Installing an ignition interlock device with us is very quick and convenient. If you own more than one vehicle in your household, you may ask: Do I need an interlock device on all vehicles? The simple answer: No, not necessarily. This post will further explain this topic.
Do I need an interlock device on all vehicles I own?
No. In Louisiana you are required to have an interlock on whichever vehicle you choose to drive.
You may choose to install interlock devices on several vehicles in your household or in a fleet of business vehicles if it’s more convenient, but you don’t need to install devices on vehicles you won’t drive.
We’ll let you know if your situation requires anything different when we set up your appointment.
