Dynamic Message Sign (DMS)

The Idaho Transportation Department's (ITD) Dynamic Message Signs (DMS) are installed along major highways to help drivers make informed decisions, such as choosing an alternative route. They display alerts about crashes, construction, traffic congestion, and road closures. Real-time views of DMS messages are available through the Idaho 511 travel information service website and mobile application.
