You are approaching a railroad crossing without signals, what should you do?

Answer: B — Stop, look both ways, and proceed with caution

When approaching a railroad crossing without signals, it is important to stop and look both ways before proceeding with caution. This allows you to check for any oncoming trains and ensures your safety. Choosing option A may not provide enough time to check for trains, option C is dangerous and puts you at risk of colliding with a train, and option D is incorrect as you should stop before the tracks, not the railway. Therefore, option B is the safest and most correct choice.
