The most recent incident happened July 17 when the fast-moving North fire jumped across Interstate 15 in the Cajon Pass and burned dozens of vehicles.

Five drones were spotted above that fire, the radio station reported, adding that planes and helicopters dropping flame retardant and water were ordered away from the area to ensure the safety of the pilots.

The incidents have prompted the state Legislature to consider a bill that would make it a misdemeanor to fly drones above fire sites, the Associated Press reported.
