The length of DUI license suspension periods vary. It depends on the nature of the offense, breath test results, and how many previous DUI convictions a person already has. What the law says in that area is also an important factor. In Florida, a first offense usually results in a suspension of between 6 months and a year. It is sometimes possible to get a license back earlier by enrolling in or completing DUI school and treatment. Attorneys know what the options are.
