it works pretty well down here in MD. Best thing the DOT has done in a while. I'm hoping that it becomes the norm everywhere, although it might just be an East Coast thing. From what I understand, it works from Northern VA, up I-95 to NJ. It also works at most other toll stops in MD, VA, and parts of PA & OH.

I really wish that eventually you don't have to slow down at all for it to register, but it sure beats waiting in those lines when I need to get to the Eastern Shore of MD.
