What is an Intoxalock ignition interlock device?

Intoxalock legacy deviceAn ignition interlock device is a breathalyzer that is installed in your vehicle to prevent drinking and driving. It is made up of a mouthpiece, a handheld unit and a cord that attaches to your vehicle’s ignition system. You are required to blow into the mouthpiece to test your Breath Alcohol Concentration (BrAC) before starting your car.

If your BrAC is below the limit set by your state, your vehicle will start. If your BrAC is above your state’s limit, your vehicle will not start until you submit a breath sample that no longer detects alcohol.

All activity is stored in the device and sent to your monitoring department (court, DMV, probation officer, etc.). With real-time reporting capabilities, Intoxalock is able to upload data immediately to our Log Reporter website. Some states require the information to be made available immediately, while others require the data to be sent monthly.
