What is required for a law enforcement officer to perform a traffic stop?

For a law enforcement officer to perform a traffic stop, the requirement is primarily based on the observation of a minor traffic violation. This principle is rooted in the legal authority granted to law enforcement to enforce traffic laws and ensure public safety on the roads.

When an officer witnesses a traffic infraction, such as speeding, running a stop sign, or failing to use a turn signal, they have reasonable suspicion to initiate a stop. This reasonable suspicion is a critical component of law enforcement actions, enabling officers to address potential violations effectively.

The other options presented do not reflect the common legal standards guiding traffic stops. An arrest warrant is not necessary for a traffic stop; rather, the officer's personal observation of a violation suffices. Similarly, a public complaint or a directive from a higher authority is not required for initiating a stop; the officer's direct observation plays the fundamental role in these scenarios.
