A, 321-324A, 341, 354-355, 373-377, 392, 395-396, 399). Accreditation offences cover failing to comply with conditions, providing false information, not displaying certificates, and failing to return documents (HVNL 466-471, 476). Enforcement offences include failing to comply with an authorised officer’s direction (HVNL 488), and various obstruction and document offences (HVNL 513-534, 567-569).

The enforcement structure is that an authorised officer may issue an infringement notice for any listed offence. If the recipient pays the penalty within the prescribed period, the matter ends. If they do not pay and do not elect to go to court, further enforcement action may follow, often including a default judgment and additional costs. The regulations do not specify the penalty amounts; those are set by the national law or the relevant court rules.

Regulation 5 also facilitates load enforcement by clarifying how loads are determined. An officer using the prescribed methods can produce evidence that is presumptively correct (subject to the 150 mm tolerance). This reduces the evidentiary burden on the prosecution and makes it harder for a driver to challenge a reading based on site conditions.

Heavy Vehicle National Law (Tasmania) Act 2013. These regulations are made under that Act. Section 5 of the Act applies the national regulations as modified by these regulations. The regulations modify the application of the Heavy Vehicle (Vehicle Standards) National Regulation and prescribe infringement notice offences for the national law and national regulations. The Act itself is the primary law in Tasmania; these regulations provide local machinery.

Heavy Vehicle (Mass, Dimension and Loading) National Regulation. Referenced in regulation 3 and Schedule 1 Division 2. The regulations do not modify its application; they only prescribe three of its offences as infringement notice matters. However, the weighing methods in regulation 5 interact with the mass limits in that regulation. The tolerance of 150 mm could affect whether a load is deemed to exceed the limit.

Heavy Vehicle (Fatigue Management) National Regulation. Only one offence (HVFM 18A(1)) is listed in Schedule 1 Division 3. This is a single national regulation provision. It appears that most fatigue management offences are located in the national law itself (Subdivision 4 of Schedule 1 lists HVNL provisions), not in the fatigue management regulation. The reason for including only HVFM 18A(1) is not explained in the text; presumably that provision relates to an obligation not covered by the primary legislation.

Vehicle and Traffic Act 1999. The definition of “specified heavy vehicle” refers to registration under that Act or a corresponding law. This means that the exhaust exemption is available only to vehicles that were registered under the Tasmanian road transport law (or an equivalent interstate law) before the regulations commenced. The interaction determines eligibility: a vehicle that was never registered, or that was registered under a different law (e.g., a defence vehicle), would not qualify.

Previous regulations. Schedule 2 rescinds the 2014 regulations and all subsequent amendments. This means the 2023 Regulations are the sole source of Tasmanian heavy vehicle regulations under the national law framework. Any transitional arrangements from the earlier instruments have been removed; the text contains no savings or transitional provisions. Operators who relied on interpretations under the repealed regulations should verify whether the provisions remain in the same form.

National heavy vehicle law framework. The national Heavy Vehicle National Law (the primary law) and the national regulations (Vehicle Standards, Mass Dimension and Loading, Fatigue Management) apply in Tasmania by virtue of the Act and these regulations. Tasmania’s modifications are limited to the bus exemption, the exhaust exemption, the weighing tolerance, and the infringement notice schedule. The rest of the national framework applies unmodified.

Infringement notice regulation under the Act. Section 591 of the Heavy Vehicle National Law (Tasmania) allows the making of regulations prescribing infringement notice offences. These regulations give effect to that power. They do not affect the substantive law, only the enforcement mechanism.

The 2023 Regulations are a consolidation that rescinds and replaces the 2014 Regulations and four amending instruments. The schedule 2 lists the following revoked instruments: Heavy Vehicle National Law (Tasmania) Regulations 2014 (No. 7 of 2014); Heavy Vehicle National Law (Tasmania) Amendment Regulations 2014 (No. 125 of 2014); Heavy Vehicle National Law (Tasmania) Amendment Regulations 2016 (No. 2 of 2016); Heavy Vehicle National Law (Tasmania) Amendment Regulations 2018 (No. 6 of 2018); Heavy Vehicle National Law (Tasmania) Amendment Regulations (No. 2) 2018 (No. 7 of 2019). This indicates that the original 2014 regulations were amended four times over four years. The 2023 instrument consolidates those amendments into a single text and likely introduces the specific exemptions for buses and front exhaust vehicles. The source text provides no further detail about the content of those earlier amendments, so it is not possible to say what changed substantively. Operators who had relied on earlier versions should review the 2023 text carefully, as some provisions may have been removed or added. The regulations were notified in the Gazette on 27 December 2023 and took effect that day (regulation 2). They are administered by the Department of State Growth. No transitional or saving provisions are included, so the old regulations cease to have effect from that date.

The source text does not refer to any litigation concerning these particular regulations or any specific provisions. No cases are cited. The regulations are relatively new (2023), so it is possible that no court has yet interpreted them. However, the underlying national provisions have been the subject of litigation in other jurisdictions, and the interpretation of the 150 mm tolerance or the extent of the bus exemption could be tested. Operators should be aware that while the regulations themselves are untested in court, the national law provisions they reference have case law that may influence how Tasmanian courts apply them. The infringement notice schedule is broad, and a challenge to the validity of an infringement notice on the basis that the offence was not properly prescribed could arise. The regulations are clearly worded and appear procedurally robust, but any litigation would turn on the specific facts. The absence of saving provisions might also be challenged if a procedural step under the old regulations is contested after repeal. No reported decisions are available from the source text.

