How to Mount Your Transponder
You must mount your transponder in accordance with the instructions provided below. If your transponder is not properly mounted, your transponder may not be read, and you may incur a higher toll rate as a result. You will be responsible for paying the higher toll rate.
- Sit inside your vehicle facing forward. Select a location behind and to the right of the rearview mirror. The spot should be at least 1″ below the vehicle’s frame and at least 1″ to the right of the rearview mirror, and not within any tinted area. The area should be clean and dry.
- Do not remove the adhesive fasteners from your transponder. Simply peel off the plastic backing to reveal the sticky surface of the fasteners.
- With the E-ZPass logo facing you, right side up, affix the entire E-ZPass transponder to the selected spot on the inside of your windshield.
- Press the entire transponder assembly firmly into place. Hold for two seconds. The installation process is now complete.
Additional fasteners are available if you need to transfer your E-ZPass transponder to another two-axle vehicle listed on your account.
