Just found this tidbit here: https://www.tn.gov/safety/news/2020/3/19/tennessee-department-of-safety—homeland-security-s-driver-services-division-announces-service-updates.html
All Driver Licenses, Learner Permits, Commercial Driver Licenses, Photo Identification Licenses (ID), and Handgun Carry Permits that would expire between March 12, 2020, and May 19, 2020, will be extended for six months from the original expiration date. The Department will issue a letter of extension to the individuals affected. Affected individuals will be required to keep the letter with them during the extension period.
Hopefully if you’re in this category, you’ve already received your letter.
