Florida Ignition Interlock Device Explained
Having an ignition interlock device, or IID, installed on a vehicle is a common sentence in many DUI cases. The device is designed to keep motorists who have been convicted of driving under the influence from doing so in the future. The IID is cumbersome, costly and embarrassing.
How the IID Works
An ignition interlock device functions by testing the breath of the driver each time he attempts to start his vehicle, and then at timed intervals during his time behind the wheel. If you are sentenced to an IID, the device will be installed in your vehicle, usually in the glove compartment. Each time you attempt to start your car, you must blow into the alcohol sensor unit, which will be on the dashboard. If your blood alcohol content is over a limit set by the court, your car will not start. You will also have to submit to “rolling tests” as you operate your vehicle, which will occur randomly from five to 30 minutes after you start your car. If you fail either the first or any of the rolling tests, the IID will sound an alarm that will go off until you stop your vehicle. The details of your BAC level are recorded each time you blow so that the state will be able to tell if you have been attempting to drive under the influence.
Who Is Required to Have an IID?
The results of your breath test and the number of previous DUIs you have on your record will determine the duration of your IID sentence. If you are a first-time DUI offender with a BAC below 0.15%, you will not be required to have an IID installed. If your test was at or above 0.15% or if a minor was in the vehicle at the time of the incident, you will be sentenced to having an IID installed in your vehicle for a minimum of six months. If you are a second offender with a BAC below 0.15%, you will have to have an IID for a minimum of one year. If you are a second time offender with a BAC above 0.15% or if you had a minor passenger, you will be sentenced to having an IID for two years. A third or subsequent DUI conviction will result in an IID sentence of at least two years.
Price of An Ignition Interlock Device
If an IID is part of your sentence after being convicted or pleading guilty to a DUI, you will be responsible for all costs associated with the installation and maintenance of the device for the duration of its time in your vehicle. One-time fees for installation and procuring of the device total $87. You will also be required to pay $72.50 each month for calibration and monitoring as well as a $100 refundable deposit, or a $5 monthly charge.
