To pay a toll in Maryland with E-ZPass, sign up for an E-ZPass account, prepay a toll balance into the account, and purchase a transponder to attach to your vehicle's windshield. As you drive through the toll lane, the toll booth's antenna charges the toll electronically to your E-ZPass account.
An easy way to sign up for an E-ZPass account is to purchase a packaged E-ZPass On the Go account at a participating retailer. The package includes a prepaid toll balance and a transponder. You can use the transponder to pay for tolls immediately, so long as you register it online at the E-ZPass Maryland website within seven days of first use. Visit EZPassMD.com for details of this and other E-ZPass plans and to find participating retailers' locations.
