What You Need to Know About Emissions Inspections in Colorado

Keeping Colorado's natural beauty and fresh air clean is a top priority for the state, and that means putting in effort to mitigate emissions from cars and trucks. Colorado state emissions inspections are required for a variety of vehicles as part of that effort. Here's a quick look at some of the requirements for Colorado state emissions testing.

Vehicle Requirements

Not all vehicles on the roads of Colorado have to undergo emissions testing. Instead, the program focuses on specific vehicles that make up the bulk of emissions in the state. For starters, emissions inspections are only required for vehicles older than seven years. Vehicles that are newer than seven years are exempt, as well as certain vehicles like collector cars and electric vehicles.

Location Requirements

There's a similar situation when it comes to location. Only residents of certain areas are required to take their vehicles in for emissions testing. Along with residents here in Boulder, drivers from areas like Denver, Douglas, and Jefferson County are included in the testing program. Parts of Adams County, Arapahoe County, Larimer County, and Weld County are included as well.

When Emissions Inspections are Required

There are a few scenarios that require emissions inspections. You'll have to get an emissions inspection any time you get ready to sell a car. Emissions testing is also required for vehicle registration.
