Installing an ignition interlock device with us is very quick and convenient. You may ask: How does an interlock device work? The simple answer: When you blow into your ignition interlock device, you’re providing a breath test sample to start the vehicle. This post will further explain this topic.
How does an interlock device work?
When you blow into your ignition interlock device, you’re providing a breath test sample to start the vehicle. The device will measure your breath alcohol concentration (BrAC) and will either say that you passed, need to retest, or failed.
“And that’s it once I start the vehicle?”
That’s it to start the vehicle. You will also be asked to take rolling retests throughout your drive. This helps to prevent the driver from drinking alcohol after the initial test.
For most of our clients, an ignition interlock device makes a beeping noise to prompt for random rolling retests. Since a beep or other noise could be missed by someone who is deaf or hard of hearing, Smart Start of Louisiana can add an external LED light for our deaf or hard of hearing clients.
“Will I receive training on how to use my interlock device?”
Yes, absolutely. We won’t let you leave your installation appointment until we know you’re comfortable using your device. It doesn’t take most people long to learn.
