What does Phase three of DUI detection focus on?

• A. Personal contact
• B. Pre-arrest screening
• C. Observation of the driver
• D. Vehicle operation analysis

Answer: (B)

Phase three of DUI detection specifically focuses on pre-arrest screening. This phase is critical because it involves gathering evidence to establish whether a driver is actually under the influence of alcohol or drugs. During pre-arrest screening, law enforcement officers conduct standardized field sobriety tests (SFSTs) that are designed to assess a person’s physical and cognitive abilities. These tests help officers determine if there is sufficient evidence to make an arrest for DUI. Understanding this phase is essential, as it combines observations from previous phases—such as initial contact and behavior—while utilizing specific testing methods to evaluate impairment. The information gathered during pre-arrest screening plays a pivotal role in supporting the officer's decision to proceed with an arrest, ensuring that the action taken is based on credible evidence.
