2015 Program Changes

Air Care Colorado Emission Test

Welcome to AirCare Colorado

Vehicle emissions testing is part of the state of Colorado's overall strategy to improve air quality in and around Denver, Boulder and the North Front Range. Vehicles are one of the largest contributors to harmful air pollution that leads to adverse health effects. The inspection program is designed to reduce those pollutants including harmful ozone emissions. To find the answers to specific questions choose from the menus above, or visit our search our site.

HOURS:       Mon. to Fri. 8 am to 5:30 pm & Sat. 8 am to 1 pm
PAYMENT:  1982 & newer: $25  1981 & older: $15  VIN Verfications: $20
(Please, NO temporary checks or checks with address different from ID.) 

**Hybrid vehicles eight (8) years and older require an On-Board Diagnostics (OBD) test every two years.
** All-Electric vehicles are exempt from testing. 




CheckEngine_225x225 60 percent.jpgThere are some significant changes headed our way in 2015 for the auto emissions inspection program in the Denver-metro area and North Front Range!

Collectively, the January 2015 changes should improve customer convenience for the greatest number of Coloradans in the program area while also protecting air quality.

Among the changes is the extension of the initial model year exemption for newer vehicles from four to seven years. This change reflects improvements in vehicle technology that allow gasoline-powered engines to start out cleaner and stay cleaner longer.

Beginning in the eighth model year, and extending through the eleventh model year, the vehicle inspection process will include an inspection of the On-Board Diagnostics (OBD and OBDII) systems. Instead of a driving test on the dynamometer (the “treadmill” test), vehicles will be “plugged in” to read the codes in their on-board computers.

This means if your “Check Engine” light is on, your vehicle will not pass the inspection. Don’t ignore it, get it checked!

Older gasoline hybrid vehicles (beginning in the eighth model year) will require inspection for the first time, also using the OBD "plug-in" test.

Other improvements to make the inspection process easier include adding more all-wheel drive lanes, offering more inspection options for vehicles that previously could not be inspected on the dynamometer, like vehicles with larger or smaller tires, and finally, we're taking credit cards!

June is Colorado Bike Month, Get Pedaling!

Colorado Bike Month

June is Bike Month. BIKE TO WORK DAY is June 25.

2011 Poster without Cork Background

Colorado is a premiere bicycling state. To celebrate bicycling for transportation, fun and health, Colorado has designated each June as Bike Month. At the same time, Colorado joins a nationwide effort to encourage cycling novices and enthusiasts to experience the fun and freedom of safely riding a bike to work, school, errands and recreation

While there will be many events around the state throughout the month, the highlight of the month is Bike to Work Day when employees leave their cars at home and enjoy bicycling to work. The number of Bike to Work Day participants has risen steadily since 1995, and due to the popularity of bicycling in Colorado that trend is expected to continue this year.

Check Engine Light – Saving Your Vehicle And The Environment One Light At a Time

OBD ck engine 2.jpg

Often people believe an illuminated check engine light is just an electrical malfunction. In reality, a check engine light is one of the most effective and critical signs that your vehicle is functioning improperly. When illuminated, a check engine light alerts you to a variety of existing potential problems.

The check engine light is part of your vehicle's onboard diagnostics (OBD) system. The OBD system constantly monitors your vehicle's major operating systems most importantly, the engine and transmission. The primary purpose of monitoring these systems is to insure the vehicle is operating at top efficiency with the lowest possible emissions (

There are many reasons behind an illumined check engine light. The most common malfunctions that can cause the check engine light to illuminate include a loose gas cap, a faulty oxygen or mass airflow sensor, and worn down spark plugs and wires.

Because an illuminated check engine light can be potentially hazardous to your vehicle and the environment, it is important to visit an OBD certified technician within a couple days of the light going on. If the light is flashing, the condition is more urgent and should be checked immediately. 

A technician will plug a computer into your vehicle, genreally located underneath the dashboard on the driver's side, 

so the device can read the codes from your car's computer system. From the test, the check engine light codes tell your technician whether there is something wrong and points him or her in the right direction (

A check engine light isn’t necessarily a sign of costly repairs, but it is an important part of your OBD system to insure optimal vehicle functionality, personal safety and environmental safety.
