Missouri Ignition Interlock Device Installation Guidelines

Missouri ignition interlock device program guidelines differ from case to case. You may be eligible for an ignition interlock device after your initial license suspension. After a DUI conviction, you may apply for a restricted license, which allows you to drive under the condition that any motor vehicle you operate is outfitted with an ignition interlock device.

The length of your IID requirement depends on the severity of your offense and is determined by the Missouri Department of Motor Vehicles.

As a state-certified provider, Low Cost Interlock devices meet all Missouri Department of Transportation standards for accuracy, reliability, and tamper detection.
