False Positives or Inaccurate Breathalyzer Results

Law enforcement is supposed to maintain a 20-minute observation period in which they are present with the driver to ensure that none of that has happened. Drinking after someone is first pulled over could affect the BAC results. Chewing gum, mouthwash, and cold medicine can all effect false positives.
