what is a crossbuck sign

A crossbuck sign is a traffic sign used to indicate a level railway crossing. It is composed of two slats of wood or metal of equal length, fastened together on a pole in a saltire formation, resembling the letter "X". In the United States, the crossbuck carries the words "RAIL" and "ROAD" on one arm and "CROSSING" on the other, in black text on a white background. The crossbuck sign means the same as a yield sign, which means that if a train is approaching, drivers must slow down and be prepared to stop. The crossbuck sign is typically placed a short distance in front of the crossing and is designed to be highly visible from a distance. The crossbuck sign plays a crucial role in keeping drivers and pedestrians safe around railroad tracks.
