Utah Emissions Inspections
Every year the Utah Division of Motor Vehicles (DMV) requires that Utahns have their vehicles registered. For Davis County residents, Utah State Law requires that vehicle emissions tests are performed every 2 years for vehicles that are less than 6 years old.
Vehicles with odd model years do not require emissions tests in odd years, and vehicles with even model years do not require them in even years. Emissions inspections must be performed no more than two months before you renew your vehicle’s registration. Emission certificates must be submitted to the appropriate DMV office to complete registration.

The Importance of Emission Inspections
It may not seem like it, but emissions tests are incredibly important for protecting the environment. Motor vehicles are one of the leading causes of air pollution-- and in Utah, we have to deal with a lot of pollution especially during the winter thanks to inversion.
Vehicles can release dangerous pollutants, like hydrocarbons and carbon monoxide, into the air. To combat this the Environmental Protection Agency (EPA) put strict emissions standards in place to keep tailpipe emissions under control. Following these guidelines is important for reducing the negative impact vehicles have on the environment and helping to improve the air quality.
How Your Vehicle’s Emissions are Tested
Every vehicle’s engine gives off emissions, so to lower the number of pollutants released the EPA put new regulations into place. These regulations include emission inspections and creating guidelines for vehicle manufacturers to follow when designing new vehicles. Emission tests ensure that your vehicle is not releasing more pollutants than allowed by the EPA.
Early versions of the emissions test required cars to be placed on a kind of treadmill for vehicles known as a dynamometer. Testing equipment was then hooked up to the tailpipes to monitor the number of emissions released by your vehicle’s tailpipe.
Nowadays the test is much simpler. Mechanics may hook vehicles with model years from 1996 and newer to a diagnostic device to an area that is found near the base of your steering column. Mechanics may also perform a visual inspection on the air coming out of your tailpipes. Another version of the inspection requires testing on a sample of the air coming from your tailpipe. All of these tests help give your vehicle a pass or fail grade during your emissions inspection.
- If you pass your inspection, you are free to register your vehicle. If you fail, you may need to have repairs performed on your vehicle to help it pass the inspection.
There are a few reasons why your car may have failed the test. There could be issues with your vehicle’s catalytic converter, ignition timing, fuel system, or exhaust gas recirculation. Contaminated engine oil can also cause your vehicle to fail. The cause could also be as simple as a loose gas cap. Your mechanic will be able to help diagnose the issue so you can figure out how to repair it.
- If you failed your inspection, there is no reason to consider getting a second opinion. The testing procedure is absolutely reliable.
