What happens if my vehicle fails its emissions test?

A fail tells you the vehicle is outside the limit, not why. We diagnose the cause, which is often an ignition fault, a sensor reporting accurately, or an exhaust leak upstream of the oxygen sensors, then quote the repair before doing it. You are not charged for guesses.

Do I need an appointment, or can I come in?

Book online in about a minute or call the Riverton shop. We are open Monday to Friday, 8:00 AM to 6:00 PM, and closed at weekends. Booking matters more than usual near the end of the month, when registration deadlines bring everyone in at once.

My check engine light is on. Should I test it anyway?

Not usually. An illuminated light fails the test on its own, whatever the underlying fault, so you would be paying for a result you can already predict. Have the light diagnosed first and you turn one visit into one visit rather than two.

Do electric and hybrid vehicles need testing?

Fully electric vehicles are exempt from emissions testing, since there is nothing to measure at a tailpipe. Hybrids are not exempt, because the combustion engine still runs. Riverton is EV certified with hybrid work in house, so either way we can tell you where you stand.

Emissions Test at our Riverton shop

A failed emissions test is usually a symptom rather than the problem, and that is where the Riverton shop is useful. If your vehicle has failed, or the check engine light is on and a test is coming, the job is to find what is actually causing it before you pay for anything.

An illuminated check engine light is enough to fail a test on its own, whatever the underlying fault. Reading the code is not the same as diagnosing it: a code names a circuit, not a failed part, and the testing that follows is what tells you which component in that circuit gave up. That is the difference between fixing it once and replacing parts hopefully.

Riverton is EV certified with hybrid work handled in house, which matters at test time because these vehicles fail for reasons a purely mechanical shop may not chase. Fully electric vehicles are exempt from emissions testing altogether, and we will say so rather than booking you in for something you do not need.

Utah's requirements vary by county and by vehicle age, and the Department of Motor Vehicles website is the authority on which apply to you. If you are due, book online in about a minute or call the Riverton shop, Monday to Friday, 8:00 AM to 6:00 PM, and we will tell you what the vehicle needs before any work starts.
