MC Off-Road Passenger Vehicle - a passenger vehicle having up to 9 seating positions,
including that of the driver and being designed with special features for off-road operation.
MD Light Omnibus - a passenger vehicle having more than 9 seating positions, including that of
the driver and with a Gross Vehicle Mass not exceeding 5.0 tonnes.
Manufacturer - the name of the person or company who accepts responsibility for
compliance with the Australian Design Rules and to whom the ‘Compliance Plate’ approval
certificate is issued, or, for an individually constructed vehicle, the person in whose name the
vehicle is registered.
†
Maximum Loaded Test Mass (MLTM) - the mass of the Unladen vehicle together with a full
capacity of lubricating oil and coolant and at least 75% capacity of fuel plus additional mass
equivalent to 68 kg located in each unoccupied seating position.
N Category Vehicles
NA Light Goods Vehicle - a goods vehicle with a Gross Vehicle Mass not exceeding
3.5 tonnes.
NB1 Medium Goods Vehicle - a goods vehicle with a Gross Vehicle Mass between 3.5
tonnes and 4.5 tonnes.

having at least 4 wheels; or 3 wheels and a Gross Vehicle Mass exceeding 1.0 tonne.
Parking Mechanism - a component or sub-system of the drive train that locks the drive train
