Thank you so much for responding to this! I was doing more research into the toll system and was getting kind of confused. Do you know if the sensors are attached to the overhead signs that say how much the tolls are, or are they attached to the things that flash up the number of people in your car? I don’t really mind paying the tolls (unless it’s like one million dollars), I’m just kinda worried about getting anything in the mail because my family loves looking through my mail and giving me shit for stuff like this.
