Am I in custody during a traffic stop?
An ordinary traffic stop is generally considered a temporary detention rather than Miranda custody. That's why officers can ask where you're coming from, whether you've had anything to drink, and similar questions without any warnings.
But a stop can become custodial if the restraint escalates. The total circumstances, not the label, control.
What moves a stop toward custody: being removed from the vehicle and placed in a patrol car, handcuffs, multiple officers surrounding the vehicle, extended duration well beyond the traffic purpose, or accusatory questioning that makes clear the person isn't leaving.
This matters most in DUI cases, where roadside questioning routinely produces the admissions that appear in the report. Those questions are generally admissible precisely because the stop wasn't custodial — which is a reason to be careful about what gets said before anyone is arrested.
The absence of a warning doesn't mean what you said can't be used. ---
