The “Right to Remain Silent” in New Jersey DWI Cases
Anyone who watches cop shows on television knows the warning police must read to a suspect when they place them under arrest. Known as the “Miranda warning,” after the U.S. Supreme Court’s 1966 decision in Miranda v. Arizona, it is legally required before police may formally interrogate a suspect. The list of rights identified in the Miranda warning are commonly known as Miranda rights. Miranda is considered a landmark decision in criminal justice. Although New Jersey’s driving while intoxicated (DWI) statute classifies the offense as a motor vehicle offense, rather than a “crime,” Miranda still applies when police take a DWI suspect into custody.
The Miranda decision arose from a confession signed by a suspect after hours of police interrogation, during which time he was never advised of various constitutional rights. The Supreme Court held that the confession was inadmissible because the defendant did not give it voluntarily, but instead under duress from police officers. The court further stated that police must stop an interrogation once an individual has asserted certain rights. It directed police to advise people of their rights before or at the time they are arrested. From this, the Miranda warning was born. The court would later specifically rule that Miranda applies to DWI cases in Berkemer v. McCarty in 1984.
The first right identified in the Miranda warning—the right to remain silent—refers to the Fifth Amendment’s protection against self-incrimination during “custodial interrogation.” The important question to consider regarding how Miranda applies in New Jersey DWI cases involves the definition of “custody,” as well as the meaning of “silence.” The two are closely related, as the caselaw shows, and DWI cases present at least one specific complication of the idea of the right to remain silent. In New Jersey and many other states, DWI suspects are required by law to provide breath samples for chemical testing. Courts have generally held that this does not violate the Fifth Amendment’s right against self-incrimination.
