Missouri Ignition Interlock Devices In DWI Cases

In Missouri, certain DUI offenders are required to install an ignition interlock device (IID) on their vehicle. An IID is a breath testing device about the size of a cell phone, that is installed into the steering column of a car. The IID requires an individual to provide a sober breath sample before a car's ignition will be turned on.  Any test result over .30 will not start the ignition.  The IID will be installed on the vehicle and will remain there for the entire time it is required. Any person who wishes to operate the vehicle must use the device in order to start it. Random breath samples are required periodically while the car is in motion to prevent a sober friend from starting the vehicle. Failure to provide a sample or a sample over the requisite BAC level (.05) will result in the sounding of alarms. Three minutes will be allowed between sample and alarm - thus if it is unsafe to provide the sample while driving, the driver will be given enough time to safely maneuver off the roadway to blow into the device before the alarm will sound. The device will never immobilize the vehicle, so that accidents may be prevented.

The IID will be installed on all vehicles the DUI offender owns and operates on a regular basis. The IID MUST be installed in the vehicle for the requisite time period, or the DUI offender's driving privliges will not be reinstated. 

IID's are installed at designated ignition interlock service centers. The DUI offender is responsible to pay the cost of installation as well as the monthly payments.

IID's are designed to prevent any tampering. Attempts to tamper or circumvent the device will result in imposition of further penalties.
