What is required to initiate a motor vehicle stop?

To initiate a motor vehicle stop, the law requires reasonable suspicion. This standard allows law enforcement officers to make a brief stop of a vehicle if they observe behavior that suggests a possible violation of the law. Reasonable suspicion is based on specific and articulable facts, and it is a lower threshold than probable cause. It enables officers to stop a vehicle to investigate further, ensuring public safety and enforcing traffic laws.

In contrast, probable cause, while it is a stronger basis for actions such as making an arrest or searching a vehicle, is not necessary for an initial stop. Verbal consent from the driver is not a requirement for a stop, as officers can initiate a stop based on their observations and suspicions. Additionally, while a uniformed officer's presence may be beneficial for visibility and safety, the mere presence of a uniformed officer does not replace the need for reasonable suspicion to lawfully stop a vehicle.
