Stone Oak's Next Registration Renewal Now Includes an Emissions Test. Here's What the First Weekend Showed

November 5, 2026
On the morning of Sunday, November 1, people were lined up at inspection stations across Bexar County for a test that most of the stations couldn't run yet. MySA reported that a coding problem in a state database blocked most stations. At first, the outlet could confirm only three Official Inspection Station branches were testing: 10480 Culebra Road, 9000 Huebner Road and 324 E. Nakoma Drive. Charissa Barnes, CEO of Texas Tag & Title and Official Inspection Station, told MySA that customers at several stores had waited well over an hour while the company and its equipment vendor worked through the problem with state agencies.
By 1 p.m. the problem was gone. In a statement reported by News4 San Antonio, the Texas Commission on Environmental Quality said the coding issue had been fixed countywide and every enrolled station could test. With the stations working, how this goes for a Stone Oak household now depends on the month its registration expires and whether a check-engine light is on.
The fix also came with a deadline extension. TCEQ said drivers whose registration expires in November and who couldn't test before the fix have until November 30 to pass and register. If your sticker expires this month, that date is still a few weeks away as this post goes up.
There are plenty of stations. In July, MySA counted just over 250 Bexar County sites in the Texas Department of Public Safety station locator, and Barnes estimated closer to 350. Both numbers date from before launch. To find a certified station close to US 281 and Loop 1604, use the DPS active station locator. Official Inspection Station also lists its branches on a locations page.
With stations open, the question that matters is whether your vehicle has to be tested at all.
TCEQ's program highlights say the annual test covers gasoline vehicles from 2 to 24 years old, starting at the vehicle's second anniversary. In Bexar County, model year 1996 and newer vehicles get an onboard diagnostics test, which reads data from the car's computer.
In a typical Stone Oak garage, that sorts out like this, based on TCEQ's program overview:
What decides whether you test is the county where the vehicle is registered. TxDMV's registration page says non-commercial vehicles "registered in one of the following 18 counties … must still obtain a passing emissions inspection prior to registration," and Bexar is on the list. Stone Oak is in Bexar County, so a Stone Oak address puts your gasoline car in the program.
The headline number is $18.50. That's what Bexar County stations charge for the test as of November 2026, and TCEQ also lists a $2.50 state administration fee collected at registration. Neither one replaces the $7.50 inspection-program replacement fee that DPS says noncommercial vehicles already pay statewide.
| Charge, as of November 2026 | Amount | Who sets or collects it |
|---|---|---|
| Emissions test at the station | $18.50 | Paid at the inspection station |
| State administration fee | $2.50 | Collected at registration, per TCEQ |
| Inspection-program replacement fee | $7.50 | Statewide for noncommercial vehicles, per DPS |
Bexar County doesn't keep any of the new test fee. "This is something new throughout the state. There's also going to be a charge of $18.50 when you get your emissions test done. County does not keep any of that money," Bexar County Tax Assessor-Collector Albert Uresti told News4 San Antonio. The money goes to whoever does the test and to the state.
A failed test is what really costs you. Under DPS's Bexar County FAQ, a vehicle that fails its first test can be retested free at the same station within 15 days, under conditions DPS spells out. Official Inspection Station goes further. MySA reported that drivers there get a year to finish repairs without being charged a second time.
Official Inspection Station ran test sessions before the November 1 launch so drivers could see where they stood. According to MySA, those early runs showed catalytic converters and check-engine lights were the most common reasons cars failed. An illuminated check-engine light is something you can see in the driveway before you ever pull into a station.
The test doesn't take long. The state estimates 15 to 20 minutes, based on watching inspections at Austin stations, and Barnes told MySA she hopes to get it to about 10 minutes in the coming weeks or months. She also put the first weeks in context: "And at the end of the day, it's new for all of us. It's all new for DPS."
The test itself is short. What takes time is fixing a car that fails, and that's why the timing below matters.
DPS says you don't need the test until your current registration comes up for renewal. News4 San Antonio, citing TxDMV, reports that you can renew up to 90 days before expiration and that a vehicle needing the test has to be inspected within that 90-day window. Once it passes, you can renew online, by mail or in person.
Put that together with the 15-day free retest and you get a simple order of steps for any household with more than one gasoline vehicle:
A car whose sticker expires next summer won't need a test for months. A car expiring in December or January is close to or already inside its window.
This fall, some of the strongest pushback against the program came from north San Antonio officials. MySA reported that District 9 City Councilwoman Misty Spears and Bexar County Precinct 3 Commissioner Grant Moody met with federal EPA and state staff to try to stop the rollout, pointing to the cost to drivers. On October 28, News4 San Antonio reported that both the state and the EPA had denied the request. "There's been rumors going around that the entire emissions testing requirements was put on hold and that's simply not correct," Uresti said.
Local officials couldn't simply turn the requirement off because it comes from federal air-quality rules. According to TCEQ's adopted state plan for Bexar County, EPA classified Bexar County as being in moderate nonattainment of the 2015 ozone standard, and under the Clean Air Act that classification requires a basic vehicle inspection and maintenance program. TCEQ adopted the state plan. EPA approved it in a Federal Register rule published April 8, 2025, which says Bexar County onboard diagnostics inspections begin November 1, 2026.
The program stops at the county line. TCEQ's overview names Bexar County alone as the San Antonio program area. TxDMV's list of affected counties includes Bexar but not Comal, Guadalupe or Kendall, so a car registered in one of those neighboring counties isn't in the program. For anyone registered in Bexar County, the test is now a yearly step before every renewal.
