What are the evidence gathering tasks in Phase 2 of a DWI investigation?

In a Driving While Intoxicated (DWI) investigation, Phase 2 focuses on evidence gathering tasks that involve direct interaction with the driver after the vehicle has been stopped. This phase is particularly important as it helps the officer assess the driver's condition and determine if there are signs of impairment through behavior and communication.

The correct choice encompasses "face-to-face observation and driver interview," which is vital for evaluating the driver’s physical and cognitive abilities. During this stage, officers observe the driver's demeanor, coordination, and the ability to articulate thoughts clearly. This interaction can provide crucial evidence of impairment, including potential indicators like slurred speech, the smell of alcohol, or any admissions of consuming alcohol or other intoxicants.

In contrast, other options focus on initial observations or assessments that do not delve into direct engagement with the driver, which is why they are not included in Phase 2. Observations made during the vehicle's operation or preliminary evaluations serve as background information but are not part of the critical evidence-gathering phase that directly assesses the driver.
