Final answer:
When a yellow signal light appears, drivers should prepare to stop to ensure safety and compliance with traffic rules, particularly to protect pedestrians near crossings.
Step-by-step explanation:
When a yellow signal light is shown, you should prepare to stop if you have not already entered the intersection. The purpose of a traffic signal is to regulate vehicle speeds and enhance safety for both drivers and pedestrians. Ignoring the yellow light can lead to dangerous situations, as it increases the risk of collisions and jeopardizes pedestrian safety. Especially in areas where pedestrians cross frequently, such as near schools or campuses, adherence to traffic signals is critical. Drivers who fail to slow down and prepare to stop at a yellow light not only violate traffic rules but also put others at risk.
