(3) No sign may be permitted to exceed 12 square feet in area, and nothing on such sign may be permitted to be legible from any place on the main-traveled way or a turning roadway. (4) Not more than one sign concerning a single activity or place may be permitted within any one informational site.

(8) No lighting may be permitted to be used in any way in connection with any panel unless it is so effectively shielded as to prevent beams or rays of light from being directed at any portion of the main-traveled way of the Interstate System, or is of such low intensity or brilliance as not to cause glare or to impair the vision of the driver of any motor vehicle, or to otherwise interfere with any driver's operation of a motor vehicle.
