First-Time DUI? Here’s What to Expect with an Interlock Device:

If you’ve recently been charged with a DUI, you’re not alone—and you’re not without support. The legal process can feel overwhelming, especially if this is your first offense. One of the most common requirements for getting your driving privileges back is installing an ignition interlock device (IID).

But what exactly is an interlock device, how does it work, and what does the process look like? Let’s break it down.

At RoadGuard Interlock, we believe in second chances. We’re here to guide you through every step—helping you get back on the road safely, quickly, and confidently.

What Is an Ignition Interlock Device (IID)?

An ignition interlock device is essentially a breathalyzer for your car. Before the engine starts, you’ll be required to blow into the device. If your breath alcohol concentration (BrAC) is below the pre-set legal limit, the car will start. If not, you’ll need to wait before trying again. Note that any test you take, whether pass or fail, will be reported to your monitoring authority.

These devices are typically court-mandated for drivers convicted of a DUI, especially those seeking to reinstate their license through a restricted or hardship program. IIDs are used to help promote safe driving while allowing individuals to regain their independence.

Step-by-Step: What to Expect

1. Understand Your Court Requirements

Each state has specific laws and timeframes when it comes to ignition interlock compliance. Even first-time DUI offenders are often required to install a device. Your court documents or DMV instructions will clarify how long you’ll need the device installed and what steps you must take to comply.

4. Routine Maintenance and Calibration

Your IID will need monthly service checks to ensure it’s working properly and remains compliant with your state’s regulations. We’ll remind you when it’s time to come in, and our large service center network makes it easy to stay on schedule.

Will It Affect My Driving?

Not at all. Once you provide your initial breath sample and the car starts, you drive as normal. In some cases, you may be asked to take a rolling retest, which is designed to be safe and non-distracting while driving.

How Long Will I Need the Device?

For first-time DUI cases, IID installation terms typically range from 3 months to a year. The length depends on your state laws, your blood alcohol level at the time of arrest, and whether any aggravating factors were involved. Your court or DMV will provide the exact timeframe.
