If you have a vehicle that is out of the State or the testing area when tags are due for renewal, you can apply for a vehicle exemption from the emissions testing requirement. To receive an exemption, a completed application form with documentation must be submitted to the Division of Air Pollution Control for processing.

When the vehicle returns to the testing area, you must have the vehicle tested, and pass an emissions test. Failure to do so may result in no future exemption being granted for the vehicle. For more details, you can call (615) 532-8378 or toll-free 1-866-329-9632. Please review instructions before submitting your application form.
