What a PITA . So if a fully automated toll system miss reads a plate and sends you the toll bill, it is your responsibility to prove it was not your plate. Even if that plate is not currently registered!
I now need a letter from the STAAB agency/ Maine DMV stating that my old trailer plate was surrendered 4 years ago. Why? Because the toll cameras miss read a D as a 0 with all other digits matching one of my old Maine plates. The toll system does a lookup in ALL the DMV databases and forwards the toll. With these new fully automated toll systems I recommend saving all your surrendered plate receipts and keep note of all plates you have ever had in your name.
