(b)(1) Any governmental entity from entering into a relocation agreement pursuant to Section 5412 or the department from allowing any lawfully erected display to be increased in height at its permitted location or to be relocated provided the height increase or relocation would not cause a reduction in federal aid highway funds as provided in Section 131 of Title 23 of the United States Code or an increase in the number of displays within the state that does not conform to this article. Any increase in height permitted under this subdivision shall not be more than that necessary to restore the visibility of the display to the main-traveled way. An advertising display relocated pursuant to this subdivision shall comply with all of the provisions of Article 6 (commencing with Section 5350).

(2) A relocated advertising display may be converted to a message center pursuant to a relocation agreement. The department shall issue a permit, without any additional consideration, for any display that is being placed pursuant to a relocation agreement with another governmental entity if the relocated display conforms with the provisions of this section.
