Step-by-step explanation:
A crossbuck sign is a type of road sign that is found at highway-rail intersections. It serves as a yield sign, indicating that drivers must yield the right of way to trains. When approaching a railway crossing, drivers should slow down, look and listen for trains, and come to a stop if a train is approaching.
In cases where the road crosses over more than one set of tracks, there may be a sign below the crossbuck indicating the number of tracks. This helps drivers to be aware of the multiple tracks at the intersection.
