Prohibits the operation of uncrewed aircraft, including drones, over school grounds or critical infrastructure

S 4839 prohibits drones from hovering above school grounds or critical infrastructure (like power plants, water treatment facilities, or oil refineries) below 250 feet without permission. It defines "school grounds" as all school property and "critical infrastructure" as specific facilities protected by fences or warning signs. Exceptions include government operations, law enforcement, and drones passing through at 250+ feet. Violations are punishable as class B misdemeanors for first offenses and class A for repeat offenses.
