He transformed a tense situation into something more manageable. He provides thorough explanations about the device and how to use it correctly. I would certainly suggest this place. They are efficient and it's conveniently located.

How does an Interlock Device work?
When you blow into your Ignition Interlock Device, you're providing a breath test sample in order to start the vehicle.

Breathalyzers only measure your Breath Alcohol Concentration (BrAC).
Is an Ignition Interlock the same as a breathalyzer?

A handheld breathalyzer only detects alcohol and may tell you the concentration.
Can I unplug my Ignition Interlock?

Can someone else drive my car?
Yes, but whoever is driving the vehicle MUST take a breath test and pass before driving. Any failed test will still be your responsibility.
