Turn the raw legal text into a practical explanation grounded in National Transport Commission (Road Transport Legislation – Heavy Vehicle Standards Regulations) Regulations 2006.
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.
Note: The following terms defined in clause 10.6 are used in this Part:
ADR prime mover
GVM semi‑trailer
mudguard
Note: 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(a) the requirement has been superseded by, or is inconsistent with, a requirement of a third edition ADR; and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) A vehicle need not comply with an ADR if:
(a) despite non‑compliance with the ADR, approval has been given, under subsection 10A(2) or 10A(3) of the Motor Vehicle Standards Act 1989, to place identification plates on vehicles of that type; and
(b) the vehicle complies with the approval conditions (if any).
Note: Section 10A of the Motor Vehicle Standards Act 1989 deals with the attachment of identification plates to vehicles. Subsection 10A(2) deals with vehicles that do not comply with an ADR, but the non‑compliance is only in minor and inconsequential respects. Subsection 10A(3) deals with vehicles that do not comply with an ADR, and the non‑compliance is not minor and inconsequential, but the vehicle will be safe to use if specified conditions are observed.
(2) The luminous transmittance requirements in paragraph 2.16(2)(b) apply instead of the corresponding requirements in the relevant ADR.
(3) 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.
(4) A vehicle to which subclause 5.38(3) applies need not comply with any requirements of a third edition ADR that would prevent it displaying lights or reflectors mentioned in subclause 5.38(3).
(5) A vehicle to which subclause 5.38(4) applies need not comply with any requirements of a third edition ADR that would prevent it displaying the lights permitted by the subclause.
1.4 Additional equipment on vehicles
(1) 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.
(2) If a third edition ADR contains a requirement for equipment fitted to a vehicle manufactured on or after a specified date, any equipment of that kind fitted to the vehicle after manufacture of the vehicle must comply with:
(a) the requirement as in force when the vehicle was manufactured; or
(b) if the requirement is amended in the period after the manufacture of the vehicle and before the fitting of the equipment—the requirement as in force:
(i) when the vehicle was manufactured; or
(ii) when the equipment was fitted; or
(iii) at any time between manufacture and the fitting of the equipment.
1.5 Compliance with later editions of standards
A vehicle need not comply with an edition of an ADR, or an Australian Standard or a British Standard, mentioned in this Schedule if the vehicle complies with a later edition of the ADR or a later standard.
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.
