Phrase 1 of 4 — Detention status
"Am I being detained, or am I free to go?"
Why it works: Forces the officer to state whether you are legally obligated to stay — a critical distinction that governs your rights for the rest of the stop. Terry v. Ohio, 1968.

Phrase 2 of 4 — Consent to search
"I do not consent to any searches."
Why it works: Without consent, officers need probable cause to search your vehicle. Saying this clearly preserves your rights if a search is later contested. Florida v. Bostick, 1992.

Phrase 3 of 4 — Right to silence
"I am going to remain silent."
Why it works: You have the right to remain silent under the 5th Amendment. You must clearly invoke it — silence alone is not an invocation. State it once and stop talking. Salinas v. Texas, 2013.

Phrase 4 of 4 — Departure line
"Am I free to leave?"
Why it works: The driver asks one clarifying question at the end of the stop. A “yes” means leave calmly; a “no” means you remain detained — stay silent and wait for counsel. Terry v. Ohio, 1968; Rodriguez v. United States, 2015.

Cue 1 of 3 — Tone
"Lower your voice. Speak slowly."
Why this works: Crisis negotiation research (McMains & Mullins; Conflict Communications) shows a slow vocal tone lowers the officer's perceived-threat load and triggers de-escalation scripts on the officer side.
Cue 2 of 3 — Breathing
"Settle your breathing. Long exhale."
Why this works: Diaphragmatic exhalation activates the parasympathetic response and visibly lowers your physiological arousal to the officer (Gross, emotion-regulation research; Levenson, autonomic specificity).
Cue 3 of 3 — Visibility
"Keep hands visible and still."
Why this works: Non-verbal transparency cues are the strongest predictor of an officer's "cooperative" classification during traffic stops (Navarro, Louder Than Words; Mehrabian immediacy research).
