Unless you’ve been arrested for DWI (Driving While Intoxicated) or aren’t familiar with drunk driving laws, then it’s likely that you’ve never heard of an Ignition Interlock Device (IID). The following information may be of importance to you if f you, or someone you know, has recently been convicted or is currently facing drunk driving charges, 

What is an Ignition Interlock Device (IID)?

An Ignition Interlock Device (IID) is a small breathalyzer about the size of a regular TV remote control or mobile phone. If you were convicted of DWI/DUI on or after August 15th, 2010 then you will have been required to have one installed on every vehicle you own or use.  You’re then required to blow into the device before the engine will even start.

How Does it Work?

An Ignition Interlock Device measures your Breath Alcohol Content (BrAC), and if your alcohol level is over the state limit, you will not be able to use your vehicle. This ensures that you’re alcohol-free before you can drive.

The device does random/rolling/running retests at random intervals during your drive to ensure that you remain alcohol-free while you’re driving. The device will beep when it’s time for a retest and you will have to pull over and park on the side of the road to provide a sample.

Some states require you to install a camera alongside the IID in case someone other than the owner of the vehicle drives the car while intoxicated, the violation will be caught on video.

Do I Need an Ignition Interlock Device (IID)?

If you have been convicted of DUI/DWI in the state of New York, then an IID is unavoidable. These devices are mandatory if you’re a first-time offender and your reckless driving caused injury to another party. They may even be required if you have multiple drunk driving convictions and are trying to get your driver’s license back after having it revoked.


Some states require an IID for first-time DUI/DWI offenders who recorded a BAC higher than .15%, but not New York.


How Long Am I Required to Use an Ignition Interlock Device (IID)?

Every state has its own laws regarding how long a driver is required to use the IID, with most cases depending on the severity of the offense. If you’ve been convicted for drunk driving in the state of New York on or after August 15th, 2010 and an IID is ordered by the court, the device will need to be installed on each vehicle you own or operate and remain there for at least twelve (12) months, unless otherwise ordered by the court.
