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.
