As officers administer standardized tests, the driver’s confidence gives way to visible anxiety. When her age is revealed, the situation changes instantly — for drivers under 21, the legal limit is far lower, leaving no room for error. The encounter ends with breath test results that confirm impairment and a hard lesson in how quickly poor decisions can carry adult consequences. This video documents the full stop from initial contact through testing, providing an unfiltered look at how DUI investigations unfold — and how fast “I’m fine” can turn into a life-altering moment.
