The title of this post may seem like a silly question. "Obviously if you drive with a blood alcohol level that exceeds 0.08, you can get a DUI" is probably what popped into your head, and that is correct. A blood alcohol content that exceeds 0.08 can earn you a drunk driving arrest. However, there are other circumstances in which you can get a DUI, or a different DUI charge, in the state of Minnesota.
For example, if you are underage, the state of Minnesota has a zero tolerance policy for drinking and driving. That means someone under the age of 21 can't have any alcohol in their system. Even a BAC of 0.01 for an underage driver can result in a DUI.
Another variation of the law is that if you have a blood alcohol level that exceeds 0.16, you could receive an "enhanced" (usually called "aggravated") DUI charge. This will carry tougher penalties and affect your life in a variety of ways.
Also, remember that in Minnesota if you are arrested for a DUI, you must adhere to the "implied consent" law. This law says that you have to consent to a breath, blood or urine test, though you are allowed to refuse a preliminary test.
As we hinted at above, there are many penalties that someone can face when they are arrested on suspicion of DUI. They could have their license suspended for months, or even a year depending on the severity of the charge or if there are past drunk driving offenses. Your vehicle could also be confiscated, or you could be required to use an ignition interlock.
