E-ZPass Warning

Were you aware that if you drive too fast through an "E-ZPass Only" lane you could have your E-ZPass revoked for at least 60 days after your second offense?  I wasn't until today when I got a letter in the mail saying that I was clocked at 34 mph.  Hopefully I was at least going through a 20 mph lane and not a 5 mph.  I never thought I went through those things very fast because you want to make sure that it accepts the pass.  Guess I'll be really careful in the future.  It says that you must be travelling at the postd speed upon entering and exiting the toll lane.
