E-ZPass is an electronic toll collection system used on toll roads, toll bridges, and toll tunnels in the Eastern United States, Midwestern United States, and Southern United States. The E-ZPass Interagency Group (IAG) consists of member agencies in several states, which use the same technology and allow travelers to use the same transponder on toll roads throughout the network.
An E-ZPass system transponder unit, also known as a tag or a pack, was distributed by the Massachusetts Turnpike Authority for use with their E-ZPass-compatible Fast Lane system and other roads which utilize E-ZPass.
