Emissions Testing

Please visit www.nashvillevip.org for information on the reopening of emissions testing centers in Davidson County.

Vehicles are inspected annually and can be tested within  ninety (90) days of the registration’s expiration date.  The fee for an emissions test is $9.00.

Take your vehicle along with the renewal notice you may have received in the mail from the Tennessee Department of Revenue, to one of the vehicle emissions testing stations.  A renewal notice is not mandatory to have your vehicle tested.



For hours and locations of emissions testing stations or specific information about emissions tests, please call 1-866-623-8378 or visit their website by clicking here.

The emissions testing facilities get busy on the first and last days of the month.  To avoid the long lines, the best time to get your emissions test is within  ninety (90) days prior to your expiration date and in the middle of the month.

The federally mandated emissions inspection program is operated by Opus Inspection and is not a part of the Metropolitan Government.

Failed Emissions Test

Vehicles not passing the inspection will receive a vehicle inspection report with the reason(s) the vehicle is failing. After appropriate repairs are made to the vehicle, one free retest is available within ninety (90) days of the initial inspection.  If you have your vehicle tested PRIOR TO THE EXPIRATION OF YOUR TAGS, and it fails, you are allowed a 30-day grace period from the date your tags expire in which to have your vehicle repaired, receive a passing emissions test and renew your tags.  For more information refer to: www.nashvillevip.org/NashvilleVIP/site/whatifufail.htm.
