The GoCarma app is available to download for free for iPhone and Android phones.
During the setup process, you'll simply provide your name, email and phone number.
You should then add any vehicle you regularly travel in on Dallas-Fort Worth TEXpress Lanes.
Once you have completed the sign up process, you should see a “Setup OK” confirmation in a blue bar at the top of the home screen.
Then you’re all set! The app will automatically activate whenever you travel in a TEXpress Lane during weekday peak periods.
