Question: trucks parking on properties

What is the size limit for trucks, where they can or are allowed to have them on the properties? If they are bigger than 3 tonnes or 5 tonnes I believe they may be illegally parked on the street, is that correct?

The maximum weight for a truck to be parked in a residential street or on a residential property is 4.5 tonnes Gross Vehicle Mass (GVM) or 7.5 metres in length.  A permit may be issued for a larger truck where it is parked on a residential property, however, permits are not issued for larger trucks to park in residential streets. As such, any truck exceeding 4.5 tonnes or 7.5 metres in length that is parked on a residential street would be doing so illegally.
