Under the Fourth Amendment, when is a person seized?

• A. Seizure occurs only after physical restraint
• B. Seizure occurs as soon as blue lights are turned on
• C. Seizure occurs when police display authority and the person submits or is physically restrained
• D. Seizure occurs only after formal arrest

Answer: (C)

A seizure under the Fourth Amendment occurs when the police display authority in a way that a reasonable person would feel they are not free to leave, and the person submits to that authority or is physically restrained. This captures the moment the encounter becomes police-controlled, even if no arrest is made. Why this is the best answer: it combines two essential elements—the display of authority and the person’s submission or physical restraint. Without both elements, the situation may be just a voluntary or consensual encounter. For example, turning on lights or giving commands alone isn’t always a seizure unless the person feels they must stay and comply. Why the other ideas don’t fit: a seizure isn’t defined strictly by physical restraint, since someone can be seized without being grabbed if they submit to the officers’ authority. It isn’t limited to the moment of formal arrest, because seizures can occur well before an arrest. And relying only on blue lights doesn’t automatically equal a seizure unless it conveys to a reasonable person that they are not free to leave and they submit or are restrained.
