A charge of driving under the influence (DUI) of alcohol is pretty serious no matter where you are — and Florida is no exception.

If you’re convicted of driving while intoxicated, you will definitely face fines and a suspended driver’s license. You could also be forced to attend addiction counseling, made to use an ignition interlock device, have your vehicle confiscated or be sentenced to jail.

How do you know if you’re over the legal limit?

Obviously, the best way to prevent a DUI is to never — ever — get behind the wheel after you’ve been drinking.
