Local shop owners and drivers got a live demonstration of emissions testing in San Antonio, as officials and industry leaders urge early pre-screenings ahead of new regulations impacting Bexar County.
Official Inspection Station/Texas Tag & Title
A major shift in how vehicles are inspected in Bexar County is on the horizon, and local shop owners got a hands-on preview Thursday of what drivers can expect.
At a live demonstration hosted by Official Inspection Station Texas Tag & Title, located at 10480 Culebra Road on the city’s West Side, drivers watched emissions testing play out in real time — complete with instant pass-or-fail results — ahead of new rules set to take effect Nov. 1.

The event, titled “Will You Pass the Inspection?”, walked attendees through the process, showing how technicians connect directly to a vehicle’s onboard computer to evaluate emissions systems, replacing the traditional safety inspections that ended in 2025.
Organizers say the change will impact nearly 2 million vehicles across Bexar County.

Charissa Barnes, CEO of Official Inspection Station, said her company has been preparing for this transition for years.

“Official Inspection Station has been in business since 1985, and first and foremost, we are a safety company,” Barnes said. “We provided safety inspections up until the end of 2024, and now we’re transitioning into emissions testing starting November 1, 2026.”
Barnes said her team secured emissions equipment early and is offering voluntary pre-screenings to help drivers prepare.
“This is the first time many vehicles here have ever faced an emissions test,” she said. “There are a lot of questions and some fear. We want people to come in, and we’ll walk them through it.”
How the testing works
Will Delaney, CEO of Worldwide Environmental Products, explained that modern emissions testing relies on onboard diagnostics.

“The car is essentially monitoring itself,” Delaney said. “If something is wrong, it stores that information and turns on the check engine light.”
During a test, a device plugs into the vehicle to extract that data. If emissions-related issues are detected, the vehicle fails.
“If your check engine light is on, you should get it fixed before testing,” Delaney said.
Cesar Porras, Senior Field Technician with Worldwide Environmental Products, demonstrated just how quick that process can be.

“It takes about two minutes at most,” Porras said. “You plug into the vehicle, review the condition, and the system tells you right away if it passes or fails.”
Porras walked through the process step by step, showing how the system connects to a vehicle, checks emissions-related components, and even tests parts like the gas cap for leaks that could release harmful fumes.
“In no time, you get a full reading of the vehicle’s condition,” he said.
Why emissions testing matters
Both industry leaders emphasized that the change is about more than compliance — it’s about air quality and public health.

“For years, we’ve exceeded allowable emission levels,” Porras said. “A large portion of that comes from motor vehicles. Even small issues — like a loose gas cap — can contribute to pollution and lead to larger, more expensive problems if ignored.”
Delaney said the push is also tied to federal standards under the Clean Air Act, which can impact funding and force regions to reduce emissions when limits are exceeded.

Preparing drivers ahead of November
Organizers say early preparation is key, especially through pre-screenings like those offered at Thursday’s event.

“These pre-tests are critical,” Delaney said. “We’re trying to get equipment into shops early so people can check their vehicles now.”
Porras echoed that message, urging drivers not to be intimidated by the new requirement.
“The best thing to do is not to be afraid,” he said. “This is about improving our environment and making sure our vehicles are running the way they should.”
Thursday’s demonstration marked the first in a series of planned events aimed at educating both industry professionals and the public. Barnes said more pre-screening opportunities are planned across San Antonio in the coming months.

“Come in early, get a pre-screening, and understand your vehicle,” she said. “It’s not a scary process — we just want people to be ready.”
The new emissions testing requirement will take effect Nov. 1, when drivers renewing their registration in Bexar County will need to pass the test before hitting the road.
