DHS, DOT, and Department of War Implement Temporary Flight Restriction for Drones Along Southern Border

The Department of Homeland Security (DHS), Department of Transportation (DOT), and Department of War (DOW) have initiated a new, coordinated effort to enhance airspace security along the southern U.S. border. A temporary flight restriction (TFR), effective immediately, prohibits unauthorized drone activity up to 400 feet above ground level and extends one nautical mile north of the U.S.-Mexico border to counter illicit cartel activity and national security threats.
