Final answer:
Traffic signals are important for regulating vehicle speed and enhancing pedestrian safety. An intersection with a history of speeding and accidents benefits from a traffic signal to reduce risks. Special circumstances, like a medical emergency, can present exceptions to following traffic rules at an intersection.
Step-by-step explanation:
The statement provided outlines the considerations and potential benefits of installing a traffic signal at an intersection where currently many vehicles speed through without regard to the posted speed limits. Installing a traffic signal is expected to slow down vehicles, thereby enhancing pedestrian safety and potentially reducing the frequency of accidents. Specific situations, such as the urgent need to transport a pregnant woman to a hospital, might present moral dilemmas regarding the adherence to traffic rules.
Furthermore, the increased number of accidents at the intersection, including those resulting in fatalities, underscores the necessity of having a traffic control mechanism in place. A traffic signal would not only regulate vehicle speeds but also provide safe passage for pedestrians, significantly contributing to overall road safety.
