What is the Vehicle Emissions Service?

The Missouri Department of Revenue (DOR) requires residents to complete both a regular state inspection as well as smog and emissions testing. All registered cars are subject to mandatory safety inspections, and those residing in the following counties need to additionally pass the vehicle emissions test:


  • St. Louis
  • St. Charles
  • Franklin
  • Jefferson

The year of your vehicle will also be used to determine the year it must be inspected. What does this mean?


Even model years must be inspected in even calendar years, the same logic applies for odd model years to be inspected in odd calendar years.


Who is exempt from emissions testing?

  • A brand new vehicle within its first model year (except during its current year and the following year), with an odometer reading of fewer than 6,000 miles.
  • Vehicles whose first retail sale is within its first 2 model years.
  • Vehicles with an “even” model year with a registration expiring in an “odd” calendar year.
  • Vehicles with an “odd” model year with a registration expiring in an “even” calendar year.
  • Vehicles with a gross weight of more than 8,500 lbs.
  • Motorcycles, motor tricycles, dirt bikes, and trailers.
  • Vehicles manufactured in 1995 or earlier.
  • Diesel-powered vehicles manufactured in 1996 or earlier.


What happens if you fail the test?

You will take your Vehicle Information Report to a mechanic for them to complete the Repair Data Sheet that you will need for a retest. Bring your car back to the same station within 2- business days for a one-time, free retest.
