FAQ
Can I use both my vehicle’s built-in transponder and a 407 ETR-issued transponder at the same time?
Once registered, the built-in device functions as a 407 ETR transponder, however, if you prefer to use a mounted transponder, you can do so provided that the transponder-equipped vehicle’s functionality is turned off. If you use both transponders at the same time, you will be invoiced through your 407 ETR-issued transponder.
