hi,
Regarding accessory number plates in QLD, used to be that you just ordered the plate, about $30 and that was that
But the last time I ordered an accessory plate I got a bill shock, the price got jacked right up.
QLD Transport now make you own the actual number plates numbers on your car before they will hand over an accessory plate
so from memory it went from $30something to $80something, at least you have the choice of transferring all those plates to another car when the time comes.
technically all rear number plates need to be lit up so at night there should be a wired in light over the accessory plate. Never heard about my local coppers pulling anyone about but I could say it happens.
Bike racks are also under same rules as protruding tow tongues so even of you take the rack off and just leave the tongue and rack mount on the vehicle... if they unsafely protrude from the back of the vehicle you can get a ticket
