An ignition interlock device (IID) is an instrument installed in your vehicle to test if you have alcohol in your system. The device is connected to your ignition and has an apparatus that you must blow into before you can start your car. If the IID does not detect any alcohol in your system, your car will start. However, if any amount of alcohol is detected, your vehicle will not start.
To ensure you have not consumed alcohol from the time you successfully started your car until you reach your destination, you will be required to blow into the machine periodically throughout your drive. If you fail the breath test during the periodic check, the machine will log the result, which will be sent to the court, resulting in a driver’s license suspension.
When Does an IID Need to Be Installed?
In some circumstances, it is at the judge’s discretion whether or not you must install an IID in your vehicle; in others, an IID installation is required.
A judge might order you to install the device if:
- This is your first DUI offense
- You refused to submit to a breath or chemical test
- This is your first offense with a blood alcohol concentration of .08% or more
- You were caught driving with a license that was suspended for DUI
A judge will require you to install the device if:
- You have multiple DUI convictions
- You caused injury while driving under the influence
How Do I Get an IID Installed?
If you are ordered to have an IID, you must have the device put in by an authorized installer. After it is installed, you must provide proof to the court. If you fail to have an IID set up, your license could be suspended until you meet the requirements of your court order.
How Long Will an IID Need to Be Installed on My Vehicle?
The length of time you are required to have an IID on your vehicle depends on whether you have multiple DUI convictions.
Generally, the time requirements are as follows:
- 6 months for a first DUI offense
- 1 year for a second DUI offense
- 2 years for a third DUI offense
- 3 years for a fourth, and subsequent, DUI offenses
