Only if you damage the property or person of another. A misd in the 2st degree is punishable for up to 1 year in jail. A first time DUI with no damage to property or person has a maximum sentence of 6 months in jail.
Relevant section of statute pasted below.

By case law, a first time DUI in the state of Florida is considered a first degree misdemeanor, even though (assuming no accident) it is a maximum of 6 months jail. I know of no other misdemeanor of any degree that is treated that way. So DUI is unique in Florida law for that reason.
