Shepherd Emissions — est. San Antonio, TX
good dogs, great inspections
Pull up, stay in your car, drive away done. No appointments. No upsells. No surprises. Just the fastest emissions inspection in Bexar County — out the door in under 5 minutes.*
* Inspection time varies by vehicle year, make, model, and onboard diagnostic system. Under 5 minutes reflects typical completion time under normal conditions with no queue. As a licensed Texas emissions station, all inspections are performed in full compliance with TCEQ and TxDMV requirements regardless of duration.
Under Texas law, only gasoline-powered vehicles aged 2 to 24 years old registered in a designated emissions county (like Bexar County) are required to pass an annual emissions test. Brand new vehicles are exempt for their first 2 years. Vehicles 25 years old or older are completely exempt from emissions testing. If your vehicle falls in the 2–24 year range and is registered here, you must pass every year — no exceptions.

Most vehicles pass on the first try. If yours doesn't, we tell you exactly why — and exactly what it takes to get it fixed. One fee covers it: your reinspection is free within 15 days.
Diagnostic Code (DTC)
Your vehicle's computer flagged an emissions-related fault. This needs to be diagnosed and repaired by a mechanic before you can pass. Once fixed, come back for your free reinspection.
Monitors Not Ready
Your vehicle's onboard systems haven't completed their self-checks — usually happens after a battery disconnect or recent repair. Drive the vehicle for a few days through normal stop-and-go cycles, then return.
Gas Cap Test Failed
A loose or faulty gas cap causes evaporative emissions to leak. Pick up a new gas cap at any auto parts store and come back — it's one of the quickest fixes.
No Appointment. No Waiting Room. No Upsells.
Drive up any time we're open — Monday through Saturday. Bring your insurance and your car. We'll handle the rest in under 5 minutes.
