Frequently Asked Questions

Once the device is installed, drivers blow into the car breathalyzer mouthpiece to provide a breath sample. The device tests for breath alcohol content (BrAC) within the legal limit. If it's under the limit (typically .02), then the driver can put their keys in the ignition and start the car.
An ignition interlock device, also frequently referred to as a car breathalyzer, ranges in cost between $70 and $150 for installation.
