If you use an ignition interlock, sooner or later you’re going to encounter an Abort Test. You’ll blow into your device and the Abort light will flash. Your vehicle won’t start.
In fact, aborts are nothing to worry about. Human lungs are different, and in fact, it’s impossible for every single breath to be uniform. Sometimes your breath test won’t give the device exactly what it needs, so the “abort” signal lets you know that. You might have blown too hard, too long, or too softly. Or you might have forgotten to hum. It happens.
An abort is not a fail. It will not count against you, or get you locked out of your vehicle. You are not in violation of the law. All you need to do is blow a proper breath test and you’ll be fine. Usually there is a short waiting interval – a minute or less – before you can blow again.
Some devices, such as the LifeSafer FC-200, will let you know the reason for your aborted test. The screen will tell you to “blow shorter” or “blow harder.”
When you first get your ignition interlock, it is likely that you’ll have a few aborted tests. But before long, the breath test will become second nature, and you’ll pass it and fire up the engine every time.
