Residents of Travis County must have their vehicles emissions system tested once a year using a new, improved testing system. This test is part of the annual safety inspection administered by the Texas Department of Public Safety (DPS). The reason for using the new emission test is to reduce air pollution caused by gasoline powered vehicles that don't function properly.

A vehicle that fails the emissions cannot be registered. It is illegal to drive a vehicle that is not registered in the state of Texas and the driver could be ticketed.

YES. Travis County administers the Air Check Texas: Drive a Clean Machine Repair and Replacement program which provides limited assistance for low-income individuals and families with eligible vehicles in Travis County.

Travis County pays the repair facility directly, and we can pay no more than $600 for a repair. You must pay the first $30 of the repair bill and any costs over $600 or we can pay up to $3,500 toward the cost replacement/retirement of your vehicle.

To be eligible for assistance, you must:

  • Have a total annual family net income (after taxes) that meets program guidelines, listed below.

***As determined by using the Adjusted Gross income (AGI) on your most recent Federal Income Tax form.
Note: The value of the replacement vehicle may affect eligibility requirements and/or benefits for financial assistance programs, such as Temporary Assistance for Needy Families (TANF). Please contact your case worker if you have any questions.

  • You may automatically be eligible for assistance if you already receive financial assistance from federal, state, or county social services, including Supplemental Security Income (SSI), Temporary Assistance to Needy Families, Medicaid, Food Stamps, or other public programs.
  • Have a vehicle 2 to 24 years old that has:
    • Failed the AirCheckTexas emissions test;

    • Been registered in Travis County for 12 of the past 15 months; and
    • Currently registered; and
    • Is able to be driven to a recognized emissions repair facility.

If your vehicle is unable to be repaired, or you choose to replace your vehicle rather than repair it, the program can assist in the purchase of another vehicle. In order to be eligible to replace/retire a vehicle, you must:

  • Meet the vehicle guidelines;
    • Passed the DPS safety and emissions inspection within the previous 15 months;

The vehicle owner contacts Travis County by calling (512) 854-5020. The application form is available at emissions testing and repair sites and under "Helpful Links". Supporting documents include:

  • Vehicle Inspection Report (VIR) which the AirCheck Texas inspection station gives you at the end of the safety and emissions test;
  • A copy of your most recent federal income tax return or copies of pay stubs for all members of your family who have worked during the previous three months or latest paycheck stubs if Year-to-Date (YTD) is provided; or
  • A case or identification number for SSI, Temporary Assistance to Needy Families, Medicaid, Food Stamps or other public program.

You can fax the application and supporting documentation to (512) 854-5021. You must apply for the program, no later than 30 days from the date your vehicle fails the emissions test.

As soon as we have verified that your family income meets the guidelines and your vehicle is eligible, we will issue a voucher along with a list of DPS Recognized Emissions Repair Facilities that perform emissions-related repairs. This process will be completed within 3-4 weeks after receipt of the application. A voucher will be mailed or a letter explaining why your vehicle is not eligible.

No. All repairs must be performed by a DPS Recognized Emissions Repair Facility. Furthermore, you must use a repair facility from the list provided with the voucher since Travis County has an agreement with these facilities to participate in the program.

No. We can only help you repair the vehicle's emissions systems. You are responsible for making sure that your vehicle passes the safety portion of the inspection. If you have questions about applying for AirCheckTexas financial assistance, call us at (512) 239-0301

Each repair or replacement voucher is valid for 30 days. If you need an extension, call 512 854-5020. An extension must be requested within 5 business days of expiration.

It is your responsibility to pay for all repairs that exceed the cost of the voucher ($600). You can request to exchange a repair voucher for replacement voucher. However, your vehicle must qualify for a replacement voucher to be eligible.
