Restricted Areas

There are many restricted areas throughout the Grand Theft Auto series, which are generally off-limits to the public, and the protagonist will gain an instant Wanted Level if they trespass within these areas. Some areas are unlockable, and thus the player will not earn a wanted level for entering these areas after a certain point in the game, but others have permanent restrictions.

Trivia

• If the player flies over Fort Zancudo, Bolingbroke Penitentiary or Los Santos International Airport, a radio message will warn the player to leave the area immediately or else their aircraft will be shot down. However, only Fort Zancudo has the capacity to shoot an aircraft down.
• In GTA Online, the Lester service "Cops Turn Blind Eye On" will make all areas unrestricted, allowing the player to fully explore these within the time limit.
