Colorado Ignition Interlock Device (IID) Requirements

DR 2643, the Affidavit of Enrollment for Level II Drug and Alcohol Education and Treatment, serves as a provisional "pass" for the Colorado DMV.

Ignition Interlock Device (IID) Requirements in Colorado

Colorado utilizes Ignition Interlock Devices (IIDs) as a key component in its strategy to reduce drunk driving. If your license is revoked due to a DUI or DWAI in Colorado, you will likely be required to install an IID in your vehicle as a condition of license reinstatement. This requirement applies to various DUI-related offenses.

When is an IID Required in Colorado?

An IID is generally required in Colorado for the following offenses:

• DUI (Driving Under the Influence): BAC of 0.08% or higher.
• DWAI (Driving While Ability Impaired): BAC of 0.05% to 0.08%.
• Refusal to Submit to Chemical Testing: Refusing a breath or blood test results in an automatic IID requirement. The "Refusal" triggers a Persistent Drunk Driver (PDD) designation.
• Persistent Drunk Driver (PDD): Designated as a PDD due to high BAC (0.15 or higher) or refusal to submit to chemical testing, leading to a mandatory IID requirement.
• Multiple DUI/DWAI Offenses: Repeat offenders face extended IID requirements.
• Express Consent Revocation: If a driver refuses a test or tests ≥ 0.08, the DMV revokes the license administratively via the "Express Consent" statute. To reinstate driving privileges early (using an Interlock device), the driver must enroll in Level II Education/Therapy immediately.
• Reinstatement after Revocation: To reinstate driving privileges early after an Express Consent revocation, enrollment in Level II Education/Therapy is required, which often necessitates the installation of an IID.

Duration of IID Requirement in Colorado

The length of time you are required to have an IID installed depends on the specific circumstances of your case, including the number of prior offenses and your BAC level.

• First DUI Offense (BAC below 0.15 and no refusal): At least eight months and up to two years.
• First DUI Offense (BAC of 0.15 or higher or refusal): One to two years.
• Second or Subsequent DUI Offense: Two to five years.
• Persistent Drunk Driver (PDD): Two years minimum, with potential for longer periods.
• License Reinstatement After Revocation: Even if not sentenced by the court, an IID is often required to reinstate your license after a revocation period due to DUI/DWAI.

How the Colorado IID Works

• Installation: After a DUI conviction, you must visit a Colorado-approved IID vendor to install the device.
• Breath Tests: Before starting your vehicle, you will be required to submit a breath sample into the IID. The device analyzes your breath for alcohol content.
• Starting the Vehicle: If the IID detects alcohol above the pre-set limit (typically 0.02%), the vehicle will not start.
• Rolling Retests: While driving, the IID will prompt you for random "rolling retests." You must provide a breath sample while operating the vehicle. Failing to do so or providing a sample with alcohol above the limit will trigger a violation.
• Data Recording: The IID records all breath tests, including dates, times, and alcohol levels. This data is regularly transmitted to the Colorado DMV and can be accessed by the court or probation officer.
• Calibration and Maintenance: IIDs require regular calibration and maintenance, typically every 30 to 60 days. These appointments are essential to ensure the device's accuracy and proper functioning.

Costs Associated with IID in Colorado

The costs of an IID in Colorado can be substantial and are the responsibility of the offender. These costs include:

• Installation Fee: Typically ranges from $75 to $150.
• Monthly Lease/Rental Fee: Approximately $70 to $100 per month.
• Calibration Fee: $50 to $75 per calibration (usually monthly or bi-monthly).
• Removal Fee: Approximately $50 to $100.

These costs can add up quickly, making it crucial to factor them into your budget.

State-Approved IID Providers in Colorado

To ensure compliance, you must use an IID provider approved by the Colorado Department of Revenue. The Colorado DMV maintains a list of approved vendors on its website.

IID Violations in Colorado: What Happens?

Violating the terms of your IID restriction can lead to serious consequences:

• Failed Breath Tests: Providing a breath sample with an alcohol content above the limit.
• Missed Rolling Retests: Failing to provide a breath sample during a rolling retest.
• Tampering with the Device: Attempting to disconnect, bypass, or otherwise tamper with the IID.
• Circumventing the Device: Starting the vehicle by any means other than using your own breath sample.
• Missed Calibration Appointments: Failing to attend scheduled calibration and maintenance appointments.

Consequences of IID violations can include:

• Extension of IID Requirement: The period you are required to have the IID may be extended.
• License Suspension or Revocation: Your driver's license may be suspended or revoked.
• Probation Violation: If you are on probation, an IID violation can lead to a probation revocation hearing and potential jail time.
• Vehicle Impoundment: In some cases, your vehicle may be impounded.

To reinstate driving privileges early, using an Interlock device, the driver must enroll in Level II Education/Therapy immediately, often weeks or months before their court date.
