What must an officer provide to justify a vehicle stop?

To justify a vehicle stop, an officer needs to present articulated facts and rational inferences related to the circumstances of the stop. This means that the officer must have a reasonable suspicion based on specific observations or facts that suggest criminal activity may be occurring. This standard is pivotal because it balances the enforcement of law with the protection of individual rights.

Simply observing a visible violation of traffic laws, while it can serve as a basis for stopping a vehicle, does not encompass the broader scope needed for less clear-cut situations. Witness testimonies supporting the stop may provide additional context but are not necessary to initiate the stop in the first place. Random checks for suspicious behavior lack the requisite legal threshold and could infringe upon civil liberties, as they do not rely on specific, articulable facts that could justify the intrusion of a stop. Therefore, the reliance on articulated facts and rational inferences captures the essential requirement for police action in these scenarios.
