In case a mix of vehicle classes is present, for instance, a truck and a car, separate transponders will be required. This is because toll agencies are usually charging different amounts per each vehicle class and hence having a different class transponder means that an inappropriate toll will be remitted.
3. Manual Transfer of the Transponder:
Under this system, even if you have several automobiles linked to the same account, the E-ZPass transponder will have to be relocated from the first car to the other one physically. This indicates in a situation where the vehicles are changed often, the first one will have to be stripped of the transponder and the new vehicle will be given it. If the vehicle owner happens to forget the movement of the transponder, they could experience toll violation or mischarge.
In summary, sharing your E-ZPass between cars is possible, but it requires proper registration and manual transfer to ensure accurate toll charges.
