A railroad crossing sign is typically a yellow, circular sign with a black “X” and the letters “RR” on it (in the United States). This sign warns that train tracks cross the road ahead, so you need to be prepared for the possibility of a train and a stop ahead.
Key points about what it warns and what you should do:
It alerts you to slow down and look/listen for trains as you approach the crossing. Even if you don’t immediately see a train, you should approach the tracks cautiously.
As you get closer, you’ll often see the actual crossing markers, which are usually a white X-shaped sign that says “Railroad Crossing” (called a crossbuck) at the tracks. Many crossings also have flashing red lights, and some have gates that come down when a train is approaching.
When you see the initial round yellow RR sign, it’s typically a few hundred feet before the tracks (distance can vary). This gives you advance notice to stop if necessary. You should never try to “beat” a train. Trains are usually moving faster than they appear and can’t stop quickly.
By law, certain vehicles (like school buses and trucks carrying hazardous materials) must always stop at railroad tracks, so be aware that a vehicle in front of you might stop even if a train isn’t visible yet.
If a train is coming, you must stop at least 15 feet (and no more than 50 feet) from the tracks (there are usually painted lines or signs indicating where to stop).
If the crossing has no lights or gates, the yellow warning sign and crossbuck might be your only alerts, so it’s on you to look both ways down the track for any approaching trains.
In summary, the railroad crossing sign is warning you that you are approaching a train crossing. You should be prepared to stop if needed, and proceed only after ensuring no train is coming. Always obey any signals (flashing lights/gates) at the crossing. Remember: a train always has the right-of-way, and they can’t swerve or stop quickly. It’s up to drivers to yield to trains.
