When a vehicle changes ownership it is required that the vehicle be taken for a roadworthy test. The new owner is allowed to use a vehicle for a period of 21 days on the previous owner's registration before the vehicle has to be registered in the new owner's name. If the roadworthy result cannot be obtained within this period, the owner may register the vehicle without being roadworthy, however a licence disc will not be issued and the vehicle may not be used on a public road. A temporary permit must be obtained from the registering authority to drive the vehicle to the testing station or repair shop. The permit is valid for three days.
