The coin-operated breathalyzer in the bar said I was under the legal limit, but later I received a DUI. Can I sue the bar owner?
Such machines are entirely designed for entertainment value and should not be relied upon as an authority for determining what your breath alcohol content is at any given time. Plus, once you leave the establishment, your BAC will naturally fluctuate, so even if you scored under the legal limit when using the machine in the bar, it could realistically be higher ten to fifteen minutes later. I don’t think you would have any chance of suing successfully.
