3 Road transport legislation — heavy vehicle standards
For section 7 of the National Transport Commission Act 2003 (the NTC Act), Schedule 1 sets out road transport legislation, in the form of Regulations, about the design and construction of heavy vehicles.
Note 1 The road transport legislation set out in Schedule 1 does not have the force of law (see paragraph 7 (2) (a) of the NTC Act).
Note 2 These Regulations must be made in accordance with the Agreement (see subparagraph 3 (b) (ii) of the NTC Act).
Note 3 These Regulations are not subject to disallowance — see the Legislative Instruments Act 2003, subsection 44 (2) (table, item 44) and the Legislative Instruments Regulations 2004, regulation 8 and Schedule 2 item 7.
Note 4 These Regulations are not subject to sunsetting — see the Legislative Instruments Act 2003, subsection 54 (2) (table, item 51) and the Legislative Instruments Regulations 2004, regulation 9 and Schedule 3 item 4.
Note 5 The text set out in Schedule 1 is that of the Road Transport Reform (Heavy Vehicle Standards) Regulations (Statutory Rules 1995 No. 55). It has been formatted in accordance with current drafting practice (including styles of provision numbering and cross-referencing). Those Regulations were approved in draft form by the Ministerial Council for Road Transport on 10 November 1993.
Note 6 The making of the Road Transport Reform (Heavy Vehicle Standards) Regulations was notified in the Commonwealth of Australia Gazette on 29 March 1995. No date was ever fixed under subregulation 2 (2) of those Regulations.

Subregulation 4 (1)
Introductory note to Heavy Vehicle Standards
The Heavy Vehicle Standards apply to all vehicles and trailers over 4.5 tonnes GVM (gross vehicle mass), regardless of when they were built, unless they have been exempted. Some of the Standards relate to combinations of vehicles such as B-doubles or road trains.
In most cases, if a vehicle meets all of the Standards, it is suitable for use on the road without special restrictions. However, some vehicles at or approaching some of the maximum dimensions may be severely restricted as to where they can travel. These restrictions are imposed by other sets of regulations under the Road Transport Reform (Vehicles and Traffic) Act 1993. For example, other sets of regulations restrict the operation of:
· rigid vehicles more than 12.5 metres long or 4.3 metres high; and
· combinations of vehicles more than 19 metres long or 4.3 metres high; and
· vehicles with a quad-axle group.
The Standards are intended to cover areas not already covered by the Australian Design Rules (ADRs), which are a set of rules for designing and building vehicles. The ADRs do not cover vehicles built before 1969, combinations of vehicles of any age, or some vehicles built for a special purpose. These are covered in Parts 2 to 9 (inclusive) of the Standards. The ADRs did not cover every safety feature for vehicles built between 1969 and 1988. The Standards are intended to fill these gaps too. If a vehicle is covered by both an ADR and a Standard, and the 2 are inconsistent, the vehicle must generally comply with the ADR.
These Standards also require a vehicle to continue to comply with the applicable ADRs.
A vehicle must continue to comply with these Regulations, even if it is modified. The National Code of Practice: Heavy Vehicle Modifications, issued by the Federal Office of Road Safety in Vehicle Standards Bulletin 6, provides advice to help decide whether a modified vehicle continues to comply with the Regulations. It is recommended that modifications be made in accordance with the Code. Modifications that are not covered by, or consistent with, the Code may also be permitted, but the owner must ensure that the vehicle continues to comply with these Regulations. Road laws provide that vehicles must not be used on a road unless they are in a safe condition.
Part 1 Application of ADRs
Note This Part sets out how the ADRs and the other requirements in these Standards are applied to various vehicles. Vehicles are required to continue to comply with the relevant ADRs throughout their life but, because the most recent standards are the appropriate ones for today’s roads, a vehicle is allowed to meet a more recent standard instead of the one that applied to it when it was built. An earlier standard need not be complied with if it is inconsistent with a later standard dealing with the same thing on the same vehicle, and the vehicle complies with the later standard. Older vehicles are allowed to be fitted with any equipment that is allowed on newer vehicles. As explained in the Introductory Note, modified vehicles must still comply with these Standards.
The following terms defined in clause 10.6 are used in this Part:
ADR prime mover
GVM semi-trailer
mudguard
The following terms defined in section 4 of the Act are used in this Part:
motor vehicle trailer
1.1 Compliance with second edition ADRs
(1) A vehicle to which a second edition ADR applies must comply with the ADR.
(2) For the purpose of subclause (1), a second edition ADR applies to a vehicle if the cover sheet of the document containing the standard includes a recommendation by the Australian Transport Advisory Council that vehicles in a category that includes the vehicle:
(a) comply, or be designed to comply, with the ADR; or
(b) be equipped with a thing that complies with the ADR; or
(c) have instruments located so as to comply with the ADR.
(3) In spite of subclause (1), a vehicle need not comply with a requirement of a second edition ADR if:
(a) the requirement has been superseded by, or is inconsistent with, a requirement of a third edition ADR; and
(b) the vehicle complies with the third edition ADR requirement.
1.2 Compliance with third edition ADRs
A vehicle to which a third edition ADR applies must comply with the ADR.
1.3 Limitations on application of the ADRs
(1) In spite of clauses 1.1 and 1.2, a vehicle that has been exempted under the Motor Vehicle Standards Act 1989 of the Commonwealth from a requirement of an ADR need not comply with the requirement.
(2) In spite of clauses 1.1 and 1.2, the luminous transmittance requirements in paragraph 2.16 (2) (b) apply instead of the corresponding requirements in the relevant ADR.
(3) In spite of clauses 1.1 and 1.2, the requirements of subclause 2.18 (5) (relating to the speed at which a tyre must be suitable for road use) apply instead of the tyre speed category requirements in the relevant ADR.
1.4 Additional equipment on vehicles
If a third edition ADR permits a vehicle to be fitted with equipment, a vehicle may be fitted with the equipment, even though the vehicle was manufactured before the date specified in the ADR for the type of vehicle.
Part 2 General safety requirements
Note To allow a vehicle to be operated safely, every aspect of the vehicle needs to be properly designed to minimise the potential for accidents or harm to other road users. This Part sets out various requirements covering the driver’s view from, and control of, a vehicle, protection of vehicle occupants and other road users, and other safety features of a more general nature.
The following terms defined in clause 10.6 are used in this Part:
ADR GVM
approved material mudguard
Australian Standard pole-type trailer
axle prime mover
axle group repeater horn
B-double road train
driver single axle
emergency vehicle
The following terms defined in section 4 of the Act are used in this Part:

