Final answer:
You should prepare to stop when you see a yellow traffic signal to increase safety and comply with traffic laws. This supports the purpose of traffic signals in managing traffic flow and reducing accidents.
Step-by-step explanation:
When a yellow signal light is shown, you should prepare to stop if you have not already entered the intersection. This guidance is designed to enhance the safety of both motorists and pedestrians by allowing sufficient time to slow down and stop safely, as opposed to accelerating to beat a potential red light, which could increase the risk of an accident. Traffic signals are effective tools for managing the flow of traffic and improving safety. As the number of accidents at an intersection rises, particularly those resulting in fatalities or serious injuries, the installation of traffic signals becomes an increasingly critical measure to control speed and facilitate safer crossing for pedestrians.
