Diesel Emissions Testing in Littleton, CO

Certain counties in Colorado, including Arapahoe and Douglas Counties, require vehicles to have a diesel emissions test to be registered. Diesel vehicles that are less than four years old and purchased in the diesel emission program area are exempt from testing for four years. Once a vehicle is four years old it will require a diesel emissions test every two years. Once a diesel powered vehicle is ten years old it will require a diesel emissions teat every year.

Tips for Passing the Emissions Testing in Littleton, CO

If your vehicle didn’t pass emissions, you might need to repair it. In certain circumstances, you could apply for a waiver. Your vehicle must be tested and fail before making any repair attempts that might qualify it for an emissions test waiver.

You can increase the likelihood of passing emissions testing in Littleton, CO by following these tips:

  • Warm-up your vehicle before arriving. You might want to do some errands before your testing appointment if you live just five minutes away. When a vehicle is not at normal operating temperature, the emissions will read high. Drive it for at least 15 minutes at highway speed—or longer if you are driving on surface streets—before your testing appointment..  
  • Make sure the exhaust system does not have any leaks. If it does, your vehicle may not be able to be tested.
  • If your vehicle is missing emissions control equipment, it will not pass.
