• You can be convicted of a DUI in Florida even if your BAC is under 0.08% if the officer proves your “normal faculties” were impaired by alcohol or drugs.

• Enhanced BAC (.15 or higher): Fines and jail sentences increase significantly if your BAC is 0.15% or higher, or if a minor was a passenger in the vehicle
