If you are convicted of driving under the influence of alcohol, it’s possible you could be required to install an ignition interlock device (IID) in your vehicle.

This device is installed to prevent you from operating your vehicle if there is any alcohol in your system.

How does it work?

You’re required to blow into the IID every time you want to start your car. If there is no alcohol in your system, your vehicle will start, and you can go about your business.

Conversely, if it’s found that your breath contains alcohol, the ignition is disabled.

Will you need to install an IID after a DUI?

You never have to worry about the installation of an ignition interlock device if you avoid driving drunk. However, if you make this mistake and it results in a conviction, it may be required by law. Two of the most common situations leading to the installation of this device include:

• Having a minor in your vehicle at the time of your arrest
• Having more than one drunk driving conviction on your record

If the time comes to install an IID, you’ll be responsible for the cost. In addition to the installation fee, there are fees for such things as calibrating and monitoring the device that also come into play.

If you’re arrested for driving under the influence of alcohol you shouldn’t assume you’ll also be convicted. You need to understand your legal rights as well as the defense strategy you can use to avoid a conviction. This can help you avoid the consequences, which could include the mandatory installation of an ignition interlock device.
