The registration of an aircraft as a Special Purpose Aircraft and any other provisions contained in this Part shall in no way nullify any state laws that presently prohibit the landing or takeoff of aircraft from any public highway. These restrictions shall apply to aircraft registered as Special Purpose Aircraft, except aircraft owned or operated by the United States government, the state of Illinois and political subdivisions, and aircraft being used for medical emergencies. This Subpart I is not intended to interfere with any city, village or county ordinances.
