That EZPass article...I read it and to me, it was ONLY about speeding thru the EZPASS TOLL BOOTHS....not from entrance to exit.
One state says they give written warnings, other states say they don't bother, one state (NJ, I think) says that if a toll taker sees someone speeding thru a warning will be given. Yeah. That person better have a calibrated radar gun....yeah. I really don't think toll takers get any kind of radar gun qualification classes.
I think they have signs saying something like "45 mph max", but I have run thru at over 50, just keeping up with the traffic ahead of me...and no nothing from the EZPass people.
