What is the proper action to take when you see a yellow traffic light?

Answer: B — Slow down and prepare to stop

When approaching a yellow traffic light, the proper action is to slow down and prepare to stop. The yellow light serves as a warning that the signal is about to change to red, indicating that vehicles should be ready to stop safely. It is important for drivers to react appropriately to this signal to ensure safe traffic flow and to prevent potential accidents. Slowing down allows you to assess the situation, gauge the behavior of other drivers, and come to a safe stop if necessary, rather than risking running a red light, which can lead to dangerous encounters at intersections. Choosing to speed up, maintain speed, or change lanes immediately in response to a yellow light does not account for the potential risks involved, such as misjudging the timing of the light change or creating abrupt movements on the road that could lead to collisions.
