What is the function of a crossbuck sign?

A crossbuck sign is specifically designed to indicate a railroad crossing. It is usually a white sign with an "X" shape that displays the words "Railroad Crossing." This sign serves the crucial function of alerting drivers and pedestrians that they are approaching a location where railroad tracks intersect with the roadway. This warning is vital for safety, as it helps to prevent collisions between vehicles and trains.

Understanding this is important for drivers, as they must approach these crossings with caution, looking for any approaching trains. The sign does not inform drivers about school zones, traffic control instructions, or road construction, which are indicated by different types of signs. Knowing the purpose of specific road signs like the crossbuck helps ensure safe driving practices and enhances overall road safety.
