If you’ve recently been ordered to install an ignition interlock device (IID), you’re not alone. Thousands of individuals across the country go through this every year, but finding the right provider shouldn’t add stress to the process. This guide shows you exactly what to look for when searching for an interlock provider near you so you can regain your license quickly and confidently.


What Is an Ignition Interlock Device?

An IID is a breathalyzer installed directly into your vehicle’s ignition system. Before starting the car, you must blow into the mouthpiece; if your blood alcohol concentration (BrAC) is below the legal limit, the vehicle starts. If it’s above the threshold, the car won’t start—acting as a legal safeguard and accountability tool. Learn more on our Ignition Interlock Device FAQ page.

These devices are court-mandated in many states following a DUI. Choosing a compliant, certified provider helps you stay within legal requirements and avoid future fines or complications.


What to Look For in a Provider

  1. Local Service Availability
    Opt for a provider with nearby service centers for installation and monthly calibration appointments. You can search “interlock device near me” or use our Locations tool to find a service center in your area.
  2. Fast Scheduling
    Avoid providers that book weeks out. RoadGuard offers same-day and next-day installation in many locations, making it easier to meet court deadlines.
  3. Transparent Pricing
    It’s important to choose a provider who’s upfront about fees. Watch out for hidden charges around calibration, service appointments, or device removal. Clear, honest pricing is non-negotiable. We break down all costs clearly for you.

Frequently Asked Questions

Q: How does an interlock device work?
When you start your vehicle, you have to blow into a mouthpiece that’s connected to the ignition interlock device, sometimes called a car breathalyzer. The device will then measure your breath alcohol concentration (BrAC) and determine whether your BrAC is low enough to allow the car to start.

Q: What do I need to bring to my ignition interlock installation appointment?
A valid photo ID (Driver’s license, Military ID, or Passport). Your vehicle registration. Any documents about your case (court order), and a form of payment. Note: if your driving privileges have been revoked, you will need someone to drive your car to your appointment.

Q: How long do I need to keep the device installed?
This varies by state and situation. Learn more on our FAQ page.
