Florida requires an Ignition Interlock Device (IID) for many DUI convictions. Understanding when IID is mandatory, how long it’s required, and how it interacts with your FR44 insurance and license reinstatement is essential for getting back on the road legally.

When IID Is Required in Florida

Conviction Type	IID Requirement	Duration
First DUI conviction	Mandatory with hardship license	6 months minimum
First DUI with BAC 0.15%+ or minor in vehicle	Mandatory	6 months minimum (often extended)
Second DUI conviction	Mandatory	At least 1 year
Second DUI within 5 years	Mandatory	At least 2 years
Third DUI	Mandatory	At least 2 years
Court discretion (first DUI)	Judge may order IID even without mandatory trigger	Varies by order

How IID and FR44 Interact

IID and FR44 are parallel requirements — both stem from your DUI conviction, but they are administered separately:

• FR44 is an insurance filing managed by your insurer and FLHSMV
• IID is a device requirement managed by FLHSMV and an approved IID vendor
• You must meet BOTH requirements to get a hardship license or full reinstatement
• FR44 cannot substitute for IID compliance, and IID completion does not remove the FR44 requirement

Florida IID Requirements: The Device Itself

An approved IID must be installed by an FLHSMV-approved vendor. The device:

• Requires a breath sample before the engine will start
• Requires rolling retests at random intervals while driving
• Records all test results, which are transmitted to FLHSMV monthly
• Cannot be removed or tampered with without FLHSMV notification
• Must be serviced every 30-60 days (varies by vendor)

Cost of IID in Florida

• Installation: 5-50 (one-time)
• Monthly monitoring/lease: 0-0/month
• Removal fee: 0-5
• Total for 6-month requirement: Approximately 00-00
• Total for 2-year requirement: Approximately ,600-,400

Florida has a hardship waiver for indigent defendants who cannot afford IID installation — contact FLHSMV or your attorney for eligibility requirements.

Approved IID Vendors in Florida

FLHSMV maintains an approved vendor list. Major providers operating in Florida include Smart Start, Intoxalock, Guardian Interlock, and Drager. Use only FLHSMV-approved vendors — unauthorized devices do not satisfy the requirement.

What Happens If You Violate IID Requirements

• Failed breath test (alcohol detected) → logged and reported to FLHSMV
• Missed rolling retest → treated as failed test
• Tampering or circumvention → additional DUI charges, license re-revocation
• Driving a vehicle without IID during restricted period → criminal violation

Getting FR44 with IID Restriction

Your FR44 policy covers driving during your IID restriction period. When you get your hardship license with IID requirement, your insurer files the FR44 with FLHSMV, and the hardship license is endorsed with the IID restriction. After completing the IID period and FR44 period (which runs concurrently and may extend beyond IID), your full license is restored.
