Ignition Interlock Device Information

OvervieW

An ignition interlock device (IID) is a breathalyzer installed in a vehicle that requires the driver to blow into it before starting the engine and periodically while driving. The device ensures that the driver has a zero percent alcohol concentration before the vehicle can be operated.

The IID is typically installed near the driver’s seat and is directly connected to the vehicle’s ignition system. This device is mandatory for individuals convicted of a DUI as ordered by the court or the Motor Vehicle Department (MVD).

How to Install an Ignition Interlock Device

To install an IID, you must contact a state-certified agency. Certified agency locations are available throughout the state, and you will need to:

  • Select a location convenient to your home or workplace.
  • Contact the agency to schedule an installation appointment.
  • Keep in mind that regular maintenance and calibration of the device are required.

Ongoing Maintenance & Compliance

Periodic maintenance and calibration must be performed by the certified agency. Maintenance reports must be submitted to the Court or MVD as required by law. Choosing a nearby agency is recommended for ease of access to required servicing.

Choosing a Certified IID Provider

When selecting an IID provider, consider the following factors:

  • Reputation – Look for an agency with positive reviews and a solid track record.
  • Location – Choose a provider conveniently located for installation and maintenance.
  • Technology – Ensure the device is reliable and meets state compliance standards.
  • Pricing – Costs vary by provider; compare pricing and service packages.

Duration of Ignition Interlock Requirement

The length of time you must have an IID installed depends on your court order and MVD requirements.

  • Standard Requirement: Typically, the IID must remain installed for 12 months.
  • Extended Requirement: MVD may extend the required duration based on the specifics of your conviction.
  • Early Removal Eligibility: If you are convicted of a first-time, non-aggravated DUI, you may qualify for early removal after 6 months, provided you have no violations.

To confirm the exact duration of your IID requirement, contact your local MVD or consult with your legal counsel.
