Final answer:
Yes, drivers must yield to crossing trains at railroad crossings to prevent accidents, as trains have the right of way and cannot stop quickly.
Step-by-step explanation:
Drivers must indeed yield to crossing trains at railroad crossings. This is not only the law, but it is also a necessary safety measure to prevent collisions and potential casualties. When a train is approaching a railroad crossing, vehicles must stop at a safe distance from the nearest rail and wait for the train to pass completely before proceeding. Railroad crossings are typically marked with signs, lights, or gates to alert drivers of an approaching train. Ignoring these signals and failing to yield can result in serious accidents, as trains cannot stop quickly and have the right of way due to their size and speed.
