What is an Intoxalock ignition interlock
An 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
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.

Step by step instructions
To use your ignition interlock device, press the button on the handheld
unit and wait until the LED displays “Blow.” Most states require you to
submit a blow, inhale, blow breath pattern into the mouthpiece. Some states
require you to just blow into the device. Check your User’s
Manual for detailed instructions.
All states require mandated retests to be submitted while the vehicle is
running. The interlock device will ask for a retest at randomly spaced time
intervals with a loud beep and a message displayed on the LED screen of the
handheld. The user must submit another breath sample each time a retest is
requested. If alcohol is detected during a retest, your ignition interlock
will not turn off your vehicle while it is in motion but it will give a
signal for you to stop.
