How Does an Interlock Device Work?

Here's a general overview of how interlock devices work:

  • An interlock device estimates blood alcohol content (BAC) from a breath sample.
  • A vehicle with an interlock device installed won't start unless the driver provides a clean breath sample
  • To use an interlock device, blow through the mouthpiece. The device will indicate when to start and stop blowing. The sensor in the device measures the alcohol level in the deep lungs. This value is converted into the Blood Alcohol Content (BAC) measurement.
  • On occasion, the device will require a new breath sample after the engine starts. If the sample isn't provided or doesn't meet safe blood alcohol content levels, the device logs the event, warns the driver, and starts an alarm until the ignition is turned off or a clean sample is provided.

An ignition interlock device monitors your results and provides proof of safe driving practices while helping to prevent drunk driving.
