The responsibility for managing and addressing highway trash in Tennessee primarily falls under the jurisdiction of the Tennessee Department of Transportation (TDOT). TDOT is responsible for the maintenance and upkeep of the state’s highways and roadways, including efforts to control litter and maintain a clean environment. It’s important to note that while TDOT plays a significant role, addressing highway trash is a collective effort that involves collaboration with local communities, businesses and individual residents. Public cooperation in avoiding littering and participating in cleanup activities contributes significantly to maintaining clean and aesthetically pleasing highways. https://www.tn.gov/tdot/maintenance/debris-removal.html
