Restricted Areas

There are many restricted areas throughout the Grand Theft Auto series, which are generally off-limits to the public, and the protagonists will gain an instant Wanted Level if they trespass within these areas, regardless of whether they do it purposely or not. 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
Obszary o ograniczonym dostępie
 * In GTA V, 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, only Fort Zancudo will issue these warnings.
 * In GTA Online, Lester's service, "Cops Turn Blind Eye", will make all areas unrestricted (except for El Rubio's compound), allowing the player to fully explore these locations without resistance, within the time limit.
