restricted area
No-go zone
A restricted area is a space where access is limited or controlled, typically for reasons of security, safety, or privacy.
Military bases, government facilities, and construction sites commonly designate restricted areas where unauthorized personnel may not enter.
In basketball, the restricted area is a marked zone beneath the basket where defensive players cannot draw charging fouls.
Personnel without proper clearance are not permitted in restricted areas.
