Public Transportation Vehicles & Qualifying Van Pools

Capital Metro Buses, Metro RideShare Van Pools, Metro Access and CARTS vehicles are exempt on CTRMA toll roads. If you are a part of one of the mentioned programs and are receiving CTRMA bills, please contact your program manager. Program managers provide us with information necessary to ensure exemption. We may have outdated information.

Metro RideShare drivers seeking refunds for CTRMA transactions debited from TxTag accounts should initiate a dispute by contacting TxTag and indicating they are exempt on CTRMA roads. This can be done online using the dispute issue category or over the phone with an agent by calling 888-468-9824.


The Board Members and staff of the Central Texas Regional Mobility Authority honor and appreciate the service of the men and women of our military forces, past and present.

State law allows a Texas toll road entity to offer discounted or free tolls for vehicles with a Disabled Veteran, Purple Heart, or Legion of Valor specialty license plate; however, the Mobility Authority does not offer discounted or free tolls under such a program at this time.

Although we are not currently offering discounted tolls at this time, CTRMA’s board has authorized a Veteran’s Discount Program for Qualified Veterans to go into effect later this year. Full details on program participation will be available prior to the launch of the program, currently scheduled for November 2018. Visit our FAQ’s for more information on this upcoming program.

In the meantime, Veterans and other beneficiaries may be eligible to have toll charges reimbursed by the U.S. Department of Veteran’s Affairs when they use a toll road to travel for care at a Veteran’s Administration medical facility. The Beneficiary Travel Benefits program is established and administered by the Veterans Administration. For more information, questions, or assistance relating to the Beneficiary Travel Benefits program, please contact the Veterans Administration Beneficiary Travel Office at (254) 743-0749.
