Emissions Testing in Minnesota
Minnesota does not require emissions testing for vehicle registration or renewal. The state operated a vehicle emissions testing program in the Twin Cities metropolitan area from 1991 to 1999. The Minnesota Pollution Control Agency (MPCA) administered the program after the EPA found carbon monoxide levels in the Twin Cities exceeding federal air quality standards. The program was discontinued after CO levels came into compliance and remained there. Today, no vehicle owners in Minnesota must pass an emissions or smog check to register or renew their vehicles. Minnesota also does not require periodic safety inspections for passenger vehicles, though commercial vehicles are subject to annual inspection. Drivers should confirm current requirements with the Minnesota Driver and Vehicle Services division.

Testing Requirements
Current Testing Requirements in Minnesota
Minnesota has no emissions testing requirements. The state's former program ran from 1991 to 1999 and tested vehicles for carbon monoxide and other pollutants in the Twin Cities metropolitan area. The MPCA instituted the tests after the EPA found CO levels in the region exceeding federal standards. Each test cost $8. Twin Cities carbon monoxide levels have been in compliance with EPA standards for over 20 years, and the MPCA has not indicated any plans to reinstate testing. If pollution levels were to exceed Clean Air Act standards in the future, vehicle testing could return. Minnesota does not require periodic safety inspections for passenger vehicles. Annual inspections are required only for commercial motor vehicles under state statute 169.781.
Who Needs an Emissions Test or Smog Check
No vehicles in Minnesota are required to pass an emissions test. The state does not enforce smog check requirements for gasoline, diesel, hybrid, or electric vehicles. There are no model year restrictions, weight limits, fuel type requirements, or geographic zones that trigger mandatory testing. This applies to all 87 counties across the state.
How Often Tests Are Required
There is no mandated testing frequency in Minnesota because the state does not require emissions inspections. When the Twin Cities program was active from 1991 to 1999, affected vehicles were tested before renewing license tabs. That schedule no longer applies.
Where Emissions Testing Is Required
No areas in Minnesota require emissions testing. The Twin Cities metropolitan area (seven-county area including Hennepin, Ramsey, Dakota, Anoka, Washington, Scott, and Carver counties) formerly required testing, but the program ended in 1999. All 87 counties now operate under the same policy.
What Happens During the Test
Minnesota does not require emissions testing, so there is no active test procedure to describe. When the Twin Cities program was operational from 1991 to 1999, vehicles were tested for carbon monoxide and other exhaust pollutants at designated testing stations. The test cost $8 and was required before license tab renewal. These procedures are no longer required anywhere in the state.
Areas in Minnesota That Require Emissions Testing
No areas in Minnesota require emissions testing. Cities such as Minneapolis, St. Paul, Rochester, Duluth, Bloomington, Brooklyn Park, Plymouth, Woodbury, Lakeville, St. Cloud, Eagan, Burnsville, Maple Grove, Blaine, Edina, Eden Prairie, Minnetonka, Coon Rapids, Apple Valley, and Mankato have no testing requirements. Rural areas across the state follow the same policy.
How the Emissions Test Works in Minnesota
Minnesota does not have an emissions testing process because no program exists. Drivers do not need to visit any station or submit test results for registration or tab renewal. If a vehicle owner wants a voluntary diagnostic check, private auto shops can perform an OBD-II scan. Fees for voluntary diagnostics vary by shop and are not regulated by the state. Results from a private scan do not affect registration status.
