Approved IID Providers in Florida
Contact providers directly for current pricing and service center locations in Florida. Compare at least 2-3 providers before choosing — prices and service quality vary.
Restricted License with IID
Florida allows a hardship license with IID for qualifying offenders, permitting driving to work, school, church, and medical appointments. First offenders with standard BAC may get a hardship license without IID.
Tampering / Circumvention Penalties
Tampering with an IID in Florida is a first-degree misdemeanor punishable by up to 1 year in jail and a $1,000 fine. The IID period is extended and the hardship license may be revoked.
Early Removal
Florida does not allow early removal. The full court-ordered period must be served with compliance.
Florida-Specific Notes
Florida has a lifetime lookback period for DUI priors. A standard first-offense DUI with BAC under 0.15% does not require IID, but BAC of 0.15%+ or having a minor passenger triggers the mandatory IID requirement even for first offenders.
