SB 2157 prohibits local governments in Tennessee from blocking access to or within designated tourism development zones, except during emergencies for first responder access or for contracted large events. It directly affects cities, counties, and tourism zones by requiring unimpeded vehicle and pedestrian access, preventing disruptions to business deliveries (including food and goods), and allowing ride-sharing services to operate normally. The law amends Tennessee statutes to ensure tourism businesses can function without local government interference, with exceptions only for verified emergencies or events under formal agreements. This bill takes effect immediately upon becoming law.
