Ignition Interlock Devices After a Florida DUI: What Drivers Need to Know

Following a DUI arrest or conviction, Florida drivers are surprised to learn that an ignition interlock device can be mandated as part of their DUI penalties. This device has a profound impact on an individual’s life, employment, and finances. It is important to understand when an ignition interlock is mandated and how an attorney can help minimize or prevent such a requirement. 

What is an ignition interlock device? 

An ignition interlock device is a breath test device connected to a vehicle’s ignition. A breath sample must be given by the individual before the vehicle can start. If alcohol is detected by the device, the vehicle simply won’t start. Many IIDs require periodic “rolling retests” while driving a vehicle.

Florida law requires that IIDs be taken very seriously. Violators could face substantial penalties.

When does Florida require an ignition interlock?

Ignition interlock requirements in the State of Florida vary based on the circumstances of the arrest, which can involve the following:

• First DUI offense with a BAC of .15 or higher – You are required to use an ignition interlock device for at least six months.

• DUI with a minor in the vehicle – You are required to use an ignition interlock device for at least six months.

• Second DUI offense – IIDs are mandatory for at least one year after your arrest.
• Third or subsequent DUI defense – Mandatory IID for at least two years.

In some cases, judges might have the discretion to require an ignition interlock even if it’s not mandatory. 

How much does an ignition interlock device cost? 

Ignition interlock devices are paid for by the driver. Some of the costs include:

• Installation costs
• Monthly monitoring costs
• Maintenance costs

All these costs can accumulate to a significant amount, sometimes running to thousands of dollars. This is a significant cost to drivers, particularly to those who work.

Can an attorney help you avoid or reduce IID requirements?

Yes. An experienced Orlando DUI defense lawyer can:

• Challenge the lawfulness of the DUI stop or arrest
• Challenge the results of the breath or blood test
• Negotiate the charge to a crime that does not require IID installation
• Negotiate judicial discretion when the law does not require the installation of an IID

In some cases, a successful defense can eliminate the IID requirement entirely.

How ignition interlock devices affect your daily life

For many drivers, interlocks also present some practical challenges, such as:

• Difficulty in commuting to work
• Embarrassment and stigma
• Difficulty in shared or family vehicles
• Increased scrutiny by probation or monitoring agencies

Even a single violation, such as failing a test or failing to calibrate, can lead to an extension of interlock time.
