Final answer:
When approaching an intersection, one should look for a traffic signal which ensures pedestrian safety and encourages vehicles to obey the posted speed limit, thus reducing accidents.
Step-by-step explanation:
The first thing to look for when approaching an intersection is the presence of a traffic signal. Traffic signals are essential for coordinating the movement of pedestrians and vehicles to ensure safety. Pedestrian safety is a critical issue, especially in busy areas such as school campuses where many students and others must navigate across roads. The installation of a traffic signal is beneficial as it compels vehicles to adhere to the posted speed limit and provides pedestrians with safe and designated times to cross, thereby reducing the risk of traffic accidents and enhancing overall safety.
