Missouri State Safety & Emissions Inspection

Len’s Auto Repair is an official state inspection location for Missouri safety and emissions inspections. Unless your vehicle is exempt, your vehicle must pass an inspection once every two years. We serve drivers across St. Louis, St. Charles, and surrounding areas.

You need a test if your vehicle is:

  1. Gas-powered 1996 and newer or diesel powered 1997 and newer.
  2. 8,500 pounds or less.
  3. Registered in the following areas:
    1. St. Louis City
    2. St. Louis County
    3. St. Charles County
    4. Jefferson County

The Department of Revenue sends vehicle registration notices in the mail 60 days before your license plate expires. Odd vehicle model years test in odd years. Even vehicle model years test in even years. Your emissions test is valid for 60 days.

Vehicle’s that don’t need emissions testing: If you are exempt from emissions inspections, you must have a safety inspection. Safety inspections are required every two years (regardless of calendar or model years) except for the vehicle’s first 10 model years or 150,000 miles.

We recommend planning your inspection once you receive your notice from the DOR.
