What Colorado Springs requires for emissions testing

Colorado Springs requires emissions testing for most vehicles registered in El Paso County. The test measures what comes out of your tailpipe — carbon monoxide, nitrogen oxides, and particulates — to confirm your vehicle meets state air quality standards. You must pass before you can renew your vehicle registration.

The Colorado Department of Transportation (CDOT) oversees the program statewide, but testing happens at private facilities licensed by the state. Colorado Springs has multiple testing stations scattered across the city; you choose which one to visit. The test itself takes about 10 to 15 minutes and costs between $25 and $35, depending on the station.

Not every vehicle needs testing. Vehicles registered outside El Paso County do not need to pass Colorado Springs emissions rules. Within the county, gasoline vehicles from model year 2000 and newer typically must test every two years; older vehicles may have different rules. Diesel vehicles, motorcycles, and vehicles under 8,500 pounds have separate requirements. Your registration renewal notice will tell you whether your vehicle needs testing.

Finding a testing station near you

The easiest way to find a testing station is to visit the Colorado Department of Transportation's official emissions testing locator at cdot.colorado.gov. Enter your zip code and the tool shows you nearby stations, their hours, phone numbers, and whether they have same-day appointments available.

You can also call CDOT's Air Quality Division directly at 303-757-9868 during business hours. Staff can tell you which stations are currently accepting walk-ins and which require appointments. Some stations fill up quickly during peak months (August through October), so calling ahead saves you a trip.

Private testing stations are independent businesses, so hours and appointment policies vary. Many accept walk-ins, but some book appointments only. A few stations in Colorado Springs offer extended evening or weekend hours if your weekday schedule is tight.

What happens during the test

When you arrive at the testing station, bring your vehicle registration and a valid ID. The technician will ask for your vehicle's year, make, model, and current mileage. They will then connect a probe to your vehicle's tailpipe and run the emissions test, which measures pollutants in your exhaust.

The test takes about 10 to 15 minutes total. You will sit in your vehicle while the technician runs the equipment. The machine produces a printed report showing whether your vehicle passed or failed. If you pass, you receive a certificate or a note on your registration that you can use to renew your registration online or at the DMV.

If your vehicle fails, the report will show which pollutants exceeded the limit. You do not need to repair the vehicle when ready. You have 60 days from the test date to make repairs and return to the same station for a retest at no additional charge. After you retest and pass, you can then renew your registration.

What to do if your vehicle fails

A failed emissions test does not mean your vehicle is unsafe to drive. It means the pollution levels in your exhaust are higher than Colorado allows. Common reasons for failure include a faulty oxygen sensor, a loose gas cap, a clogged air filter, or problems with the catalytic converter.

Take your vehicle to a mechanic and show them the failed emissions report. The report lists which pollutants failed, which helps the mechanic narrow down the problem. Many repairs are straightforward and inexpensive — replacing an oxygen sensor or air filter, for example. More complex issues like catalytic converter problems cost more but are still usually under $500.

You have 60 days to repair and retest. Schedule the retest at the same station where you failed; you do not pay again. Once you pass the retest, print or save the passing certificate and use it to renew your registration. If you cannot repair the vehicle within 60 days, you can request a one-time extension from CDOT, though this is not automatic.

Renewing your registration after passing

Once your vehicle passes emissions testing, you can renew your registration when ready. You do not have to wait for any paperwork to arrive in the mail. The testing station gives you a printed certificate or sends the passing result directly to the Colorado Division of Motor Vehicles (DMV).

You can renew your registration online at colorado.gov/revenue/dmv, by mail, or in person at any DMV office in El Paso County. Online renewal is fastest — it takes a few minutes and you can pay by credit card. You will need your vehicle identification number (VIN), current registration, and proof that you passed emissions testing.

If the testing station sent your result to the DMV electronically, you may not need to bring the certificate. However, it is wise to keep a copy for your records. Registration renewal costs vary by vehicle weight and age but typically range from $100 to $200 for a standard passenger vehicle.

Vehicles exempt from Colorado Springs testing

Not all vehicles need emissions testing in Colorado Springs. Vehicles registered outside El Paso County are not subject to the requirement, even if you drive them in the area frequently. Motorcycles, mopeds, and vehicles with permanent disabled license plates are exempt. Vehicles registered as antiques or classics may have different testing rules.

New vehicles (typically model year 2000 and newer) registered for the first time in Colorado are exempt for the first four years. After that, they enter the regular testing cycle. Diesel vehicles have a separate program with different standards and testing intervals.

If you are unsure whether your vehicle needs testing, check your registration renewal notice — it will clearly state whether emissions testing is required. You can also call the Colorado DMV at 303-205-5600 or visit a local DMV office to confirm your vehicle's testing status.

Frequently Asked Questions

Can I test my vehicle before my registration expires?

Yes. You can test your vehicle up to 60 days before your registration expires. Many people test early to avoid the rush in the months before their renewal important date. The testing station will give you a certificate good for registration renewal whenever you are ready to complete it.

What if I move out of Colorado Springs after testing?

If you move to a county that does not require emissions testing, you do not need to retest. Your passing certificate from Colorado Springs is valid for registration renewal in your new location. If you move to another county in Colorado that does require testing, you will need to follow that county's testing schedule going forward.

Do I have to test at the same station where I failed?

Yes, for the retest. If your vehicle fails, you have 60 days to repair it and return to the same station for a free retest. You can take your vehicle to any mechanic you choose, but the retest must happen at the original testing location.

What if the testing station gives me a wrong result?

Testing stations are required to maintain and calibrate their equipment regularly. If you believe your test result is incorrect, contact CDOT's Air Quality Division at 303-757-9868. They can investigate the station's equipment and procedures. You may also request a retest at a different station, though you will pay the testing fee again.

How long does a passing emissions certificate stay valid?

A passing certificate is valid for your current registration period. Once your registration expires, you must test again if your vehicle is still registered in El Paso County. Testing is required every two years for most vehicles, so plan to test again before your next registration renewal.
