Frequently Asked Questions

How does MACPASS work?

The MACPASS transponder is a small electronic device that attaches to the windshield of your vehicle and contains information that identifies your account. As you approach a toll lane, on either the MacKay or Macdonald Bridges, an overhead antenna identifies your MACPASS transponder and deducts the toll.
