Another EZ-Pass toll problem that I've consistently seen is crossing the Delaware Memorial Bridge, between DE & NJ. Every time that I've done it with the EZ-Pass it tries to charge me the commercial vehicle rate of $5 per axle ($20) instead of the advertised rate of $8 for an auto with a two-axle trailer. After several trips that took more than a few months to get a refund credited (the Bridge Authority is a separate entity than DE DOT or EZ-Pass, and is not a very "user-friendly" entity), I stopped using the EZ-Pass on this bridge, and just pull it down, put it in he foil pouch, and just pay the $8 cash when I cross this bridge....
