The minimum spacing provided in this paragraph does not preclude the permitting of V-type, back-to-back, side-to-side, stacked, or double-faced signs at the permitted sign site. If a sign is visible to more than one highway subject to the jurisdiction of the department and within the controlled area of the highways, the sign must meet the permitting requirements of all highways and be permitted to the highway having the more stringent permitting requirements.
