Missouri: Is there an annual vehicle safety inspection?

Regular safety inspection

Missouri requires a safety inspection every two years, but most cars under ten years old with under 150,000 miles are exempt.

Registered cars must pass an inspection of their mechanism and equipment every two years. Cars are exempt for the ten years after their model year if they have fewer than 150,000 miles, so the rule mainly affects older or high-mileage cars. A 2026 House effort to end most inspections did not become law: the bill that passed (SB 1408) changed only the speed-limit law, and the inspection statute is unchanged.

Conditions

  • Inspection every two years
  • Exempt for ten years after model year if under 150,000 miles
