What must a driver do at a railroad crossing?

A driver must slow down, look for trains, and proceed only when it is safe to do so at a railroad crossing because safety is the primary concern in this situation. Approaching a railroad crossing requires caution as trains can come at high speeds and are often quieter than expected. By slowing down and looking for trains, drivers have the opportunity to assess the situation accurately, ensuring that they can make a safe decision. Railway crossings are equipped with signals and signage that indicate when it is safe or unsafe to cross, and being vigilant is crucial to prevent accidents.

The other options present actions that could lead to dangerous situations. Accelerating quickly to cross presents a risk of not having enough time to react to an oncoming train. Ringing the horn does not guarantee safety and may lead to complacency if a driver continues without ensuring it’s safe to proceed. Finally, stopping and waiting for two minutes is unnecessarily long and does not align with safety protocols, which focus on quick assessment and appropriate action rather than arbitrary waiting periods.
