What you need to know about Ignition Interlock Devices

January 18, 2019

Having an ignition interlock isn’t fun, make no mistake. But knowing what to expect makes life a little bit easier. While most devices are pretty simple to operate, there’s a few things you need to know about your ignition interlock device (IID).


How to get an interlock device. First, check with the court, DMV or whoever the authority requiring the IID is to make sure you are cleared and eligible to get your device installed.  Installing one too soon can lead to unnecessary time and expense.


Next, use the MyDUISolution Marketplace to compare and choose an ignition interlock service provider. The costs of the IID vary by state and provider. You are responsible for all expenses associated with an interlock device and its service. So, be sure to ask what those costs are or could possibly be.


How to use an ignition interlock. Each interlock has a different way to use it and your installer will walk you through how to operate and blow into your device. Also, you’ll want to know what blood-alcohol-concentration (BAC) limit your interlock is set at. Those “set-points” are determined by the State. The ignition interlock measures the alcohol in your system using your breath. If the amount of alcohol detected on your breath exceeds a pre-programmed level, the device will register a ‘fail’ and a temporarily “lockout” will occur. We recommend getting a handheld personal breathalyzer to pre-test yourself. It could help you avoid getting a ‘fail’ on your IID. Once you start the vehicle, the IID will require random retests while it is running. The timing of those retests are also determined by the State.


How your ignition interlock records and reports are used. Every time you use your Interlock, it records many things along with your BAC. It stores the data in the device. Many states require real-time reporting. That means the interlock sends the data to the monitoring authority right when its being used. Other states require the data be downloaded at your calibration appointments then sent to them.


What if someone else drives your car? There is no rule against letting someone else drive your car while you have an ignition interlock installed. If someone else is driving your car, they are also required to use the device. If they violate or fail a test, it is likely to negatively impact you. Another alternative is finding an interlock device that comes with a camera for positive ID. Some providers, like Draeger Interlock offer ignition interlock devices with a camera option available. You’ll want to check with the devices available in your state.
