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. This fee is a one-time fee paid at the start of your lease period for the device to be installed into your vehicle. This fee is paid directly to the service center for the work done to complete your installation.
At your appointment, you will learn how to use the Intoxalock ignition interlock device, what to avoid before blowing into the device, and how to maintain the device. Tutorial videos are also available on the Intoxalock mobile app.
