Answers about IIDs for Colorado DUIs

Q: When would someone have to have an IID for a first-time DUI in Colorado?

A: In general, a first-time DUI conviction in Colorado will be associated with an IID requirement when a motorist has:

  • Refused BAC testing during the DUI stop
  • Been found to have a BAC at or above 0.15.

In both of these situations, the IID will typically be required for 2 years, and motorists will be required to install and maintain an IID on all of their vehicles.

Q: When else would IIDs be required?

A: Subsequent BAC test refusals (in DUI stops), as well as any subsequent DUI conviction, will usually result in an IID requirement.

Q: How much ignition interlock devices cost and who pays for them?

A: Motorists ordered to install IIDs on their vehicles will have to cover the costs of these devices, which:

  • Vary from provider to provider
  • Include both the costs of installing the device, as well as maintaining/recalibrating it every 60 to 90 days – While installation costs tend to range from about $75 to $150, maintenance fees typically range from around $50 to $100.

Financial assistance may be available for those who qualify, and the Colorado DMV has further information about this assistance.1

Q: What happens if I don’t comply with the IID requirements?

A: Failing to comply with the ignition interlock device requirement for a DUI can result in:

  • A violation of your DUI probation
  • An extension of your IID requirement
  • Possibly additional fines (and/or other penalties).

Common examples of failing to comply with the IID requirement include (but are not limited to):

  • Failing to install an IID on all vehicles driven by a motorist
  • Trying to circumvent the IID by driving someone else’s vehicle
  • Getting someone else to blow into the IID
  • Trying to disable the IID
  • Submitting breath samples to the IID that are positive for alcohol – Three of these samples within a 12-month period can trigger an automatic extension of the IID requirement (if not other penalties).

Q: Where can I get an IID installed?

A: In Colorado, four companies are currently approved to provide IID services for people dealing with DUI cases and penalties. These companies include:

  • #1 A LifeSaver of CO
  • 1A Smart Start, Inc.
  • Guardian
  • Intoxalock.
