Idaho 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.

Passing Your Emissions Inspection
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.
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.
