Ignition Interlock Device

What is an Ignition Interlock Device?

In most restricted driving programs, random retests are also required as the vehicle is being driven. When requested, the driver must deliver breath samples into the device and the device will log the event. If the result exceeds the pre-programmed level, the Ignition Interlock Device will not turn off the engine while the vehicle is in motion however it will give a signal to stop. Man using an interlock device in his car

The data received from all breath samples are sent to the department(s) (Court/DMV/Probation, etc) who ordered the device to be installed.
