If you have a drunk driving conviction and are now facing an ignition interlock device requirement, chances are you have a lot of questions. In the infographic below, Interlock Device of New Jersey https://interlockdevice.com/ breaks down the basics to help ease your mind during this stressful time.
What Is An Ignition Interlock Device?
Ignition interlock devices (IIDs) were first invented in the 1970s to prevent people from operating a vehicle while they are intoxicated. They have been steadily growing in popularity over the decades, and now all 50 states have some form of an interlock law that requires DUI offenders to have an ignition interlock device installed on any vehicle they drive so that they may maintain their driving privileges.
Interlock devices are hard-wired to a person’s vehicle and are connected directly to the car’s starter. These devices are slightly larger than a cell phone and are completely unobtrusive. In order to start the car, the driver will simply need to first blow into the device in order for the breathalyzer test to take place.
How Does An Ignition Interlock Device Work?
At the most basic level, an ignition interlock device works by requiring a breath sample before a car can start. Since the device is installed to interrupt the ignition system, it won’t allow the car to start until a passing breath test can be provided.
Once the driver provides a breath sample, the device will analyze the blood alcohol content. If it is determined that the BAC is over the limit preset by the state, the car will not be able to start. The device will then “time out” for a set period of time before the test can be retaken.
Ignition interlock devices are also commonly set up to administer “rolling tests” which are designed to prevent a sober friend from starting the car. These retests will take place at sporadic intervals while on the road and will require the driver to pull over for safety before providing the sample. It is important to note, that for safety purposes, that while an interlock device can prevent a car from starting, it cannot shut off an engine that is already running.
