The function of an ignition interlock device

On Behalf of | Jul 20, 2023 | DUI |

Drunk driving can come with serious criminal penalties, and it can leave one facing a range of consequences that can include time behind bars, expensive fines and more. Depending on the details of your case, your criminal history and other factors that are unique to your situation, you may be required to install an ignition interlock device (IID) in order to drive again. It may be helpful for you to learn about how these devices work and what to expect if this is a requirement for you.

You install an ignition interlock device directly into a car. This device requires the driver to breathe into it in order for the vehicle to start. It will read the driver’s alcohol content, and if it registers any discernible amount of alcohol from your breath, it will not allow the vehicle to start. Depending on your individual circumstances and prior DWI history, you may need an IID in your vehicle for months or longer.

How does a car breathalyzer work?

These devices are also car breathalyzers because they function similarly to a breathalyzer apparatus that police may use during a suspected drunk driving traffic stop. They are typically small devices, and they can be quite discreet. If you are required to have an IID installed in your car, you will have to pay for professional installation services. In addition to the required test to start the vehicle, the device also requires you to take random tests at unpredictable intervals. You are given enough time to safely pull over and blow into the IID. Even if you fail a retest after the vehicle has started, it will never shut off the ignition but it will be recorded by the device.

It is important that these devices receive regular calibration. It will be your responsibility to understand how to properly use your device, how to get it installed and how often you need to calibrate the device.
