Location of signs

All tourist-oriented directional signs must be erected adjacent to the edge of the right-of-way line and on the ditch backslope. Tourist-oriented directional signs must be located more than two hundred feet [60.96 meters] in advance of the entrance road intersection and within ten miles [16.09 kilometers] of the business, service, or activity. Tourist-oriented directional signs may not be located, erected, or maintained in any place or manner as to obstruct or interfere with a free and clear view of merging or crossing traffic or otherwise create a hazard to the safety of the public.