The exhaust exemption is only for vehicles registered before commencement. A heavy vehicle built identically to a “specified heavy vehicle” but first registered after the commencement day is not exempt from regulation 99(1). This creates a two‑tier fleet. An operator buying a used interstate tractor that was not registered in Tasmania before commencement may not qualify, even if the vehicle was previously operated in another state. The definition requires registration under a “corresponding law” immediately before commencement. If the vehicle was unregistered for a period before being brought into Tasmania, it might lose the exemption. Operators should check the registration history carefully.

The bus exemption is for Division 16 of Part 6 of Schedule 2 only. It does not exempt buses from any other vehicle standard. Buses must still comply with the rest of the Heavy Vehicle (Vehicle Standards) National Regulation. The text does not describe what Division 16 covers. Anyone relying on this exemption should first confirm the content of that division in the national regulation.

The 150 mm tolerance cuts both ways. If an authorised officer weighs a vehicle on a slope where the wheels are more than 150 mm out of horizontal plane, the load determination is not conclusive (the regulation says the load is determined only if divergence does not exceed 150 mm). That provides a defence. But if the divergence is 149 mm, the reading stands even if the load was actually lower. That is a material risk for operators who are overweight due to the terrain.

The aggregate axle load method is additive. Regulation 5(3) says the aggregate axle load may be determined by adding all axle loads. That seems straightforward, but it means that if any axle load is incorrectly measured, the error is compounded. An operator may be cited for exceeding aggregate weight when a single axle weight is slightly over, but the aggregate could be within legal limits if other axles are light. The officer may still choose to use the aggregate method or the wheel‑by‑wheel method.

The infringement notice schedule is exhaustive. Only the provisions listed can be enforced by infringement notice. For any other offence, prosecution must be by summons or charge sheet. Officers may not issue an infringement notice for, say, an offence that is not listed, even if it is a minor breach. However, the list is very long, covering most common offences. An operator should still check if a particular provision is listed before assuming an infringement notice might be issued.

No transitional or savings provisions for the rescinded regulations. Operators who had pending matters under the old regulations may find that those proceedings continue under the old rules, but the regulations do not state that. If the old regulations are rescinded without savings, any rights or obligations that depended on them may be extinguished. For example, an operator who was granted an exemption under the old regulations should confirm whether it continues under the new ones. The Department of State Growth may have issued a separate transitional instrument, but it is not part of this text.

Check whether your vehicle qualifies for an exemption. If you operate a bus in Tasmania, you do not need to comply with Division 16 of Part 6 of Schedule 2 of the Heavy Vehicle (Vehicle Standards) National Regulation. If you operate a heavy vehicle that was registered under the Vehicle and Traffic Act 1999 or a corresponding law before the commencement day (27 December 2023), and it has a front‑mounted exhaust that extends to the edge of the bodywork, or a vertical front‑mounted exhaust higher than the seated driver, you do not need to comply with regulation 99(1) of that regulation. Keep registration records to prove the vehicle was registered before that date. For any other vehicle, no exemption applies.

Ensure your vehicle meets all other national vehicle standards. The exemptions are narrow. All other requirements of the Heavy Vehicle (Vehicle Standards) National Regulation apply. This includes brakes, lights, reflectors, tyres, load restraint, noise, and safety equipment. Use the schedule of infringement notice offences as a checklist of what is enforced: if a provision is listed, it is likely to be checked.

Comply with mass, dimension and loading limits. The schedule lists many offences under the Heavy Vehicle National Law and the Heavy Vehicle (Mass, Dimension and Loading) National Regulation. Have a current weigh‑bridge certificate or on‑board weighing system. Know your axle group and aggregate loads. If an authorised officer weighs your vehicle, note the surface conditions. If the wheels are more than 150 mm out of horizontal plane, you may have a defence. Photograph the weighing site if possible.

Keep accurate fatigue management records. The schedule lists dozens of fatigue offences under the national law. Use an approved work diary, electronic or paper, and make accurate entries. Ensure you are driving within work and rest hours. Do not falsify records.

Obtain and maintain any required accreditation. If you operate under a fatigue management exemption or performance‑based standards scheme, you must hold current accreditation. The schedule lists offences for failing to comply with accreditation conditions, providing false information, not displaying the accreditation, and not returning documents when required.

Treat the infringement notice list as a risk map. The 130‑odd listed offences are the ones most likely to be enforced via fixed penalty. Know them. For example, HVNL 60(1) is seatbelt wearing; HVNL 79(2) is defective brakes; HVNL 81-83 are lights; HVNL 85-86 are general vehicle condition; HVNL 89-90 are loading; HVNL 129-134 are mass and dimension; HVNL 250-399 are fatigue. The risk of receiving a penalty notice is higher for these than for unlisted offences.

If issued an infringement notice, consider electing court hearing if you have a valid defence. The notice will state the penalty and how to pay. If you pay, you concede the offence. If you believe the determination was incorrect (e.g., due to uneven weighing, or because the exemption applied), you may elect to have the matter heard in court. The regulations do not prevent that.

Stay updated on any future amendments or transitional instruments. The Department of State Growth may issue further regulations or administrative guidance. Because the 2023 Regulations rescinded the old ones, any modifications to exemptions or weighting methods will need to come through an amendment to these regulations. Monitor the Tasmanian legislation website and the Department’s website.
