You arrive at a railroad crossing. The crossing has flashing red lights and a signal bell. You can see that a train is approaching. Which of the following are true?

When the railroad crossing signals indicate that a train is approaching, you must stop at least 15 feet from the nearest rail. (Trains are at least six feet wider than the tracks they run on, so you don't want to be too close.) Even after the train passes, the signals may continue to flash or sound and the gate may stay lowered. That may mean that a second train is approaching.
