New, simple way to get HOV toll discounts!

GoCarma is the new and only way to get HOV toll discounts on all DFW TEXpress Lanes. See below for more information.

Carpoolers, motorcyclists and most vanpoolers who use the TEXpress Lanes are eligible for an HOV discount.

ATTENTION: HOV drivers who previously used Drive On TEXpress to pre-register for HOV discounts must switch to the GoCarma app to continue receiving HOV discounts. For everything you need to know about switching over to the new app available now, visit

Please note, the GoCarma app is an independent platform developed by Carma Technologies Corporation through a contract with the North Central Texas Council of Governments.

HOV Discount Qualifications

You will qualify for an HOV toll discount as long as:

  • You have at least two people in the vehicle, such as a driver and a passenger (motorcycles do not require a passenger).
  • You have a valid TollTag, TxTag or EZ TAG account in good standing (i.e. cannot fall into a negative balance)
    • Your Tag must be properly mounted on your vehicle’s windshield—including motorcycles—for our scanners to read them.
  • Your trip is during HOV weekday peak travel periods (Monday – Friday, 6:30 a.m. to 9 a.m. and 3 p.m. to 6:30 p.m.) on these corridors:
    • LBJ TEXpress Lanes

Activating the HOV Discount

GoCarma eliminates the weekly/daily pre-registration, the 15-minute wait for HOV activation and the 10-minute wait for HOV deactivation.

With GoCarma, you simply register once and start saving. The app uses Bluetooth to automatically verify that you’re part of a carpool. Motorcycles registered through GoCarma will always be reported with an HOV status.
