Under what circumstances can a drone be flown from a moving vehicle?

A drone can be flown from a moving vehicle under specific conditions, particularly when it is not being operated over a populated area. This regulation is in place primarily for safety reasons; flying a drone over populated areas increases the risk of accidents and potential harm to people or property. By limiting flights from moving vehicles to non-populated areas, the laws aim to minimize the risk to individuals on the ground while still allowing operators to conduct their activities.

The other choices do not align with the established regulations. For instance, testing the capabilities of the drone (as mentioned in one of the options) would not inherently justify flying from a moving vehicle, especially since such testing could occur without the added complications of moving traffic. Furthermore, the lack of speed restrictions or the ability to fly anytime without regard for daylight hours poses clear dangers, as visibility and control become critical factors in safe drone operation. Thus, the only acceptable condition focuses on the proximity to populated areas, ensuring safety is prioritized during flight operations.
