You may require this approval if you intend to modify a vehicle. This includes any alteration to the construction or equipment of a vehicle and installing or attaching any fitting or equipment to either the inside.
VicRoads must be notified of certain changes to vehicles, including any changes to the description of the vehicle such as change of engine, colour, LPG (liquid petroleum gas) conversion, adding or removing seats, or amending the gross vehicle mass (GVM) of a vehicle (for trucks and buses). This also applies to adding, removing or replacing seats.
Depending on the type of change, you may be required to obtain a vehicle assessment signatory scheme (VASS) certificate, and/or complete a change of vehicle description form.
Please contact VicRoads for more information on whether approval is required for your vehicle modification.
