Final answer:
Drivers are advised to look, listen, and slow down when approaching an unguarded railroad crossing to improve road safety and protect pedestrians, in light of the common issue of speeding vehicles and a history of accidents at such intersections.
Step-by-step explanation:
When approaching a railroad crossing that lacks warning signals, such as electric flashing lights or gates, it is crucial for drivers to be extra cautious. Engaging in the practice of looking and listening for oncoming trains and slowing down is essential for road safety. This approach helps prevent potential collisions with trains, something especially important considering that many vehicles tend to disregard the posted speed limit at intersections. Moreover, pedestrian safety is also a concerning issue.
At intersections near campuses, students and others frequently need to navigate through traffic to cross the streets. Implementing a traffic signal could considerably improve safety by guiding when it is safe to cross, thereby reducing the need to dodge traffic. Finally, the installation of a traffic signal can significantly decrease the accident rate at such intersections, where there has been an unsettling frequency of accidents and even loss of life.
