    intoxalock don't really support you when you need them. they report you to the DMV if you don't drive and blow every 15 minutes on the freeway.(drive and blow!) is very distractive around 18 wheelers and fast drivers. you have to look into the device til it reads (BLOW) or blow harder or try again. reading freeway signs and watching traffic. and yet, they want you to be safe when driving. it's easier said than done.Expensive &t hey charge every two weeks.59.99. Drive,Blow and Die!

Frequently Asked Questions About Intoxalock Ignition Interlock

How does an interlock device work?

An ignition interlock device (IID) is a small breathalyzer installed in your vehicle to prevent it from starting if alcohol is detected on your breath. Before driving, you'll blow into the device. If your breath alcohol concentration (BrAC) is below the programmed limit, the car starts. Periodic retests occur during your trip to ensure continued compliance.

What is the cost of an ignition interlock device?

The installation of an ignition interlock device, often called a car breathalyzer, typically costs between $70 and $150. This one-time fee is paid at the start of your lease and covers the service center's labor to install the device in your vehicle. Payment is made directly to the service center at the time of installation. For more on cost breakdowns, you can read our cost of ignition interlock device guide.
