Florida ignition interlock & DUI requirements
Florida requires an ignition interlock after a first DUI only at a BAC of 0.15 or higher (at least 6 continuous months); below that threshold it is not automatic, though other circumstances set by the statute can still require one. A repeat offense carries at least 1 continuous year.

SR-22 requirement
An SR-22 is a certificate an insurer files with the state to confirm that a driver carries the liability coverage the state requires. Some states use an FR-44 or a different form for alcohol-related offenses; where Florida does, the sources below say so.
| SR-22 filing required after a DUI | Yes |
|---|---|
| Filing period | 3 years |
Florida requires an FR-44 (not SR-22) for DUI convictions after October 1, 2007: bodily injury liability of $100,000/$300,000 and property damage liability of $50,000 (or $350,000 combined single limits) per Fla. Stat. § 324.023, maintained for three years from the date of reinstatement (FLHSMV DUI FAQ).

Exemptions and special cases
Four questions readers ask once an interlock is ordered — motorcycles, employer vehicles, medical inability to give a breath sample, and reduced-cost programs — answered as Florida's interlock program page or statute states them.
| Question | Florida rule |
|---|---|
| Motorcycles | Motorcycles are exempt from the requirement For the FLHSMV ignition-interlock rules (Fla. Admin. Code ch. 15A-9, Breath Alcohol Ignition Interlock Devices), 'motor vehicle' is defined as any self-propelled motor vehicle not operated upon rails or guideway 'but not including any motorcycle, bicycle, motorized scooter, electric personal assistive mobility device, or moped', and an ignition interlock device is defined as a breath alcohol analyzer connected to a motor vehicle's ignition. Fla. Stat. § 322.2715(1) requires the device on all vehicles individually or jointly leased or owned and routinely operated by the convicted person; the FLHSMV Ignition Interlock Program page and IID FAQ do not separately address riding a motorcycle on a license carrying the 'P' (IID) restriction. What the source says“(17) Motor vehicle. Any self-propelled motor vehicle not operated upon rails or guideway, but not including any motorcycle, bicycle, motorized scooter, electric personal assistive mobility device, or moped.” |
| Employer-owned vehicle | Exempt with conditions Fla. Stat. § 316.1937(7): a person required to operate a motor vehicle in the course and scope of employment may operate a vehicle owned or leased by the employer without an IID if the employer has been notified of the driving-privilege restriction; proof of that notification must be with the vehicle; the exemption does not apply if the business entity that owns the vehicle is owned or controlled by the restricted person. FLHSMV IID FAQ: the customer must meet the IID requirements, hold a valid license with a 'P' restriction and have written permission from the employer; the employer's vehicle may then be operated for job-related purposes without the IID, and the employer's permission letter is to be kept with the vehicle and provided to law enforcement if stopped. What the source says“the person may operate that vehicle without installation of an approved ignition interlock device if the employer has been notified of such driving privilege restriction. Proof of that notification must be with the vehicle. This employment exemption does not apply, however, if the business entity” |
| Unable to provide a breath sample | Available Fla. Stat. § 322.2715(1): consideration may be given to individuals having a documented medical condition that would prohibit the device from functioning normally. Fla. Admin. Code r. 15A-9.0041: (1) a minimum breath sample of 1.0 litres per blow (instead of the standard 1.5 litres) may be considered if a licensed pulmonologist certifies a lung condition rendering the person incapable of blowing a sample, after review by the Medical Review Board; (2) where a medical condition makes the person incapable of properly operating the device, the person may submit a medical report from an appropriate specialist to the Medical Review Board, which issues a finding, and the IID requirement may be waived or modified. If a medical waiver is granted: a person seeking a restricted (hardship) license is not entitled to it until the required IID installation period expires (in addition to the § 322.271 time requirements), and a person seeking permanent reinstatement must be restricted to an employment-purposes-only license and be supervised by a licensed DUI program until the IID period expires (§ 322.2715(1)). What the source says“the convicted person may submit a medical report from an appropriate specialist to the Medical Review Board who shall review and issue a finding of the medical incapacity. Pursuant to the authority under Section 322.2715, F.S., the use of the ignition interlock requirement may be waived or modified.” |
| Reduced-cost / indigent program | Available — Indigent Guidelines (FLHSMV Ignition Interlock Program page heading) FLHSMV: if the court determines the convicted person is unable to pay for installation of the IID, the court may order that a portion of the fine paid for a § 316.193 violation be allocated to defray the cost of installation. Fla. Stat. § 316.1937(2)(d) directs the court, when imposing an IID, to determine the person's ability to pay for installation if the person claims inability to pay. Only the installation cost is addressed; monthly lease/monitoring fees, the $12 interlock fee remitted to FLHSMV and the reinstatement fees are not stated as reduced, no income threshold is stated, and the determination is made by the court, not FLHSMV. What the source says“If the court determines that the convicted person is unable to pay for the installation of the IID, the court may order that a portion of the fine paid by the person for a violation of section 316.193 , Florida Statutes, be allocated to defray the cost of installation.” |
| No reinstatement without a vehicle | To reinstate, the customer must have an IID installed in a vehicle they own and/or routinely operate; FLHSMV states there is no reinstatement provision for people who do not own and/or routinely operate a vehicle. What the source says“In order to reinstate a driver license, the customer must have an IID installed in a vehicle that he/she owns and/or routinely operates. There is no reinstatement provision for people who do not own and/or routinely operate a vehicle.” |
| Moving out of state | For a Florida license holder the IID requirement follows the driver; Florida will not clear the record until all requirements are met, and an IID provider is to be contacted to coordinate out-of-state installation and service. What the source says“If the customer has a Florida license, the requirement follows them. Florida will not clear the driver record until all requirements are met. Please contact an IID provider to coordinate installation and service out-of-state.” |
| Court order or other documentation about whether the IID applies | A customer may present a court order or other documentation to a FLHSMV Bureau of Administrative Reviews office for consideration of whether the IID is required. What the source says“Yes. A customer may present a court order or other documentation to a local DHSMV Bureau of Administrative Reviews (BAR) office for consideration.” |
| Medical waiver and hardship/restricted license timing | Under r. 15A-9.0041(2)(a)-(b), a person granted a medical waiver is not entitled to a hardship license, or to permanent reinstatement, until the IID installation period prescribed in § 322.2715 expires. What the source says“If a medical waiver has been approved for a convicted person seeking a hardship license, the convicted person shall not be entitled to a hardship license until the required installation period of the ignition interlock device prescribed in Section 322.2715, F.S. expires” |
