Question 1

What is an ignition interlock device?

Accepted Answer

An ignition interlock device (IID) is a breathalyzer installed in your vehicle. It requires a clean breath sample before the engine will start and may request random rolling retests while you drive.

Question 2

Who is required to install an IID in Florida?

Accepted Answer

Florida courts and the DHSMV may require an IID for DUI convictions, especially first offenses with high BAC, second or subsequent DUIs, or cases involving a minor in the vehicle.

Question 3

How long do I need an IID?

Accepted Answer

Typical durations range from six months for a first offense to two years or more for repeat offenses. The exact term is set by the court and DHSMV.

Question 4

How much does an IID cost in Florida?

Accepted Answer

Costs include a lease payment, setup fee, state fee, calibration processing, and optional protection or upgrade fees. Use our pricing calculator to estimate your total.

Question 5

How often must I calibrate the device?

Accepted Answer

Florida requires calibration every 30 days. Your provider will schedule appointments and upload data to the monitoring authority.

Question 6

Can someone else drive my car?

Accepted Answer

Yes, but anyone driving the vehicle must use the IID. All breath samples are logged to the vehicle, so you are responsible for any violations.

Question 7

What happens if the battery dies or I miss a calibration?

Accepted Answer

A missed calibration can be reported as a violation. Contact your provider immediately. Many providers offer 24/7 support for lockouts and missed appointments.

Question 8

What is a rolling retest?

Accepted Answer

A rolling retest is a breath sample requested randomly while the vehicle is running. You have a short window to provide the sample safely.

Question 9

When can the IID be removed?

Accepted Answer

Removal requires court or DHSMV authorization after you complete the required period without violations. Your provider will then schedule a removal appointment.

Question 10

Will an IID damage my vehicle?

Accepted Answer

Professional installation does not damage the vehicle. The device connects to the ignition wiring and is removed at the end of the program.

Question 11

Do I need special insurance?

Accepted Answer

Hardship licenses usually require FR-44 or SR-22 insurance. Even without a hardship license, your insurer and the court may require proof of coverage.
