When must Miranda warnings be given, and what constitutes a valid waiver?

• A. After a suspect signs a written waiver.
• B. Only when the suspect requests counsel.
• C. Before custodial interrogation; a knowing, voluntary waiver of rights is required.
• D. Whenever police ask questions, regardless of custody.

Answer: (C)

The key idea is that Miranda warnings are a protection that kicks in only when a person is in custody and being interrogated. Warnings must be given before any custodial interrogation begins, and any waiver of those rights must be knowing and voluntary—the person must understand the rights and make a conscious choice to waive them. The waiver can be spoken or written, as long as it reflects a voluntary, informed decision under the totality of the circumstances. If the person asks for counsel, interrogation must stop until counsel is provided, and questioning generally cannot resume unless the person themselves reinitiates or counsel is waived. This choice captures both the custody condition for warnings and the requirement of a knowing, voluntary waiver, which is why it’s the best fit.
