Final answer:
True. A driver should slow down and stop if necessary when approaching a railroad crossing sign. This ensures both pedestrian and vehicular safety and helps prevent accidents.
Step-by-step explanation:
When approaching a railroad crossing sign, a driver should indeed slow down, look, and stop if necessary. This statement is TRUE. Like at a traffic signal, vehicles need to adjust their speed to adhere to signage for safety. This is crucial to prevent accidents and ensure pedestrian safety, especially near areas with high foot traffic such as schools and campuses. Failure to follow such protocols not only endangers vehicle occupants but also pedestrians and can lead to severe accidents, sometimes even resulting in loss of life. Railroad crossings are no exception, and caution must always be exercised when approaching them.
