In DWI investigations, how is detection defined?

• A. A single observation by an officer
• B. The entire process of gathering information
• C. A chemical test result
• D. The traffic stop duration

Answer: (B)

Detection in a DWI investigation is the process of gathering information throughout the encounter that leads the officer to recognize impairment. It isn’t based on a single cue or a test result alone; it comes from the overall accumulation of observations, behaviors, statements, and testing that together indicate impairment and justify further action. A lone observation might raise suspicion, but true detection rests on the combined evidence gathered during the investigation. Chemical test results provide proof of intoxication, but they’re not what detection itself refers to. The length of a traffic stop doesn’t determine detection either; it’s the information collected during the investigation that matters.
