In Florida, a DUI does not qualify as a felony unless you have had multiple DUI arrests in the past or have injured another person. If you have received your third DUI within 10 years or a DUI with injury, it becomes a third-degree felony with fines up to $5,000 and a prison term of up to 5 years.
For DUI manslaughter, it is a second-degree felony with a fine of up to $10,000 and a prison sentence of up to 15 years. If you leave the scene of an accident resulting in a DUI manslaughter, it is a first-degree felony with a fine of up to $10,000 and a prison sentence of up to 30 years.
