Electronic Tag

What are Electronic Tags and How Do They Work?

Electronic tags are an electronic payment method that automatically pays for tolls as you drive on toll roads. Sign up for an electronic tag account with any of the tags accepted on Mobility Authority facilities (see the full list below). The tag provider will then send a tag that you mount to the inside of your windshield behind the rearview mirror. When you drive on a tolled facility, an electronic reader above the toll road will read the microchip inside the tag and cameras take a photo of your license plate. If you have an active account (information is up-to-date and sufficiently funded), the price of the toll will be debited from your account. If you don’t have an electronic tag or your account is not up-to-date or funded, you will receive a Pay By Mail bill.

The Mobility Authority currently accepts TxDOT’s TxTag, NTTA’s TollTag, HCTRA’s EZ TAG, Kansas Turnpike Authority’s K-Tag, Oklahoma Turnpike Authority’s Pikepass, Florida Turnpike Enterprise’s SunPass, E-470’s ExpressToll, and BancPass/PlusPass. The Mobility Authority is continuously working to become interoperable with other agencies.

What Could You Save?

You’re busy with life and paying your toll bill by mail takes time away from what’s really important. Paying toll bills by mail isn’t just a hassle — with higher toll rates, processing fees and other charges, it’s also more expensive. What could you save by leaving Pay By Mail in the rearview mirror? It may be a lot more than you realize …

Get an idea just how much money you could have saved driving on Central Texas Regional Mobility Authority Roads in the past with our Savings Calculator below.

To see what you could have saved on toll rates, enter your license plate number and select a date range. Remember to calculate the time period in which you’ve driven the car tied to the specific license plate number you enter.

* This savings number reflects the difference between Pay By Mail and electronic tag payment rates for tolls incurred by the plate holder during the date range indicated. The savings number does not include processing fees or late fees. Savings displayed will reflect the most recent Pay By Mail account associated with the license within the selected date range.

The calculator allows you to see how much more you’ve paid just in the Pay By Mail program’s higher toll rates. It’s important to note that the total dollar amount from the calculator doesn’t include other fees, such as late fees.

The calculator above shows you the monetary savings, but the time and hassle saved is incalculable. The Mobility Authority creates mobility solutions in Central Texas to make your life easier, and we want the process of paying your toll bills to be the same, that’s why we accept multiple electronic tags on our roads.
