Ignition Interlock Devices Installed Through DMVInterlock
Getting a DUI can be overwhelming, and if you’re required to install an ignition interlock device (IID), you probably have a lot of questions. Understanding what an IID is and how it works can help you feel more prepared for the process.
What Is an Ignition Interlock Device?
An ignition interlock device (IID) is a breathalyzer installed in a vehicle to prevent drunk driving. Before starting the car, the driver must pass a Breath Alcohol Content (BrAC) test. If alcohol is detected above the legal limit, the vehicle won’t start.
Many states require IIDs after a DUI or OWI conviction for license reinstatement. The experience of using an IID can vary widely. A reliable provider with convenient installation locations, responsive customer support, and simple-to-use design can make the process much smoother. In contrast, limited service centers, poor customer assistance, and a complicated user experience can make compliance stressful and frustrating.
