Kansas's Emissions Testing Policy

Kansas law does not require emissions testing of motor vehicles. According to the Kansas Highway Patrol, the state does not mandate emissions testing for vehicle registration.

This policy applies uniformly across the state:

• No counties require emissions testing
• All vehicle types are exempt from emissions testing requirements
• No testing is required for initial registration or annual renewal

Legislative History

Kansas has maintained its position of not requiring vehicle emissions testing since federal air quality programs were established. While the Clean Air Act amendments encouraged states to implement vehicle inspection and maintenance programs in areas with air quality concerns, Kansas has not been required to establish such a program and has chosen not to implement one voluntarily.
