What action is required at cross buck signs?

1. You must yield to the right-of-way of the train

2. You can proceed without stopping if no train is visible

3. You are allowed to pass through after looking

4. Only stop if a train is approaching

The correct answer is: You must yield to the right-of-way of the train

At cross buck signs, the essential action required is to yield the right-of-way to trains. This is crucial for safety because trains have the right-of-way over all other vehicles. The cross buck sign is a clear indication that you are approaching a railroad crossing, where the potential for trains to be present is a significant risk. Yielding means you must give way to any train that may be coming, regardless of whether you can see one at the moment. This ensures that you are taking the necessary precautions to prevent accidents at these dangerous intersections. It is important to understand that while you may not always see a train, it could arrive suddenly, and strict compliance with traffic laws at these signs helps protect both operators of motor vehicles and those on the train. While some options suggest proceeding without stopping or looking before passing through, they do not account for the inherent dangers of railroad crossings. The correct action emphasizes caution and awareness, ensuring safe passage through these areas.
