One post-DWI recidivism deterrent is an ignition interlock device, which may be required for some individuals after a drunk driving arrest. Get the facts about IIDs and how to defend yourself against criminal charges. 

The Basics of Ignition Interlock Devices (IID)  

If someone has been found guilty of driving under the influence of alcohol, they may be required to have an ignition interlock device (IID) installed in their vehicle. This device is a personal breathalyzer that prevents a driver from being able to operate a vehicle if their blood alcohol content (BAC) registers over the legal amount of 0.08%. To successfully start their vehicle or continue driving, they must be able to pass the breathalyzer test. 

When Drivers Need an IID   

Even though many first-time DWIs are resolved without a judge issuing the installation of an IID, it’s possible for this to happen with any drunk driving conviction. Often, an ignition interlock device is ordered by a judge in cases where the defendant has a previous record of driving under the influence, or if their blood alcohol content was excessively over the legal limit. The decision of whether to order an IID is up to the judge who presides over your case, and if they think it will reduce the risk of a repeat offense, they will most likely order it.  

What Happens If You Drive Drunk with an IID?

If you make an attempt to drive your car with a BAC over the legal limit, you won’t be able to start the vehicle. You must pass the breathalyzer test every time you start your car, even if you only turned the engine off for a moment. Some IIDs also require drivers to blow into the device while they are driving, and if the test is failed, the driver is made to pull over. The IID will not shut off a vehicle until it is in park, however, the horn usually starts honking and lights start flashing, making it impossible to continue driving. Once you pull over, the car will stop and you won’t be able to start it again until your BAC is under the legal limit.
