Florida Ignition Interlock Requirements (2026): Costs & Approved Providers

Florida’s ignition interlock is court-ordered and administered by FLHSMV via a “P” restriction on your license. The term must be served continuously — any early removal restarts the clock from zero with no credit. Only three providers are approved statewide. Here’s who needs one, how long, and what it costs.

Do you need an interlock in Florida?

Florida is not an all-offender state, but the mandatory triggers are broad enough that most DUI defendants will face an interlock. It is mandatory on a first offense if your BAC was 0.15 or higher, or if a minor was in the vehicle — no judicial discretion. For a standard first DUI under 0.15 with no minor present, the judge may order one at sentencing but is not required to.

For second and subsequent offenses, the interlock is mandatory regardless of BAC. Courts impose it as a condition of any hardship or reinstatement, and FLHSMV requires it before your license is restored.

The “continuous” rule is Florida’s most important detail. Florida law requires the IID term to be served without interruption (FS §322.2715). If the device is removed early — for any reason — the entire term restarts from zero with no credit for time already served. Do not remove the device, switch providers, or let your provider’s lease lapse until FLHSMV confirms your term is complete.

Florida FLHSMV-approved providers

Only three providers are currently approved in Florida. Note: Intoxalock, LifeSafer, and Dräger/RoadGuard are not on Florida’s approved list — installing with any unapproved provider will not satisfy your requirement.

ProviderMonthly est.Coverage
Smart Start $70–100 Statewide 800-831-3299
Guardian Interlock $65–95 Statewide 800-499-0994
ALCOLOCK $60–90 Statewide 866-700-9300

Confirm your provider’s current approval on the FLHSMV IID page before signing. Using an unapproved provider will not satisfy your court order and will not count toward your term.

Financial hardship? Florida has no formal state indigent fund for IID costs. However, the court may allocate part of your DUI fine to defray installation costs for defendants who demonstrate at sentencing that they cannot pay. There are no published income criteria — ask your attorney to raise this at sentencing if cost is a barrier.

How to get installed — 5 steps

  1. Confirm whether your court order mandates an IID or whether it is a condition of your hardship license — your paperwork will specify.
  2. Call one of the three approved providers and book installation. Do not use any unapproved provider.
  3. Bring your vehicle, court order, and ID. Installation takes 60–90 minutes. A $12 state fee is included.
  4. Have your license updated with the “P” restriction at FLHSMV. Pay the $75 reinstatement and $130 DUI administrative fees.
  5. Serve the full continuous term. Do not remove the device for any reason until FLHSMV confirms completion — early removal restarts your term from zero.

Violations — what triggers a DUI program referral

Florida’s violation system works differently from most states: rather than automatically adding months, violations trigger a referral back to your DUI program within 10 days. Violations include two high-BAC startup failures, a missed or failed rolling retest, and tampering or circumvention. The DUI program then reports to the court, which determines the consequence — which can include restarting your IID term. Additionally, any early removal of the device restarts the term from zero with no credit for time served.

Florida requires FR-44 — not SR-22. After a DUI conviction, Florida requires an FR-44 filing for 3 years from reinstatement. The FR-44 demands significantly higher liability limits than standard SR-22 states: $100k/$300k bodily injury and $50k property damage (or $350k CSL). See Florida FR-44 costs and cheapest carriers →

Florida DUI interlock FAQ

Do I need an interlock for a first DUI in Florida?
It depends. If your BAC was 0.15 or higher, or a minor was in the vehicle, the interlock is mandatory for at least 6 continuous months. For a standard first DUI under 0.15 with no minor present, it’s at the court’s discretion — the judge may or may not order it at sentencing.
Which providers are approved in Florida?
Only Smart Start, Guardian Interlock, and ALCOLOCK are approved by FLHSMV. Intoxalock, LifeSafer, and Dräger/RoadGuard are not on Florida’s approved list. Using an unapproved provider will not satisfy your court order and will not count toward your required term.
What happens if I remove the device early in Florida?
Your entire term restarts from zero with no credit for time already served. Florida requires the term to be served continuously — any interruption resets the clock completely. Do not remove, switch providers, or let your lease lapse until FLHSMV confirms your term is complete.
How long will I have the interlock?
At least 6 continuous months for a first offense with mandatory triggers (BAC 0.15+ or minor). At least 1 year for a second offense, 2 years for a second with BAC 0.15+ or minor. At least 2 years for a third offense. At least 5 years for a fourth or beyond.
Does Florida require SR-22 insurance?
No — Florida requires an FR-44, not an SR-22. The FR-44 requires significantly higher liability limits: $100,000/$300,000 bodily injury and $50,000 property damage (or $350,000 combined single limit). It must be maintained for 3 years from your reinstatement date. See our Florida FR-44 page for carrier comparisons and costs.
