What is the difference between a DUI and DUAC?

While the answer is simple, understanding the difference can be challenging, so lets get to it. DUI stands for driving under the influence (of alcohol or drugs). The key here is the police pulled you over presumably because you were diving badly and through their investigation they discovered you were intoxicated on alcohol or some other drug. Another key is that you can be intoxicated on alcohol or some other drug, not just alcohol.
DUAC stands for driving with an unlawful alcohol concentration. This is the DUI per se law. What this means is if you meet the criteria set in this law, the court assumes you were too drunk to drive. Boiled down, it means if you were driving and then blew over .08%, the state assumes you were too drunk to drive, even if you were driving fine and were pulled over for speeding or failing to use a turn signal. Even if you passed all the field sobriety tests, you can still be convicted under this law. The key here is the state only has to show you were driving and had more than .08% alcohol concentration in your blood. They do not have to show you were not driving well. Another key here is this law only applies to alcohol, not other drugs too. This is because the breath test you were given only detects alcohol, not other drugs. I hope this helps clear away some of the confusion about these two companion laws.

    Thank-you for the info…My concern is how can my friend get out of jail for a DUAC anf open container? He was arrested last Thursday 10-23-2010 and is still in jail. His estranged wife has went and took his truck and some personel property. I do not have the cash for a bondsman..his bond is 2,562.00 why for 1st offense. What do I do next? I have not had any experience with this kind thing before and do not know where to turn.
