Installing Your TxTag

Read the step-by-step instructions below to learn how to correctly install the TxTag sticker on your windshield. You can also watch a short video clip on how to install your TxTag by clicking on your windshield type below.

Remember not to peel the backing on the tag until you are ready to stick it to your windshield. Once the tag is placed, movement or removal will damage the electronic chip inside.

Installing your tag is easy:

Step 1     Step 2     Step 3
  • CLEAN: Clean and dry the inside of your windshield. The windshield's temperature must be above 50º F 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 4" below the top edge of the windshield and/or tinting.
  • STICK: Peel off the backing and stick the gray side to the inside of the windshield. Smooth the tag against the glass so you have a tight seal. Once installed, the blue label and TxTag logo should be visible when sitting inside the vehicle.

Your tag may not work if it is not properly installed, and you may be charged incorrectly for your tolls or be fined for failure to pay on other toll authority roads in Texas. Here are some common mistakes to avoid:

  • Not sticking the tag to the windshield – Your TxTag sticker must be permanently installed in the correct 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 the 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 the tag to a cold windshield – The windshield's temperature must be above 50º F for the tag adhesive to stick properly. If it is colder than 50º F, 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. You could also be charged twice if both tags are read. Install only one electronic toll tag in your vehicle.
