What is a crossbuck sign?

A crossbuck sign is a type of road sign used at railroad crossings to warn drivers of the potential presence of trains. The sign consists of a white, X-shaped board with the words "RAILROAD CROSSING" in black letters. The crossbuck sign is typically mounted on a post or pole located on one or both sides of the crossing.

In addition to the standard crossbuck sign, many railroad crossings also have supplemental warning signs such as flashing lights, bells, and crossing gates. Drivers are required to stop when approaching a railroad crossing if they see flashing lights or hear the sound of bells.

Crossbuck signs are important safety features at railroad crossings, as they help alert drivers to the potential danger of an oncoming train. It is essential for drivers to obey these signs, as failing to do so can result in serious accidents and loss of life.
