At a railroad grade crossing that has no warning devices or only a crossbuck sign, the recommended action is to:

• A. Stop completely before the crossing.
• B. Slow down and proceed with caution.
• C. Accelerate to cross quickly.
• D. Ignore the crossing if you don't hear a train.

Answer: (B)

When there are no warning devices at a railroad crossing or only a crossbuck sign, you must treat the crossing as potentially hazardous and proceed with extra caution. The crossbuck indicates a crossing but no active signals, so you can’t rely on bells, gates, or lights to alert you. You should slow down, look carefully in both directions, and listen for any approaching trains, then cross only if the tracks are clear. Trains can be closer and faster than they appear, and there may be little to no warning, so never rely on not hearing a train. If a train is near or visibility is limited, stop at a safe distance and wait. Accelerating through or ignoring the crossing is unsafe. The safest, recommended action is to slow down and proceed with caution.
