Utah uses the Intoxilyzer 5000 and 8000 at its police stations. The manufacturer if very secretive about how this machine works, and the data received from it can vary tremendously depending on its calibration, operator error, user error, etc. It is not uncommon to see and hear of people blowing a .09 one minute and at the second breathalyzer blowing a .04. Those are drastic differences and may make a huge difference on whether a prosecutor decides to pursue charges or not. Make sure you have counsel that is familiar with this machine, how it works, and how to discredit its results if there is tampering, improper use, or down right manipulation by the police officers.
