Ignition Interlock Intervention and Device

The Ignition Interlock Intervention component is available to drivers who violate the ignition interlock device (IID) and are required to attend an intervention session or participate in case management services with the DUI program.

The Ignition Interlock Device is a device installed in a motor vehicle, which prevents the ignition from starting unless the driver blows a breath sample into the device. If the alcohol concentration of the breath sample exceeds 0.05, the motor vehicle engine will not start.


Section 316.193, Florida Statute, requires ignition interlock devices to be installed on the vehicles of persons convicted of DUI. The ignition interlock program began July 1, 2003, but affects anyone who is convicted of DUI after July 1, 2002 upon eligibility of reinstatement for a driver's license.

A person convicted of DUI who applies to the Division of Driver’s licenses for driver's license reinstatement will be directed to an Ignition Interlock provider. The Ignition Interlock device must be installed on the vehicle prior to receiving a license.
