When must an officer provide Miranda warnings?

An officer must provide Miranda warnings before conducting a custodial interrogation because these warnings are designed to inform individuals of their rights while in custody, particularly the right to remain silent and the right to an attorney. The purpose is to protect the Fifth Amendment right against self-incrimination.

Custodial interrogation refers to questioning that occurs after a person has been taken into custody or otherwise deprived of their freedom in a significant way. If an officer does not provide these warnings during such an interrogation, any statements made by the suspect may not be admissible in court.

While making an arrest is a significant action, it is not the sole trigger for Miranda warnings. They are specifically required when the individual is both in custody and subject to interrogation. Additionally, the requirement does not apply during routine witness questioning or traffic stops unless those circumstances escalate to a custodial situation. Therefore, the correct context for requiring Miranda warnings is during custodial interrogations, making the first option the accurate choice.
