(II) In addition to the taxes and fees to register the vehicle, prorated registration taxes and fees from the date the vehicle was required by law to be registered to the date the owner applied to register the vehicle.

Nothing in this paragraph (b) shall be construed to exempt the owner of an idled trailer from paying any fees imposed pursuant to this article other than the late fee before again operating the trailer on a public highway in this state or from paying any taxes imposed pursuant to this article. The owner shall provide to the department or authorized agent a sworn affidavit that states that the trailer has not been operated on the public highways during the period for which it was not registered as required and describes the nature of the business conditions that resulted in the removal of the trailer from service.
