What Exactly Is an Interlock Device?

In some cases, if you have been charged with a DWI, the court may require you to get an interlock device installed in your vehicle. An ignition interlock device, also known as an in-car breathalyzer, connects to your vehicle’s ignition system. In order to start your vehicle, you must first blow into the interlock device, the device temporarily prevents the vehicle from starting if the driver’s breath alcohol concentration (BrAC) exceeds the preset level.

In most cases, you will not need to use this device forever. It is usually temporary, and once you gain good standing with the court and meet all requirements, the interlock device can be removed from your vehicle. While the devices can be an annoyance, try to look at the situation positively. For example, you are still legally able to drive your vehicle, and your license was not suspended. With some good driving under your belt, you should be able to return the interlock device in a matter of time.
