Illinois DUI attorneyAn ignition interlock device (also sometimes referred to as an “IID” or a “breath alcohol ignition interlock device” (BAIID)) is a tool that can be installed in an auto that prevents the vehicle from turning on if the driver’s breath alcohol concentration (BAC) is higher than a certain pre-programmed level. If an ignition interlock device is installed on your vehicle then you must blow into the attached breathalyzer before you drive. If no alcohol (or a permissible amount of alcohol) is detected on your breath then your car will start as usual, however, if you fail the breathalyzer test then your vehicle will be locked for a predetermined amount of time (generally the vehicle’s ignition will be locked for a few minutes after the first failed test and will be locked for a longer period of time if a second or subsequent breath test is failed). Additionally, some ignition interlock devices also require drivers to submit to random re-testing while driving.

Ignition Interlock Devices in Illinois

Here in Illinois, anyone who is convicted of driving under the influence (DUI) may be required to have an ignition interlock device installed on any vehicle that they wish to operate as a condition of having their driving privileges restored. The penalties associated with driving without an ignition interlock device when required to have one can be extremely steep in Illinois. In fact, notes that driving without an ignition interlock device in Illinois is a Class 4 felony offense that is punishable by imprisonment for up to three years and payment of a fine of up to $25,000.

If you have in fact been drinking and driving, the moment the law enforcement officer collects evidence against you, you are at risk for losing your license, serving jail time, paying hefty fines, and possibly blemishing your future career options, as DUI convictions can often ruin your eligibility for certain jobs.

The BAIID Consequence

Along with having your license suspended, paying fines, and serving possible jail time, you may also face another serious restriction as you reclaim your driving privileges. Should you decide to submit to a blood alcohol concentration (BAC) test upon your arrest and are found guilty of driving while intoxicated, you will likely be required to have a breath alcohol ignition interlock device (BAIID) installed in your vehicle if you are eligible for driving relief. The BAIID installation is required for a set period of time determined by the court, depending on the nature of your conviction, and you are required by law to utilize it any time you get behind the wheel.