(2) A component of the steering system of a motor vehicle that is essential for effective steering of the vehicle must be built to transmit energy by mechanical means only.
(3) Failure of a non-mechanical component of the steering system must not prevent effective steering of the vehicle.
2.2 Turning ability
A motor vehicle must be able to turn both left and right, within a circle not exceeding 25 metres in diameter, measured by the outer edge of the tyre track at ground level.
2.3 Ability to travel backwards and forwards
A motor vehicle must be capable of being driven both backwards and forwards by the driver when the driver is in the normal driving position.
2.4 External or internal protrusions
(1) A vehicle must not have fitted to it an object or fitting that:
(a) protrudes from the vehicle in a way that is reasonably likely to increase the risk of injury to a person; and
(b) is not technically essential to the vehicle.
(2) An object or fitting that is technically essential to a vehicle must be designed, built and fitted to the vehicle in a way that minimises the risk of bodily injury to a person making contact with the vehicle.
Note An example of an object that protrudes but is not technically essential to a vehicle is a bonnet mascot that is rigid and is not designed to spring away on impact.
A bull bar that unduly increases the risk of injury to a person would not be allowed to be fitted. However, a well-designed bull bar that minimises the greater risk of bodily injury in an accident involving contact with the bull bar would be allowed.
2.5 Driver’s view and control of vehicle
(1) A motor vehicle must be built:
(a) to allow the driver a view of traffic to its front and sides; and
(b) with its controls located;
so that the driver can drive it safely.

(b) if the vehicle is part of a B-double-spray suppression devices complying with British Standard AU200 – 1984, Spray Reducing Devices for Heavy Goods Vehicles, Parts 1 and 2, for all axle groups or single axles of the vehicle.
(2) Paragraph (1) (a) does not apply to a vehicle if:
(a) its construction or use makes it unnecessary or impracticable to provide mudguards; or
(b) the body or part of the body of the vehicle prevents stones, mud, water, ice, or snow from being thrown up by the vehicle.
Note Examples of vehicles to which paragraph (2) (a) applies are timber jinkers, most road-making plant and some agricultural implements.
(3) A mudguard must, when the wheels of the vehicle are in position for it to move straight ahead:
(a) reduce the danger of a person contacting the moving wheels; and
(b) in the case of the rear wheels:
(i) cover the overall tyre width of the wheel or wheels for which it is provided; and
(ii) be fitted so that the height above the ground of the lowest edge of the rear of the mudguard is not more than one third of the horizontal distance of that edge from the centre of the rearmost axle.
(4) In spite of subclause (3), the mudguard may be at least:
(a) 230 millimetres above the ground; or
(b) on a vehicle built to be used off a road — 300 millimetres above the ground.
(5) The external surface of a rear mudguard, except a mudflap, that can be seen from the rear of the vehicle to which it is fitted must be coloured white or silver if the vehicle:
