SB 2529 requires Tennessee's Department of Transportation to install signs or markers at rest areas and welcome centers indicating the presence of adult-sized changing tables (height-adjustable platforms in family restrooms). It also mandates the department to publish online a list of locations with these facilities. The bill directly affects motorists using state highways who rely on rest areas, particularly parents or caregivers needing accessible changing options. Key provisions include using standardized traffic sign symbols and consulting tourism officials for implementation, with the requirement taking effect July 1, 2026.
