    The continual testing while driving is a nuisance and possibly dangerous. You make laws about texting and driving yet you want this continual testing which yes you can pull over. Pulling over interferes with time sensitive driving. It's just overkill, why would somebody choose to drink while driving after being sober for initial start. What's next a CPAP mask while driving?

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.
