Discover what Ignition Interlock Devices (IIDs) are, how they work, and when they are required. Learn more about the legal requirements and situations where an IID may be necessary.

If you have been involved in a DUI (Driving Under the Influence) offense, you may have heard the term “Ignition Interlock Device” or IID. This device plays a significant role in ensuring road safety by preventing individuals from driving under the influence of alcohol. In this blog, we will explore what Ignition Interlock Devices are, how they function, and when they are required by law.

What is an Ignition Interlock Device?

An Ignition Interlock Device (IID) is a breathalyzer connected to a vehicle’s ignition system. It requires the driver to blow into the device before starting the vehicle. If the device detects alcohol above a specified limit, typically 0.02% BAC (Blood Alcohol Concentration), the car will not start. The IID is designed to prevent individuals convicted of DUI offenses from driving while intoxicated.

These devices are often used as a tool for rehabilitation and compliance with court-ordered terms, helping to reduce repeat offenses and promoting safer driving.

How Do Ignition Interlock Devices Work?

The process is relatively simple. Before starting the vehicle, the driver must blow into the IID. The device will analyze the sample for alcohol content. If the reading is below the allowable BAC threshold, the vehicle starts as usual. However, if the reading exceeds the limit, the vehicle will remain inoperable.

In addition to this initial breath sample, many IIDs require periodic breath tests while driving. These random “rolling tests” are to ensure the driver remains sober throughout the journey. If the driver fails the test or attempts to tamper with the device, the IID will trigger an alert, notifying the authorities.

When Are Ignition Interlock Devices Required?

Ignition Interlock Devices are typically required in the following situations:

  1. DUI Convictions: A common requirement for individuals convicted of DUI or DWI offenses. In many states, a court will mandate the installation of an IID as part of the sentencing for a DUI charge, particularly if it’s a repeat offense.
  2. Probation Terms: For those serving probation after a DUI conviction, IIDs may be installed to ensure they comply with sobriety requirements.
  3. License Reinstatement: In some cases, drivers who have had their licenses suspended or revoked due to alcohol-related offenses must install an IID in their vehicles to regain driving privileges.
  4. First-Time Offenders with High BAC Levels: While first-time DUI offenders may not always be required to install an IID, those with a particularly high BAC may be mandated to do so.
  5. Certain States and Circumstances: Some states have laws that automatically require IIDs for individuals convicted of a DUI offense, while others may consider factors like prior DUI history, BAC levels, or whether an accident occurred during the offense.

Why Are Ignition Interlock Devices Important?

IIDs play a crucial role in reducing drunk driving incidents and promoting public safety. By requiring drivers to prove their sobriety before operating their vehicle, IIDs help to deter repeat offenses and save lives. They act as a powerful tool in rehabilitation, encouraging offenders to remain sober and responsible behind the wheel.
