Do not peel the backing on the tag until you have found the right place on your windshield. Once the tag is placed on the windshield, removal will damage the electronic chip inside.

Installing your tag is easy:

Clean and dry the inside of your windshield Your tag goes behind the rearview mirror. Peel off the backing and stick the gray side to the inside of windshield
  • CLEAN: Clean and dry the inside of your windshield. The windshield’s temperature must be above 50ºF for the tag to stick.
  • POSITION: Your tag goes behind the rearview mirror. Please see options above. The tag will not work if it is in the wrong place, sideways or upside down, and it must be placed four inches below the top edge of the windshield and/or tinting.
  • STICK: Peel off the backing and stick the gray side to the inside of windshield. Smooth the tag against the glass so you have a tight seal. Once installed, the TxTag logo should be visible on the tag when sitting inside the vehicle. Please see picture below.
Correct TxTag installation

Important: Incorrect installation can keep your tag from working properly. If the equipment in the toll lanes can’t read the electronic signal from your tag, then it cannot recognize you as a TxTag customer. This means that you could get a violation notice. Here are some of the most common installation mistakes:

Common mistakes to avoid

  • Not sticking the tag to the windshield
    Your TxTag sticker must be permanently installed in the right place on your vehicle's windshield. DO NOT hold up your tag with your hand, wave it, attach it to a sun visor or place it outside of the vehicle.
  • Installing tag too close to metal
    Installing your tag too close to metal can interfere with the tag’s electronic signal. The tag must be at least four inches away from the top edge of the windshield.
  • Applying tag to a cold windshield
    The windshield’s temperature must be above 50ºF for the tag adhesive to stick properly. If it is colder than 50ºF, use your car’s heater/defroster to warm the windshield. Dry off any condensation before applying your tag.
  • Installing more than one toll tag
    If you have another type of toll tag on your windshield, its electronic signal may interfere with your TxTag’s signal, causing it not to be read. Your account could also be charged twice. Please install only one electronic toll tag in your vehicle. Check with the TxTag Customer Service Center or the other toll tag provider if you have any questions.
