What does a crossbuck sign indicate at a railroad crossing?

• A. A Warning That A Railroad Crossing Is Ahead
• B. A Detour That Requires You To Turn
• C. A Caution Sign For Pedestrians
• D. A Railroad Crossing

Answer: (D)

A crossbuck at a railroad crossing marks the location of the crossing itself and tells you to be prepared to stop for trains. It’s the standard sign that indicates you’re about to encounter train tracks, so you should slow down, look both ways, listen for any approaching trains, and be ready to stop if the lights or gates are active. It isn’t a detour sign, nor a pedestrian-only caution; it’s the crossing marker that applies to all road users. If there are additional warning devices like flashing lights or gates, those work in tandem with the crossbuck to signal you to stop.
