What does a yellow traffic light mean?

Answer: B — Caution, prepare to stop

A yellow traffic light serves as a signal for drivers to approach an intersection with caution and prepare to stop. It indicates that the light is about to change to red, which means that vehicles should not enter the intersection if it is safe to stop. This warning is designed to give drivers time to react to the changing light to maintain safety on the road. This concept is crucial for ensuring that drivers are aware of and anticipate traffic signal changes, thereby reducing the risk of accidents at intersections. Understanding the implications of a yellow light can significantly improve driver response times and decision-making while on the road.
