What Is Ignition Interlock?
An ignition interlock device is a breathalyzer for your vehicle.
It requires you to blow into the device before starting your car and helps you
drive safely by not allowing your vehicle to start if you are under the influence of alcohol.
Ignition interlock devices allow you to continue driving legally after getting a DUI.
Many states require ignition interlock devices, or car breathalyzers, as a way to regain your driving privileges after a DUI.
