Florida Ignition Interlock Device Explained

If you are convicted of DUI in Florida, you may be required to install an ignition interlock device (IID) on your car. If you have an ignition interlock device on your car, you will have to blow into the device before you are able to start your car’s ignition. If the device detects alcohol on your breath, you will be unable to start your car. Additionally, while you are driving, you will be required to give breath samples periodically. If alcohol is detected on your breath, your car will become inoperable.

Florida DUI Law and the Ignition Interlock Device (IID)

Under Florida law, you can be required to install an ignition interlock device (IID) on your car even for a first-offense DUI. If your blood alcohol content (BAC) is 0.15% or higher, you will be required to install an ignition interlock device on your car for six months even if this is your first-offense DUI. For a second-offense DUI, if your blood alcohol content is under 0.15%, you will be required to install an ignition interlock device on your car for at least one year. Additionally, for a second-offense DUI, if your blood alcohol content is 0.15% or higher, you will be required to install an ignition interlock device on your car for at least two years. For third and subsequent DUI offenses, you will be required to install an ignition interlock device on your car for at least two years.

The Cost and Care of an Ignition Interlock Device (IID)

If you are ordered to install an ignition interlock device on your car, you are responsible for both the cost and the care of the device while you are serving out your DUI sentence. During this time, the status of your driver’s license will be marked with a “P” to indicate that you are required to have an ignition interlock device installed on your car. If you are caught driving without an ignition interlock device installed on your car, you could be faced with an additional criminal charge. In addition to a non-refundable deposit and installation fee, you will be required to pay a monthly fee for your ignition interlock device until you have completed your DUI sentence.
