Crossbuck Sign
The crossbuck sign is the iconic X-shaped sign placed at railroad crossings. It consists of two white boards crossed to form an "X" with the words "RAILROAD" on one board and "CROSSING" on the other. The crossbuck sign is legally equivalent to a yield sign — you must slow down, look both ways, and be prepared to stop for an approaching train. If there are multiple tracks, a small sign below the crossbuck indicates the number of tracks, which is important because a second train may come from the other direction shortly after the first one passes. Crossbuck signs are found at both active and passive railroad crossings. Active crossings also have flashing red lights and gates that lower when a train approaches. Passive crossings — which have only the crossbuck and possibly the advance warning sign — require you to rely entirely on your own observation to determine if a train is coming. At passive crossings, look both ways, listen for the train horn, and watch for vibrations or movement on the tracks. Never race a train to a crossing. If the gates are down, never drive around them — a second train may be approaching on another track.
Rules & What to Do
Treat the crossbuck as a yield sign — slow down and look both ways. Stop if a train is approaching, lights are flashing, or gates are down. At multi-track crossings, wait until you can see clearly in both directions before proceeding. Never drive around lowered gates.
Penalties
Failing to yield at a crossbuck or going around lowered gates can result in fines of $200-$500+ and 3-6 points on your driving record. Many states impose mandatory court appearances or license suspensions for railroad crossing violations.
For Commercial Drivers
Certain commercial vehicles must stop at all railroad crossings, even if no train is visible: buses with passengers, hazmat vehicles, and cargo tank vehicles (loaded or empty). Stop between 15 and 50 feet from the nearest rail. Turn off any noisy equipment to listen for trains. If driving a vehicle that's not required to stop, still slow down and look carefully — a collision between a train and a commercial vehicle can be catastrophic.
Frequently Asked Questions
What is a crossbuck sign?
A crossbuck is the X-shaped sign at railroad crossings that reads 'RAILROAD CROSSING.' It's legally the same as a yield sign — you must look for trains and be ready to stop.
Is a crossbuck the same as a yield sign?
Yes, a crossbuck sign has the same legal meaning as a yield sign. You must slow down, look for trains, and stop if a train is approaching. You don't have to stop if no train is coming (unless you drive certain commercial vehicles).
What does the number on a crossbuck sign mean?
A small sign below the crossbuck showing a number (like '2 TRACKS') tells you how many sets of railroad tracks cross the road. This means a second train could be coming from either direction.
