A DUI is considered a misdemeanor in most cases, although there are some circumstances that may elevate to a felony (for example, if you have been convicted of at least three DUIs in the last 10 years,if you caused someone injury or if you have already suffered a felony DUI, the fourth can be filed as a felony).

It can be charged as either a misdemeanor or a felony, depending on the facts of the case. For example, was there an accident with injuries? Would need more information to answer the question better.
