Ignition Intoxalock Interlock Monitor

Intoxalock makes it easy for you to get back on the road after an alcohol-related driving offense. An IID is a small, handheld breathalyzer for car ignitions that’s installed to prevent users from being able to start their vehicle after drinking alcohol. Sometimes they’re referred to as car breathalyzers, or as a breath alcohol ignition interlock device (BAIID). The ignition interlock device (IID) is easy to use and convenient to install. 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. Intoxalock offers reliable easy-to-use technology, one button activation and simple breath pattern.
