Heavy Vehicle (Vehicle Standards) National Regulation (NSW)

If a third edition ADR applies to the design and construction of a heavy vehicle, the vehicle must comply with the ADR.

If a third edition ADR contains a requirement for a type of equipment fitted to a heavy 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—

the requirement as in force when the vehicle was built; or

if the requirement is amended after the vehicle is built and before the equipment is fitted, the requirement as in force at any time between—

when the vehicle was built; and

when the equipment was fitted.

However, a vehicle, or equipment fitted to a vehicle, need not comply with a requirement of a third edition ADR if—

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

the vehicle or equipment complies with the requirement of the later version.

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.

This section is subject to any provision of Schedule 2 or 3 expressly providing for the application of stated requirements of a third edition ADR.
