How the Ignition Interlock System works

Install your interlock system

Get your ignition interlock installed by a certified installer. Installation only takes 1-3 hours, depending on the type of car. Our installers are across the US.

Use the interlock system before driving

The driver will provide a breath sample into the unit before starting the vehicle. If the breath sample meets the State set alcohol requirement, the vehicle can be started.

Service the interlock system

The device will need to be serviced every 30, 60 or 90 days. Some state requirements allow the service to be done by our mail-in exchange program.
