Final answer:
Drivers must stop if necessary, obey crossing guards, and watch for children when approaching the sign. Installing traffic signals can improve safety by controlling vehicle speeds and facilitating pedestrian crossing, thereby reducing accidents at intersections.
Step-by-step explanation:
When approaching the sign mentioned in the question, drivers have a responsibility to ensure the safety of the road for both themselves and others, including pedestrians. The correct action to take includes: stopping if necessary, obeying signals from crossing guards, and slowing down and watching for children crossing the road. Ensuring pedestrian safety, especially near campuses where many students cross, is critical, as is adhering to posted speed limits to prevent accidents. The introduction of a traffic signal at a problematic intersection is often a solution to manage vehicle speeds and provide safe crossing times for pedestrians. It can significantly reduce the number of accidents which, if too frequent, can lead to serious consequences, including the loss of life.
Moreover, a traffic signal installation can be motivated by various situations that pose risks to safety. These include vehicles speeding through an intersection without regard to the speed limit, the need to dodge traffic for crossing pedestrians, and the occurrence of a high number of accidents at the intersection. A functioning traffic signal helps prevent such incidences by providing structured crossing times and slowing down traffic.
