House Bill 1912 aims to enhance roadside facilities for motorists in Tennessee by mandating the installation of signs indicating the availability of adult-sized changing tables in rest areas and welcome centers. The bill defines an "adult-sized changing table" as a powered, height-adjustable platform located in a single occupancy family restroom. If such a table is present, the Department of Transportation is required to install a sign or marker displaying a symbol that indicates its accessibility, either on new signs or by adding to existing ones near the relevant facilities. The bill also allows the Department to collaborate with the Department of Tourist Development for the design and installation of these signs, ensuring they comply with the Manual on Uniform Traffic Control Devices (MUTCD) and state guidelines.

Additionally, the Department of Transportation is tasked with publishing the locations of rest areas and welcome centers that feature adult-sized changing tables on its website. This initiative is set to take effect on July 1, 2026, emphasizing the importance of accommodating all motorists, particularly those with special needs.
