Bexar County emissions test exemptions
The Bexar County program covers gasoline-powered vehicles 2 through 24 years old. Here is who is left out, and the official source for each.
| Vehicle | Emissions test? | Source |
|---|---|---|
| Electric-only vehicles | Exempt ($200 annual EV fee applies at registration) | TCEQ, DPS, TxDMV |
| Diesel vehicles | Exempt | TCEQ, 30 TAC §114.50 |
| Motorcycles and mopeds | Exempt | TCEQ, 30 TAC §114.50 |
| Gasoline vehicles 25 years old or older | Not covered (program covers 2–24 years) | TCEQ, TxDMV #003-26 |
| New vehicles, until their second anniversary | Not yet. Testing begins with the vehicle's second anniversary. | TCEQ |
| Vehicles registered as Antique | Exempt | DPS Unique Vehicles, 30 TAC §114.50 |
| Vehicles registered as Classic | Not exempt as a class. The usual age and fuel rules apply. | DPS Unique Vehicles |
| Military tactical vehicles | Exempt (not personal vehicles owned by service members) | 30 TAC §114.50 |
| Vehicles that run only on natural gas/propane and cannot use gasoline | Excluded | 30 TAC §114.50 |
| Hybrids, plug-in hybrids, flex fuel | Expect a test. They run on gasoline. | See note below |
| Motor homes / RVs (gasoline) | Tested. Call the station first about equipment. | DPS Unique Vehicles |
| Commercial vehicles | Emissions rules apply by fuel and age, plus the commercial safety inspection | TxDMV, DPS |
Hybrids: no official page we found names hybrids directly. DPS says "all gasoline powered vehicles from 2 through 24 years old" in emissions counties get the OBDII test, and the only electric exemption it names is for electric-only vehicles. That is why we say hybrids should expect a test. Confirm with a station if you are unsure. DPS inspection criteria.
Exact age cut-off: TCEQ describes the covered group as "model-year 2 through 24 years old … beginning with the vehicle's second anniversary." It doesn't spell out how a model year lines up with a specific renewal month. If your vehicle is right at 2 or 25 years old, go by your TxDMV renewal notice (it says when an inspection is required) or ask the station.
Vehicles kept outside Bexar County (students, long trips, out-of-county use)
DPS describes exceptions for vehicles registered in an emissions county but not primarily operated there. Examples include a student's car at a school outside the area, a vehicle kept at a hunting property or vacation home in a non-emissions county, a fleet vehicle permanently based at a branch office elsewhere, or an owner who has moved away.
Unclear: the DPS page says this exemption is processed "at the time of the vehicle's annual vehicle safety inspection." That page predates the end of safety inspections for most vehicles (Jan 1, 2025), and DPS hasn't said how Bexar owners use this exception now. Contact DPS Vehicle Inspection or your county tax office before relying on it. DPS Emissions Testing FAQ.
Not an exemption, but related
- Unexpired registration: you don't need a test until it's time to renew (DPS).
- Renewing a Nov/Dec 2026 registration before Nov 1, 2026: no test needed for that renewal (TxDMV #003-26). Details.
- Failed the test? Waivers and extensions exist, but only after a failed test. See options.
