Emissions Testing

Residents of Davidson, Hamilton, Rutherford, Sumner, Williamson and Wilson counties in Middle Tennessee and residents of  Memphis in West Tennessee must have their vehicles pass an emissions inspection prior to registration or registration renewal. Inspection is not required for vehicles of model year 1974 and older in Middle Tennessee. However, an inspection is required for vehicles of all model years in Memphis .

Note: A new vehicle which has never before been titled is not required to undergo emissions testing before application for the new title. You need only present the Manufacturers' Certificate of Origin (MCO) when you title and register the new vehicle at your county clerk office. Each year thereafter, however, the vehicle must undergo emissions testing before registration can be renewed.

For detailed emissions testing information (hours, locations, etc.) Visit the Department of Environment and Conservation's Vehicle Inspection Program Website. If you are in Shelby County , you may also visit the City of Memphis Motor Vehicle Inspection Bureau's website or call (901) 528-2904 for additional information.
