American Fire Station Sign In The States these road signs alert motorists that they are approaching a fire station or an intersection where fire units are likely to emerge from. Some signs have a set of amber warning lights that will flash when activated by an emergency vehicle's Opticom, a device that sends a signal from the fire engine to a receiver on or near the sign. Opticom's can also change traffic signals to green in the direction of the fire engine's travel prior to the unit's approach, aiding in efficent response. They work properly about 75% of the time. This particular sign is located close to the Alto-Richardson Bay Fire Station in Marin County, California.
