Florida DUI: Ignition Interlock Rules You Must Know

Florida’s ignition interlock rules require a breathalyzer device in your vehicle after a DUI to ensure sober driving. Non-compliance can extend penalties or revoke your license. With around one million DUI arrests annually in the U.S., per the CDC, understanding Florida DUI penalties is critical to protect your rights.

At RHINO Lawyers, our experienced attorneys craft tailored strategies to navigate these complex requirements, ensuring you’re not just another case. In this blog post, we will detail ignition interlock rules, from when they’re mandated to how to comply, empowering you to take charge. Let’s get started.

What is an Ignition Interlock Device?

An ignition interlock device (IID) is a small, handheld breathalyzer unit professionally installed into the dashboard of a vehicle. Its primary function is to prevent the car from starting if the driver has been drinking.

To begin a trip, the driver must provide a breath sample by blowing into the device. The IID then analyzes the breath for alcohol. If the blood alcohol content (BAC) is at or above the pre-set limit, typically 0.02% in Florida, the device will lock the vehicle’s ignition, rendering it impossible to start.

The technology is designed to be foolproof. Beyond the initial breath sample required to start the car, the device will prompt the driver for random “rolling retests” while the vehicle is in motion. This feature prevents a sober friend from providing the initial sample and ensures that the driver remains alcohol-free throughout the journey.

The main purpose of the IID is twofold: it acts as a deterrent to drinking and driving, and it allows individuals who have been convicted of a DUI to maintain a limited form of mobility for work, school, and other necessary activities, all while protecting public safety.

Who Must Install an IID in Florida?

Florida law is clear about who must install an ignition interlock device (IID) following a DUI conviction. The requirement escalates with each offense, ensuring that repeat offenders face increasingly strict measures.

For a first-time DUI conviction, an IID is not always mandatory, but it is required if the driver’s blood alcohol content was 0.15% or higher, or if a minor was in the vehicle at the time of the offense. In such cases, the device must be used for at least six months.

The penalties become more severe for subsequent offenses. A second DUI conviction necessitates an IID for a minimum of one year. A third conviction increases this requirement to at least two years. In the case of a fourth or subsequent DUI, the driver could be required to use an IID for a period of five years.

It’s also important to note that refusing to take a breath, blood, or urine test when requested by an officer can result in an automatic IID installation requirement, even for a first offense. This is because Florida’s implied consent laws mean that by operating a vehicle, you have already consented to such tests.

How Long Do You Have to Use an IID?

The length of time you must use an ignition interlock device (IID) in Florida is directly tied to the specifics of your DUI conviction. As noted above, for a first offense, if an IID is required, it must be installed for a minimum of six months. This is often a mandatory condition for first-time offenders who had a blood alcohol content of 0.15% or higher, or if a minor was in the vehicle at the time of the offense.

For repeat offenders, the required duration increases significantly. A second DUI conviction carries a mandatory IID period of at least one year. If that second offense involved a BAC of 0.15% or higher, or a minor was in the vehicle, the requirement extends to at least two years.

A third DUI conviction also necessitates an IID for a minimum of two years. If you are convicted of a fourth or subsequent DUI offense, the device will be required for at least five years as a condition for a hardship license. These requirements are a critical part of the process for regaining limited driving privileges.

Frequently Asked Questions

What if I Don’t Own a Car?

The ignition interlock device (IID) requirement in Florida is tied to your driving privilege, not a specific vehicle. Therefore, if you are ordered to have an IID, you must install one in any vehicle you intend to operate.

This includes a car you borrow from a friend or family member, or even a company vehicle you use for work. It is a violation to drive any vehicle that does not have a functioning IID installed during your required period.

Can Someone Else Blow Into the IID for Me?

No, this is a serious violation of Florida law and can lead to significant penalties. Florida Statutes prohibit a restricted driver from asking another person to provide a breath sample and also make it unlawful for a third party to do so. Modern IIDs are equipped with cameras to prevent this type of circumvention.

Can the Device Fail for Reasons Other Than Alcohol?

Yes, it is possible for an IID to register a false positive due to mouth alcohol. Which can come from sources other than alcoholic beverages. Common culprits include:

  • Certain mouthwashes
  • Breath sprays, cough medicines
  • Some energy drinks or foods

To avoid a false positive, it is highly recommended to rinse your mouth with water. Then wait a few minutes before providing a breath sample.

Who Pays for the IID?

The individual who is required to have the IID is responsible for all associated costs. This includes the initial installation fee, monthly rental or leasing fees, and fees for regular calibration and maintenance.

There are no state-sponsored programs to cover these costs for most offenders. Although some providers may offer payment plans or assistance for those who can prove financial hardship.
