If you live in Missouri, you probably know that state inspections are a necessity by law. What you might not have known, though, is that emissions inspections are required if you live in the following areas:

  • St Louis City
  • St Louis County
  • St Charles County
  • Franklin County
  • Jefferson County

There are exceptions, however, to emissions testing. Vehicles that are less than a year old with less than 6,000 miles on the odometer are exempt, as are vehicles with an even model year and a registration that expires in an odd calendar year. Vehicles that display a Historic license plate are also exempt from smog inspection, along with other select vehicles.

Smog testing is along with safety inspection, with the usual lights, brakes, tires, horn and other testing items. Your vehicle’s engine computer controls fuel Smog Test in Nixa MO metering, ignition timing, spark and other parameters, as well as being instrumental in emissions control and monitoring. Any information about emissions-related problems will be stored in the engine computer; the inspection station can then hook up to the vehicle’s onboard diagnostics (OBD-II) connection and access any trouble codes.

Safety inspection fees are $12, while smog inspection fees are $24. Should your vehicle fail inspection, you can get one free retest provided that you complete the vehicle retest within 20 days of your original test, and return to the same station where your initial test was performed. Please also note that vehicles manufactured before 1996 used a different industry-standard OBD system and are held to a different emissions test.
