What does a yellow traffic light indicate?

Answer: B — Caution; prepare to stop

A yellow traffic light serves as a warning that the light will soon change to red. It indicates caution and alerts drivers to prepare to stop. This signal is intended to give drivers enough time to safely slow down and stop their vehicles to avoid running a red light, which could lead to accidents. While some drivers may feel tempted to speed through a yellow light, the key purpose of this signal is to promote safety by allowing adequate time for stopping. It’s important to recognize that the yellow light is not an invitation to accelerate, but rather a cue to begin reducing speed and to watch for the change to a red light. Understanding this can help prevent traffic violations and enhance overall road safety.
