Traffic Safety - As introduced, authorizes the commissioner of revenue to take reasonable measures to publicize the availability of the option to designate in the Vehicle Title and Registration System (VTRS) database a driver's need for assistance with expressive language or communicating needs due to an intellectual or developmental disability or medical condition; authorizes the department of safety to take such measures with respect to the voluntary designation on a driver license or identification of an intellectual or developmental disability or medical condition. - Amends TCA Title 4; Title 5; Title 6; Title 7; Title 8; Title 54; Title 55; Title 65 and Title 67.

SB 199 requires Tennessee's Commissioner of Revenue and Department of Safety to publicly promote existing options for drivers with intellectual, developmental disabilities, or medical conditions. Specifically, it authorizes these agencies to inform the public about voluntary designations on vehicle registrations (via the VTRS system) and driver licenses/ID cards that indicate a need for communication assistance. The bill amends multiple state code sections (Titles 4, 5, 6, 7, 8, 54, 55, 65, 67) to include these public awareness provisions. It does not create new disability designations but focuses on increasing awareness of currently available options for affected drivers. The measure aims to improve communication between drivers and law enforcement during traffic stops.
