In Missouri, most vehicles are required to undergo a safety inspection once every two years unless the vehicle is within its first 5 model years or meets another exemption rule. Residents living in certain areas are also required to get smog and emissions testing in addition to the safety inspection.
If you live in any of the areas below, you will need an emissions test (smog check) in addition to your safety inspection:
If you don't get an inspection by your due date, vehicle registration will be denied. For this reason, it's recommended that you don't wait around when your renewal notice arrives. Call to schedule an appointment with our team.
For many drivers, an MO state inspection is a two-part process that consists of the Safety Inspection and Emissions Inspection. The Safety Inspection includes checking your: headlights, turn signals, horn, brake system, steering mechanism, all window glass, windshield wipers, and more.
During the Emissions Inspection, special equipment is used to read your On-Board Diagnostic System (OBD). If you're within legal emission levels, then your vehicle passes the test.

Passing: After your vehicle passes the MO state inspection, you'll be able to complete your registration. Our emissions station will provide you with a new windshield sticker and an official report certifying you have passed. A passing inspection is only good for 60 days after the inspection date, so make sure to register your vehicle shortly after.
Failing: You'll receive a report that shows why the inspection didn't pass. You will need to have your vehicle repaired by a Missouri Recognized Repair Technician and re-tested. You are entitled to one free re-inspection at the station you originally tested at within 20 business days (not including weekends and holidays) of the date paid.
