About Ignition Interlock Devices

Unfortunately, a DUI conviction can carry with it penalties that go above and beyond the typical, expected fines and jail sentences. Depending on one’s unique circumstances, an offender may face, in addition to jail time and fees, a period of license revocation, required attendance in an alcohol treatment program, and the mandatory installation of an ignition interlock device in his or her personal vehicle.

What Is an Ignition Interlock Device (IID)

One who is charged with a second, third, or subsequent DUI offense may be asked to install an ignition interlock device (IID) into his or her vehicle. IIDs do not allow drivers to start their automobiles until they have taken and passed a breathalyzer test. The driver must blow into the mechanism and register a blood alcohol content (BAC) level below a preset limit, which is most commonly 0.02 (well below the legal limit of 0.08). When this is complete, the vehicle can be turned on.

Should a driver fail the breathalyzer test, then the vehicle will not start. Typically, the driver will be tested a second time after setting the automobile in motion. This measure should prevent drunk drivers from cheating the system by having a sober person blow into the device to start it. If a driver fails this second breathalyzer, then the vehicle will set off an alarm in order to alert local law enforcement of this breach.
