Two Steps, One Sticker
Texas combines inspection and registration: pass inspection first, then renew your registration and receive a single sticker. Check the Texas DPS and TxDMV websites for current rules, as requirements may change.

Common reasons cars fail
Most failures are inexpensive fixes:
- Check engine light on
- Burned-out headlights, brake lights, or plate lights
- Worn wiper blades
- Horn not working
- Worn tires below 2/32 inch tread
Monitors not ready
If your battery was recently disconnected or codes were cleared, readiness monitors may not be set. Drive normally for a few days before inspection.
