As a Michgan Attorney who deals in DUI’s and Drivers License Restoration, I was once asked in an interview about the Interlock Ignition Device.

This device is basically something for the drivers license restorations. When you are successful at that hearing then for the first year and thereafter they will require that you have installed in your vehicle and ignition interlock device. And that means that anybody that operates that vehicle must blow in it first before the engine actually starts and then sometimes people will have a work vehicle. That also means that any co worker that starts this work vehicle also must blow.

So you’ve got to be able to trust your co workers in regards to that. It’s not that rare of a situation where it’s workmen that have work trucks and the likes.
