The state of Minnesota, as is the case for every state in the country, recognizes the 0.08 blood alcohol limit for drivers. Anyone over that level can be arrested for driving under the influence of alcohol. However, there are other circumstances that can lead to a DUI arrest, just as there are many different consequences that can be applied to a person who charged with such an offense.
For example, depending on the circumstances of your case, you could be arrested for DUI with a BAC that is lower than 0.08. Additionally, if you are underage you can be arrested for DUI with a BAC that is lower than 0.08. For commercial drivers, the law is even stricter. If a commercial driver has a BAC of 0.04 or higher, they can be arrested for driving under the influence.
The consequences are tough to pin down for any specific DUI case, because they depend on the circumstances of the case. If your BAC was above 0.16, you are subject to much more punishing penalties. In general, you are at risk of thousands of dollars in fines as well as probation or jail time.
If your DUI is your first, then you would not necessarily need ignition interlock. For your second DUI or for three DUIs in a ten-year span, ignition interlock is a requirement. For your first DUI, if your BAC was 0.16 or higher, you will be subject to ignition interlock.
While the specifics matter, regardless of every detail, you should still talk with an attorney about your case so that your rights are protected.
