Dynamic Message Signs
Dynamic Message Signs are being installed along Tennessee interstates in urban areas to provide traffic information to motorists. These signs advise motorists of traffic incidents or construction ahead so they can consider alternate routes.
Only real-time information about incidents, traffic, roadwork, weather or pavement conditions that could have an effect on driver safety and traffic flow shall be displayed on the DMS. Exceptions to this are messages that may occasionally be displayed:
- Advance notification of roadwork requiring lane closures
- Advance notification of special events that will adversely affect travel either because of added traffic generated or the requirement to close streets or highways.
Occasional messages associated with Amber Alerts or other Public Safety issues may also be displayed. Otherwise, signs will be blank.
