Can you beat a DUI with a 18 bac?

depends. if the drink was taken with in minutes of the breath test then you may have a chance. because the alcohol reading would not be accurate that quick after a drink. but if not then ... i don't think so..

Try using www.DuiRights.com .. they know breathalyzer inaccuracies and help you fight the DUI charge. I used them and got the court to drop the bac reading because of the faulty police report.
