What must drivers do when approaching a railroad crossing?

When approaching a railroad crossing, drivers must slow down, look both ways, and be prepared to stop. This is vital for several reasons. First, trains can travel at high speeds and may not be visible until they are very close to the crossing, making it essential to be vigilant. Slowing down gives you time to observe the situation and ensure it's safe to proceed. Looking both ways allows a driver to check not just for oncoming trains, but also for any other potential hazards. Being prepared to stop is crucial as a train's approach may not be immediately apparent, and safety must always come first.

Other actions, such as speeding up to cross quickly or only looking in one direction, could lead to dangerous situations since they do not allow for thorough observation or consideration of safety. Continuous horn usage would not contribute to making a safe decision at a railroad crossing and may create confusion or panic. Therefore, the approach to a railroad crossing should always prioritize caution and awareness.
