What is an Ignition Interlock Device in DUI Cases?

If you are convicted of driving under the influence (DUI) of alcohol or drugs in Colorado, you may be required to install something known as an ignition interlock device (or IID) in your vehicle in order to continue driving. Whether or not a DUI-related conviction will result in the requirement of an ignition interlock device will depend on the circumstances of the case. In the event you are required to install an ignition interlock device, you will be required to pay for the IID and ensure that it is installed by an approved provider. There are also requirements you must follow concerning use of the IID in your vehicle. Our Denver DUI defense lawyers can tell you more.

Understanding Ignition Interlock Devices 

An ignition interlock device is a specific type of device, according to the Colorado Department of Revenue, “that is installed on motor vehicles to prohibit individuals from operating a vehicle while under the influence of alcohol.” If you are required to install an ignition interlock device, the device will “require your breath sample before the engine will start, and you are periodically required to provide breath samples while driving.” If the device detects “an elevated alcohol concentration,” your vehicle will not start.

When a person is required to have an IID, they must have the device installed by one of the approved interlock vendors identified by the Colorado Department of Revenue.

Who is Required to Install an Ignition Interlock Device? 

Whether or not you were previously required to install an IID, or will be required to have one installed, will depend on the specific DUI offense and when it occurred. For offenses resulting in arrests prior to January 1, 2023, a first DUI offense required a one-month wait, after which point a person with a DUI conviction could apply for a restricted license with an IID, and interlock requirement times ranged from 8 months to 2 years. Second and subsequent DUI convictions required a 2-year interlock.

For DUI arrests on or after January 1, 2023, an immediate license reinstatement with an interlock is possible (no more one-month waiting period), with a required interlock period of anywhere from 9 months to 2 years depending on your BAC for a first-time offense. A second or subsequent offense requires a 2-year interlock. If you refuse chemical testing, you will be subjected to an automatic 2-year IID requirement.

There are additional offenses you can face charges for if you attempt to tamper with an IID or to have another person blow into the device to start your vehicle due to your intoxication.
