You arrive at a railroad crossing whose flashing red lights and warning bells have been activated. You can see that a train is approaching. Which of the following are true?

At a railroad crossing, you must stop between 10 and 50 feet of the nearest rail if you see any of the following: a lowered crossing gate, a flashing electric signal, a STOP sign, a flag person giving you a signal, or a rapidly approaching train. You must stop even if you don't see a train. You must remain stopped until all tracks are clear, any gates are raised, and the lights are no longer flashing.
