If a suspect is read their rights but is not in custody, are the Miranda warnings necessary?

The Miranda warnings are designed to protect a suspect's Fifth Amendment right against self-incrimination and are required only when a person is under custodial interrogation. If a suspect is not in custody, they are not subjected to the type of compulsion that the Miranda warnings are intended to address. Custody implies that a reasonable person would feel they are not free to leave due to an authority figure's presence or actions. Therefore, if the individual is free to leave and not subjected to interrogative pressure by law enforcement, the necessity for Miranda warnings does not arise. This concept is fundamental to understanding when these rights must be administered and helps law enforcement not overstep legal boundaries when conversing with individuals who are not in custody.
