Ignition Interlock Devices Explained by a Denver Criminal Lawyer

November 30, 2016

After a DUI administrative license revocation or DUI conviction, the DMV in Colorado is obligated to try to ensure you never get behind the wheel while over the limit again. One way to stop at-risk drivers is with the help of an ignition interlock device, or IID. What exactly are these devices and when are you required to use them? A Denver criminal lawyer explains what you need to know:


What is an Ignition Interlock Device (IID)?

These devices are installed on vehicles to prevent the driver from being able to start the car if he or she is under the influence. In order to start the vehicle, the driver must blow into the device. If you have been drinking alcohol, the device will detect it on your breath and not allow you to start the vehicle. However, if you have not been drinking, the car will start. The device may prompt you to retest while the car is in motion to ensure you are not drinking while behind the wheel.


When will you be required to use an Ignition Interlock Device?

Colorado law states you may be required to use one of these devices after you are convicted for a DUI or if the DMV administratively revokes your license. If it is your first DUI, you may be required to use the device for anywhere between 4 months to 2 years. If you have more than two prior convictions, you will likely have to use the device for 2 years.


While it is your right to deny a roadside breathalizer test, in Colorado, you may also be required to use the device if you have refused to take the more official chemical test after being pulled over by a law enforcement officer.


What happens if you don’t use the IID device?

If the court orders you to install an ignition interlock device, one must be placed on every vehicle you intend to drive. If you choose to drive a vehicle without a device or try to drive the vehicle without submitting to the device’s breath test, your license may be revoked for up to one year. For example, if the court finds out you had a friend blow into the device to bypass the test and then you drive the vehicle home this is grounds for a license revocation.


If you are required to use the IID device you are also responsible for getting it  serviced every sixty days. If the court finds out you have not had the device serviced, your license will be suspended until you comply with the guidelines.

Are there consequences for failing an ignition interlock breath test?

Drivers who continuously fail the breath test administered by the ignition interlock device will face additional consequences. These consequences can include a license suspension or extended time with the device installed on your vehicle.
