That would depend on how you were charged within the court system. It could be found in your case file. *
In all US states a "driving under the influence" conviction is a felony, although the classification of the felony may depend upon the circumstances of the violation. Felony and most misdeameanor convictions become a permanent part of a convicted adult's criminal record. jaDepends. In Arizona if you have two or more DUI's within 5 years, if you get DUI will driving with a suspended, revoked, or restricted license, or if you have a child under the age of 15 in the car when you get pulled over. These are FELONY DUI's. So your answer is no, it's not a felony just because you went to jail.
That is if you live in Arizona
A first time DUI is usually charged as a misdemeanor, not a felony. If there was a car accident and someone was hurt, then the state could charge a person with a felony. Some states will consider a DUI a felony if it is the drivers second, offense, or third and so on. yes
