An ignition interlock device is a  breath-testing device that is installed in a vehicle and is connected to the ignition, horn and headlights. To start the vehicle, a driver must blow into the device without registering a blood alcohol concentration (BAC).

Missouri law requires any person guilty of a second or subsequent intoxication-related traffic offense to install an ignition interlock device on any vehicle they operate before reinstating driving privileges.

The Missouri Department of Transportation (MoDOT) maintains a list of approved ignition interlock devices and locations where they can be installed. In addition, MoDOT contracts with the University of Central Missouri, Missouri Safety Center to coordinate and monitor ignition interlock providers.

Each ignition interlock provider is responsible for reporting ignition interlock compliance to the  Department of Revenue and/or the court-ordered supervising authority.
