Extinguishable Message Sign (EMS)

Extinguishable Message Sign (EMS) provides a clearly visible fixed message to en-route motorists. Strategically placed, this sign improves overall safety by providing motorists with pertinent roadside information or warnings. Commonly used EMS applications include safety information near airports, data regarding direction or availability for carpool lanes or toll roads, radio frequencies for advisory radio stations, and general traffic alerts. SWARCO McCain’s EMS signs are the perfect addition to your overall Intelligent Transportation System (ITS) and can improve traffic flow and safety in your jurisdiction.
