The three clues for DUI stimulus belong to which category?

• A. Stimulus clues
• B. Impairment clues
• C. BAC indicators
• D. Observation clues

Answer: (A)

The main idea here is that stimulus clues are about how a person responds to a test stimulus. When we say DUI stimulus clues, we’re focusing on the driver’s reaction to something presented during the test—things like how quickly they respond, whether they follow the given instruction, or whether their response is consistent with the task. These clues are tied to the stimulus itself, not to the person’s overall impairment level or to a chemical measurement. Impairment clues describe signs of impairment independent of a specific stimulus, BAC indicators come from chemical tests, and observation clues are broader notes about behavior and demeanor. Since the clues in question are specifically linked to the driver's response to the stimulus, they belong in the stimulus clues category.
