How does an IID work?
Have you or someone you know been ordered to install and use an ignition interlock device in New York? This can frequently be a requirement for drivers who are accused of driving under the influence to either retain or regain their driving privileges. But, just how does an IID work?
As explained by Intoxalock, an ignition interlock device provider, there are two primary components of an IID. One is a breath test unit that is able to be held in one hand. This unit is physically connected to your vehicle and communicates with the other primary piece which is a microchip that controls your ignition. When you want to go somewhere, you will need to take a breath test by submitting a breath sample into the handheld unit.
This measures for the presence of alcohol in your breath and sends the results to the microchip. If you pass the test, the chip then releases the lock on your ignition so that you can start your car. If you do not pass the test, the chip keeps your ignition locked, preventing you from starting it until you pass a subsequent test. While you are driving, you will also need to take additional tests at random times when signalled by the IID unit.
This information is not intended to provide legal advice but is instead meant to give people in New York an idea of how ignition interlock devices actually work in the event that they should ever be required to install and use them.
