If you always stay in the right-hand lane you will come upon the toll booth for cash paying drivers. If you stay in the left lane and proceed through the toll area (which is for sunpass vehicles only) that's where you will encounter the problem. If you think back to your travels try to remember if you were in the left hand lane. Probably difficult to recall but I'm sure that's where the problem for you exists. Also, when you get a detailed list of your violations, it will describe exactly which lane you were in when you went through the toll.
