What is a crossbuck?

A crossbuck is a sign that indicates the presence of tracks at railroad crossings. This particular type of sign is essential for alerting drivers to the potential approach of trains and the need to exercise caution. The crossbuck is typically shaped like an "X" and prominently displays the words "Railroad Crossing," making it easily recognizable to motorists.

The primary purpose of the crossbuck sign is to ensure safety by informing drivers that they are approaching a location where they must be vigilant for oncoming trains. Unlike traffic signals, which manage the flow of vehicular traffic at intersections, or warning lights that may indicate other hazards, the crossbuck specifically denotes interaction with railroad tracks. Thus, understanding the role of crossbucks in roadway signage is crucial for safe driving in areas where railroads intersect roads.
