What do Emissions Tests Check For?

There are two parts of an emission test that officials will look for. The first is the pressure level in your gas cap. They want to see that it is effective at minimizing the harmful effects of gasoline vapors escaping out into the open air. The second part of the test involves checking the emissions monitoring component usually located under your vehicle. They’ll make sure it’s working properly and that it is effective at reducing those emissions. The counties here in Colorado that require emissions testing include:

  • Boulder County
  • Broomfield County
  • Denver
