The owner shall, within thirty days after commencing to operate the vehicle or causing or permitting it to be operated within the State, apply to the director of finance for the registration thereof upon the appropriate official form stating therein the name and home address of the owner and the temporary address, if any, of the owner while within the State, the registration number of the vehicle as assigned thereto by the state or country, together with a description of the motor vehicle that may be called for in the form and other statements of facts that may be required by the director of finance.
The director of finance shall file every application received and register the vehicle therein described and shall issue to the owner a registration certificate of a distinctive form containing the date of its issue, a brief description of the vehicle, and a statement that the owner has procured registration of the vehicle.
No owner of a motor vehicle which has been duly registered for the current year in another state or country shall operate any vehicle or cause or permit to be operated upon the public highways, either before or while it is registered under this section, unless there is at all times displayed thereon the current registration number plates assigned to the vehicle by the other state or country, nor unless the certificate of registration is kept within the vehicle for which it is registered, or in the event the vehicle is a motorcycle, carry the certificate of registration in a convenient receptacle attached to the vehicle. The director of finance shall also furnish the owner with an emblem bearing a serial number with the words "VEHICLE PERMIT" and the date of expiration of the emblem to be placed on the rear bumper in plain sight of the vehicle, or when issued to a motorcycle emblem to be placed on rear fender.
