What should be done during a 'stop' at a railroad crossing?

When coming to a stop at a railroad crossing, the correct action is to stop 15 to 50 feet from the tracks, then look and listen for any approaching trains before proceeding. This distance is specified to ensure that you have a safe buffer between your vehicle and the tracks, allowing for a better view and sound of any oncoming trains.

Stopping at this distance also helps to ensure that if a train is coming, you are far enough away to avoid any potential collision, as trains can approach quickly and may not be visible until they are very close. Listening for any audible signals or warnings and looking for any visual indicators of a train allows you to make an informed decision about when it is safe to cross.

This method emphasizes the importance of caution at railroad crossings, ensuring that drivers are fully aware of their surroundings and the potential presence of trains, as it is not only critical for the driver's safety but also the safety of any passengers in the vehicle. The other options do not adequately prioritize safety or awareness at railway crossings, which is why they would not be the correct approach.
