1. If an inspection report indicates a failure to comply with applicable rules, or with the detailed plans and specifications approved by the commissioner, the commissioner may, upon giving notice, order the owner of a conveyance to make the changes necessary for compliance.
 2. If the owner does not make the changes necessary for compliance as required in subsection 1 within the period specified by the commissioner, the commissioner, upon notice, may suspend or revoke the operating permit, or may refuse to issue the operating permit for the conveyance. The commissioner shall notify the owner of any action to suspend, revoke, or refuse to issue an operating permit and the reason for the action by service in the same manner as an original notice or by certified mail. An owner may appeal the commissioner’s initial decision to the safety board. The decision of the safety board shall be considered final agency action pursuant to chapter 17A.
 3. If the commissioner has reason to believe that the continued operation of a conveyance constitutes an imminent danger which could reasonably be expected to seriously injure or cause death to any person, in addition to any other remedies, the commissioner may apply to the district court in the county in which such imminently dangerous condition exists for a temporary order for the purpose of enjoining such imminently dangerous conveyance. Upon hearing, if deemed appropriate by the court, a permanent injunction may be issued to ensure that such imminently dangerous conveyance be prevented or controlled. Upon the elimination or rectification of such imminently dangerous condition, the temporary or permanent injunction shall be vacated.
