This is a 3 minute video that shows a failed field sobriety test. The police officer follows her for a few minutes, and you can tell from her behavior that something is wrong. The lady is then forced to take a field sobriety test, and she fails it miserably. The defendant is arrested and booked for DUI.
This is an example of the type of evidence that the prosecutors can use against you in a trial for drinking and driving. The evidence is very convincing, and you lawyer would rather not have it admitted.
