What does a yellow traffic light signal indicate?

Answer: B — To prepare to stop

A yellow traffic light signals that a driver should prepare to stop. This warning light indicates that the signal is about to change to red, which means vehicles must be ready to halt before reaching the intersection. The purpose of the yellow light is to give drivers a brief opportunity to react and make a safe decision about whether to stop or continue through the intersection, depending on their distance from it. Choosing to stop is essential, as it helps maintain safety for both drivers and pedestrians. It also prevents potential accidents that could occur if a driver were to disregard this signal and enter the intersection when the light turns red. Understanding the role of a yellow light can help drivers anticipate the actions of other road users and navigate traffic safely.
