When a notice has been provided under this subsection and all of the tickets and citations are subsequently paid, dismissed, reversed on appeal or canceled, the parking authority shall notify the department electronically in a format prescribed by the department of the disposition of the tickets and shall provide the owner or registrant with a release from the suspension.

(d) Additional suspension.--The department shall impose an additional period of registration suspension if, subsequent to the issuance of a suspension under subsection (a) but prior to the restoration of the registration, the department is notified by the parking authority that the owner or registrant has failed to respond, failed to pay or defaulted in the payment of an additional ticket or citation issued for a parking violation.

(e) Three-year limitation.--No suspension may be imposed based upon a parking violation more than three years after the commission of the violation.
