Anyone can sign up with the GoCarma smartphone app.
During the setup process, you'll simply provide your name, email and phone number.
You will have the option to add your vehicle details to become eligible for HOV toll savings in TEXpress lanes. Once you add the details, we'll send you a GoCarma Pass - a small Bluetooth device to keep in the glove box.
Once signed up, the app will automatically verify when you're in a registered vehicle. Each person in the car should download GoCarma and sign up.
