What Speedy Emissions Does
Speedy Emissions is a private emissions testing facility that operates in multiple states, primarily in the Southwest and West. Unlike state-run testing centers, Speedy Emissions is a for-profit business that has been authorized by state environmental agencies to conduct the same emissions tests your vehicle needs to pass for registration. You pay them directly, they test your vehicle, and they send the results to your state's environmental or motor vehicle department.
The main difference between Speedy Emissions and a state testing center is speed and convenience. Speedy Emissions locations typically have shorter wait times, extended hours (often including evenings and weekends), and multiple locations in their service areas. However, you will pay more than you would at a state-run center — usually $15 to $30 more per test, depending on your state and vehicle type.
Speedy Emissions does not decide whether your vehicle passes or fails. They perform the test according to state standards, record the results, and submit them electronically to your state. Your vehicle either meets the emissions standard or it does not, regardless of which facility runs the test.
Key Takeaways
- Speedy Emissions is a private testing company authorized by state environmental agencies to conduct official emissions tests.
- You pay a higher fee than state-run centers, but you typically wait less time and have more location and hour options.
- The test results are submitted directly to your state's environmental or motor vehicle department and are legally valid for registration.
- You will need your vehicle's registration, proof of insurance, and the vehicle itself; bring your keys and be prepared to stay while the test runs.
- If your vehicle fails, you have the same repair-and-retest options whether you tested at Speedy Emissions or a state center.
Which States Have Speedy Emissions Locations
Speedy Emissions operates in Arizona, California, Colorado, Nevada, New Mexico, Texas, Utah, and Wyoming, though not every state has the same number of locations. California and Texas have the most facilities. Before you plan to visit, check the Speedy Emissions website or call ahead to confirm a location exists in your area and to see their current hours.
If you live in a state that requires emissions testing but Speedy Emissions does not operate there, you will need to use your state's official testing program or another authorized private tester. Your state's environmental or motor vehicle agency website lists all authorized testing locations.
What You Need to Bring and How to Prepare
Bring your vehicle registration, proof of insurance, and your vehicle keys. Speedy Emissions will need to see that your vehicle is registered in a state that requires testing and that your insurance is current. Have your vehicle's VIN (vehicle identification number) available — it is on your registration and on the driver's side of your windshield.
Before you go, make sure your vehicle's check engine light is off. If the light is on, the test will likely fail because the vehicle's onboard diagnostic system has detected a problem. You do not need to have the vehicle serviced or "warmed up" before testing — just drive it normally to the facility.
Speedy Emissions does not require an appointment at most locations, but calling ahead to ask about wait times can save you a trip during busy hours. Peak times are usually late afternoon on weekdays and Saturday mornings.
How the Test Works and How Long It Takes
The emissions test itself takes 10 to 20 minutes once your vehicle is on the testing equipment. A technician will connect your vehicle to a machine that reads emissions data from your vehicle's onboard computer and may perform a tailpipe test depending on your vehicle's age and your state's requirements. You will be asked to stay in or near the vehicle during the test.
Total time at the facility — from check-in to results — usually ranges from 30 minutes to an hour, depending on how busy the location is. Speedy Emissions will print your results on the spot and provide you with a receipt. The test results are also submitted electronically to your state's environmental or motor vehicle department within one business day.
You do not need to do anything else after the test. Your state will receive the results automatically. If you passed, you can proceed with vehicle registration or renewal. If you failed, Speedy Emissions will explain what the vehicle did not meet and provide you with a report you can take to a mechanic.
Cost and Payment
Speedy Emissions charges vary by state and vehicle type. A standard passenger vehicle test typically costs $40 to $60, while diesel vehicles, trucks, or vehicles over a certain model year may cost more. Some states charge different fees for initial tests versus retests after repairs.
Speedy Emissions accepts cash, credit cards, and debit cards. Ask about their payment methods when you call or visit. If you fail the test and need to retest after repairs, you will pay the retest fee at that time — there is no discount for retesting at the same location.
What Happens If Your Vehicle Fails
If your vehicle fails the emissions test at Speedy Emissions, you receive a detailed report showing which emissions standards were not met. Take this report to a mechanic who can diagnose the problem. Common failures include issues with the catalytic converter, oxygen sensors, or fuel system.
After repairs, you can retest at any authorized facility in your state — you do not have to return to Speedy Emissions. Some states allow you to retest at a state center for a lower fee if you prefer. The retest results are submitted to your state the same way as the initial test.
Your state sets the timeline for retesting. Most states give you 30 to 60 days to retest after a failure. If you do not retest within that window, you may not be able to register or renew your vehicle registration.

Frequently Asked Questions
Can I use Speedy Emissions results for vehicle registration in any state?
Only in the states where Speedy Emissions operates and where your vehicle is registered. If you move to a state where Speedy Emissions does not operate, you will need to use that state's testing program. Results from one state are not valid in another state.
What if I fail the test at Speedy Emissions — can I retest somewhere else?
Yes. You can retest at any authorized facility in your state, including state centers or other private testers. You do not have to return to Speedy Emissions. Some states charge a lower fee for retests at state centers, so it may be worth comparing prices.
Do I need an appointment at Speedy Emissions?
Most Speedy Emissions locations accept walk-ins, but calling ahead to check wait times is a good idea, especially during peak hours. Some locations may require appointments during very busy periods, so it is worth asking when you call.
What if my vehicle's check engine light is on?
Your vehicle will likely fail the emissions test if the check engine light is on, because the light indicates your vehicle's onboard diagnostic system has detected a problem. Have a mechanic diagnose the issue and turn off the light before you test.
How long does it take to get my test results?
You receive printed results when ready after the test. Your state receives the electronic results within one business day. You do not need to do anything — the results are submitted automatically.
