When Does a Traffic Stop Become Custody? | Berkemer v. McCarty (Nuts & Bolts)

Description When does a traffic stop become “custody” for Miranda purposes? In this Nuts & Bolts edition of Cuffs & Case Law, we break down Berkemer v. McCarty (1984) and the line between a routine traffic stop and custodial interrogation. McCarty was pulled over after a trooper observed him weaving in and out of his lane. He was questioned, performed field sobriety tests, made incriminating statements, and was eventually arrested. But he was never given Miranda warnings before the questioning at the jail. The Supreme Court addressed two important questions: Does Miranda apply to misdemeanors? And when does a traffic stop become custodial? In this episode, we cover: • When a routine traffic stop is not custody • When a traffic stop can become custodial • Why the severity of the offense does not eliminate Miranda protections • Why the officer's private intentions don't determine whether someone is in custody • The importance of what a reasonable person in the suspect's position would understand • What changes once a suspect is formally arrested The key takeaway for law enforcement: you don't have to Mirandize everyone you pull over—but you need to recognize when the encounter has changed. Berkemer v. McCarty is one of the foundational cases for understanding Miranda, traffic stops, and custodial interrogation. We read case law so you don't have to. #BerkemerVMcCarty #MirandaRights #TrafficStop #CustodialInterrogation #FourthAmendment #PoliceTraining #CaseLaw #LawEnforcement
