DUI contact consists of three phases. What is the first phase?

• A. Stop
• B. Vehicle in motion
• C. Pre-arrest screening
• D. Personal contact

Answer: (B)

First phase is the vehicle in motion. In this stage, the officer observes how the vehicle is being operated to spot objective signs that may indicate impairment—things like weaving, abrupt or inconsistent lane changes, unusual speed, or slow or delayed responses. These observable driving cues create the reasonable suspicion needed to justify stopping the vehicle. This phase relies on what is seen while the vehicle is moving, before any direct interaction with the driver. Once the stop is based on those observations, the encounter moves to the next phase (personal contact), followed by the pre-arrest screening to assess impairment and determine probable cause for arrest.
