A variable message sign (VMS) is a traffic control device whose message can be changed manually, electrically, mechanically, or electromechanically to provide motorists with information about traffic congestion, traffic crashes, maintenance operations, adverse weather conditions, roadway conditions, organized events, or other highway features (e.g., drawbridges, toll booths, weigh stations, etc.). A variable message sign may be referred to as a changeable message sign (CMS) or a dynamic message sign (DMS) in some publications. VMS types and design considerations are addressed here, as well as siting considerations. Details on displaying, altering, and removing messages are also provided.
