What should you do when coming to a railroad crossing with no traffic controls?

Answer: B — Come to a complete stop, look both ways before proceeding

When approaching a railroad crossing with no traffic controls, it is important to come to a complete stop before proceeding. This is because there may be a train approaching and it is necessary to check both ways for any oncoming trains before safely crossing. Option A, stopping in the middle of the tracks, is incorrect as it can put yourself and others in danger. Option C, slowing down and looking both ways, may not provide enough time to react if a train is coming. Option D, honking your horn, is an unnecessary and potentially dangerous action.
