What is an IID?

An ignition interlock device, or IID, is sometimes called a car breathalyzer. The devices are wired into a vehicle’s ignition system. Once installed, an IID will require the driver to take and pass a Breath Alcohol Concentration (BrAC) test before they can start the car. The device will also request random retests during most trips to prevent tampering and ensure that the driver remains sober.

If IID installation is mandated by the court following an alcohol-based driving offense, then all testing results will be shared with the state’s monitoring authority. Interlocks are often a requirement for regaining driving privileges following an offense. Devices are available on a voluntary basis to anyone who wants to install one as well.

How Do I Know If I Need An IID?

If you are required to install an ignition interlock device following an offense, this will be made clear to you by the Motor Vehicle Administration (MVA), a court, or an Administrative Law Judge. Typically, state law will dictate the interlock term, so you can often find this information on the Maryland MVA's official website. If you are at all unsure that you need an interlock, check with your attorney or the MVA, who should be able to assist.

How Much Will My Offense Cost?

There are many costs associated with a conviction for DUI or a similar offense. They include increased insurance rates, possible lost wages, fines, and transportation expenses if your driver’s license is revoked. If you are required to install an IID, you will be responsible for installation and monthly leasing fees. Overall, the variety of costs associated with a DUI can total several thousand dollars.

IID lease rates cost a few dollars per day with other required purchases including, but not limited to, installation, activation, calibration, and removal.

How Do I Regain Driving Privileges in Maryland?

Some DUI-convicted drivers are able to regain driving privileges during their suspension period by participating in the state’s Ignition Interlock Program, and some are required to participate based on their offense. In order to qualify for this program, drivers may need to:

Prove their license was not canceled, suspended, or revoked at the time of the offense
Within 30 days of the offense, drivers must surrender their license to the MVA, or if they do not have the license, sign a certified statement that they do not have the license in their possession (for example, if it was confiscated)
Show in writing their intention to participate in the Ignition Interlock Program by completing the appropriate form and returning it to a full-service MVA office (this is for non-commercial drivers only; commercial drivers must downgrade to a standard license to participate)
Pay any applicable fees
Have an IID installed by an approved provider (like Intoxalock 833-259-3046)
Complete any necessary community service, suspension period, and court-ordered treatment
Show proof of appropriate insurance coverage
