In Michigan to charge you with Operating While Intoxicated (OWI the Michigan equivalent of a DUI) they will need evidence of your blood alcohol content (BAC) being above the legal limit. That could be proved through either a breath, blood, or urine test. If they fail to have any of that, they shouldn't be able to sustain a conviction for OWI. However, there is a lesser charge known as Operating While Visibly Impaired, more commonly known as OWVI or Impaired Driving. It is a frequent plea bargain for first time DUI offenders. With this charge, the prosecution would not need to prove a certain BAC, but that it is evident from viewing or from observation that you were intoxicated. Here they look at certain factors: bloodshot eyes, slurred speech, balance and motor skills, coherency, acclimated as to time and date, eractic driving, etc. Check with what you are charged with and review the statute and jury instructions to see what the prosecutor has to prove. Consult with an experienced DUI attorney for a case review. These charges carry severe penalties so it is never advisable to proceed without legal counsel.
