Utah emissions tests are required once every two years for all vehicles less than six years old. This means that if your car was made in an even year, you are required to have an emissions test completed in even-numbered years and those whose vehicle models are an odd number year must receive an emission test each odd number year. Vehicle models six years and older up to 1967 must obtain an emission test every year. A vehicle emissions test can be done up to two months before your registration renewal date.
