About this site & disclaimer

Not affiliated with the government

Bexar Emissions Guide is an independent, privately run information site. It is not affiliated with, endorsed by, or operated by the State of Texas, the Texas Department of Motor Vehicles (TxDMV), the Texas Department of Public Safety (DPS), the Texas Commission on Environmental Quality (TCEQ), Bexar County, the City of San Antonio, or any inspection station. We can't renew your registration, run an inspection, or issue waivers.

How we write the guide

• Every rule, fee and date comes from an official government source, linked on the page where it is used. The full list is on the Sources page.
• Where the official sources are unclear or disagree, we say so in a highlighted box instead of guessing.
• Pages are reviewed when the official sources change. Last full review: October 2026.

Not legal or mechanical advice

This site is general information only. Your TxDMV renewal notice, your county tax office and DPS-certified inspection stations have the final word on your vehicle. If anything here conflicts with an official source, the official source is correct.

How the site is funded

The site may show advertising and includes clearly labeled affiliate links (for example, Amazon links to OBD2 code readers). As an Amazon Associate I earn from qualifying purchases. We don't accept payment from stations or repair shops for placement. See the privacy policy.
