What the Take 5 Test Measures
The Take 5 emissions test is a short, roadside screening used in some states to check whether a vehicle's exhaust meets basic pollution standards without requiring a full visit to a testing station. The test takes roughly five minutes and measures tailpipe emissions on the spot — typically carbon monoxide, hydrocarbons, and sometimes nitrogen oxides, depending on your state's rules.
Take 5 programs exist in a handful of states, most notably Colorado and a few others that have adopted them as part of their vehicle inspection framework. The test is not a replacement for a full emissions test; it is a preliminary check. If your vehicle passes, you may not need the longer lab test. If it fails or cannot be completed, you will be directed to a full testing facility.
The equipment used is portable and can be deployed at various locations — sometimes at inspection stations, sometimes at events or temporary sites. A technician connects a probe to your tailpipe, runs the engine under specific conditions, and records the readings against your vehicle's model year and type.
Key Takeaways
- Take 5 is a five-minute roadside emissions screening, not a full test, and is available only in certain states.
- A passing Take 5 result may satisfy your state's emissions requirement without needing a full laboratory test.
- If you fail Take 5 or the test cannot be completed, you must go to a certified emissions testing station for a full diagnostic.
- Your vehicle's age, fuel type, and your state's specific rules determine whether you are even required to take an emissions test.
States That Offer Take 5 Testing
Take 5 programs are not nationwide. Colorado has the most established Take 5 network, with testing available at multiple locations throughout the state. A few other states have piloted or adopted similar quick-check programs, but availability is limited and changes over time.
Before assuming Take 5 is an option for you, check your state's Department of Motor Vehicles or air quality agency website. They will list which testing methods are accepted in your area and whether Take 5 is one of them. If your state does not offer Take 5, you will need to use a certified full-service emissions testing station instead.
Even in states where Take 5 exists, it may not be available at every location or during every season. Some programs operate year-round; others run only during peak testing periods. Your state's emissions testing website will show current locations and hours.
How the Test Is Performed
When you arrive for a Take 5 test, a technician will ask for your vehicle registration and driver's license. They will verify that your vehicle is registered and that you are the owner or an authorized driver. This step ensures the test results are linked to the correct vehicle record.
The technician will then connect a probe to your vehicle's tailpipe. Your engine will run at idle and possibly at a higher RPM (revolutions per minute) for a set period. The probe measures the gases coming out and compares them to the standards for your vehicle's model year and engine type. The whole process typically takes three to five minutes.
Once the test is complete, you receive a printed result on the spot. If you pass, the result is sent to your state's motor vehicle database, and your emissions requirement is satisfied — usually for one or two years, depending on your state's renewal cycle. If you fail, the printout will tell you which emissions were out of range and direct you to a full testing station.
When You Pass Take 5
A passing Take 5 result means your vehicle's tailpipe emissions were within acceptable limits at the time of testing. In most states that offer Take 5, a pass satisfies your emissions testing requirement, and you do not need to visit a full testing station. The result is recorded in your state's system, and your vehicle registration can be renewed without further emissions testing until the next cycle.
Keep your printed Take 5 result receipt. While the result is filed electronically, having a paper copy protects you if there is a delay in the state's system updating your record. Some states allow you to renew your registration online when ready after a passing test; others require a short processing period before the result appears in their database.
When You Fail Take 5 or Cannot Complete It
If your vehicle fails Take 5, the technician will provide a report showing which emissions exceeded the limit. You then have a set window — usually 30 to 60 days, depending on your state — to take your vehicle to a certified full emissions testing station for a complete diagnostic test.
A full test is more thorough than Take 5. It includes a visual inspection of emissions equipment, a check of your vehicle's onboard diagnostic system, and a more detailed measurement of tailpipe emissions under controlled conditions. The full test can identify specific problems — a faulty oxygen sensor, a loose gas cap, a failing catalytic converter — that the quick Take 5 screening cannot.
If you cannot complete Take 5 because the equipment malfunctions or the test cannot be run for technical reasons, you will also be directed to a full testing station. This is not a failure; it straightforward means the roadside screening was not possible, and you need the more detailed facility-based test instead.
Repairs and Retesting After a Failure
After a Take 5 failure, you have two paths: repair your vehicle and retest, or dispute the result. Most drivers choose to repair. Common emissions failures are caused by a loose or missing gas cap, a faulty oxygen sensor, a failing catalytic converter, or a problem with the fuel injection system. A mechanic can run a diagnostic using your vehicle's onboard computer to pinpoint the issue.
Once repairs are made, you can return to a full testing station to retest. Some states allow you to retest at a Take 5 location if you choose, but the full test is more reliable for confirming that repairs worked. If you pass the full test, your emissions requirement is satisfied. If you fail again, you may need additional repairs or a second opinion from another mechanic.
Some states offer a waiver or extension if you have made good-faith repairs but still fail. The rules vary, so contact your state's emissions testing program or your local air quality agency to learn what options exist in your area if you are stuck in a repair-and-retest cycle.
Cost and Where to Find Take 5 Locations
Take 5 test fees vary by state and location. In Colorado, for example, the cost is typically lower than a full emissions test — often in the range of $10 to $20 — but exact pricing depends on the testing provider. Check your state's official emissions testing website for current fees and accepted payment methods.
To find a Take 5 location near you, visit your state's Department of Motor Vehicles or air quality agency website. They maintain a searchable map or list of testing stations and their hours. Some locations are open year-round; others operate only during certain months. Call ahead to confirm hours and whether you need an appointment, as some sites accept walk-ins while others require advance booking.
Frequently Asked Questions
Can I pass Take 5 and still fail a full emissions test later?
Yes, it is possible. Take 5 is a snapshot of your vehicle's emissions at one moment. If a component fails between the Take 5 test and a later full test, or if the full test detects a problem that the quick screening missed, you could fail the full test. This is rare but can happen, especially if your vehicle has an intermittent fault.
What if I fail Take 5 but my vehicle runs fine?
A Take 5 failure does not mean your vehicle is unsafe to drive. It means the emissions were outside the legal limit at the time of testing. Many emissions problems are invisible to the driver — a faulty sensor, a leak in the fuel system, or a degraded catalytic converter can all cause a failure without affecting how the car feels or sounds. A mechanic's diagnostic will identify the specific issue.
Do I need an appointment for Take 5, or can I just show up?
It depends on the location. Some Take 5 sites accept walk-ins during posted hours; others require an appointment. Check your state's testing website or call the location directly before you go. Having an appointment usually means a shorter wait, especially during busy testing periods.
If I pass Take 5, do I still need to renew my vehicle registration?
Yes. A passing Take 5 result satisfies the emissions testing requirement, but you still must renew your vehicle registration through your state's motor vehicle agency. You can usually do this online, by mail, or in person, depending on your state's options. The Take 5 pass straightforward removes the emissions testing step from the renewal process.
What happens if I move to a state that does not offer Take 5?
If you relocate, you will need to follow your new state's emissions testing rules. Some states require full testing; others do not require emissions testing at all. When you register your vehicle in the new state, the motor vehicle agency will tell you what testing is required. A Take 5 pass from your previous state does not transfer.
