The issue focused on regulations governing liability insurance policies for lawsuits arising out of accidents involving drones. Lawsuits typically arise when drone operators negligently operate their unmanned aerial vehicles without authorization or recklessly endanger others. Under federal law, pilots must obtain liability insurance coverage before flying drones within 500 feet of airports or aircraft carriers and 250 feet above congested areas. Some states require liability coverage even if the drone operator isn't carrying passengers or cargo. In Texas, liability coverage doesn't apply to crashes resulting from trespassing or vandalism.
