How Long Do I Have To Drive With An Interlock Device, After My Conviction?

It is fairly common for states to require installation of an ignition interlock device, commonly referred to as an IID. The IID removes temptation as it requires a driver to perform a Breathalyzer test before driving, and prevents a vehicle from being started if the Breathalyzer detects an alcohol level above the legal limit. If you’ve been convicted of a DUI you will more than likely have to install an IID and how long you are required to use it will depend on various factors.

First time DUI offenders are typically required to keep their IID installed for a minimum of 5 months. And the law mandates that these devices be calibrated every 60 days, so you’ll have to remember to take your vehicle in for this calibration. If your device is not calibrated properly due to your negligence, skipping the appointments, etc. then your license could be suspended.

Second time offenders are required to keep their IID installed for a full year. And missing three calibration appointments will result in license suspension.
Third time offenders are required to keep their IID installed for two full years.
And fourth time offenders are required to keep their IID installed for three full years.

While the IID system may seem like a hassle, it’s really best to see it as a great way to ensure that you retain your driving privileges, as it will prevent you from making a poor choice. Drunk driving is a potentially deadly activity, and an IID will ensure that you and other motorists are safe, while also allowing you to get to your meetings, counseling, and your job.
