Drive Through Registration Renewal

No appointment is necessary for registration services at Clean Air Car Check’s Partial Service License Branch.  Drive-in during regular business hours, even if you don’t need an emissions test. There is an additional convenience fee for BMV services at an emissions testing facility.

Animals are not allowed in the vehicle during the testing procedure.  If an animal is with you, you will be asked to take them and wait outside the building during the testing procedure.

Helping Indiana eliminate harmful pollutants that affect the air we breathe

Locations & Hours

Indiana is making steady progress toward reducing emissions of pollutants from industry, motor vehicles and other activities that contribute to the formation of ground level ozone in Lake and Porter counties.

The Clean Air Car Check program identifies vehicles that emit harmful pollutants and once repaired, those vehicles’performance and fuel economy are improved, as is the air we breathe. Properly maintained vehicles also result in less contamination being released into the groundwater.
