You will need to comply with this Australian Design Rule if you intend to manufacture, import, or operate any of the following vehicles:
- a prime mover built after 1987 with a GVM of more than 15 tonnes.
- a bus built after 1987 with a gross vehicle mass (GVM) of more than 14.5 tonnes
- a bus built after 1 July 1991 with a gross vehicle mass (GVM) of more than 5 tonnes, up to 14.5 tonnes
- a heavy goods vehicle built after July 1 of up to 300 horsepower
- a heavy goods vehicle built after January of over 300 horsepower.
The maximum road speed capability for heavy vehicles designed for use in a 'road train' is to be determined by the relevant State or Territory authority. The maximum road speed capability of other heavy vehicles should not exceed 100 kilometres per hour (100km/h).
This rule does not apply to:
- an emergency or police vehicle
- a bus fitted with hand grips or similar equipment for standing passengers
- a two axle prime mover that was built after 1987 but before July 1991 and is used for agriculture, horticulture or other primary production activities (excluding forestry, fishing and mining).
