Iowa Admin. Code r. 761-500.10
A registrant may delete vehicles from the fleet at any time after the commencement of the registration year. The plates and validation stickers must be returned to the vehicle and motor carrier services bureau at the time of deletion. In lieu of returning the plates and validation stickers, a qualified registrant under rule 761-500.7 (326) may submit a self-certification of IRP credential destruction on or before the vehicle(s) deletion date to the vehicle and motor carrier services bureau. Operating a vehicle with credentials that were self-certified as destroyed shall result in suspension of the self-certification privilege, and the registrant shall be responsible for any additional fees that would have been due beyond the stated destruction date.
This rule is intended to implement Iowa Code sections 326.12 and 326.15.
