Ignition Interlock

Impaired driving contributes to more than 25 percent of all Missouri traffic fatalities

A breath alcohol ignition interlock device (BAIID) is a breath testing device, including all parts necessary for operation, e.g., handset and camera, installed in a vehicle that prevents it from operating if the breath test registers a breath alcohol concentration that meets or exceeds the alcohol set point.  The device also requires the driver to continue to pass repeated breath tests while the vehicle is running to ensure that the driver remains below the alcohol set point.  However, the interlock device will not interfere with the normal operation of the vehicle while it’s in use.

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.

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