Minnesota does not have toll roads per se, but there are high occupancy toll sections where single occupants can pay a fee to use a lane usually only allowed for vehicles with more then one occupant. This system uses an E-Z Pass transponder, with a switch that allows switching between single and multiple occupancy. They do advertise that this transponder can be used in states with regular toll roads that support E-Z Pass. However, I have not found any information on which setting the transponder should be set to, or if it matters at all.
My assumption would be that setting it to multiple occupants disables the transponder, since that allows toll-free travel in Minnesota anyway. The MN E-Z Pass website alludes to this, but I don't see this specifically stated.
Does anyone know for sure or have any official sources to answer the question on which setting the transponder should be set to on non-Minnesota toll roads?
