Like other states, Illinois utilizes ignition interlock devices in its approach to drunk driving. An IID is a device installed in a vehicle that controls the vehicle’s ignition, keeping it locked until a driver provides a clean breath sample proving they are not under the influence of alcohol. Only when this happens can the person start and drive the vehicle. The goal of IIDs is to reduce repeat instances of drunk driving. 

There is much that most people likely do not know about life with an ignition interlock device. One reality is that drivers are regularly but sporadically prompted to provide breath samples while they are driving, after they have already passed a test to start their vehicles. Car and Driver magazine indicates that these tests are called rolling retests and drivers have a limited amount of time in which to complete them lest a series of alarms may be initiated that could include their horn honking and lights blinking until they stop. 

An ignition interlock device rolling retest has been found to cause cognitive, visual and manual distractions for drivers. Several vehicle accidents have been linked to the participation on the part of the driver in a rolling retest. The fact that a person convicted of drunk driving must perform an action known to be dangerous when behind the wheel is certainly confusing.
