Restricted Areas in aviation are characterized by airspace where operations may be hazardous to nonparticipating aircraft. This means that certain activities can take place within these areas that might pose a risk to other aircraft. For instance, military training exercises, experimental flight tests, or other operations that could involve the use of live munitions or unusual flight maneuvers may occur in these zones. Therefore, while the airspace is not completely off-limits, it requires caution and coordination, ensuring that nonparticipating aircraft are made aware of these potential hazards.

The other options describe different concepts. Some airspaces may completely ban flights, such as Prohibited Areas, which are not related to the characteristics of Restricted Areas. The notion of restriction does not imply a limitation to only civilian aircraft, nor does it pertain to commercial air traffic exclusively. Thus, the best depiction of Restricted Areas aligns with the potential hazard posed to nonparticipating aircraft.
