What does it mean if a traffic light turns yellow?

• A. The light is about to turn red, so prepare to stop
• B. You may speed up to clear the intersection
• C. The traffic flow is normal
• D. You must wait for the green light

Answer: (A)

When a traffic light turns yellow, it serves as a warning that the signal is about to change to red. This indicates that drivers should prepare to stop safely if they are in a position to do so before reaching the intersection. The yellow light is a critical signal intended to increase safety by communicating that the opportunity to proceed is ending and that caution is required. This function of the yellow light is important for preventing accidents by ensuring that drivers do not proceed through an intersection when the light has officially changed to red. For drivers who have already entered the intersection when the light turns yellow, they are expected to clear the intersection safely if they can do so without speeding. Thus, the emphasis is on awareness and preparedness, rather than acceleration or waiting.
