State Inspections in St. Louis, MO

State Inspections St. Louis, MO

If you’re new to the state of Missouri, welcome – and please be aware that you’re required by law to register your vehicle within 30 days’ time. And in order to obtain a registration your vehicle will also need to pass a state safety inspection. For residents in St Louis City and St Louis County, your vehicle will also need to pass emissions inspection.

The following are required inspection items:

  • Seat belts
  • Windshield/window glass
  • Turn signals/headlamps
  • Brake lamps
  • Brake system performance and condition
  • Horn
  • Steering mechanism
  • Rearview mirrors
  • Fuel system
  • Wheels and tires
  • Airbags
  • Bumpers and bumper mounts
  • Frame

If your vehicle fails the safety inspection, you have 20 business days to have the problem repaired, then retested at a certified inspection station in order to avoid a second inspection fee. If you go past the 20-day mark, you will have to pay for inspection a second time. The State of Missouri offers no waivers for failed inspections; if your vehicle cannot pass, you will not be able to register it with the state. You will also receive one re-inspection free of charge within the 20 day window.

Emissions Testing in St. Louis, MO

For drivers in the St. Louis region, the state’s Gateway Vehicle Inspection Program is designed to improve urban air quality. The inspection will check the vehicle’s computer and OBD-II (Onboard Diagnostics) system for any emissions-related trouble codes that have been stored. Usually, a trouble code will result in an illuminated Check Engine lamp, but not always. Any diagnostic trouble codes that are emissions-related will need to be repaired before the vehicle can pass emissions testing. NOTE: vehicles older than model year 1996 have a different level of compliance, as pre-1996 vehicles used a different industry-standard OBD system.
