Note The Australian Vehicle Standards Rules set standards that vehicles
must comply with to be driven on roads and road-related areas.
The ADRs (Australian Design Rules) are rules for designing and building
vehicles. Imported vehicles must also comply with the ADRs.
The Vehicle Standards require a vehicle that is subject to an ADR when built or
imported to continue to comply with the ADR.
The Vehicle Standards also apply certain other standards (adopted standards)
that are intended to complement the ADRs.
The ADRs do not cover:
• vehicles built before 1969
• combinations of vehicles of any age
• every safety feature for vehicles built between 1969 and 1988.
These matters are covered by the Vehicle Standards.
In most cases, if a vehicle complies with the Vehicle Standards, it is suitable for
road use.

11
Non-application of Vehicle Standards – exemption under other
11 Non-application of Vehicle Standards – exemption under other
laws
(1) A provision of the Vehicle Standards does not apply to a vehicle or
combination if the vehicle or combination is exempt from:
(a) the provision under another law of this jurisdiction; or
(b) the corresponding provision of the law of another jurisdiction.
(2) However, the vehicle or combination is exempt only if all conditions
of the exemption (if any) are being complied with.
An exemption permitting a greater dimension limit for a vehicle is subject to
conditions about the route where, and times when, the vehicle is permitted to
travel, and the escort vehicles required to accompany the vehicle. A relevant
provision of the Vehicle Standards does not apply to the vehicle only if the
conditions are complied with.
12
Non-application of Vehicle Standards – inconsistent ADR
12 Non-application of Vehicle Standards – inconsistent ADR
requirements
A provision of Parts 5 to 13 of the Vehicle Standards does not apply
to a vehicle if:
(a) the provision is inconsistent with a requirement of a second or
third edition ADR applying to the vehicle; and
(b) the vehicle complies with the requirement.
Motor Vehicles (Standards) Regulations 2003 – Australian Vehicle Standards Rules 5
13
Non-application of Vehicle Standards – approvals under other
13 Non-application of Vehicle Standards – approvals under other
laws
A provision of Parts 5 to 13 of the Vehicle Standards does not apply
to a vehicle if:
(a) the vehicle does not comply with a requirement of an ADR
applying to the vehicle; and
(b) the provision of the Vehicle Standards corresponds to the
requirement of the ADR; and
(c) despite the non-compliance:
Act 1989 (Cwlth), an approval had been given under
section 10A(2) or (3) of that Act to place identification
plates on vehicles of that type; or
(ii) an approval to place identification plates on vehicles of
that type has been given under Schedule 3, item 4(2) or
6(2) to the Road Vehicle Standards (Consequential and
Transitional Provisions) Act 2018 (Cwlth); or
(iii) the vehicle has been entered on the RAV; and
(d) for a vehicle to which paragraph (c)(i) or (ii) applies – the
vehicle complies with the approval conditions, if any.
Note 1 Section 10A(2) of the Motor Vehicle Standards Act 1989 (Cwlth)
(repealed) dealt with vehicles that did not comply with an ADR, but the non-
compliance was only in minor and inconsequential respects.
Note 2 Section 10A(3) of that Act dealt with vehicles that did not comply with
an ADR, and the non-compliance was not minor and inconsequential, but the
vehicle would be safe to use if conditions were complied with.
Note 3 Schedule 3, items 4(2) and 6(2) of the Road Vehicle Standards
(Consequential and Transitional Provisions) Act 2018 (Cwth) provide for the
Minister to decide applications for approval made under section 10A(2) and (3) of
the Motor Vehicle Standards Act 1989 (Cwlth) that were not decided before the
repeal of that Act.
Note This Part applies the second and third edition ADRs to various
vehicles.
Under the Part, a vehicle that is subject to ADRs when it is built
generally remains subject to the ADRs throughout its life. However,
a vehicle need not comply with a standard if the standard is
Motor Vehicles (Standards) Regulations 2003 – Australian Vehicle Standards Rules 6
replaced by, or inconsistent with, a later standard and the vehicle
complies with the later standard. Older vehicles may, therefore, be
fitted with any equipment allowed on newer vehicles.
Vehicles that are modified must continue to comply with the Vehicle
Standards.
The following provisions of the Vehicle Standards extend the
application of particular second or third edition ADRs to vehicles to
which the ADRs are not expressed to apply:
• rule 41(4) (electrical wiring, connections and installations)
• rule 119 (rear marking plates)
• rule 136(1) and (2) (braking system for prime mover in B-double)
• rule 137 (braking system design for motor vehicles in road
trains)
• rule 138(1) and (3) (braking system design for trailers in
B-doubles or road trains)
• rule 155(1) and (2) (speed limiting).
The following provisions of the Vehicle Standards apply to a vehicle
instead of the corresponding ADR requirement:
• rule 44(5) and (6) (window tinting)
• rules 51 and 52 (tyre speed category requirements)
• rule 115 (warning lights and signs on buses carrying children)
• rule 118(4) (display of certain lights and reflectors).
Division 1 Interpretation
14 What is an ADR
An ADR is an Australian Design Rule.
19 Compliance with second edition ADRs
(1) If a second edition ADR recommends that the ADR should apply to
the design and construction of a vehicle, the vehicle must comply
with the ADR.
Motor Vehicles (Standards) Regulations 2003 – Australian Vehicle Standards Rules 7
(2) If a second edition ADR contains a requirement for a type of
equipment fitted to a vehicle built on or after a stated time any
equipment of the same type fitted to the vehicle after it is built must
comply with:
(a) the requirement as in force when the vehicle was built; or
(b) if the requirement is amended after the vehicle is built and
before the equipment is fitted – the requirement as in force:
(i) when the vehicle was built; or
(ii) when the equipment was fitted; or
(iii) at any time between when the vehicle was built and the
equipment was fitted.
(3) However, a vehicle, or equipment fitted to a vehicle, need not
comply with a recommendation or requirement of a second edition
ADR if:
(a) the recommendation or requirement is replaced by, or is
inconsistent with, a requirement of a third edition ADR
applying to the vehicle or equipment; and
(b) the vehicle or equipment complies with the requirement of the
third edition ADR.
(4) If a second edition ADR allows a vehicle built on or after a stated
time to be fitted with equipment, a vehicle built before the time may
also be fitted with the equipment.
20
Compliance with third edition ADRs
20 Compliance with third edition ADRs
(1) If a third edition ADR applies to the design and construction of a
vehicle, the vehicle must comply with the ADR.
(2) If a third edition ADR contains a requirement for a type of
equipment fitted to a vehicle built on or after a stated time, any
equipment of the same type fitted to the vehicle after it is built must
comply with:
(a) the requirement as in force when the vehicle was built; or
(b) if the requirement is amended after the vehicle is built and
before the equipment is fitted – the requirement as in force:
(i) when the vehicle was built; or
(ii) when the equipment was fitted; or
Motor Vehicles (Standards) Regulations 2003 – Australian Vehicle Standards Rules 8
(iii) at any time between when the vehicle was built and the
equipment was fitted.
(3) However, a vehicle, or equipment fitted to a vehicle, need not
comply with a requirement of a third edition ADR if:
(a) the requirement is replaced by, or is inconsistent with, a
requirement of a later version of the ADR applying to the
vehicle or equipment; and
(b) the vehicle or equipment complies with the requirement of the
later version.
(4) If a third edition ADR allows a vehicle built on or after a stated time
to be fitted with equipment, a vehicle built before the time may also
be fitted with the equipment.
