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.
| All-offender state? | No — standard first offense is court discretion; mandatory triggers apply |
| Mandatory on 1st offense if | BAC 0.15 or higher, OR a minor was in the vehicle (FS §316.193(4); §322.2715(3)(b)) |
| Court discretion on 1st offense | BAC under 0.15, no minor — judge may order at sentencing (FS §316.193(2)(c)) |
| Duration — 1st offense (mandatory) | At least 6 continuous months |
| Duration — 2nd offense | At least 1 continuous year; at least 2 years if BAC 0.15+ or minor in vehicle |
| Duration — 3rd offense | At least 2 continuous years |
| Duration — 4th+ offense | At least 5 years (as hardship license condition) |
| Critical: “continuous” requirement | Term must be served without interruption — early removal restarts the full term with zero credit |
| How administered | “P” restriction on license; FLHSMV requires before reinstatement (FS §322.2715) |
| Approved providers | Smart Start, Guardian, ALCOLOCK only |
| State fees | $75 revocation reinstatement + $130 DUI administrative fee; $12/install remitted to state trust fund |
| Insurance required | FR-44 (not SR-22) — 3 years from reinstatement with higher liability limits |
| Governing law | FS §316.193; §316.1937; §322.2715; §324.023 |
| Offense term | DUI (Driving Under the Influence) |
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.
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.
| Provider | Monthly 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.

How to get installed — 5 steps
- Confirm whether your court order mandates an IID or whether it is a condition of your hardship license — your paperwork will specify.
- Call one of the three approved providers and book installation. Do not use any unapproved provider.
- Bring your vehicle, court order, and ID. Installation takes 60–90 minutes. A $12 state fee is included.
- Have your license updated with the “P” restriction at FLHSMV. Pay the $75 reinstatement and $130 DUI administrative fees.
- 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.
