Completing a TX Vehicle Inspection

Safety Inspections

To complete a vehicle safety inspection in Texas, visit a DPS-certified inspection station and bring the $7 safety inspection fee.

The state's portion of the fees varies based on vehicle age, type, and location, and are due at the time of registration or renewalnot during the safety inspection.

Once your vehicle passes, you'll receive documentation to present when you register or renew your registration; this information may also be entered electronically. You'll then receive a windshield sticker as proof of passing and valid registration as part of the Two Step, One Sticker program.

NOTE: Generally, safety inspection stations don't require proof of registration or identification; however, it's best to bring these documents as requirements can vary by station.

Failed Safety Inspections

If your vehicle fails, you must have it repaired and retested.

Emissions Inspections

To complete a vehicle emissions check in Texas, visit a DPS-certified inspection station and bring:

After you pass your emissions test, you'll receive a Vehicle Inspection Report (VIR) stating you passed (these reports also state if you've failed). You may obtain a copy of the report for up to 13 months of the inspection date.

Failed Emissions Inspections

If your car or truck fails its Texas smog check, you must have it repaired and retested; if it still fails, it could be eligible for a waiver or extension. These vary from low-mileage waivers for vehicles driven less than 5,000 miles during its inspection cycle, to low-income waivers for residents who qualify.

Visit the TCEQ's Waivers and Extensions page for a full list.

Repair Assistance

If you meet certain location, income, and vehicle requirements, you could be eligible for a repair assistance voucher of up to $600.

Qualifying vehicles must be repaired at an approved emissions repair facility. You'll receive a list from the program administrator when your voucher application is approved.

Learn more about repair assistance requirements and how to apply for a voucher at the state's Vehicle Repair Assistance page.
