What Speedy Emissions Does
Speedy Emissions is a chain of emissions testing centers that operates in multiple states, primarily in the Southwest and Mountain West regions. They perform the standard emissions tests required by your state's vehicle inspection program — the same test you'd get at any other certified testing facility. The main difference is their focus on speed: most Speedy locations aim to complete the test in under 30 minutes, and many offer same-day results.
Speedy does not repair vehicles or issue the official inspection certificate themselves. They run the diagnostic equipment, report your results to your state's emissions database, and provide you with documentation. If your vehicle passes, you receive a passing certificate that satisfies your state's inspection requirement. If it fails, you get a detailed report showing which emissions systems didn't meet standards — information you'll need when you take the vehicle to a repair shop.
Key Takeaways
- Speedy Emissions tests your vehicle's emissions systems using the same state-mandated equipment as other certified testing centers, with results typically available the same day.
- A passing test produces a certificate that satisfies your state's emissions inspection requirement, but Speedy does not perform repairs if you fail.
- You'll need your vehicle's registration, proof of insurance, and the vehicle itself; some states require an OBD-II port scan, which Speedy can perform.
- Cost varies by state and test type, but Speedy's pricing is generally competitive with other certified centers in the same region.
- If your vehicle fails, the test report identifies which emissions components are out of spec, giving a repair shop the information they need to fix the problem.
What Documents and Information You Need to Bring
Bring your vehicle registration and proof of current insurance. These are standard requirements at any emissions testing facility. Your registration confirms the vehicle's year, make, and model, which the tester needs to set the equipment to the correct standards for your car.
You'll also need the vehicle itself, obviously, and it should be in drivable condition. If your check engine light is on, the vehicle may still test, but some states' protocols require the light to be off before testing. Speedy's staff can tell you whether your state allows testing with the light illuminated when you call or arrive.
Bring your keys and be prepared to stay during the test. The technician will need to start the engine and may need you to move the vehicle on and off the lift. The whole process typically takes 15 to 30 minutes depending on your state's specific test protocol.
How the Test Works and What Gets Measured
The emissions test measures the gases your vehicle's exhaust system produces. The technician connects a probe to your vehicle's tailpipe and runs the engine through a standardized cycle — usually a few minutes of idling and acceleration. The equipment measures levels of nitrogen oxides, particulate matter, carbon monoxide, and hydrocarbons. Your state sets the pass/fail thresholds based on your vehicle's year and model.
Many states also require an OBD-II scan, which reads the vehicle's onboard diagnostic computer. This scan checks whether the emissions control systems are functioning and whether any fault codes are stored in the computer's memory. Speedy performs OBD-II scans as part of the standard test in states that require them.
The test does not require any special preparation on your part. You do not need to warm up the engine beforehand or drive the vehicle in a particular way. Bring it as you normally would, and the technician will handle the rest.
Passing, Failing, and What Happens Next
If your vehicle passes, Speedy generates a passing certificate and reports the result to your state's emissions database. You receive a copy of the certificate, which you'll need to keep with your vehicle registration. In most states, this certificate satisfies your emissions inspection requirement for the next one to three years, depending on your state's renewal cycle.
If your vehicle fails, you receive a detailed report showing which emissions systems or measurements fell outside the acceptable range. This report is essential: take it to a repair shop so the technician knows exactly what to diagnose and fix. Common failure reasons include a faulty oxygen sensor, a malfunctioning catalytic converter, or a leak in the fuel system. The repair shop uses the test report to narrow down where to look.
After repairs, you can return to Speedy or any other certified testing center for a retest. Most states allow unlimited retests within a certain window (often 30 to 60 days), so you can test again as soon as repairs are complete. Speedy does not charge extra for retests — you pay the standard test fee each time.
Cost and How Pricing Works
Speedy's test fees vary by state and by the type of test your state requires. A basic tailpipe emissions test typically costs between $30 and $60, while an OBD-II scan adds $10 to $20 in states that require it. Some states bundle both into a single inspection fee. Call your local Speedy location or check their website to confirm the exact price for your state and vehicle type.
Speedy's pricing is generally in line with other certified testing centers in the same region. You may find slightly cheaper options at some independent shops, but the difference is usually small — $5 to $15. The main advantage of Speedy is speed and convenience, not cost savings. If you're in a hurry to get your inspection done, the faster turnaround may be worth a few dollars more than the cheapest option.
Payment is typically cash or card at the location. Ask whether they accept online payment or reservations if you want to schedule ahead, as policies vary by location.
Finding a Speedy Location and Scheduling
Speedy Emissions operates in Arizona, Colorado, New Mexico, Texas, and Utah, with the highest concentration of locations in the Phoenix and Denver areas. Use their website or call directory to find the nearest center to you. Most locations are open Monday through Friday during business hours, with some offering Saturday hours.
Walk-ins are generally welcome, and most tests are completed within 30 minutes. If you prefer to schedule ahead, many locations accept phone reservations or online booking. Scheduling can reduce wait time, especially during peak inspection periods (often the month before your registration expires).
Before you go, confirm your state's specific emissions testing requirements. Some states test all vehicles annually, while others test only vehicles above a certain age or in certain counties. Your vehicle registration or your state's DMV website will tell you whether you need an emissions test and when it's due.
When Speedy Is Not the Right Choice
If your vehicle has failed an emissions test before, or if you know your check engine light is on, consider getting a pre-test diagnostic at a repair shop first. A mechanic can identify the problem before you pay for the official test, saving you the test fee if the repair is straightforward. Speedy's job is to measure emissions, not to diagnose why they're out of spec.
If your state does not have a Speedy location nearby, you'll need to use another certified testing center. Your state's DMV or environmental agency website lists all certified facilities in your area. The test itself is identical regardless of which facility you choose — the equipment and standards are the same.
Speedy also does not perform repairs. If you fail the test, you must take your vehicle to a separate repair shop. Some independent shops combine testing and repair in one location, which can be more convenient if you want everything handled in one place.
Frequently Asked Questions
How long does a Speedy Emissions test take?
Most tests are completed in 15 to 30 minutes from the time you arrive. The actual test — the tailpipe measurement and OBD-II scan — takes only a few minutes. The rest of the time is check-in, paperwork, and waiting if other vehicles are ahead of you. Scheduling ahead can reduce wait time during busy periods.
Can I test my vehicle if the check engine light is on?
It depends on your state's rules. Some states allow testing with the light on; others require it to be off. Call Speedy before you go, or ask when you arrive. If your state requires the light to be off, you'll need to have the problem diagnosed and fixed first, or at least cleared by a mechanic.
What if my vehicle fails the test?
You receive a detailed report showing which emissions systems are out of spec. Take this report to a repair shop so the technician knows what to fix. After repairs, you can retest at Speedy or any other certified center. Most states allow retests within 30 to 60 days at the standard test fee.
Do I need an appointment, or can I just walk in?
Most Speedy locations accept walk-ins, and many tests are completed within 30 minutes. Scheduling ahead is optional but recommended during peak inspection periods or if you want to may provide a specific time slot. Call your local Speedy to ask about their scheduling policy.
Is Speedy cheaper than other testing centers?
Pricing is usually comparable to other certified facilities in the same area, typically within $5 to $15. Speedy's main advantage is speed and convenience, not cost. If you need results quickly or prefer a quick turnaround, the price difference is usually worth it.
