To sign up for an E-ZPass, apply online or in person at the E-ZPass Customer Service Center for the area where you do most of your driving. You can also ask the center to mail an application form. E-ZPassiag.com lists all the centers and offers links to their websites.
The E-ZPass is accepted by 26 toll agencies in 15 states. E-ZPassiag.com offers a map showing where the E-ZPass is accepted. Different centers offer various types of E-ZPass accounts but all require you to prepay a set amount into your account as a new user. You then fix a transponder to your car windshield so that tolls are collected electronically from your account as you drive through a designated lane.
