E-ZPass

E-ZPass

E‑ZPass is an electronic toll-collection system used on most tolled roads, bridges, and tunnels in the northeastern United States, south to Virginia and West Virginia, and west to Illinois. Currently, there are 25 agencies spread across 14 states that make up the E‑ZPass Interagency Group (IAG). All member agencies use the same technology, allowing travelers to use the same E‑ZPass transponder throughout the IAG network. Various independent systems that use the same technology have been integrated into the E‑ZPass system. These include Fast Lane in Massachusetts, I‑Pass in Illinois, i‑Zoom in Indiana, and the defunct M‑Tag in Maryland, and Smart Tag in Virginia.
