You are approaching an intersection where the traffic light has turned yellow. What should you do?

A yellow (amber) traffic light means the signal is about to turn red and you should stop if you can do so safely. The yellow signal exists to give drivers time to clear or stop at the intersection — it is not an invitation to accelerate. The decision is judgment-based: if you are far enough from the intersection that you can stop without hard braking, do so. If you are so close that stopping would require slamming the brakes and possibly being rear-ended, proceed cautiously through. Speeding up to beat the light is dangerous because cross-traffic begins entering the intersection as soon as the light turns red. Some intersections also have red-light cameras that ticket vehicles entering after the light turns red.
