Oregon Revised Statutes Oregon Vehicle Code § 826.027

(1) The registrant of a vehicle which is proportionally registered under ORS 826.009 or 826.011 shall be permitted to transfer the registration plates from the vehicle to a like vehicle to be similarly used if the vehicle is destroyed or permanently withdrawn from service within this state. To make a transfer of registration under this section, the registrant of the vehicle shall pay the Department of Transportation a registration transfer fee established under ORS 826.023, file a written statement indicating the withdrawal or destruction with the department and surrender the registration card for the vehicle. The department shall issue a registration card without payment of further fee. If the weight on the certificate of weight of the vehicle receiving the transferred registration exceeds that of the vehicle destroyed or withdrawn, the registrant must pay registration fees on the increased weight.

(2) If a vehicle is permanently withdrawn from a fleet that is proportionally registered under ORS 826.009 or 826.011 because it has been destroyed, sold or otherwise completely removed from the service of the registrant, the department shall provide credit for the unused portion of the fees paid according to terms of interstate agreements or in a manner defined by rule. In no event shall any such amount be subject to refund.
