Florida IID Requirements After a DUI: Step by Step

Where Your Requirement Comes From

Ignition interlock requirements in Florida arrive from two directions, and your case may involve both:

• The court. Under Florida Statute 316.1937, judges order an IID at sentencing. A first DUI can carry up to 6 months if the judge orders it - and at least 6 months is mandatory when your BAC was 0.15 or higher, or a minor was in the vehicle. A second DUI means at least 1 year, and a third at least 2 years.
• The FLHSMV. The state can require an IID as a condition of reinstating your license or granting a hardship license, separate from anything the judge ordered.

Your court order or FLHSMV notice controls your exact situation - read it before any guide, including this one. First offense? See the first-DUI requirements breakdown.

Step 1: Enroll in a State-Approved DUI Program

Florida requires enrollment in a licensed DUI program before it will reinstate any driving privileges after a DUI. You don't have to finish the course before everything else moves - proof of enrollment is what the FLHSMV and the Bureau of Administrative Reviews ask for at this stage. Enroll in the first days after your arrest or conviction; completion is required before final reinstatement, and the certificate takes time to process.

Step 2: File FR-44 Insurance

DUI-related reinstatements in Florida require an FR-44 certificate - proof of liability insurance at limits far higher than the state minimum. Your insurer files it directly with the FLHSMV, and it typically must stay in force for three years. Not every insurer writes FR-44 policies, so ask up front. Our FR-44 vs. SR-22 guide explains the filing, the costs, and the common mistakes.

Step 3: Install the IID at an Approved Service Center

With the paperwork moving, book your installation at a state-approved service center. Bring your court order or FLHSMV notice, a valid ID, your vehicle registration, and proof of insurance. The appointment takes 60 to 90 minutes: the technician wires the device into your vehicle, trains you on breath tests and rolling retests, and hands you a certificate of installation. If someone else owns the vehicle, bring their written consent. We run 27 service centers across Florida, so there's usually one near your commute.

Step 4: Get the Installation on Record

The certificate of installation is the document that activates everything else. It goes to the FLHSMV - and to the court, if your order requires it - to prove you've complied. If you're pursuing a hardship license, the IID normally must be installed before your restricted privileges begin, so schedule installation ahead of your Bureau of Administrative Reviews appointment, not after.

Step 5: Stay Compliant for Your Full Period

Once installed, your requirement clock runs while the device is in the car and you're in compliance. That means:

• Calibration appointments every 30 days - here's what happens at one
• No failed tests, missed retests, or tamper flags - learn what counts as a violation
• Continuous FR-44 coverage - a lapse can suspend you again mid-program

Your device reports to the FLHSMV at every service visit, and violations in your final months can extend the requirement.

How Long the Whole Process Takes

From conviction to legal driving, organized drivers typically move through steps 1 to 4 in two to four weeks - DUI program enrollment and the FR-44 filing are same-week tasks, and installation appointments are usually available within days. The IID period itself is the long middle: 6 months, a year, or more depending on your offense (see how long an IID lasts). The timeline only stretches when paperwork stalls, so treat every certificate and filing as urgent.

Step 6: Get Authorization, Then Remove the Device

You don't remove the IID when the calendar says so - you remove it when the FLHSMV or the court authorizes removal. The sequence: serve your full period → keep a clean recent record → obtain authorization → schedule removal at your service center → the center reports de-installation and your full driving privileges are restored. Removing early without authorization is the most expensive mistake in the program.
