Last checked October 29, 2026
Missouri has no statewide light pollution statute. The lighting-related provisions in the DarkSky policy database restrict lighting, size and location of signs permitted along certain highways, plus a statute on projects subject to municipal ordinances. NCSL's state roundup does not list Missouri. Outdoor fixture rules are set by cities and counties.
