Mobile breathalyzers that cops use out on the stop give the cop a good estimation if a person is "drunk" or not. They are not admissable in court. Then there is a non-mobile unit that is a much bigger machine and much more accurate. I am not sure if this one is admissable in court. But blood is the determining factor. I've never heard of anyone getting a DUI without giving blood. Maybe it's happened but I know of nobody that has gotten a DUI and didn't get blood taken.
