Final answer:
When a green light changes to yellow, if in the intersection, you should continue moving and clear it safely. Pedestrian safety and accident reduction are key reasons for the importance of obeying traffic signals.
Step-by-step explanation:
If you are already within the intersection when a green light changes to yellow, you should continue moving and clear the intersection safely. A steady yellow traffic signal light is a warning that the light will soon turn red, which indicates that you should prepare to stop if you can do so safely; however, if you are already in the intersection, it's important to clear the intersection to avoid causing congestion or a potential accident.
Increasing speed to beat the light change is dangerous and may lead to accidents, not only with other drivers but also with pedestrians, especially in areas with high foot traffic such as school zones or campuses. Traffic signals play a crucial role in maintaining road safety by managing the flow of traffic and providing safe crossing points for pedestrians. They help to slow down vehiclesand significantly reduce the number of accidents, which is a primary reason for their installation at busy intersections.
