During which phase of DUI detection does the officer speak with the driver face to face?

In the context of DUI detection, the second phase is when the officer engages in a face-to-face conversation with the driver. This interaction is crucial as it allows the officer to observe the driver's behavior, demeanor, and physical indicators that may suggest impairment. During this phase, the officer typically asks a series of questions to assess the driver's ability to respond coherently and to gauge their overall state. The information gathered through this direct communication is vital in determining whether further investigation, such as field sobriety tests, is warranted. Additionally, this phase enables the officer to notice signs such as slurred speech, the smell of alcohol, or other behaviors that may further indicate intoxication.
