Summary
Intoxalock ignition interlock devices are commonly required after a DUI or DWI offense, but many drivers don’t fully understand what they are, how they work, or how to handle the installation and maintenance process. Whether you’re mandated to install one or you’re researching on behalf of a loved one, this guide will walk you through all the essential details, including cost, function, legal requirements, and common concerns.
What Is an Intoxalock Ignition Interlock Device?
An Intoxalock ignition interlock is a breathalyzer device installed in a vehicle to prevent the car from starting if the driver has been drinking alcohol. It’s part of many state-mandated programs for individuals convicted of driving under the influence (DUI) or driving while intoxicated (DWI).
The device is designed to detect alcohol on a user’s breath. If the measured blood alcohol content (BAC) is above the legal threshold, the vehicle will not start. This helps prevent repeat offenses and ensures safer roads for everyone.
How the Intoxalock Ignition Interlock Works
The Intoxalock ignition interlock functions through a simple, yet secure process:
- Blow Test Before Starting: Before starting your vehicle, you must blow into the device.
- Analysis: The device analyzes your breath for alcohol content.
- Pass or Fail: If your BAC is below the set limit (usually 0.02%), the car starts. If not, the vehicle remains locked.
- Rolling Retests: Periodically during your drive, the device may prompt you for a retest to ensure continued sobriety.
- Data Recording: Every test result, including any failed attempts or tampering, is logged and reported to your monitoring authority.
This ensures both compliance with legal requirements and real-time accountability.
Who Needs an Intoxalock Ignition Interlock?
Courts or state Departments of Motor Vehicles (DMVs) typically require the installation of an Intoxalock ignition interlock device for:
- First-time DUI/DWI offenders in many states
- Repeat DUI offenders
- Individuals with a BAC significantly over the legal limit
- Drivers who refuse a breathalyzer test at a traffic stop
- Those who wish to reinstate their driving privileges during a license suspension period
Some states even mandate the device as a preventive measure in DUI diversion programs.
Legal Requirements by State
Each U.S. state has its own laws and regulations regarding ignition interlock devices. While some require devices only after repeat offenses, others mandate it after the first DUI. The duration of the requirement, monitoring authority, and calibration schedule also vary.
You can visit your state’s DMV website or consult your attorney to verify:
- Whether you’re required to install an Intoxalock
- How long the device must remain installed
- The reporting schedule and compliance requirements
Intoxalock also offers a state-by-state guide on its website to help you determine your specific obligations.

What Happens If You Fail a Breath Test?
Failing a test on your Intoxalock ignition interlock device can have serious consequences:
