You can find the prices for E-ZPass tolls online at E-ZPassIAG.com. The E-ZPass link near the center of the home page directs individuals to the Get E-ZPass page that lists links to each participating state's E-ZPass website. I-PASS and North Carolina QuickPass links are also listed.
Each site is uniquely designed and worded, and each site's home page lists links to cost information differently. For example, toll rates are found on the Maryland E-ZPass site, EZPassMD.com, by clicking the Toll Rate Calculator link. The E-ZPass New York site, E-ZPassNY.com, lists toll rates under Plan Descriptions via the E-ZPass Info link at the top of the home page.
