Ignition interlock devices (IIDs) have become a critical tool in the fight against drunk driving over the past 15 years. These devices, which resemble breathalyzers, are installed directly into a vehicle’s ignition system to prevent drivers with a history of DUIs or suspended licenses from starting their cars if their blood alcohol concentration (BAC) is above the legal limit.
Before a vehicle can be started, the driver must blow into a mouthpiece connected to the device. If the BAC is below the threshold, the car starts normally. However, if it exceeds the limit, the vehicle remains locked until the driver provides a valid sample. Some models also require “rolling retests†during the drive to ensure that no one else provided the initial breath sample. While these tests don’t stop the car immediately, they are recorded and reported to the DMV, helping to monitor compliance.
As of 2020, all U.S. states have implemented laws requiring IIDs for certain drunk driving offenses. New Mexico was the first state to introduce this measure in 2005, and since then, many others have followed. The impact has been significant—New Mexico saw a dramatic drop in drunk driving incidents, with over 70,000 cases prevented between 2006 and 2017. This success prompted other states to adopt similar policies, with some requiring IIDs only for repeat offenders, while others, like Connecticut, mandate them even for first-time DUI offenders.
Research from the Centers for Disease Control and Prevention (CDC) shows that IIDs can reduce DUI offenses by up to 70%. Similarly, Mothers Against Drunk Driving (MADD) found that IIDs cut repeat DUI offenses by 67% and reduced drunk driving-related fatalities by 15%. These findings highlight the effectiveness of IIDs as a consistent and reliable method to keep impaired drivers off the road.
In some states, IIDs are required to obtain a hardship license, which allows limited driving privileges for individuals with a DUI. This typically includes travel to work, school, or medical appointments. In Connecticut, for example, IIDs are not just for DUI offenders but also for those who failed a chemical test, were under the influence of drugs, or were involved in vehicular assault or manslaughter.
Massachusetts’ Melanie’s Law, enacted in 2005, exemplifies stricter penalties for drunk driving. It introduced an IID program for repeat offenders and strengthened license suspension and revocation procedures. In Connecticut, once a driver completes their suspension period and meets all requirements, they can regain their license—but only if they install and maintain an IID for a set period.
IIDs also collect valuable data about the driver, including the number of attempts to start the vehicle and whether rolling retests are passed. Some models include GPS tracking and cameras to confirm that the driver themselves is providing the breath sample. This information is sent to the DMV during regular maintenance checks, which are required every 30 to 90 days. During these visits, technicians inspect the device for tampering and ensure it's functioning properly.
Failure to comply with maintenance schedules can result in the termination of IID privileges, leading to the reinstatement of the license suspension. For anyone facing this requirement, it's important to stay on top of the process. After completing all necessary DMV paperwork, consider reaching out to a trusted service provider like DaSilva’s Auto Body to schedule an appointment and get your IID installed.
