What is a "dynamic message sign"?
A dynamic message sign is a type of traffic sign that can display changing messages to provide real-time information to drivers. These signs use electronic displays to show messages such as traffic conditions, road closures, or weather updates. They are typically found on highways or busy roads to help drivers make informed decisions while traveling. The purpose of a dynamic message sign is to improve safety and traffic flow by offering timely, relevant information directly to drivers.
Example
When approaching a busy highway, dynamic message signs provide updates on traffic congestion and suggested alternate routes.
During severe weather, dynamic message signs instruct drivers to reduce speed and proceed with caution.
