Confirm the device, provider and written quote

Check the responsible authority’s current approval information for the particular device and installer. Request the billing unit, included services, actual paid visit schedule, taxes, fees and removal terms in writing. Confirm financial assistance separately.

Add your own quoted charges in the IID worksheet. Unknown charges stay unknown; no local price or appointment count is assumed.

Restricted License with IID

Available

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.
