I got a letter in the mail for toll not paid, since I don't have an account for them to soak funds from. The picture was of a small Toyota compact, which in no way resembles the F350 dually that the tag is affixed to. Plus, in the picture, it was evident that the tag number they were billing wasn't the tag number shown. I contested it and won.
If I had a Sunpass account, they would have just deducted the toll. I wonder how many frequent tollway users just pay the bill rather than checking to be sure they aren't being charged for usage they didn't use!
