According to State v. Williams (2006), activating blue lights during police display constitutes what?

• A. Not a seizure
• B. A seizure
• C. A frisk
• D. A request for consent

Answer: (B)

Activating blue lights during police display signals a show of authority that a reasonable person would feel compelled to submit to, meaning the person is not free to leave. This is the essence of a seizure under the Fourth Amendment. State v. Williams (2006) addressed this exact scenario and held that the use of emergency lights constitutes a seizure because it alerts the driver to stop and comply with the officer’s authority, even without any physical restraint or weapons contact yet. It’s not about a frisk or a consent request—the lights themselves create the detention, not a separate protective pat-down or a voluntary permission. So the act of turning on those lights is a seizure.
